Phase III -
Characterized by the start of LSI. Hardware costs were
still high and operating systems were mostly bundled. Volume was
still low in most cases - up to about 1985 - IBM was still the major
player, but no longer so dominant
MSDOS wasn't available separate from the hardware until much later.
I remember running a copied version of DOS on a brand new '286 clone
I built from parts purchased from Jameco. I searched high and low,
and couldn't find MSDOS unbundled anywhere. This was about a year or
so after the '286 was released (early '90s? I don't remember)
Also not quite right... alhtough it certainly wasn't a shrink-wrapped
product, you could purchase MS-DOS without hardware by buying the
Binary Adaptation Kit. These were available from at least MS-DOS 1.25,
and maybe for MS-DOS 1.1 as well.
Pretty cool, you got .OBJ files (or were they still .REL files?) for
most of DOS, and source for drivers and utilities (ANSI.SYS and
PRINT.COM
come to mind).
