I had no idea, and I wro
ESDI used by CDC uses 150 ohms to +Vcc as termination on the control
cable. Signal cables are radial, so they always have termination.
See:

Also, generally, the CDC ESDI spec is here
Working on restoring this 11/83, I would like to replace the Fujitsu
2284E drive with a slightly larger capacity CDC/Imprimis WREN VI
94246-383 ESDI. I think I have the jumper configurations, however the
problem is the disk does not have a terminator pack.
Does anyone know what kind of resisto
If it's only got 18 pins (per the subject line) then I don't think it
can be a 27S29. Based on the label my guess would have been a PAL/GAL
of some kind, but I can't immediately think of any standard parts that
would have had less than 20 pins there either...

Thanks Bob- this is alongside the 27S29 parts- which are labeled as such,
but this question is about a part labeled AM76 (different than the
27S29 which are clearly labeled).
Are you saying they're identical?

Classic Computer Fans,
I tried out the CYBIS release:

on the DtCYBER emulator when it first came out. I've since forgotten most
of what I'd learned. Recently I fired CYBIS back up and started relearning.
Does anyone know if any user mailing li

Had to fire up BasiliskII to find out what kind of Fortran I used on
Mac in 1988. Turned out it was Absoft Fortran 2.4 and seemed a bit
strange as I recall M$ was written on floppies that I got for
it. Did a bit of digging on internet today and, surprisingly, Absoft
still exists and continues
