8088/XT DOS as a build target ?

[Arawn-Davies]

Hi, I've really enjoyed the simplicity of running CPM binaries that RunCPM has provided, so I've used it on both desktop and on an Arduino Due project of mine.

I've recently bought a Book 8088 V2 that has a NEC V20 CPU, while 8-bit external bus it's of course a 8086 internally with improvements etc. It's also got a full 640Kb (more than anyone would ever need surely?) 😂 and an XT-IDE ROM that provides modern compact flash support.

I feel like it could be a great platform to run RunCPM on, as it supports MS-DOS 6.22 but I don't know how much of RunCPM could be used with a suitable compiler :) I'm happy to look into it or see if there's any other solutions, as the BIOS on the Book 8088 V2 makes it hard to use CPM on it at all
