[cctalk] Re: Antonio's call for donations (was LCM auction)

[Doug Jackson via cctalk]

I never thought I would write this, but can we please keep drug induced
Scandemic theories off list.

I would have thought that as a group of technical people we would all have
been capable of thought and could read.

There was a pandemic.  There were vaccines of varying levels of success
developed insanely quickly.  They were succesfull in slowing down
hospitalisation rates, which was all they needed to do.

Humanity is better for them.

If you disagree, please turn your computers over to another list member,
put on a tin hat, and go somewhere else.

By the way, the earth is round...

Sigh...

[cctalk] Re: DOS p-System Pascal: (Was: Saga of CP/M)

[Doug Jackson via cctalk]

Circa 1986 I was working at the Research School of Physical Sciences at the
Australian National University.

As late as that we were still running CP/M on an eclictic mix of Imsai8080
and STD Bus based machines.  These were all running laboratory
experiments.

Turbo Pascal was king in that environment.  C compilers were just way too
weird to even consider.  Even when we started rilling out IBM PC's in about
1988, we still used Turbo Pascal.  Re compiling apps for the new platform
was magic...

When I left there and moved into a small packet switching hardware
developed in the mid 90s, we used Turbo pascal for the PC side of any
interface, and Cross compiled C for the 68000/010/020 based hardware plug
in line controllers.  Everything was hosted in a custom VME rack system
running Unix.

C didn't enter my world until I started running FreeBSD in the late 90's
where it was essentially part of the OS.  I remember paying $600 bucks AUD
for a Borland C compiler running under Windows, but the whole concept of
writing a simple app was insane.

Now I use C and C++ regularly for small microcomputers, but still not on my
CP/M systems.

[cctalk] Re: Turbo Pascal Kermit for CP/M

[Doug Jackson via cctalk]

Wow,

I agree that there is clearly an incompatibility - I wonder how?  CP/M
should be CP/M...  Just the BDOS changed for the individual machine
hardware.

One thought is the screen RAM may be an issue with overlaying.

I suspect that Borland didn't notice, as the TRS80 Model 4 was really late
in the 8 bit world, having been released in 1983.  The IBM PC was released
in 1981, so I suspect that by the time somebody ran CP/M on a Model 4,
Borland had moved onto PC/MS-DOS.

Hi Kevin,

Often that is because you signed up using an old email that is forwarded to

Hi Stephen,

Sorry to use your Fig Forth thread - I too have a Corsham 6809 system, with

If you had success down the Fig route that would also be great - but do you

Hi Everybody.

It is important to keep everyone aware of phishing attempts, but it's also

[cctalk] Re: Store with "vintage" computers and parts

[Doug Jackson via cctalk]

At this point I will chime in.

I brought what looked like an Imsai keyboard from this crowd, or a previous
version of them - The web site is *amazingly* similar.

The keyboards were cheap as chips,  $149, so I went for it, knowing that I
was protected by PayPal.

I get tracking details pretty quickly, set as awaiting shipment, I also got
a weird - non professional email saying that they had sent the item.

After a week, still no movement on the tracking item - I queried them and
got yet another number.  Still awaiting shipment.

Another couple of weeks - no movement, no keyboard delivered, and no
response from their customer service, so I contacted Paypal and raised a
case.  At this point, I am screenshotting everything for evidence.

Paypal was great - they contacted the seller, who said that the item was
shipped.   Another new tracking number.

After another couple of weeks,  I contacted Paypal again - they contacted
the shop - the shop provided 'evidence' that the item had been delivered to
Sydney (350km away) - Paypal asked me if I had it - I live in Canberra, and
of course I hadn't got it.

They clearly went to the trouble of trawling through USPS tracking details
to find something that was shipped from near their suburb to Sydney
Australia by somebody else and submitted it as their evidence they had
shipped.

I went ballistic with paypal, and got a refund.

100% would not recommend.

Friends,

The process of migrating the cctalk and cctech mailing lists to a new host in
Chicago is underway.  This evening, I've moved the list mail handling to
the new server, and this message will be the first live test.  Assuming
this works, you shouldn't have to change anything to post to the list.

The green web pages, the old "pipermail" list archives, and web access to
archives of new postings from this point still require a little work, which
I hope to complete in the next day or two.  I will eventually import the
old pipermail archives into the new posting archive, but that may take a
little longer.

The new hosting is provided by the Chicago Classic Computing group.

Many thanks to Jay West for hosting the lists for 20 years!

[Doug Jackson via cctalk]

Off topic - but interesting.

I had a very frustrating experience with an 80188 made by Innovasic.

The SBC188 BIOS would halt if the chip was used because its power on
behaviour was different to the Intel 80188.

I agree that we should probably use the intent of a specific era.

I believe that the world certainly dropped out of my personal definition of
'Classic' when the 386 came in.

I have an interest in things up to and including 80186, and they certainly
are not run of the mill.

Just my thoughts.

