The original Lisa was going to be a 2901 based machine running a variant of
P-Code. This died off pretty quickly once the 68000 was announced.

I assume David Craig has this all documented somewhere. I heard the early
history from Paul Baker. Lisa had been going for a while before Larry came
over from PARC. Just before Larry left Apple, there was an internal talk on
Lisa history which gave a chronology of events. Maybe Larry has written this
all up somewhere.

See the previous message. It was written by Silicon Valley Software
