Sorry, I didn't mean to upset your plan (and you); I just didn't know if
anyone was watching for VAX-11/780 parts, they come by so rarely.

We have discussed this topic before, but let me recapitulate one point about
pricing and valuations: if we want to stop this stuff being scrapped, we need
to make sure the prices realized are well above scrap. This will have several
consequences:

i) If people only get low (scrap-region) prices, why go to all the
bother/hassle of listing things on auction sites; just proceeed directly to
'Go'. ii) Hopefully, if values are non-trivial, the word will get around, and
people who have this stuff will go to the effort to list it, instead of
leaving it to moulder, etc.

Yes, I understand that will make this a more expensive hobby, but TANSTAAFL.
YMMV.

RE: IO Selectric

[Dave Wade]

Thanks Chuck,

 I should have got those before as I have been a member on there for ages,
just couldn't remember they were there. The stuff in mine looks very similar
to the Louis Sanders article I have, so I am sure its from the same article.

 I now need to read the theory and clean, adjust and lubricate.

LASM compatible cross assembler?

[Chris Osborn]

After getting my TRS-80 Model II keyboard repaired and up & running last week 
(http://www.insentricity.com/a.cl/257), I've been messing around with the 
Kermit source code to see if I can add hardware flow control support. I'm able 
to build Kermit using LASM on CP/M or on an emulator, but it would be nice to 
be able to setup a Makefile so I can do the build directly on Linux.

Is there a LASM compatible assembler out there with source available that I can 
run on Linux? I've tried a whole lot of different ones that are capable of 
doing 8080 & Z80 assembly, but not one understands the syntax of LASM (or I'm 
just not running them with the right flags).

I've tried so far:

  z80asm - http://savannah.nongnu.org/projects/z80asm
  as - http://john.ccac.rwth-aachen.de:8000/as/index.html
  kio's zasm - http://k1.spdns.de/Develop/Projects/zasm/Distributions/
  zasm - http://lpg.ticalc.org/prj_zasm/
  z80-asm - http://wwwhomes.uni-bielefeld.de/achim/z80-asm.html
  z80pack - http://www.autometer.de/unix4fun/z80pack/

Alternately, is the source code for Ward Christensen's LASM available anywhere? 
The best I could find was a note from a Kermit developer from 27 years ago 
asking for the source. I suppose I could use a disassembler, but then I don't 
have proper labels or comments.

Just for completeness and for future searchers who may run across my original 
message, I *was* able to get the typewriter open and get it fixed. After 
removing the two screws near the platen that hold the top on, you just have to 
pry the top up really hard. It's held in by two large metal posts in very 
strong clips.

The fix for the typewriter was actually very easy, it was just a blown fuse. 
I've now got it working with the Messenger Module and I'm able to print to it 
with both RS232 and parallel connections. I've also documented what I've been 
able to find about the escape codes for formatting and the dip switch settings 
on my blog:

  http://www.insentricity.com/a.cl/258

I'm disappointed that typing on the keyboard doesn't send anything out the 
RS232 port, but that was expected. But the typewriter works now and it's pretty 
cool watching it automatically type under computer control!

Many thanks for putting the patches up, Seth. My OS/MP Solbourne thanks you.

Re: SunOS 4

[Chris Hanson]

This all makes me want to try bringing up a modern compiler on SunOS 4.1.4 on 
my SPARCstation 20 again.

The closest I got was bringing up GCC 2.95.3 using the system compiler, I 
couldn’t manage to build GCC 3.3 or 4.2.1 for SunOS. (For legal reasons I can’t 
really go near GPLv3 developer tools.)

Maybe it’s a bit too much of a lost cause, and I should stick to Solaris 8. 
That’d let me install the upgraded CPUs too. And I could probably build 
LLVM/clang on Linux as sparcv8/sun4m cross-compiler much more easily too...

Last time I tried was around gcc v4.7 and it failed miserably with a bunch 
of linker errors. I have Sun's compiler on there, but it's not even C99 
compliant and that pisses off gcc something fierce these days. So, one 
would probably have to built it up stepwise, and maybe grab GNU binutils 
and see if their linker has any better luck. I ran out of steam and didn't 
try to go that far.

