Looking for Prompt-475

[dwight]

It had been a long time since I'd worked at Intel

but I recall having to use a different UPP board for each.

I worked on the UPP with the 4040 uP.

I was a test engineer for its end of life. Debugging these was

a pain in the butt so I made what I called a slowtime-ice.

I'd replace the 4004 with my umbilical and talk to the various

4002s and 4001. Although, I wasn't suppose to, I had a dump

of the ROMs to compare with.

We were our own last customer to order 4001s.

Dwight

Yes.  I also have both so not an issue.  Doesn't hurt that I was an
microprocessors and peripherals aps-engineer
when both were the drug on the market so I know the difference and how
to do either.  I'm more interested in
8755A as I have a few tubes of virgin NEC parts.

It is.  The 8755 is the generic name as they were replaced by the 8755A
fairly early in the parts life.
Its likely I have to build it as they are scarce and fairly simple. The
Intel schematic is helpful in it saves
me time I may end of designing it myself.
