Lisa System Diagnostics 889-4002-D (Twiggy)

[ried]

Lisa System Diagnostics is a bootable Twiggy disk, Apple part number 889-4002-D. I can't find any information about this disk online, and figure it's worth archiving here so folks can explore it.

After booting up, the Lisa automatically begins a test sequence by executing a series of files. I do not know how long this will run for, but it seems pretty exhaustive. This is not the same as Lisa Test.
