wonder why microchannel for the microcomputer market never took off.
I'm not sure it's fair to say that it never took off. It was very
popular for a long time. Many manufacturers made MCA cards. It was
also big in the RS/6000 world.
How many people outside of IBM cloned it though? It definitely didn't
survive as long as PCI.
Cloned or made boards for it? There were a few 3rd party motherboard
manufacturers that licensed MCA, but I don't remember their names offhand.
As far as board manufacturers go (some licensed, some not), that I know of
included 3Com, Western Digital, SMC, Adaptec, Corel (SCSI boards, I still
have one), BusTek/BusLogic(Mylex), DPT, Kingston Technology...
FWIW, both PCI and ISA are /still/ very popular for industrial / single
board (backplane) computers that are often used in mission critical
applications. I can't say I've seen either MCA or EISA used in anything
lately though.
