Looking for pointers to old Control Data software

Dear Gary:

This is marvellous! I used to work quite a bit on a 3600 in 1968, and it is
good
to hear that there is some form of revitalization for that machine.
Unfortunately I have not retained any software from that time, so that I
cannot help you there.

However, I would be very interested in hearing any information about
the simulator you wrote. Is there / will there be a report on that project
somewhere ? Could you send any description ? How do you simulate
the console ? What do you do in hardware / in software ??

Interested in swapping ? I wrote a simulator for a Siemens S 2002, and I have
a copy of the Algol compiler that went with that machine (no operating
systems at that time, ca. 1960). The S2002 was a binary-coded-decimal
12 digit machine, the one I worked on had 10 K words of core and 10 K words
of drum, and all of that is in the simulator. I have compiled and executed
Algol programs on it - the simulation on a PC runs of course faster
than the original hardware at that time; do you have some timing
estimates for your simulator ?

Very best regards
John G. Zabolitzky
