Pilot for the C-64 does sound much more plausible, yes.. And likewise, I
thought it was a very nice idea.

But hm.. other than formatting text, don't both the VIC-20 and C-64 share
the same CBM BASIC version? No reason that PILOT for C-64 couldn't run on
VIC, with enough memory expansion, I'd think?

Speaking of LOGO (and the Terrapin..), I assume PILOT is still around in
some form? Correct me here, but I believe that a +BASIC+ implementation of
PILOT was released for either the VIC-20 (??) or the C-64. I recall typing
it in, back in the early 1980s, just for kicks.

Could that actually have been for the VIC? An admittedly simple (and

…and that was the issue with the F4 Phantom during Vietnam.  The F4 was 
designed to take out aircraft with its missiles.  Except that didn’t work too 
well.  The USAF decided after Vietnam that all “fighters” would have a “gun” of 
some sort.  I guess they forgot that lesson.

   about the fact that it's beaten (badly) in simulations and exercises with
   much older fighter aircraft with much more "primitive" tech, including

Oh, just to add more, the F35 is not a "fighter" despite its 
designation.  It is an air superiority platform that is 
never supposed to get into a dogfight.  It is supposed to be 
in a network of planes, and agressors will be shot down by

OK, the whole concept with the F35, if they can ever get it

It is a SYSTEM of planes.  So, each pilot can see what ALL 
the other aircraft in the region see.  If one guy spots a 
new SAM site, he can mark it, and they ALL now know it is 
there.  Some F35s can go "dark" and shut off their RADAR 
transmitter, and use other aircraft's transmitters to 
illuminate their target.  All sorts of advanced stuff like 
that will make it a formidable system, but it all depends on 
a huge amount of software and communications systems to all

churning out all the myriad assemblies of IBM 360 systems, 
processors, channels, memory, peripherals, etc.

(OK, we know that being a dumb desk ornament, they probably made some
number of 100 Millionth SLT module, but the point is clear). Oh, and
the desk ornament is dated fairly early in the game!


IBM
sent out a letter to all 360 users who had machines under contract, giving a
date when they would no longer guarantee that any particular machine could
be repaired, due to lack of spare modules, and a second (later) date when

Typical IBM.
Well, it was pretty much commanded by the US government.  
Remember, they had to keep 360s running until 1989!  YIKES!

replacement would drag on for that long.)
SLT and S/360s did indeed have teething problems. It took 
a while to get the bugs out of the system. 
Yes, but I'm sure once they DID get manufacturing of of SLT 
working, they had a way to make lots of logic at a cost much 
lower than all the other computer makers who were still 
stuck with little metal-can transistors and glass diodes on 
PC boards.

But, I'll bet that oxygen and moisture will continue to take their toll at a
slower rate.  Remember, all this gear is now about 50 years old!

IBM SLT cards and modules seem to do well - I have picked up more than
a few that were exposed to the elements, and if they are not beaten up
(curse those crappy thin aluminum covers they used!), moisture tends
to not be a big issue, thanks to the silicone goop underneath.

I looked at some stuff from the disk lab in Rochester, MN. 
(I think) that was given to Washington University some years 
ago.  It had all been stored in good conditions.  WU wanted 
the air bearing fixtures and a few other things, but had no 
interest in all the gear that ran it, Series/1 and racks of 
SLT boards.  Some of the aluminum covers could be flicked 
off with your fingernail..The green epoxy that held them on 
had started to go bad, I guess.


Some of the guys who reported earlier on 1800 systems seemed 
to think they were a LOT more reliable than my experiences 
watching 360/50 and 360/65 reliability.  It might be that 
the 1800 had shorter stacks of boards to be cooled in the 
same airflow.  I know the /65 had a tall stack, and some of 
the areas of the CPU had pretty hot air coming out the top.

Those were the days when Kelly came up with an idea that was needed now,
and most things were done at the Skunkworks. If something was farmed out,
the company probably had no idea what the product was for. Everything was
done quickly and efficiently, without most of congress knowing. I heard,
but never verified, that right out of school he designed the P38, and who
knows what else before the U2.

One word: Therac.



