Hard Disk Drive
You can use a number of different hard disk drives in your PG 760 PII. The
memory capacity of the hard disk can be found in the Product Information

second drive can also be connected to this interface as a slave.
Whenever the hard disk drive is accessed, the access LED on the front of the unit
lights up.

(secondary IDE). A second drive can also be operated on this interface. If the
