Van,
I think the IBM 1130 group would be interested.

Subject: IBM 1130 simulator
In about 1974, for my senior undergraduate project, I wrote microcode to
convince a Varian V70 that it was actually an IBM 1130.
Being substantially more modern hardware, it was much faster than a real
1130.
If anybody wants microcode and flow diagrams, and listings for the I/O
simulation (which ran in 620/f mode), I'm happy to send them.
