Bob - re: "AMD helped Intel out by being the mandatory second sourcing option. Otherwise, the IBM PC would probably have had a Motorola chip."

IBM selected the Intel 8088 in 1980 for its CPU for the original IBM PC.

IBM's design choice was based on AVAILABILITY and BACKWARD COMPATABILITY with existing 8 bit CPM-based software - despite CPM not becoming the OS of choice (Originally, CPM was expected to be the OS - but Gary Kildall became a footnote in history over his handling of IBM and their requests).

In 1980, the Motorola 68000 still didn't work properly - and Motorola's use of hand layout techniques (NO REAL CAD TOOLS at that time) - wouldn't get them useable parts until 1981 - on or around the time of the PUBLIC LAUNCH of the Moto 68000.

That left out the Motorola 68000 from the get-go.

Intel did not cross license AMD on the 8086 until 1982 - two years later - but, as you noted, under pressure from IBM.

You are close, but IBM chose Intel 8088 because they already had licensed it, and Motorola could not deliver in time to meet IBM's commitment to Sears. One of the great sales by Intel in "Operation Crush."
