Yeah. Every time I think of IBM mainframe
designs...I can't help but 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.
The embedded market is a completely different game. ;)
