Looking for Prompt-475

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.

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.
