This information shows how the Lisa computer physically looked. There were basically twos Lisas; the Lisa 1 and the Lisa 2 models. The Lisa 1 contained two floppy drives, the infamous Twiggy drives. The Lisa 2 replaced the Twiggies with a single lower capacity Sony 3.5” micro-drive. The overall appearance of the Lisa is rather unique (at least to me). LisaTest was the diagnostic disk which Lisa owners could use to diagnose Lisa problems.
