Fwd: [TUHS] Recovered!!! The Georgia Tech Software Tools Subystem for Prime Computers

2019-09-27 Thread Al Kossow via cctalk



Have been on the road, and I just noticed this announcement on the TUHS 
list.

I'd been trying to find this for a long time


 Forwarded Message 
Subject: 	[TUHS] Recovered!!! The Georgia Tech Software Tools Subystem 
for Prime Computers

Date:   Tue, 24 Sep 2019 22:45:29 +0300
From:   Arnold Robbins 
To: t...@tuhs.org



Hello All.

Believed lost in the mists of time for over 30 years, the Georgia Tech
Software Tools Subsystem for Prime Computers, along with the Georgia Tech
C Compiler for Prime Computers, have been recovered!

The source code and documentation (and binary files) are available in a
Github repo: https://github.com/arnoldrobbins/gt-swt.

The README.md there provides some brief history and credits with respect
to the recovery, and w.r.t. the subsystem and C compilers themselves.

Credit to Scott Lee for making and keeping the tapes and driving the
recovery process, and to Dennis Boone and yours truly for contributing
financially. I set up the repo.

For anyone who used and/or contributed to this software, we hope you'll
enjoy this trip down memory lane.

Feel free to forward this note to interested parties.

Enjoy,

Arnold Robbins
(On behalf of the swt recovery team. :-)

A fun patent to wrap your head around

5287534 "Correcting Crossover Distortion Produced When Analog Signal Thresholds

It describes the DEC CXM04 board for the DS550 communications server, which 
inserts itself between an IBM establishment
controller and a control unit (coax) terminal so the CUT can pretend it's a 
serial terminal to VAXen without dropping
the polled connection to the IBM mainframe.

Do all three busses share the same ground pins?
Many proto boards I've seen have ground planes on the board backside.

Other suggestions I've seen are beefing up the trace widths (esp for the power 
pins) and
changing the pin spacing to be able to use a .1" header for the edge connector 
pins.

Anyone have a mid-80s Robinson-Nugent connector catalog?

2019-08-13 Thread Al Kossow via cctalk
Or some RN 68 pin CLCC sockets, or even a part number for them?
I tried buying a 1981 RFN catalog, but they weren't in there.

I have a bunch of IMS 80186 slave cards with the CPUs pulled
Of course, they didn't keep the caps. RN was bought by 3M and
I've been unable to even find a part number for these sockets.
I'm hoping not to have to replace the sockets to get these boards
working.

We don't have one in working condition, and we're unlikely to attempt any work

recovery any time soon.

I have three Pertec top-loading drives and several Diablo 30s, but haven't had

Anyone have an Ethernet interface card for an AT 730 terminal?

2019-06-29 Thread Al Kossow via cctalk
I just finished taking pictures and dumping the firmware from a 730X terminal
but it turns out it has a Starlan and not an Ethernet interface. It would be
nice to get a firmware dump from an Ethernet card. A start of a 630 driver is
in MAME.

http://bitsavers.org/pdf/att/730/730X

It also appears the keyboards for the 630 and 730 aren't backwards compatible
with the other 6xx products and the 5620. 5620 keyboards need -12v which the 
630 or 730
don't supply, and the 610 keyboard doesn't appear to work either. Josh took a 
couple
of pictures of his 630 keyboard and even though they look similar, the earlier 
keyboards
were made by Teletype and the 630 is made by Keytronic.

with the switch to 800bpi (coercivity change with the darker
formula)?

it is the top half of the 10.5" CPU chassis

the tape controller is probably internal to the cpu and with have three ribbon 
cables going from the
drive to the controller (read,write and control)

there should be a 26 and 60 pin ribbon cable going to the smd drive from the SI 
and a unibus cable from the
SI to the CPU

FWIW, IBM auto-load hard plastic seems to be holding up better, you might be 
able to find a small
quantity of those around.

Failing that, late era crappy tape might be found, and the seals scavenged 
though the price is
probably prohibative.

It is a DS1287
The issue is finding out what the contents should be, since it isn't
documented in the surviving manuals.

Some of this was figured out in getting the 2030 to run in MAME and there
is a guess at the correct contents as a rom image there.

If you have the original timekeeper part, the unique part of the
machine's ethernet address is written on a label on top of the part.

You might be able to take the fake nvram data from the simulation in MAME

I'm about to try that this week since I got in the NVRAM and video cable.

correct.

I see the illuminator, but I don't see the eyepiece you use for surface 
inspection
in there. There should be a black tube with a lens and a right-angle mirror.
