I remember the price was for the IBM-PC bundle and that DR was uncomfortable with it. I also remember CP/M came bundled with many Z-80-based computers of the time - there was not enough hardware standardization to allow shrink-wrapped cross-platform operating systems to exist. > The other option on the IBM PC was UCSD p-system, which was fatally crippled by the overhead of the interpretation layer UCSD p-system was cross-platform, at least. > -- we didn't yet have JIT.

I suppose we may have arrived at a set of basic compatible APIs, much like POSIX, that allowed software designed for it to run on many different computers. > I submit that the most likely scenario would've been a duopoly -- Apple with the home and education market, IBM with the business market. And Commodore and Atari sharing the home/gaming market in the US, Acorn and Sinclair in the UK. Commodore would possibly own TV and special effects. 68K (or ARM) based 32-bit boxes would be considered basic home machines and the average person would have access to preemptive multitasking in the mid 80's. |
