A random board I came across by accident - low production run, but decent despite that.
The board uses an USB-stick for storage, formatted as a FAT filesystem which makes exchanging files between this and another system easy - though of course you can transfer files over the serial port.
The biggest issue is that the board has only 62k of RAM so I'm stuck with CP/M 2.2, rather than 3.0 which requires paging-support. Still I can run infocom games, BASIC, Turbo Pascal, and other retro things.
- jacquesm 3y agoI'd love to know more about your board, it sounds like a very interesting one. Is it in S100 bus format or something bespoke?
- stevekemp 3y agoSomething bespoke. My code repository contains a link to a youtube channel where the board was discussed, and where I found it randomly. But sadly the upstream site of the provider and the (useful) forums it hosted are gone unless you use the wayback machine: https://github.com/skx/z80-playground-cpm-fat https://github.com/skx/z80-playground-cpm-fat
- AlexeyBrin 3y agoAs an alternative - Agon Light 2 (eZ80 CPU). By default it comes with BBC BASIC modified to take advantage of 24 bits addressing, but it can run CP/M if you want. The nice thing about Agon is that it can run standalone if you add to it a keyboard and a VGA display.