Therac is not the same threat at all. What seems to be missing from the 
process that leads to specifying Windows is, indeed, threat modelling. 
The threat of a virus scanner disabling the machine is not the same as a 
virus disabling the machine, and so on (a proper enumeration of threats 
would be quite long).


The point is that the threat model for a "discrete stupid device" is 
VERY different from the threat model for Windows. Human error obviously 
appears in both lists (and can be mitigated!) And these aren't the only 
2 options, either...


I think we can all agree that when the outcomes are as bad as this, then 
the engineering process was faulty. A virus scanner (or virus) is a very 
easily foreseen problem.

Logo has this persistent reputation, but it's actually a very complete FP
language even if the syntax is a little stilted. It has a lot in common
with Lisp and it can be considered a true descendant of it.

The problem is few folks use it anymore because of its stereotype as being
strictly pedagogical and it's not well-suited to programming in the large, so
it doesn't give him much room to grow.

There's also a lot of "bad practices" and for whatever reason I see them
more with Windows installations. Microsoft, to its credit, is making it
harder for people to screw up by default.

During my consultant slut days, I was tasked with building the ODBC backend
for a campus resource management system and the vendor specified SQL Server,
so that's what I did. After I hung up my hat on that job, Code Red blew
through and knocked off all the Windows servers on the administrative
network ... except that one. They did a forensic analysis and discovered
the reason "my" box didn't fall victim was I had written a very restrictive
set of file-sharing permissions instead of accepting the Windows default.
The worm couldn't get in.

It never occurred to the other admins to do that.

The main issue I had was migrating code to the next version of windows 
or the development environment.
We had a lot of code that talked to accounting systems. In particular a 
UK product called Sage.
Imagine having to take care of  version changes in windows, visual basic 
and Sage all at the same time.


The big change was the move from vb to vb.net. That is to say to object  
oriented programming.
Microsoft were a little naughty in saying it was the next version of vb. 
It wasn't. It was a whole new ball game.
In my part of the industry over half of the commercial  vb programmers 
took one look and retired on the spot.


Me ? well I loved it.  Once you grasped the ideas then you could do so

They gave away the development environment because the code only ran

Points to multiple links on the “Gertboard” accessory. That adds lots of

The Raspberry Pi can also run (and has available, for free) an early version of

And ultimately, the whole purpose of the RPi was for this sort of education.  
There are lots of Pi-based kits out there created for this very purpose. E.g.:

  https://www.adafruit.com/products/955

  https://www.adafruit.com/products/1538

  https://www.adafruit.com/products/3058

  http://www.canakit.com/raspberry-pi-3-ultimate-kit.html

raspberrypi.org has tons of material aimed at that age group, both software and 
hardware hacking.

For Arduino:

  http://www.canakit.com/arduino-professional-kit.html

http://www.canakit.com/sparkfun-inventor-s-kit-for-arduino-with-retail-case.html

With Arduino, you need a separate host computer to write/download the code 
on/from.  But the Arduino kits are much more oriented towards physical 
interfaces, and I defy you to introduce me to an eight-year-old who doesn't 
want to build robots! :-)

I believe you are right and I think Logo used to be taught in schools.
Unfortunately, I never learned Logo myself. I do have a copy of the IBM Logo
around here somewhere. I think thought Logo might be a bit too simple.
Unfortunately, time is something that is a precious commodity and as others
have pointed out there are far more useful languages for him to learn (in
fact his school has a coding class that teaches some more modern languages -
I don't think they even have a BASIC lab like we did back in the 80s/90s.)
So as cool as it would be for him to know Logo and other older languages I
want to expose him to simple programming and if he shows interest he can
move on to more useful stuff.

Yeah, kids these days, as a general rule, are not that interested. There is
too much instant gratification for them to bother coding 10-20 pages worth
of code (like you used to find in magazines) to get a program to run. That
being said I would love for him to at least understand the building blocks
(binary vs. decimal, notations, etc.)

