After years without any modification... I updated my lisa emulator to test twiggy images found on bitsavers.org.
floppy emulation is still an state machine based roughly on the A8 rom unassembly (and now updated to handle 2 drive)
if in lisa2 mode you now need to insert your floppy in the Unit 2.
LOS1.00 installs on profile and runs but tools cannot start (it may be a problem in the bus error emulation).
Source only, linux tested only
