To all,
Some 20 years ago, I led the Computer History Museum's restoration of an
IBM 1620 Model 1 computer. Our team was successful in both bringing the
machine back to life and collecting a massive amount of manuals, books,
and software for the machine. Most notable the John Maniotes
collection. I can safely say that CHM has the largest collection of IBM
1620 material in the world.
We are still looking for IBM 1620 Model 1 manuals to add to collection.
Please let me know if you have anything that we might be missing.
In the past 2 years, several people have been writing simulators for the
IBM 1620 Model 2 that go well beyond SIMH's instruction-level
simulator. These simulators are based on the logic diagrams of the
machine and implement unusual corner cases as well as documented
functionality. One of the simulators has a text-based front panel while
another one has a full true-to-life graphical front panel. It's not my
place to formally announce either program, that's for the creators to do
once they complete their implementations. I've been consulting with the
engineers and am reaching out to the broader community for help.
What they need, and CHM would be very interested in adding to its IBM
1620 collection, is original software specifically for the IBM 1620
Model 2. Of particular interest are the IBM 1620 Monitor II and IBM
1620-2 diagnostics, but any Model 2 software would be helpful to their
efforts.
Please let me know if you have and IBM 1620 Model 2 software or manuals.
Thanks,
Dave Babcock