At this point my concern is more getting him interested in being more than

Tell me about it. In the age of streaming and instant gratification nobody

I agree with giving him problems - but he is eight and has no idea what "pi"
is (outside of something you eat) much less how to calculate it. I am
thinking giving him simple problems and more importantly tools to entertain
himself. If he can write simple programs that he can show off to friends
that will keep him interested.  Of course I have a feeling I will see a lot
of:

10 print "What is your name?"
15 input N$
20 print N$ "made a stinky fart"
30 goto 20

I agree that this is key! I want it to be an interactive experience and not
another electronic distraction ala PS3/iPad/etc. He is actually still
interested in some of the older games even though the graphics are not
fancy. So there is still hope that he can be kept from all the distracting
fancy graphics and focus on the meat of the problem. I think once he gets a
bit of success running things then he may want to pick up on it himself.
Right now the biggest hurdle is going from an iPad which is very intuitive
to DOS which his very intimidating so he is put off.

I would say very few. You have to remember critical systems are not running
a general windows system i.e. people are not surfing the web on them and
installing the latest games recommended by friends from facebook. Windows on
its own is very stable. I.E. if you take a clean install of windows SW on
recommended HW and just use the built in apps and never go on the internet
it will run without any issues. Medical HW makers are basically using
recommended HW, building one application on top of the OS, and test the hell
out of it. Since they limit the HW, SW, and modality of use it runs stable.

Almost all (maybe 80%) of your medical HW is probably running some flavor of
windows.

Pyxis/Omnicell: Windows CE
Sonosite: Windows 2K or XP
EMRs: Windows XP or 7 (usually virtualized through Citrix).

Heck DOS is still around too!

The more specialized equipment (fluoro machines, MRI/CT, etc.) usually have
their own OS although I am seeing C-Arms w/ windows back bones now a days as
well. As the focus is going toward cost saving more and more generalized
HW/SW is being used. After all why re-invent everything for each device when
you can use windows to run the HW, network, input, etc. and just have the
medical device (e.g. ultrasound probe) act like a peripheral with its own
drivers.

Where windows causes an issue for the hospital is in the general business
areas (HR, accounting, administration, etc.).

No they don't because they don't have LAN ports or USB ports - at least not
one's easily accessible by RNs/MDs/etc. They are single purpose machines
that are locked down very well and they are being used by people who are not
interested in getting them to do things they are not designed for. Again, I
have not seen a blue screen on a critical piece of equipment in 14 years.
Walking by the RN station and looking at the computers they use to chart -

I was going to suggest he introduce the lad to a wide range of languages, 
especially non-procedural ones, and outliers such as Forth and APL.  It's much 
easier to grasp the concepts (and joy) of things like functional programming if 
you're exposed to them before confirmation bias limits your acceptance of the

My ER experience was back in the Windows XP days. I have noticed 7 seems

Windows 10.

Hmm, well you do make a good point. I'm not sure Linux would give better 
results, but it certainly has a better reputation for stability and that's 
been mirrored in my experiences, also. However, to be honest what I'd be 
most impressed by seeing would be either thin clients running Windows CE 
or (even better) modern terminals connected back to a 
redundant-as-all-heck mainframe or overbuilt server (think high end HP DL 
boxes) in a fully clustered or redundant system. People might complain 
that the only thing they can do on the terminals is their job, but uhm, 
isn't that why they are there?

Hmm, that's not my experience, but I'm not a sales guy. IIRC, the last 
time I saw Windows Server and RHEL pricing compared side by side, it was 
either close in many cases or quite a bit cheaper on the RHEL side. I'm 
not a RHEL shill by any stretch, but just sharing what I've seen. Maybe 
you mean desktop machines? That could make sense, I suppose.

Well, let me focus on that last sentence. I really couldn't agree more on 
that. I'm sure one could take something like OS/2 and, even though it's 
completely out of support, you could easily make it work if you put the 
right plans in place (spares, 3rd party support, adequate staff with good 
shift coverage and high morale). It's really hard to overstate how 
important those "other" things are, versus just the choice of OS.

Yes, quite correct and the tagline for the list is:

"General Discussion: On-Topic and Off-Topic Posts"

I'm going to call discussions of the relative merits of C coding "general 
discussion" and we'll say the curmudgeon bits are "off topic" if you like. 
It still seems to fit the list quite nicely. 

