For starters, the first IBM-PC came with PC-DOS and not MS-DOS. As IBM
bought the rights to it for $80,000 and they could make and sell as many
copies as they wanted. They was no reason for a MS-DOS v1, since there
was no other computers that it would run on, besides the ones that came
with PC-DOS and you already have that.

Yes Tim Patterson did work for SCP when he created QDOS. Which Bill
Gates bought from SCP for $50,000. And later Microsoft hired Tim
himself.

And no, the version numbers were different between PC-DOS and MS-DOS.
They did this on purpose so you wouldn't get the two confused. For
example, any DOS version (meaning MS-DOS or PC-DOS) v3.30 was just
PC-DOS and no MS-DOS version by that name.

Yes the early PC-DOS did not include Basic, while MS-DOS did and it was
called GWBasic. That reason was the real IBM-PC had Basic in ROM built
into the computer. As the BIOS tried to boot up from floppy first and if
that failed, booted Basic from ROM. MS-DOS didn't have this feature. But
it still had Basic on boot floppy.

I never heard of 86-DOS.

> There were versions much earlier than you used.

You mean earlier than I remember. Which is a big difference. As I
remember the first IBM-PC and it was a dog. It came with PC-DOS and not
MS-DOS. And it had no idea what a folder (aka subdirectory) was.
