Re: "Put the eggplant in the pot"
> CP/M playing a role in the history of MS OSes is not the same as deploying CP/M as-is. Which is what I suggested would not have been successful in the home.
CP/M is just as (un)usable as MSDOS/PCDOS. And *neither* of those was particularly prevalent in the older home computers, as the interesting variety of home computers had OSes that were a lot more useful to the home users than either of them.
When home - and teeny tiny business - users bought more "grown up" computers, I'd claim that CP/M was actually way *MORE* successful those markets than MSDOS ever was: I give you the Amstrad PCW and LocoScript just for starters. Whilst the big business world pretended their 8-bit IBM XT's were really 16-bit or more, you could do all the useful stuff on a stout, non-pretentious Z80.
By the time that home users started getting IBM compatibles in greater numbers than the specifically "home" computers, we had all moved on from *BOTH* raw MSDOS and CP/M, so any question about whether CP/M (well, CP/M86) would have been successful in the home is totally irrelevant. Domestic users were well used to WIMPs (and then GUIs!) and the fact that we techies all knew that - that thing from those people - was actually just hiding MSDOS from us was of utter disinterest to the home user. Irritating, but not interesting.
If CP/M had won the coin toss, been *the* command-line OS of choice for business, and reached the percentage penetration in that arena as it did in the home market (albeit hidden under such as the Locomotion menu), then the WIMP that captured the final market share could have been built on top of CP/M just as easily as it actually was on top of MSDOS. Marketing, not ability, was in play.
What business users *did* do for the domestic market was just simply play the game of providing a market into which more and more CPUs could be sold, so they got cheaper and cheaper. The machines from the desks of the drones, the least interesting computers in the business arsenal, became packaged and marketed for the home. Because business went down the PCDOS trouser leg of time (due to marketing, not merit) CP/M lost. Nothing more dramatic than that. Going down the other leg would not have made any difference to the domestic market at all.
Actually, no, I take that back: the domestic market would have been better served had CP/M kept its place, as we already had MP/M and sharing the home computer would have been more secure. And there was more software available for CP/M, as it was a mature product compared to PCDOS, so we'd be just a few years further down the road instead of having to have waited for PCDOS to catch up.
