There's a second Lisa emulator, idle (Incomplete Draft of a Lisa Emulator):

  https://idle-lisa-emu.sourceforge.net

There are quite a lot of activities around the Lisa right now. A number of projects recreate the Lisa hardware using (mostly) original components:

https://github.com/warmech/lisa-hardware/

https://github.com/alexthecat123/Lisa-PCBs/

https://github.com/alexthecat123/Lisa-GALSCSI-Card/

Patrick Schäfer has provided Lisa hardware and tools for many years:

and there is an Arduino-based ProFile hard disk emulator (currently only working with the Lisa 2/5 I/O board):

...plus one based on a BeagleBoard:

...bigmessowires' floppy emulator, which also works with Lisas

...and, of course, the Lisa OS and application source code which was published in early 2023:

...plus more interesting source code including GEM, e.g. available at:

Thanks for the links.
Here is yet another one: https://github.com/rochus-keller/LisaPascal

  Ah, darn, I knew I wanted to add your repos, sorry. Thanks for the reminder!
  Are you planning to extend the compiler into a full Pascal cross compiler for the Lisa? That would be _very_ nice to have...

    I spent quite some time studying the Pascal and Assembler source code, but could not resolve all symbols, and there are also several ambiguities, which led me to the conclusion that I would also have to build an interpreter for all the build related files and try to reconstruct a complete build with the correct options in order to be able to make any statement about the completeness and integrity of the code. That would take a lot of time at the expense of my other interests. That's why I've put the project on hold for the time being.
