It has nothing to do with the power supply.  The supply does 1 Meg of
ram + the external drive fine.

What you are discovering is that the reset line for the printer port
is common with the disk.  While off, the printer is loading this in a
manner your ProDrive finds objectionable.  This may be the fault of
the printer... but I would suspect the design of the ProDrive.
