This I can believe. It's reasonably well known that the first PC design was deliberately crippled in order not to impact on sales of the dedicated word processor, the IBM Displaywriter.

The 8086 was thought too powerful and would compete against existing IBM products, so the 8088 was chosen. Other changes to expansion and bus architecture were on the same basis.

I spent over a decade completely failing to understand how it could succeed against Amiga.
