Anyone know what this is? "Great Little Machine" prototype

Hmmm, looking at this again, it has 64 pins on the connector, the Lisa has only 56. I did see the Lisa 2/10 motherboard have extra pins upto 64 but the ZIF connectors do not. So perhaps this was something considered before the 2/10 was released, or it was for some totally different machine, or something that was supposed to be backwards compatible with the Lisa's expansion slots.
Or they happened to have slightly longer ZIF connectors and tooling for Lisa PCB boards and they built this thing from the same stuff they had available.
There's one tell there, there's a hole right above pin 64, just like on normal Lisa cards, there's a hole right above pin 56 to hold a brake pin.
Whatever this thing was, the case it wanted to be in was at an angle, just like the Lisa's on the side facing the outside.

Interesting, while looking through the monitor v12 source code on bitsavers for the thread w/Tom Stepleton, I ran across this. There's a define to use Lisa or Little.This version of Monitor is around the Lisa 1 days, so the GLM proto was around that time and was using Monitor.
The define just changes the vector of Macsbug abort used and not too much else. Still, it's a clue.
