Hi Dave
If you are going for a complete Intel chip collection,
this is a rare bird indeed. This was an early attempt
by Intel to get into the telco market. It is a
DSP chip that had an EPROM inside. It was somewhat
...
I have about 6 chips of which, only one is
functional. That is why I'm still on the lookout
for another. I'm afraid to mess with the last working
one I might ever see.
I got a strange board from a previous employer (who made teleconferencing
equipment) labeled Intel SDK-2920. I fooled around with it a little bit,
not really knowing what it was. It has an 8085 for the CPU on the
"programmer" side, 1 kB of SRAM (2 2114's), a 24-character
14-segment-per-character LED display, and of course the EPROM programmer.
On the "execute" side there are 4 analog signal channels, only one
populated, (each containing 2 2912 IC's and some passives) and then one
socket for the 2920 that runs the whole mess. And yes, I have a 2920 for
it which I think is good, because it reports "EPROM BLANK" when I try to
dump the program out of it. The die inside the 2920 is mounted cockeyed-
and it's huge, some parts of it are outside the limits of the quartz
window.
Just letting you knwo that more of the weird stuff exists out there,
