After spending an entire day trying to get two new RD54's to format (one had
the switch, the other didn't), I cannot recommend running the RQDX03 with any
of those write-protect/ready switches missing.  With out the switch the control
line floats and you cannot trust the drive controler to write to any of the
disks on the system.  Having just one of the four switches on my system
missing, messed up my whole controler.  There is no good way to tie the line
high or low without the switch.
