Sure, but you'll need something running on the box to talk to the terminal..
I do know that the BCS/SIO/Paper Tape stuff on Jeff's site will talk to
the buffered TTY interface, but don't know about the HS card...

Yes. The slots are numbered, from 10B to 25B (In a 2100 anyway, the MX
may have more slots, but I don't thinks so... The B means Octal...) The
highest priority slot is 10B, and you won't want any empty slots between cards
or between 10B and the first card...
On Jeff's site, look at:
http://oscar.taurus.com/~jeff/2100/2100ref/index.html
The 21MX is a "bigger,better" 2100 (it has additonal instructions)
but the IO system is quite similar...
