- Actually all you'll need is parallel -> serial conversion. There is no

- No much expansion. You can probably use the spare chip select line in the
- real time clock. You really want to use all 32-bit data bus for this for
- speed. Otherwise software would be faster. The lack of Zorro slot does
- not imply lack of ZII config protocol. The software doesn't know about that.
- Using TTL chip should be fast enough even at 14MHz.

- Have you consider doing it in a PLD ?
