What a coincidence. My company just upgraded their AS400/IBM i and nobody wanted to buy the old one, so it’s just sitting there. I think it’s a Power 8 Processor…
Nitpick: AS/400/i aren't mainframes, they're "mid-range" in IBM speak, or the last of the "minicomputers", a totally separate line from IBM 360/70/90/Z.
That could be a lot of fun to play with, especially if it has PowerVM.
Very cool! What compilers and interpreters are available? I know that rexx wasn't available at the time that the open source vm/370 was released. Has the community found a way to add rexx?
