Yes.. I tried 7 bits.. different parity settings, speeds etc. Couldn't quite
nail it down. In every tutorial online for the 6800 being used with PC
terminal, they go 8 N 1.. nobody mentions specifically if you are supposed to
use hardware or xo/off or nothing though. So that's another thing. I'm also
confused because some docs mention baud rate settings for the cpu board?
I'm also not sure if bad RAM or bad TTL etc could be contributing to just
throwing out random junk too.

"Random Stuff" on serial ports can be a speed, data-bits, or even parity
mis-match.
I assume you have tried tweaking these?
