Z80 or 8080 to 8086 is not too bad but the other way is plain nuts.
> 2) It was 3K when assembled into TED.COM Its not nice code either. It assumes a memory mapped video, as in the usual PC video. Kaypro is a pretty close example of that but this will not be used on a kaypro. The executable did run ok in .dosemu. > 3) Was full screen.

For S100 that would be a PT VDM-1,or one of the similar flavors. If it were my usual S100/Kaypro/AMproLB+ or any of the CP/M machines I have its VEDIT. But this machine is maybe 1/3rd the size of a S100 card. All IO is serial initially. Allison
