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
limited in how it worked. The program flow was
just one big loop. Multiplying was a pain because
it was a bit at a time. If it was a constant, there
were often tricks you could play. It was to
have a MIPs speed of 10MHz but I don't think they
ever got beyond 8MHz before it got cancelled.
Still, if you knew how to make it work, it was
an interesting part. It could be programmed to
make a spectrum analyser that would display on
an oscilloscope that had x-y control. They had an
Ap note showing how to do it.
 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.
