I recently got a few parts together to build a 486 computer to mess around with OS/2 warp 3 and a few other old OS's.
Now that I got the system together I find the motherboard is dead, my other boards are PCI so I cant use them.
Anybody have an old 486 socket 3 motherboard they dont need? Has to have at least 2 VLB slots and no pci slots. Boards with 72 pin memory slots would be nice but not necessary since I have 30 pin simms around here. I will need a processor also if I cant use my AMD 486/120 or 486/133 on it. The board I have has a 486/66 but I am not sure if its dead or not.
The reason I want VLB is to use my promise IDE caching controller and the Diamond stealth 64 VRAM (with expansion memory board) VLB cards which were pretty fast in their day, that and I dont have an old world VESA machine to mess with.
If you have a board let me know and we can work something out.

I had guessed at it being a security card of some kind. I had found that
google hit, which is why I made that assumption.
You however are the first source I have found that can seem to confirm
that fact.
Any idea what it was used for, or was it like many security dongles, a
company bought them and included the checking code in their software, so
it could be for just about anything.

As some of you may remember, back in August I started having problems
with my PDP-11/83.
First, the breaker would trip at odd intervals. I moved all the boards
to another box and found that I started getting clock errors. Today,
after many months of being too busy to do any thing more, I took the
power supply from the 2nd box and installed it in the original 11/83
box. After moving all the cards back over and re-connecting all the
cables I finally got the system to boot, no errors! Yay!
On another note, I should have the PDP-11/73 that sits in a desk within
my cube at work up and going soon. The RD-54 arrived yesterday, and I
should be receiving a TK-50 within the next couple of days. After that,
I'll put BSD2.11 on the drive and place the thing on the net.

Hello,
I saw your MDS-800 systems. I too have some of this stuff. I am trying to
hook up a terminal to my 800 but having no luck. I have no docs. Do you know
what connector & its pinout, baud rate, etc. to connect RS-232 to?
Thanks,
Ray
I picked up my 11/45 in TN today, and bought the trailer it was on as well.
Just finished pulling it into the garage. Fortunately, it is very well
packed in cardboard and shipping blankets and tiedowns. However,
unfortunately, my car can't make the curb to get it around the back. So I
have to wait till tomorrow, when a friend comes over with a truck with a
hitch. Then after it's moved to the basement I'll be able to pull the cpu
drawer out and find out just what kind of cpu is in it, what kind of (and
how much) memory, etc. Yay! I'm excited :)

Jay,
I have the 1976-77 PDP11 04/34/45/55 processor handbook and
the 1978/79 PDP11 04/34/45/55/60 processor handbook originals. If you
don't find one to keep, you may certainly borrow one or both. Ah hell,
you can keep them, I'll never put one of those systems together and they
have been looking for a good home. Send me an address to mail them to.
regards,
Joe Heck
