- Bssst. Thanks for playing...
- There are several software emulators to run MS-DOS and DOS applications on
- non-Intel CPU's. Soft-PC may be the most well known. They have a package
- for MAC's, which do not have a Intel CPU, and SPARC's (Sun SparcStations)
- which also doesn't have a Intel CPU.
- Neither of the CPU's can -run Intel code- but they both do execute intel binary
- code by reading it, and -converting- it into native code (a gross
- simplification).
-
- A version of MS-DOS could be written for almost any native CPU available,
- but I suppose the MS could be forced to be dropped from it...
- Of course the software emulator was specifically excluded from the discussion.
- The real point may be put that the original question may well still be flawed.
- I'm not sure what value the question or answer is, but generally, I'd say the
- best answer is no. There is no msdos or dos computer that does not have a
- Intel CPU as a core cpu. The DEC Rainbow 100 & 100+ computer may have come
- the closest, it had a 8086 and a Z80. As I understand it, the Z80 assisted
- in the video partion of the system, and it required a special version of dos
- to run on it because of the Z80. Versions 2.10, & 3.10 are available for it
- currently. WANG may have made a DOS or MSDOS for a non-Intel cpu I don't know.
- Anyway, David's real point may have been, even if a DOS or MSDOS is available
- for a non-Intel cpu system, DOS applications would have to be run between e
- either a software emulator or a binary converter, in order to run, because
- Intel binary code (programs) are written for a hardware platform (aka a intel
- cpu,) AND a OS like dos.
