As I have it it only supports 1k of I/O mapping ($0000 to $03FF) which covers just about every non PnP card I've seen. If memory addressing were needed that could perhaps be arranged as 256 x 256 byte pages or something similar. >> BTW, does the 3c509-series work properly in 8-bit mode? > ..

If this is the straight 3C509 then it had problems, with the 'B' and later you have to pull the 16 bit line down below 0.6v to make it work reliably. > Drivers for serial and line-printer would be trivial.

An awfull lot of VGA cards (Trident etc.) were only 8 bit in spite of their 16 bit edge connectors. The same is true of a lot of sound cards.
