- Hello all,
-
- As the MC68901 is off the market, and the replacement 'HC901 hasn't
- been introduced yet, I was thinking about connecting a Z8090 aka
- Z80 KIO to my 68020 system. At under $10, this part offers two serial
- ports, 16 I/O bits, 3 timers and some more stuff in a 84-pin PLCC
- package.
-
- The programming of this chip shouldn't be too hard (I have all the
- Zilog manuals left over from my last life). However, I still have to
- connect the chip, which means getting the timing right :-(.
- It doesn't seem to be too hard (from the manual), but I am still
- *very* interested to hear from anyone who has attempted this unusual
- combination before.
-
- Thanks in advance,
-
- Jan-Derk Bakker.
