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.

It sounds interesting, if somewhat esoteric. Why not put it on Github?
There it can be preserved (we hope), searched, perused, and by the curious, downloaded :)

I've never had any success with github, probably for lack of not really
needing it.
I've put my V70 materials, including 1130 emulator, on
http://vandyke.mynetgear.com/1401/V70
The next level up, http://vandyke.mynetgear.com/1401, has my 1401
materials, and several others, not very well organized.
Feel free to copy anything to github.

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