It's fun to read this stuff. I didn't realize
microchannel was
available from anyone but IBM. And notice how it's MS(R) OS/2. :-)

Tandy wasn't the only other company making MCA machines. NCR made quite a
few different models. I believe Siemens made one or two as well.
And Apricot, who made the only non-IBM MCA boxes I personally ever worked on.
If there are any MCA collectors out there, I still have a whole pile
of cards I'm trying to give away... Free for the postage.
I'd love to have them, if only you weren't all the way over there.
