Who is Robert Cray? Any relation to Seymour?
Robert Cray always bragged that the newest Apple was designed with a Cray,
whereas the newest Cray was designed with an Apple. A superlative example
of the KISS principle, if it's true.

MicroBlaze is free with Vivado and the Digilent Nexys4 I am using has a
Xilinx Artix 7 XC7A100T on it, which allows one to use Vivado for free
on it, via a WebPack license (The free WebPack license is restricted to
certain chips.)

Make that "fuse-link PROMs". My mistake.

I did say that (with a pun): "Intel Memory Systems was very big in the

The "mod revival" occurred in the UK in the late 1970s.

can anyone tell me what this is (manufacturer)? The font and such looks
similar to the panel you are discussing in this thread.

Intel used to brag in its ads that it manufactured more memory than IBM.

The only PALs I can find are the 'logic units' in the video memory
updating circuitry. That circuitry is

Hard to say, without the modules they came from.
As far as my (limited) understanding of vacuum tube logic goes, double triodes
were very common for implementing basic boolean logic functions. Therefore,
most IBM vacuum tube computers and data processing machines would have
hundreds/thousands
While going through my assortment of old vacuum tubes looking for audio
treasures, I found a handful of IBM branded ones. Mostly 5965, but
there's one 5963 mixed in.
These are dual triodes with the same pinout as common small-signal audio
tubes such as 12AX7/7025/ECC83, but characteristics

Very cool!
I know of MicroBlaze, but always thought it wasn't free?

Actually, Al was hired as an Apple Fellow in 1985. His first project was
"Trojan" a 68000 mac on an ISA card that mixed EGA and square pixel Mac
video. I was the Mac-side programmer on the project. Marketing killed it
before it got from ATG to product development.
That is wild! That would

Hopefully it's not whisker regrowth. That would be really frustrating.

Somehow it seems the thread got fragmented. I posted it to the other half of
this thread.
Here’s a link to a high-quality picture of the front panel, straight from the
listing. Turns out i’m crap at taking steady photos
https://i.ebayimg.com/images/g/dysAAOSwqqJehZ-Y/s-l1600.jpg
PDP-10 was 36-bit. You’re thinking of the PDP-1, 4, 7, 9 and 15 line of
computers.
However, it’s not actually 18-bit, but 2 8-bit bytes with parity for each byte.
If it is indeed an early Intel memory addon for minicomputers, i’d expect it to
be for the 16-bit DG Nova or PDP-11 line of
