I plan on removing the MCA bus support on or around Feb 15th. Please
let me know if you are running any of these devices on FreeBSD 10 or
newer.

This is a different MCA. That's Machine Check Architecture. I'm not
messing with that at all....

I'm talking about Micro Channel Architecture cards from the old ps/1
