Find a37c65 or 9266. no big deal using raw ttl as then  you can do ANY 
data rate.

Not required.  Small system, nice addition but pumps up complexity 
more than a bit. 

most of the S100 CP/M systems (and some of the SBCs) are non DMA and 
not even interrupts for serial IO.  All polled.  Not as nice but 
hardly serious.

Fix it, build one or find a VT220,320,320 whatever.

myself I plan to buld a subsystem terminal but for the time being a 
VT320 or a DEC VK170 for those that know what that is.
