Does anyone know anything about Zitel? Pr what bus this card uses or
anything about the card? <http://www.classiccmp.org/hp/a4/zitel.jpg>. I
seem to remember that Zitel was a copy cat of Intel.

It looks like 2 banks of 16 bit RAM with parity. As a RAM
board, it shouldn't be too hard to trace out the address
selects.
What size RAMs are they?
Oops! Sorry I meant to include that and forgot. The RAMS are MM 5280Js. I
think they're 4k x 1 SRAMs. That would make it two banks of 4k x 17 bits.
I'm not worried about tracing out the pinout since it doesn't look like
anything I can use (except for parts). I was more curious about Zitel and
what bus this might be.
