I want to do it too, along with others in my Vintage Computer Club. Perhaps we'll pick something that hasn't been done yet. Eric

I have scanned most of the software listings CHM > has in the archives and put them up on bitsavers. The B5500 was the first computer I did any programming on, when I was about nine. Not so much later, it was sold. I then rediscovered programming some years later, first on an HP 9810A, and then OS/360 Fortran. It would be nice to try the B5500 again, though software emulation (instead of FPGA emulation) would probably be just fine.

I thought someone had copies of the microcode, but then again maybe that is what they meant. Are there no copies of the actual ROS available in museums? -- glen

That's a line that deserves to be put above the entrance to a computer museum. -- As we enjoy great advantages from the inventions of others, we should be glad of an opportunity to serve others by any invention of ours; and this we should do freely and generously.

Typo, this was what I actually meant to say "Reanimating early computing dinosaurs from surviving DNA is difficult." |