[cctalk] Re: Bubble Memory

[Doug Jackson via cctalk]

It is disappointing that you have encountered people like that.

My most recent purchase was a couple of potentiometers for a Kenwood TS440
radio - made from true Unobtanium.

from memory, I paid $100 USD for the auction and $70 USD for the shipping.
They shipped through the Ebay global shipping system which is a rip off,
but the people who filled in the forms were the global shipping people.
The sellers experience was that they simply sent the package to an address
in the states.

My experience was that I got the item I was happy to pay for.  I didn't
complain about the shipping, because some people understand that sending
stuff costs money..

The alternative that I use is a US on-shipping firm MyUSA.com, but I try
not to use them anymore, as they had a meltdown because they thought I was
trying to get them to onship an ITAR controlled item (A satellite
antenna).  They couldn't read the government's own doco, where part number
xxx-xxx-xxx-xxx-01 was ITAR, while xxx-xxx-xxx-xxx-02 was not ITAR
controlled.  In that case, I got them to ship it back to the seller, who
onshipped it (again at my expense) to a friend, who shipped it for me.

My comment was simply based on my experience, as a purchaser who is quite
happy to pay through the nose, because I understand that a plane flight to
the States costs much more than anybodies shipping.

We can synthesise those with a Female edge connector and a nice Gold Plated

Re: That VAXStation4000vlc 3W3 video connector

[Doug Jackson via cctalk]

HI Paul,

"I don't know what "HD BNC" means.  There's only one BNC"

Years ago when working in a university with Photomultiplier tubes, we used
HV BNC connectors - these looked like standard BNC, but were rated at 10kv.

https://www.radiall.com/products/rf-coaxial-connectors/high-voltage-connectors/bnc-ht-mhv.html

We also used to use 75 Ohm BNC connectors for video systems.

https://www.hubersuhner.com/en/products/radio-frequency/connectors-adapters/bayonet-connectors-bnc/bnc-75-real

It is worth noting that there are multiple BNC connectors.

Re: evil thing to ask but I need keystroke logger

[Doug Jackson via cctalk]

Have you considered asking them what they are doing?

You would be surprised how much logging various software packages do.
There are always chat logs (unless deleted) - always usage logs - unless
deleted.

Work with them as a first instance, failing that have them do the work
physically beside you.

Most traffic coming out of PCs these days is SSL encrypted, and you are not
likely to extract meaningful data from a session.

Re: R65F11

[Doug Jackson via cctalk]

WOW!!

I Have one of those ETI boards, and I based my final Electronics
Engineering project on its big brother, the 65F12.

>From memory, I spent days trying to understand why you had to issue a HEX
1800 MEMTOP command before using the disk.  ETI Suggested that it was
because the system had to know where the top of memory was, but it was
because of a bug in that version of the kernel.

The 65F11 had all of the headless primitive in kernel rom, and used a
development ROM that contained the higher level words.   I Loved the
concept, but the silicon was expensive and as it turned out, rara.  Nobody
knows anything about these chips.

At Uni, we hav Novix NC4016 dev boards with FDD support - they were FAST...
One cycle could see the CPU read the next instruction, write a byte to the
stack, and write a byte to I/O - all because it used three (or 4) separate
busses.

I'm here in Australia, and would merrily give it a home. :-)

Re: AW: CGA card (Mitsubishi Electric) with 192K RAM?

[Doug Jackson via cctalk]

I recall some of the high end cards in the CGA / EGA era had adon boards
that were connected with a 20 or 36 pin jumper cable across the top of the
boards - They also ran more than 64K or ram, such as the ATI Wonder
boards.  Maybe it's like that - the ATI boards had 256K so they could page.

Re: Spam

[Doug Jackson via cctalk]

Not me either,

But I pass all of my email through gmail, and it filters out all of the
spam for me anyway.

A couple of years ago, some helpful person selected my email for sending
millions of messages and it broke my email environment, the only way I
could get it working again was to either abandon my email, or use gmail for
everything.

instant, clean email feed.

Re: Comp.lang.forth: banned on google groups?

[Doug Jackson via cctalk]

Comp.lang.forth taught me that flame wars were fun and all I needed to
enjoy them was popcorn.

It also showed me how every person writing their own version of a language
and the associated flame wars actually damaged the the community.  I
suspect much of Forths lack of traction can be attributed to that.

Are you sure it's really useful historical material?

Re: Adventures online

[Doug Jackson via cctalk]

Sadly, the original tweet doesn't mention what mainframe - Somebody did
ask, and there was no response I could see.

The error messages suggest it's some sort of Linux system using Docker
containers, so it's not OS/360 :-)

I suspect given that it's running out of memory, that it's yet another
linux box.

Re: Ancient transistor ?computer board (Peter Van Peborgh)

Hi Peter,

That is a stunning board, and in beautiful condition.

The square cubes are transformers, most likely some sort of pulse
transformer on the base of the transistor.

A multimeter will tell you in quick form.

