Summary: More QM-1 remembrances...

	From what I can recall, the QM-1 had comparatively little serial
I/O support (at least using any Nanodata hardware).  I suppose that any
intended "large scale" serial I/O would be handled by a 360/370 channel
attachment to say, a 3704/5.

	I couldn't even begin to guess, especially in view of the above.
UNIX drivers for a 3704/5?!

	What always amazed me was that the lights were NOT labeled!
Perhaps there was a template or guide somewhere, but I never saw one.
I have seen QM-1's that had the lights spell out ``QM-1'' when the CPU
was in a wait state (I don't know what emulation or O/S was being run to
create that pattern, though).

	From the size and rating of the power supply, I would guess that
the CPU cabinet alone dissipated 3 KW of heat.  That'll keep you warm...
