Hi,
To get back to computers for a change...
While looking for some op-amp chips earlier I came across a
couple of 8751s (labelled Intel '80). A quick google search
failed to turn up a data sheet, anyone any ideas where I can
look?

Hi Stan
These are the EPROM version of the 8051's. These can be
programmed and used just like the 8031's in keyboards or
used in place of a mask ROM 8051, when programmed. I don't recall
if Intel published the programming specs for these but there are
a lot of programmers that will program these ( often
with special adapters :( ). I think Data I/O's don't need
anything special other than the 40 pin socket. Look
for 8051 family manuals.
I think Intel stopped publishing programming specs when
they had different flavors of EPROMs with similar names.
They wanted to keep the programmer manufactures up to date
without worrying about hobbiest blowing their parts up.
