IBM released the PC onto the world.
For the occasion here is 86-DOS fished out from 86-dos.org This is what was sold to Microsoft as the basis for MS-DOS.
You too can behold this ancient gem here.
Maybe I should do something about the various versions and hunt out something capable of running MS-DOS 1.25.. I’m sure Peter has something for the occasion!
Oh and I have to add this bit from olduse.net …
|“Out of today’s mail: Electronics, June 16, 1981:Under the heading (pg. 33) “Xerox to market personal computer…”
with the announcement of the 820 which most of you may have seen already, is “… with IBM to follow suit” Called Chess, it is an 8088-based system priced between $3-4K, and includes two DSDD 5-1/4 Tandon floppy drives, a detachable keyboard. An OS “similar to CP/M” from Microsoft (IBM Personal Computer DOS), from 64K to 256K RAM, and a “600-by-400-line” B&W display and able to handle eight colors with a resolution of 400×200 pixels or four colors at 800×400. Look for it to be announced next month and check out Sears, Computerland, and maybe J.C. Penney.”
The first mention of the IBM PC on usenet…
