IBM chose Microsoft's Quick & Dirty Operating System instead of CP/M for
its new line of PCs. QDOS (along with the abomination known as EDLIN) had
been acquired from a Seattle man, Tim Paterson, for the paltry sum of
$50,000. "Quick" and "Dirty" were truly an accurate description of this
system, because IBM's quality assurance department discovered 300 bugs in
QDOS's 8,000 lines of assember code (that's about 1 bug per 27 lines --
which, at the time, was appalling, but compared with Windows 98 today, it
really wasn't that shabby).
Thanks in part to IBM's new marketing slogan, "Nobody Ever Got Fired For
Choosing IBM(tm)", and the release of the VisiCalc spreadsheet program
that everybody and their brother wanted, IBM PCs running DOS flew off the
shelves and, unfortunately, secured Microsoft's runaway success. Bill
Gates was now on his way to the Billionaire's Club; his days as a mediocre
programmer were long gone: he was now a Suit. The only lines of code he
would ever see would be the passcodes to his Swiss bank accounts.
