The ICM7170, Am7990 (lance), AM7992, Z8530 I don't see a way to<br>
replace (unless by re-implementing in programmable logic, or having a<br>
go at recreating them with open-source EDA & PDK perhaps as FOSH, but<br>
that's not happening anytime soon).<br></blockquote><div><br></div><div>Depending on how far you want to stray from the original, would one of the Am7990 descendents be a possibility? Not the PCI stuff, but something like the AM79c96x line are electrically different-but-not-terrible than the 7990, and have the bonus of having (some) software compatibility. I'm not sure the 96x chips are any easier to source than 7990/79c90s tho.<br><br></div><div>Similarly, for the Z8530, perhaps the Z85230/Z85233.
