How about a serial bus? Physically simple and not too awful logically
today. Say, I2C or SPI...

Say USB-version 101101100 :)
I would say use a 68000 if your still can get them,
but run with a 6800 style clock. The master CPU and
shared memory on the high phase of the clock. The
slave CPU's on the low clock PHASE (clocked by a inverted clock).
This will give you multi-processing with a bit more than
64KB.
