Yes, I remember.  I ordered the original PC in September of 1981.
I ordered both CPM-86 and MSDOS with the hardware.  But it took about
6 months before my system was delivered.  By that time, the market had
already decided on MSDOS, probably because of the $40 price, and I cancelled
the CPM-86 (about $195?).  Later, in December of 1983, I dropped MSDOS
altogether and switched to Venix/86 ($995, I think, but I traded a Maynard
disk driver for the software).  By then, I had a 10MB hard disk and a
5MB removable Syquest drive.