Also, to be fair:

1. Some of that discussion spawns other threads about classic hardware. 
Observe folks talking about hardware memory tagging features in classic 
systems to aid with GC and other items of discussion. 

2. Programming and computers are a bit hard to separate. Classic computers 
had classic languages, too. Witness the discussions on BLISS, BCPL, and 
older implementations of FORTRAN and COBOL that runs on classic machines. 
My point is that it's not really all that off-topic. 

curmudgeon (noun):
a bad-tempered or surly person.

Wouldn't complaining that people are going off the rails qualify as surly? 
Just sayin'  :-)

Omen Technologies

I don't know if anyone else has been working this, but at least I have been
following up occasionally with the Omen Technologies owner. Current status
(as of yesterday), she is selling the domain name and looking for "big
bucks", which I suspect "omen.com" will probably fetch. She wants that done
first, to make sure that the domain passes hands completely unencumbered
with regards to any other Omen Tech stuff (IP, licenses, etc.). Once that
happens, then she'll look to work on the machine holding the docs/software
that were public facing (it also houses personal/private info that needs to
remain so).

 

That machine has hardware issues and many passwords are not known. However,
it won't be touched until the domain sells. After that. work will begin.

 

Just thought some folks might want to know status..

I learned a language called "Logo" first. It was taught by volunteer 
instructors at a local community center. I was 7, and the minimum age was 
supposed to be 10, but they let me in anyway. I enjoyed it. It came with a 
few media functions that made programming more fun since it was pretty 
easy to make music or games. Plus it was a little less sphghettish than 
BASIC. There are tons of Logo interpreters and books for kids. I get the 
feeling it's geared exactly toward teaching children. Everyone loved the 
turtle.

> I'm only 10% kidding lol

I learned ASM as a kid (I've never become that great at it, but I get by). 
As a child, I had so few people around who knew anything about computers, 
nobody was there to say "that's too hard". I had a book that came with a 
timex 1500 my mom got at a garage sale. I just picked it up and started

Given that the email address is from "Northrop Grumman" I'm guessing it

Ew - apologies, been top-posting all day to my other email correspondents, 
please stand on your head while you read my last post ;-).

Jay has a great point. With PC-XT class hardware, he will want to do things 
faster. If some of your tasks for him are suitable for short assebly language 
programs, and he can make them happen 100 times faster than in BASIC, that 
might grab his attention. 

Of course, rather than expose him to 8088 assembler, I’d recommend you run 
right out and grab a used TRS-80 Color Computer - cheap, and 6809 assembly is 
very very nice - no segment registers.

The downside of *that* is that if he ever decides to use the “Sign Extend” 
instruction, you’ll have to have a talk with him about the birds, the bees, and 
where little subroutines come from :-).

Seeking Sanyo CRT-70 RGB monitor in the US

2016-05-27 Thread Adrian Graham

Folks,

I've been contacted by someone wanting to recreate these monitors and is
wanting to buy mine but I can't sell it since it's the only one I've got and
apropos of nothing shipping a glass tube across the pond without expensive
packing/dismantling isn't really an option. He claims mine is the only one
he's seen in 5 years of searching, are they really that rare?

This is mine, matching its MBC-555 PC nicely:
http://www.binarydinosaurs.co.uk/Sanyo_MBC555.jpg

Speaking to him tonight he really only wants to borrow one for taking a
casting of the front bezel so has anyone over there got one to lend/rent to
him? I think he's in CA but will check if necessary.

Cheers!

Re: Need Rec: Book to teach about computers and BASIC at an eight year old level

2016-05-27 Thread Tapley, Mark

Ali,
generating interest in the topic is probably the single most critical 
step you will take. That is where I’ve had the most trouble, and from your 
first paragraph, sounds like that is your first stumbling block, too. Here are 
things that might help:

1) Provide him with problems (lots of them!) in other areas that the PC-XT / 
basic combo can solve for him. Give him math homework with iterative solutions, 
ask him to calculate the value of pi or find the first 500 pythagorean 
triplets, or something like that. Then help him through solving those problems, 
and pose him more problems to solve himself. This will take a lot of time on 
your part.

