Aw, come on, you could know it better. We also have a 704 since many
years, including software and documentation. You have mirrored my scans
on bitsavers ;-)

Nicolet 1080 is 20 bit data but has 16 bit address space. No stack functions.
It has a register called link but that is only a single bit carry. Subroutines
use the first address to store the return, meaning they were not recursive
without something to save the returns ( I think dec did this too
I'm interested in looking at any published drafts prior to the C 1989
standard. I found X3J11-88-090 here:

I have some kind of IBM 3270 MCA board available for the cost of shipping
from Sweden. IBM P/N 26F0191. Have no way of testing it, but it was pulled
from an otherwise working machine.

I have what I believe is an unused RA60 head #4. At least the surface looks
very clean.
Someone has written "RA60 04" on the side of the box. On the top there is
handwritten 70-18661-04.

I could use a RL02 or RL01 head as a trade if someone is interested.

Hi Gerard,
Yes, it's been there for some time. Al K. uploaded it upon my request.
It turns out that my guesses about the architecture based on floppy disk
data were correct!
Thanks,

@ Chuck,
I know you know about the FST1 computer ( 24 bit ).
Do you know that there is ( now ?? ) a bit of documentation about it on
Bytesavers ??

Anybody interested in a pair of Tseng Labs ULTRARAM boards?
I assume they were expansions for the Tseng Labs Video Cards
but, if nothing else, they are loading with 4164's.

Those are for Tsengs Labs Ultrapak monochrome ISA video cards I think.

I have no idea. They are just stuff I collected over the
years working at a University. I was never impressed
by Tseng Labs but, like I said, the boards do have a
bunch of 6146's on them. Lot's of old systems used them.

A friend of mine passed away a few days ago, and I am helping his brother

Hello Paul, I would be willing to take on the task of converting all the
