The 102 was about 3/8" thinner than the 100 as I recall, and about a
pound lighter. I always thought they felt a bit flimsyas a result of
that. The 102 expansion bus was definitely an improvement over that
of the 100, especially if you were inclined to connect it to the disk
video system -- even with the ZIF socket, the end of that cable was
all too fragile.

IIRC the
M102 was a smaller machine that used standard 8K RAM chips
rather than the 4-2K-RAM hybrids used on the M100. Apart from that it was
very similar.
Actually the machines are the same size. The PF keys are deeper on the 102 and it has a "System Expansion"
port on the back. Other than that it
appears to be the same externally.
The 'System Expansion' connector is the 8085 bus + a few extra lines.
It's brought out to a 40 pin DIL socket on the bottom of the M100 under a
flap. AFAIK the pinouts are 'equivalent' in the sense that a piece of IDC
ribbon cable with the appropriate connector plugged into either machine
will have the same signals.
