There is also the LMI source tree.

I made a suggestion a while back that someone or small group of people
could make a business proposal to new Symbolics to port OpenGenera to
AMD64 and/or G5 in exchange for X number of licences to use the result.

I have booted ITS on the simh emulator, lack of hardware shouldn't be
the sticking point.

Which emulator ?

Exploiter is stuck at trying to work out what one of the options to
switch a stack group needs to do.

Nevermore is probably only suffering from too much real life.

I have been a bit too busy with learning how to program FPGAs and
with some family stuff to do anything for the last few months.
