I had heard the DP5380 had bugs, but didn't know the extent of them. It's
precisely this experience that's useful to us, though. The derivative chips
(dp8490, 53c80, 53c90) chips were more what I meant, and the similarity can
be useful. Choosing a chip that's a complete unknown leads to a repeat
performance (return of the plague).

NCR 53cf90 sounds fine, assuming the pricing holds (US$19.45). I assume
the "cf" is faster than the "c"? The data you gave didn't say why one would
pay the US$1.85 more for the "cf".
You know, I've been watching/collecting data on chips like this for years,
and do you think I can find any of it in my office now? Not a chance.
