Can I see the CPLD code?  I am working on something very similar for
the Altair.  I'm using the AVR as a MMC to 8bit bus bridge, and like
you said the AVR is way too slow to handle the bus.  I am using a CPLD
to handle all of the bus signals.  Right now the CPLD asserts a signal
to the AVR when the AVR is needed, and the AVR clears the wait line
when its done.  I haven't had the time to see what the times actually
are.  I would love to see exactly how you are doing things.  A 2MHz
8080 might be close to a 2MHz 6502.
