(MESS) DEC Rainbow updates: [M. Burke, R. Belmont]
- LK201 keyboard matrix hooked up and working
- LK201 serial I/O first pass


(nw part)
diserial is currently misframing the input bits so the LK201 doesn't get the proper commands from the Rainbow.  If someone with experience in this area is bored, I won't be able to look at this again for about a week.  The LK201 also needs a devcb2 hookup for the send back to the system once things are resolved.
