I recently discovered an emulator for a minicomputer I used to work with in school and I've been having fun with it. But I got to the point where I wanted to be able to import/export files from it.
The Hercules emulator for IBM's System/360 technology supports a full set of peripherals, but the minicomputer doesn't have any unit-record device emulation. Not even sure it has a line-printer emulation. I may end up adding those devices.
But one thing led to another. It's been a long-standing joke that someday I may take some Legos and Arduino and homebrew a physical punched card reader, but I ran across a posting on the Hackaday website where someone had bought an actual desktop reader unit on Ebay and I thought I'd see if they were still easy to get.
Nope. In fact, even used punch cards are now selling for up to 80 cents a card! I'm sitting on a gold mine here!
Incidentally, if anyone knows anyone who has some ancient QIC-250 tapes (Colorado Memory Systems) and want to get data off them, I have several tape units I don't want anymore. Tried to flog them on EBay, but no nibbles. I tested one before I posted it and it worked file (although ancient tapes have to be carefully re-tensioned or it will eat them like a cheap car cassette unit). Otherwise I'm going to have to pitch them. Seems a shame but no one wants a 250/500MB cartridge device that runs off a floppy disk controller any more.
