Hello,
to help someone trying to resurect a lisa1 I added twiggy drive support to my emulator (IDLE).
Since some twiggy floppy were imaged by bitsavers.org there is some content to test.
Emulation is not perfect because clamping/unclamping is not fully tested (& I do not have a lisa1 system to test) but LOS 1.00 can be installed.
Source code only, tested on linux (a binary exists for windows but my compilation environment is a bit broken for vista and above...).
http://sourceforge.net/p/idle-lisa-emu/code/HEAD/tree/
(now with svn since cvs support was dropped by sourceforge).
You will need rev C cpu roms to test a lisa 1. They are somewhere on the net in intel hex form (need to convert to plain binary).