2) Demonstrate that *you* are interested in it - play nim or trek or hammrbi 
for a couple of hours, or write your own computer game on it, with him watching 
over your shoulder. Let him help, 

Make sure that the interaction between you and him is the primary goal, 
and BASIC and the computer are secondary, while you do this. He is hard-wired 
to resist the idea of you foisting him off on a machine and then walking away 
while he “learns” - in relational terms, that will feel like a punishment to 
him. On the other hand, if the computer and the lessons form environments that 
establish better connection between you and him, he will like it. 

My 2 cents worth, and please note I was not successful at following the 
above advice myself. My kids got “exposed” to a bunch of this, never really 
clicked on it, and only now (away in college) are beginning to get interested. 
They are sailing through their CS courses because they keep tripping across 
nuggets that they immediately “get” (having had me bore them to tears about it 
in past ages) while their classmates struggle - but that’s not the goal you 
were looking for.

Good luck!

Those first two titles sound reasonable.  The third sounds strangely

I would not put it that way.  "Brilliant" is a term of praise, as is 
"visionary".

Someone who claims that "nobody programs in assembly language any more nor will 
ever again" does not merit those adjectives.  The correct adjectives would be 
"ignorant" and "myopic".  Those are the correct terms because their assertion 
is valid only if you limit yourself to a limited class of programmers, and 
ignore compiler writers, diagnostics programmers, BIOS engineers, bootloader 
programmers, or embedded systems developers, just to name a few.

I'm surprised that such people would be working at a supposedly highly regarded 
outfit like Berkeley.

[top posted, with Swift's remarks below]

The Clancy and Harvey topic is about curriculum, and teaching of "computer 
science".  Clancy and Harvey were/are two lecturers at UC Berkeley, who 
ended up in charge of lower division under-graduate CS.



First, I'll explain OUR curriculum at the community college, since that is 
what I know.  We had a varied mix of re-entry of dropouts, job training, 
AA degrees, preparation for transfer to 4 year colleges, skills 
enhancement for people employed in related jobs ("I want to take a course 
in C"), and adult enrichment.


We started off with an extremely simple introductory course that did not 
assume that the student had ever seen a computer. (In 1980 or so, that was 
a necessary assumption).  Offered as a 6 week drive-by, but generally a 
full semester for those who intended to go further.  It had just enough 
programming in it that a student would successfully create a program. 
(often done with BASIC)


Then an Introduction To Programming, with basic principles and concepts. 
Illustrated with multiple languages, but concentrating on a language of 
the instructor's choice for some minor projects.


Then choices of courses in multiple languages: COBOL (2 semester levels), 
FORTRAN, BASIC, Pascal, RPG, C, Mainframe Assembly (360/370), 
Microcomputer Assembly (X86), and occasional ones for only a few years 
each including RPG, ADA, etc.  Not all classes offered every semester.

Also work skills classes in using Microsoft Office, etc.

Data Structures And Algorithms, with a prerequisite of at least one 
programming language, and taught in language of instructor's choice (I 
used C, but I let students substitute other languages).  When I taught it, 
I included iterative V recursive tree algorithms.


I also taught "Microcomputer Disk Operating Systems" (heavy on MS-DOS, but 
trying to actually teach the principles applicable to ANY), and "Advanced 
Microcomputer Programming" (prerequisite of C and Assembly) which included 
TSRs, device drivers, walking directory trees, mixed language programming 
and stackframe structure, etc.  One of the assignments was to write a 
program that would display a complete directory of the disk.  I taught 
with C, X86 ASM, and MS-DOS, but students were free to substitute 
other languages and unix, Mac, or whatever, for their assignments.


I tried to implement a basic information science course on access to 
online information resources, but our curriculum committee vetoed it and 
rewrote it into how to surf the web.
We had constant struggles with the administration, who wanted to, and 
eventually succeeded at, removal of all advanced courses and anything with 
a prerequisite.  They REALLY wanted our department to be nothing but 
remedial job training for the digital sweatshop.  They killed EVERYTHING 
that had been worthwhile!
By 2013, when I finally told them to take my 33 year job and shovel it, I 
had still been unable to get them to let me try to do a basic beginning 
Information Science course (DIK/W/E, relevance ranking, economics and 
legalities of IP, recall/precision interaction, social impact of access, 
search engine algorithms, SEO, etc.)




