The 9133 (hard + 3.5" floppy), 9134 (hard only), and 9135 (hard + 5.25" 
floppy) used the same controller, so the floppy address switches on the 
9134 don't do anything.  They're active on the other two models.

Although you may already know it, it's probably worth mentioning that the 
64000 system hard disc must be at address 0, a system line printer must be 
at address 1, stations must be at 2-7, and one of the stations (or the only 
one) must have the rear-panel master/slave switches set to "master," 
according to the 64000 configuration guide.
