Yup. I am old enough to have posted cassettes rather than 5.25" floppies, although I was using a Z80-based machine that ran Forth and took 5.25" floppies as late as the early 90s. Wildly specialised bit of kit, and I wish I'd stolen it when I had the chance because it's probably been thrown over the side of an oil rig by now. The first Forth machine I used was the Jupiter Ace, which was a home computer sold in the UK by a couple of guys who spun their company off from Sinclair. It was a bit too underpowered and a bit too late and a bit too weird to really "land" - everyone either had a ZX Spectrum or a Commodore 64 by then, and schools and rich kids had BBC Micros (I got right into 6502 machine code on the one we had in school when I was about 9, and then got my hands on its predecessor, the Acorn Atom). I also had a couple of Epson HX20s that the company my dad worked for had used as data loggers, which had Forth ROMs fitted. That's how I got right into 6809 programming, and that chip is ludicrously suitable for Forth! I got Cosmic Conquest working on an Apple II emulator but the support code around getting it working is frankly terrifying. I used a fig-Forth disk, and wrote my own implementations of the graphics words used there, which I guess is what the original author did. Tracking them down has so far proved impossible, and it's quite likely they are no longer around.
