I have a real Kaypro 2 computer with a 4MHz Z80 in it, which I also use Turbo Pascal on - on the Kaypro, it's perfectly usable, but you get used to waiting a few seconds when you're loading files, compiling, etc. On the ZedRipper, when things are executing out of RAM everything is instantaneous. I think the CPU core I'm using is close to cycle-accurate, so it probably is ~35x faster than the Kaypro when executing actual code.

Thank you. I absolutely refuse to get into retro computing. I refuse. I’m not going to. So I don’t think your amazing work has me at all interested. I have enough hobbies, and my wife knows it.
