   The Z-RAm was a memory expansion card AND Z-80 card for the //c, giving it
CP/M capabilities.  Least, that's what I remember about the AE products.

  Sounds like 2 Megs to me.  8 chips equals 1 Meg in the Apple world, anyways.

  Yeah, unplug the CPU chip, plug it into the empty socket, and plug the
piggyback onto the empty CPU socket on the motherboard.

  Must be a part of the Z-80 processor.  I remember seeing Z-80 processors in
PLCC format towards the end of their popularity.
