This runs off of an unofficial emulator that is a monstrous hack. There are lots of gotchas, bugs and so on.

On the other hand, an official emulator is in the works and should be released at some point.

Wait, what do you mean? The current owner of Symbolics authorized the development of a new I-Machine emulator? Who is working on it, Kalman Reti and Brad Parker? This is very interesting news, please elaborate.

I don’t think Brad Parker is involved. You can email Reti for more information.

What is his current email address? The one at symbolics-dks.com?
