I’ve been working on a CP/M port to the Amstrad NC200 Z80 laptop, using my reverse engineering of the floppy disk boot sequence; it runs CP/M really well, although the screen’s pretty small.

Once I got it mostly working, I went trawling through the archives for fun software I could run on it. It turns out that the NC200’s 720kB floppy disk drive is huge by CP/M standards. This video is the result.

I’m still packaging up the CP/M port and trying to sort out licensing in 35-year-old software; watch this space…
