Note that for use on the HP 64000, the 9134A must have been built with 
Option 010.  That configures the drive as a single 4.8 MB unit.  The 
standard configuration 9134A appears to the host as four 1.15 MB volumes to 
emulate four 9895A floppy drives.

A sticker on the rear of the unit to the right of the serial plate should 
show "OPT. 10" if it's a single unit configuration.

(I have one of these and used it successfully on an HP 64000, but it is 
sloooow!)
