Just so you know, you can boot an Osborne 1 from the B: drive by
pressing <SHIFT>" (shift and double-quote) instead of <RETURN>.

  Hey Jules,
 Ah, so your O1 also has the weird screen artifacts prior to hitting
 'return'? Weird.. wonder what's up with that?
 I've only detected activity from drive A (LH side). It definitely does
 spin, the LED lights up, but I haven't been able to detect any head
 movement. You mention that the head on yours steps back & forth
 (indefinitely?)  with no disk present - does it behave any differently when
 the drive door is open vs. closed?
