Hi,

I am trying to build a single board computer based on the '332 and '382
chips.
I've got the chips ('C201 TCU, '332 CPU, '382 MMU) but...
In NSC's "Microprocessor Databook" they show an "Interface suggestion"
where they use "Bus Control Logic" to generate the RD, WR, TS0, DBE, RDY
signals from the CPU and MMU signals rather than using the logic built
into the 'C201.

1. Why is this?
2. What does this "Bus Control Logic" look like?
   Can I get away with just a PAL or is it a project on it's own?