Re: Future of cctalk/cctech

[Doug Jackson via cctalk]

I gave up on hosting my own email years ago when I was the recipient of
tens of thousands of spam messages per day, both to this and my business
email address.  I now simply use gmail to handle email - seems like the G
beast has seen every bit of spam before, so the spam transfer rate is
approximating zero.

All of the old mailing lists I use are on groups.io -   I actually don't
log into their platform, instead they send me updates as messages.  These
often contain attachments, which don't bother me, as its using google mail
storage to store, and unless its interesting, I don't bother copying it
into my world.  That way, complete disk images can be sent and I don't mind.

Using a glass screen VDU with a mouse, means that the sparse, and expensive
to obtain paper for the TTY is not adversely used when somebody top or
bottom or sideways posts.   And I can even catch up on email while I am
using my phone in the bus.

If we do implement attachments that are limited to one SSDD 8" disk, can
there please be some technological way of chaining disk 'parts' to allow
larger attachments to be transmitted?

Re: Ancient transistor ?computer board

Ah... I suspect it's an example of modern web apps being excessive.

That URL was likely only active during the session that the user was active
within.  When the session went away so did the URL.

It's longer than the information content of the universe to stop it from
being accessed by somebody else intentionally during a session by brute
force.

I love the modern internet.  It's apollo obfuscated.

Pdp11/05 boot media

[Doug Jackson via cctalk]

Hi everybody

I'm the proud owner of a PDP11/05 system with a couple of 8" floppy
drives.  I believe they are likely to be RX01s.

Does anybody on the list have some boot media that they could provide.  I
understand that the controller can't format the disks so I'm in a
frustrating state where I don't know where to start.

Re: HP 41-CX

[Doug Jackson via cctalk]

Hi David,

That certainly is a shame.  For the gold plated contact to corrode so badly
means large amounts of potential damage to the flexible PCB.

You may be able to repair it using some brass shim - but I cant see how
else to repair it.

The CX was a wonderful machine - and seeing this has reminded me of many a
night at uni.

Re: OT: Weller soldering irons

[Doug Jackson via cctalk]

for me, the item that usually fails in the WTCP series is the switch at the
end of the sensor.

I have replaced the sensors each time, because dammit - My 40 year old iron
sometimes just needs a new cord, or a new heater, or a new tip, or a new
sensor.  Best iron I have ever had :-)

Re: pdp11/05 key?

[Doug Jackson via cctalk]

I'm literally in the process of starting this.

I have a pdp11/05 and the key was snapped off.  I brazed it back together.

The barrel is a three wafer unit.  It is easily removable by undoing the 4
screws to remove the front panel.  Removing the screws holding the micro
switches in place and removing the lock retaining plate.

I was going to take the key and barrel to a local locksmith for him to make
some spares.

Re: SWTPC SuperClock II board

That's a beautiful board.

While I have no docs, a careful look confirms for me that it would
superimpose something (likely clock data) on a video signal.  The

Re: HPE OpenVMS Hobbyist license program is closing

So.

At the end of the day there are three paths.

1.  Accept that HP doesn't give two hoots about hobbyists and patch the
abandoned operating system to fix the problem.

2. Declare that we need to develop an open replacement.

Or

3.  Accept that HP actually owns the rights to our VAX 11/785 machines and
arrange for them to be dropped off at their corporate headquarters because
they can't do anything without software.

Sigh...

Re: Nuke Redmond!

[Doug Jackson via cctalk]

It is.

He ended up serving 15 months in prison for making rescue disks that were
based on downloadable software that required licence keys that the PCs that
he refurbished already had.

It's a complex.case and the judge didn't understand the actual value of the
media which was zero.

Sadly technically he did breach copyright.

So lesson to learn.

Stay away from software giants who have bigger bankrolls than you do.

computing industry standard and boring.

Anything pre - 1982 is interesting, anything post 1982 is a boat anchor...

Re: Password reset for ~1998 AIX on RS/6000?

[Doug Jackson via cctalk]

Hi...

>From memory there were a number of remote exploits against AIX 4.x.x

The most simple were against ftpd.

A quick search found this..

https://www.exploit-db.com/exploits/14409/.   This extracts the root user
hash.


Of course if you have local access there is the rlogin vulnerability
against some versions that allowed a normal user to have root privileges
with a trivial command line such as rlogin -l.  But my memory is foggy
there.

Should be a fun task.  One of the nice things about old operating systems
is that there security is pretty well non existent as.things that were zero
days in the 90s are well known now.

Re: Preventing VAX running VMS / Multinet from being used as SMTP relay

[Doug Jackson via cctalk]

Camiel,

Without sounding super negative (my day job as a security consultant let's
me do that  enough...)  I would be especially wary of connecting anything
with a 10 year old stack to the modern internet.  The range of automatic
attacks based on what the state of the OS was when it was last patched is
staggering.

Can you NAT it behind something to not expose it directly?   Can you run
proxies in front of it?
