Hi Joe
'Not many 1702's made. They are truely rare. 1702A's were
by the milions. 1702B's were not made by Intel that had
already stopped producing them by then. I think AMD was
one of the manufactures of 1702B's. I have one someplace.
I don't have a 1702 but I do have a 1602
Chuckle! I had one to but Steve the chip collector HAD to have it. I
probably sold it way too cheap ($20). I found it in a prototyping shop that
was closing up about 2 years ago and I had to resurrect some long dead
brain cells to remember what it was! I couldn't find a dammed thing about
it online. Actually I think it's the ONLY one that I've ever seen. It's
barely mentioned in my old Intel data books, I doubt Intel sold very many
of them.
I'll have to dig out my stash of 1702?s and see if I have any straight
1702s.
Joe
that uses the
same algorythm as the 1702 does. I can program
1702's
with my sim4-01 setup but I'd need to change the code
a little to match. There is a hardware switch as well.
