There is a tremendous amount of software, most of it not portable, written for obsolete computers and obsolete operating systems. It would be very nice, I would think, if a collection of the historically interesting software could be made, and even nicer if it could be run. It is not practical to run the old machines, but it should be very practical to emulate them. The tough part is providing enough emulation for the operating system (if that's where you want to put your interface) or the I/O hardware. Is there anyone working on a family of portable emulators for historically interesting machines? -s

I have an emulator for an IBM 650 machine. Unfortunately it runs on an IBM 709. But, not to worry. I also have an emulators for the IBM 704, 709, 7094, and 1401 that run on the Standard IC4000. Now if you care to write an emulator for the IC4000 I can send you a description of it. This will give the ability to run software for a reasonable number historical machines. I also have a meta assembler that runs on the Standard ES01 that will assemble programs for any of the machines mentioned in this note, among others. Marvin Rubinstein -- INTERACTIVE Systems Co.

I have an emulator for a VAX, for when it becomes a historically interesting machine. :-)

The 8 used 12-bit words, so he set up a 4096-entry jump table that did everything. Aside from clean design, it ran much faster than the original hardware. -- ## Bill Stewart, AT&T Bell Labs, Holmdel NJ 1-201-949-0705 ihnp4!ho95c!wcs

Ah, memory lane... I remember a guy from Georgia Tech who had written an emulator for a Burroughs B5500 which ran on a DEC PDP-8/e, and which was "about the same speed as the B5500" when compiling the Algol compiler (written in Burroughs Algol).
