Does this mean setting input-device/output-device to tty? instead of
kbd/screen?

Interesting - I've been having problems booting from my 6400 (it boots as
long as its set to ttyb/ttyb but kbd/screen doesn't work).  How do you
make a COFF file and put it on a floppy?  Or even better, what is a COFF
file?

Yeah, me too. :(

So it looks like the 6400s are suffering from the same problems as the
C600s.  Very interesting.  Are there any patches/fixes/workarounds to
these problems that anyone knows of?
