     The XLR8er can be installed with a cable up to six inches long, so
it probably should be long enough to move it out of the way.  As for power
supply loading, there shouldn't be any problem.  The whole XLR8er board
pulls power on the order of what the Z80 it replaces does.  This is due
to the fact that the HD64180 is a CMOS device.  RAM, therefore, is the
only thing left that pulls power of any significance.
