I had not realized that 43 yrs. ago Microsoft purchased 86-DOS for

what
8-bit machines could do!
Initially MS-DOS and PC-DOS differed only in name and trivial items,
such as "IO.SYS" and "MSDOS.SYS" being renamed "IBMBIO.COM" and
"IBMDOS.COM"
When changes were made, Microsoft's and IBM's version numbers were
separated.

And I learned last week that DOS is still alive, and well, and damned
expensive.
Tuxera Systems acquired Datalight in 2019 and now sells ROM-DOS. They
claim it's still fully compatible with MS-DOS.
Single User ROM-DOS costs $55 USD, and the SDK for building it embedded
is "Call for a Quote".
They're apparently pretty active with the Cease & Desist action - none
of their products are "out there" in the usual places.
Long Live DOS!
