They collected on ISA patents in any case. *MUCH* money was
collected on these patents.

Nonsense. That's the common press.
Microchannel was before its time. Too complicated and too
expensive, but more so, too IBM (patents royalties had little to
do with it). The industry revolted at MC much as they did on
Intel/RAMBus. Unfortunately that revolt set the industry back
five (or more) years. EISA, what a joy that was!
MC was designed to solve one major problem: system
administration. ISA was an abortion from the day it was
conceived. The electrical characteristics were garbage from day
one. MC was a *huge* advance, but the real story was PnP.
