For my first PC/XT clone computer, I built my own case. I put the?floppies and power switch on the front and all of the ports on the side (the expansion cards ran from side-to side rather than front-to-back). Much easier to get to the cords that way and there were no wir es sticking out the front.

Some of you will find this amusing, anyway. This is a verbatim quote
>from our *current* graduate CS handbook:
The department?s computing facilities include Sun and Silicon Graphics
workstations, SGI Crimson and SPARC servers, and high performance
graphics workstations (SGI Indigo2, Onyx Reality Engine2). The Office
of Information Technology has over 400 workstations for general student
use and several high-end machines including a Silicon Graphics Challenge
XL 20 processor system. UMBC?s Imaging Research Center also provides
high-end graphics support including production quality input/output
devices and production software (Wavefront, Softimage, and Alias).
While these are cool machines, I did see some of them at VCF East this
past weekend. I'm pretty sure the school doesn't have them anymore. I
guess weeding out old info isn't a top priority. :-)

Does anyone have one of these animals? I am trying to reproduce an old
video game that was based on it and figured it might be easier with the
Eval. board.

Guys,
Does anyone recognise this transistor module, presumably from a 60s computer?
Many thanks,

I have copies of the SCO manauls available. About 40 pounds worth of OS
and development system stuff. This is all pre-OpenServer stuff. It is
SCO UNIX 3.2v4.0
They are located in Wantage NJ. Come and get them or pay me to ship
them.
If anyone is iterested let me know, or they go the the recyclers.

The RICM has the processor of their PDP-8/I functional after replacing
or repairing 38 Flipchip modules and the core stack. We have lots of
Dectapes that originally held data from a PDP-11, but nothing that is
bootable on the 8/I. We tried the TC01 bootstrap with one of the
PDP-11 tapes. It moves the tape to the first block and then gets a TIM
(Timing Error), so the TC01 and the TU55 is at least partially alive.
Can anyone supply a Dectape that would be bootable on this 4k machine,
or tell us the procedure for making a bootable Dectape?

although without any pointers or links. I have the U/S IIIi User's Manual

No reward except my gratitude and promise to search my archives for my pals
in need! However Al is making it pretty tough to have anything unique! Many
thanks to Al for running bitsavers and everybody for contributing.
I hope archive.org sticks around long enough for us to scrounge whatever is
left on Sun but it's getting thin. I haven't been able to get to the open
firmware site on playground.sun.com and the official site is running a
business on openfirmware and isn't exactly giving out doc. So much for open.
Thank you.

Consider the computer in front of me. There is a keyboard, a mouse, a trackball, and a Wacom Inkling all plugged in and active using USB. How do you do that with only two ports?
I use the trackball and occasionally the tablet. Another user uses the mouse and the tablet. All without unplugging and plugging the various devices...
