Right.  I am saying don't make a permanent hardware change to a 1541 that
does not have the switches unless you really want it to be permanent
because there is a software method of assigning drives that is good enough
most of the time.  BUT if you must make it permanent and you don't have the
external switches, consider adding some form of external switch so you
don't ever have to open the case again to put it back to the default.  Less
likely to burn traces, etc if you can avoid working on the same circuit
more than once.
