You must put the terminator in, even on a single drive system. I've had problems
where you get glitches on unterminated lines and the drive can end up writing
when it shouldn't. Don't ask...

The M930 and BC11 should be easy to find, they are actually the same as the bits
used on PDP11 Unibus connections.
