- Here is the information that I have, from The Great Microprocessor
- list... It's only slightly blatantly biased...

- Part IV: Intel 8086, IBM's choice (1978)
-
- [...general description of the 8086 and related processors...]
-
- So why did IBM chose the 8086 series when most of the alternatives
- were so much better? Apparently IBM's own engineers wanted to use the
- 68000, and it was used later in the forgotten IBM Instruments 9000
- Laboratory Computer, but IBM already had rights to manufacture the
- 8086, in exchange for giving Intel the rights to it's bubble memory
- designs. Apparently IBM was using 8086-types in the IBM Displaywriter
- word processor.
- Other factors were the 8-bit 8088 version, which could use existing
- 8085-type components, and allowed the computer to be based on a
- modified 8085 design. 68000 components were not widely available,
- though it could use 6800 components to an extent.
- Intel bubble memory was on the market for a while, but faded away
- as better and cheaper memory technologies arrived.
