No it's not really any OS. In the docs it's referred to as both Microsoft Works, and as HHOS (Hand Held OS). It's just a set of MS applications and a menu, kinda sorta barely like a model 100, except no BASIC, and the memory map and executable format are totally different.
>From what I can tell reading the developers document, the executable format is actually an ordinary MS-DOS .exe, with the exe header removed and some other header put on. And for roms, almost the same thing but with a different header and a tail. That's not to say an existing dos binary could be converted and run. Aside from the headers, the app itself would try to access the wrong bios calls and memory addresses and hardware etc. But it looks like you could use ordinary dos compilers and assemblers to make an ordinary dos .exe, and then convert that to a form that runs on a 600. I theory. In reality, we would need a copy of that ms works utility disk, which has the developer tools. It might be possible to reverse engineer the process by reading that developer document, and looking at the few executables and roms we do have. -- bkw On Jan 22, 2017 11:35 AM, "Chris Fezzler" <fezz...@yahoo.com> wrote: > Great job Brian.
