	Some drives contain low and/or high pass filters on the data
lines.  These filters prevent the Mac GCR data from getting to/from the
disk since it is in the wrong frequency range.  There may be a fix for
these drives, assuming you don't care about any warranty that is left on
them.  Details will be provided by Gadgets by Small when the GCR is
shipped *if* the modification proves to be reliable.

	The drive light should go on for at least a few seconds when the
Translator attempts to read a Mac disk.  If the drive isn't being
selected at all then there may be a problem with the Translator.  Try
using the Translator with another drive, a standard Atari drive would be
best, and also try the TRANSTST program.