Anyway, back to, . . .
Clancy and Harvey reworked the UC undergraduate lower division (first two 
years) curriculum.  They setup a three course sequence at the core, 
consisting of "Abstraction", "Data Structures", and "Demystification". 
They called a meeting of local CS departments to tell us what we should 
switch over to teaching.


They chose Scheme (a LISP derivative) for the first course.  They thought 
that recursion should be the fundamental basis of computer programming, 
even down to COUNTING from 1 to 10.  I used to usually give an assignment 
of Fibonacci numbers as an exercise in loop controls, etc. - I was a 
little taken aback when somebody from UC thought that it meant that I was 
starting my students off with recursion!  They gave a small example, which 
they declared CAN NOT (not "must not") be done with anything except 
recursion.  While they were putting it on the board, I coded it on my 
notepad as a two dimensional array with a nested loop in C, BASIC, 
Fortran, and got partway through COBOL.  (I take offense at being told 
things are "impossible" to do in other languages - "difficult" or 
"inappropriate" are acceptable).


Their "Data Structures" class was to be taught using C.  I asked about 
their C class.  They didn't have one, and declared that all students are 
assumed to already know C before they arrived there!


Their "Demystification" would be the first time that the students would be 
made aware of existence of anything under the hood.


They declared, "Nobody programs in Assembly language any more, nor ever 
will again."


I asked about timeline for implementation

Most of the Usborne books from the 80s are available on Usborne's web
site as PDFs -- "Simple BASIC" (for younger readers) or "Introduction to
Computer Programming" (for slightly older readers) might fit the bill:

Re: Need Rec: Book to teach about computers and BASIC at an eight year old level

I can suggest "Instant BASIC: Freeze-dried Computer Programming: Jerald R.
Brown" as a good kids entry-level text. Like numerous other 1980s era DIY
computer books, it's probably available for free download from archive.org.
I also have a spare copy.

And BASIC is great, but as soon as the kid grasps the concepts, move him to
Perl or Python ASAP. Basic -> Perl is very easy, heck you can even use line
numbers if you want.. and it's a far more useful language in the modern
environment.

Front Panel News - New production run coming up


Hi

   Our order for front panel blanks has now arrived. We have enough 
to make ten of each of


PDP-8/e (A)

PDP-8/e(B)

PDP-8/f

PDP-8/i *

PDP-8/L *

PDP-8/m

* New - uses a 465mm x 150 mm panel

I'm expecting production of  PDP-8/e (A) and PDP-8/e(B) to start on 
Tuesday 31-MAY-2016 at one layer per day (allowing for drying time) plus 
set up and packing. The first panels should start coming off the line on 
or about 8-JUN-2016.


PDP-8/f and PDP-8/m should start about the 13-JUN-2016  finishing about 
22-JUN-2016


Followed by PDP-8/i

Followed by PDP-8/L

Followed by PDP-II/XX

Price remains unchanged at USD150.00 per panel plus USD20 shipping.

Payment to PayPal  rodsmallwoo...@btinternet.com

There's only ten of each type so one of each type per customer please

Back orders ship first then in order received sequence.


_*Just a quick note about production techniques. *_

The printing is done by hand on a printing table. Its a big heavy cast 
iron tray about a foot deep and five feet square. It stands about three 
feet high  There are hundreds of small holes in the bottom to allow a 
vacuum to hold down whats being printed.  On top of the table is an 
arrangement of bars and slides to allow one or more silk screen frames 
to brought down on a work piece held down by the vacuum.


Next to the table is the drying rack. It looks like half a giant 
rolodex. You put your wet work between the pages.They are made of open 
mesh panels to allow air to circulate.


You  start by marking the position of the blank panel on the bottom of 
the table. Then the first screen is positioned over the work and 
horizontal movement locked. You can still move the frame vertically.