I'm going to start that with my 780 soon. I'll probably snag the eBay
parts if the price stays reasonable and I'll let you know how things
go.

BTW you mentioned you had had problems with your 730 main breaker too?
How exactly was it misbehaving? Did it sometimes refuse to power
machine even when it was in the ON position?

Using the simh LGP-30 emulator

[Oscar Vermeulen]

Some time ago, there were two posts asking how to operate the simh LGP-30 
emulator. It is not exactly obvious from the rudimentary manual, and it seems 
nobody had figured it out completely. I am slightly obsessed with this machine 
at the moment (it happens), so here is a how-to on operating the emulator and 
running the tape library of Christian Corti on it - in the hope it's of use to 
others looking for clues:


http://obsolescenceguaranteed.blogspot.ch/2016/06/using-simh-lgp-30-emulator.html


Corti's LGP-30 emulator, by the way, gives a much better feel for the machine. 
But simh source is available, which I needed because I'm making a replica 
hardware front panel for the machine.


Regards,

Oscar.

 You can surely get a proper Linux support contract -- proper as in: if 
you trigger a bug (which may be anything from a protocol violation, 
through a security hole, to a crash) in the kernel or other core 
component, then you can log it with your support provider's bug tracking 
system and get it fixed with an update release of the offending component 
provided within an agreed reasonable time frame, having live access to the 
bug status throughout the cycle.

 Now can you get it with Windows?  This is a serious question -- I've been 
asking various IT people about it many times over the years, and only got 
evasive answers (if any), but perhaps I asked the wrong people.

3511 seems to have been a thing from 1990 through 1993, according to IBM.

I googled up a brochure, and from the front it appears to be based on the same 
chassis as my PS/2 85. I guess it was meant to be an external SCSI enclosure 
for machines of that era? I believe that the 85 was intended for server duty, 
so a matching external drive enclosure makes sense to me.

My machine came without its original hard drive, so I substituted a SCSI2SD. I 
also added a SCSI CD-ROM drive that I harvested from one of my Sun Ultra 60 
stripped chassis, then used that to install OS/2 on it.

Yes, it was an external SCSI enclosure.  If I call correctly (my PS/2 memory is 
a bit foggy at the moment) it was roughly the same form factor has the PS/2 95 
(wider than the PS/2 60 & PS/80).  The 95 also had a pluggable processor card 
(with all of the memory on it) so it would be easier to upgrade CPUs/memory 
technologies.  The 95 also has a green LED character array (8 characters?) that 
information could be written to.  Had fun writing code to write stuff to it.

I wasn't trying to be critical at all. I just didn't make the connection that 
the auction was the specific announcement that you were referring to.

Neither did I, I was expecting a followup to the original email to explain what 
the announcement was. Or at least a message with “Announcement” in the subject.

Also, given my expectation of what those two machines would sell for and me not being in 
heavy acquisition mode at the moment, my brain subconsciously dumped that email into the 
"somebody else's news" category as a self-defense mechanism! :)

The road to hell is paved with good intentions.

Re: Attend and Participate Information Security and Cyber Forensics (INFOSEC2017)

[Curious Marc]

It's interesting. It's the new thing. I get spammed by these at work, maybe 
several a month now. It's more sophisticated than usual: they take the same 
name as legit conferences but with a very slight variation, copy or invent 
badges and affiliations, and are (supposedly) in unusual, remote, but 
attractive places. Web sites are well done at first glance, although it doesn't 
take long to figure they are slightly off in every respect, and always in the 
same format. Of course you need to pay to register, which will go straight to 
Joan who works for the famous organization @gmail.com. Jay can you take down 
the impostor please. 

And by the way, don't forget, I am organizing an IEEE Conference on Upside Down 
Pancakes in Peru in 2018. I haven't had the time to make the website yet but 
you can already send your money to me. I am not affiliated with Joan but my 
email ends with @gmail.com just the same, so you are in good hands.
