Nobody will run Genera without TCP/IP and a lot of other stuff.
The error handler is not the same anymore.

I think that's pure fantasy.

I don't think that was a goal, given that the MIT system was not relevant anymore and the vendors all had their own forks. TI converted much of the old code to Common Lisp with a translator. Symbolics wrote most new code in Common Lisp.
Without an extensive implementation of Common Lisp incl. CLOS, basically nothing runs on the old system.
The times of a few conditional reader macros was soon over.
Does Portable Common LOOPS (PCL) run on the MIT Lisp Machine?

It lacks a port, but there are ports to TI and Symbolics. That should be simple.