Position your work between the marked guides on the bottom of the table. 
Bring down the frame and drag the ink across the screen. Put the wet 
printed blank in the drying frame and repeat for each panel in the batch.


Wait 24 hours and setup your next fame for the next layer(color) Take 
first panel out of drying rack print and replace.


Repeat for each board in the batch until done. Cycle time per batch 
about eight days elapsed.

Series/1 used  either EDX  ( Event Driven Executive) or RPS (Realtime 
Programming Systems)
Could be programmed in a variety of languages. I think I used COBOL on EDX. 
The app was a Transaction -processing Newspaper Classified Order Entry system 
supporting 300 seats. 
The project started in 1976  well before PC's were around.  
The architecture was Zentec programmable 8080 based Terminal for the user 
interface, data sent to Series/1 via BI-SYNC protocol, then forwarded to IBM 
3032.
I did the programming for the Zentec. It was fun! It had no operating system at 
all.   Just 8080 interupts. Basically you wrote assembly language to grab the 
character from the kb interupt and figure out what to do with it.  (like store 
the character on the screen, move the cursor left (or right if delete char) ) 
and a bunch of other stuff.

As far as I know Computers have been managing missiles for a long time now.
I can see issues dating back a long time reported here:-

I remember I was on a Honeywell course, must have been around 1980, when one
of these happened. 
The performance of the machine we were using on the course was somewhat less

long time.

We joked that if the WWMCCS

I was at IBM from 1979 through 1997.  Started in Boca Raton and
finished up in Austin.

There was a lot of politics going on the entire time I was there.  One of the
reasons that I left was that the project that I helped start (and worked on for
5+ years) was cancelled because a director got himself into trouble with OS/2
(when was it *not* in trouble) and decided that the folks who were working on
the project I was on (who were considered the “stars” of the division) would be
better applied to OS/2 (we cancelled SW that customers had already paid for).
I don’t think any of us who were “drafted” into OS/2 stayed more than a year
after that.

Yes, a remarkably few number of modules make up a huge bulk of the
population. Of course there are some rare types, like the high speed
versions or the ones that IBM farmed out, but they can mostly be
ignored.

Yes, those are the things that are really pretty common.

I suppose chip level repair might be possible with today's SOTs, but I

I can appreciate some of the elements, also. It's just irritating when
they start turning it into meeting (oh wait... scrumm) hell and folks are
more focused on pushing the methodology than completing the project.
I had the task of doing mouse firmware for a project that ws a huge 40 
person C++ object oriented mass of crap with all the stuff that goes 
with that.

Note Customer here means the entity that consumes or engages your end 
product.  In this case there were other bits involved that were also 
large blank page projects, since this was an aircraft product. The 
hardware, manufacturing, test program, and even business and marketing 
were all formal, with little of the bullshit you'd think of as random 
operations in especially marketing and sales.

But in my tiny corner they were all blockheads about what I had to do to 
be "agile" and I just basically said go f yourselves.  I was basically 
expanding a manufacturer supplied sample code set, and I always work 
iteratively, but a lot of the things I had to do had to respond to 
things that were not planned.

The model of formally planning out the stuff that Agile has sometimes 
doesn't work.  Especially in places where embedded programming is 
involved.  But if the managers would look at what you have to do, 
frequently it is a modified version of that.

In this case the manager had never touched low level programming which 
was part hardware and software ever, and didn't get how much had to be 
"tried" and modified.  Luckily there were people who got the problem and 
eventually it was a good project.

That sounds very much like IBM.  I was there for @ four years (from 2000

You ask the community. You ask on the list or elsewhere. "Hey, I need

But in those six or seven years - wow, did they make a lot of them. In
Binghamton, we have some of those dumb desk ornament things that suits

(OK, we know that being a dumb desk ornament, they probably made some

the desk ornament is dated fairly early in the game!

SLT and S/360s did indeed have teething problems. It took a while to
get the bugs out of the system.

IBM SLT cards and modules seem to do well - I have picked up more than
a few that were exposed to the elements, and if they are not beaten up
(curse those crappy thin aluminum covers they used!), moisture tends
to not be a big issue, thanks to the silicone goop underneath.
