The HP 9000 C100 and C110 are PA-RISC graphics workstations based on the PA-7200 processor and were introduced in 1995. They have a similar case to that of the old HP 9000 735 — built of interlocking modules of the I/O and MPU board.

The 32-bit C100 and C110 were board-upgradable to the 64-bit C160 and C180 for around $7,000 in 1996.

Storage

The disk slider can accomodate up to three SCSI drives and one floppy drive simultaneously, the internal cabling (usually) includes one Wide-SCSI cable with three 68-pin connectors and a HVD-terminator at the end, one Narrow-SCSI with one 50-pin connector and one cable for the floppy.

The Narrow-SCSI cable is normally used for the external-accessible half-height 5.25″ CD/DAT drive, although it is of course also possible to connect a 50-pin SE hard drive. The cable can also be easily replaced with a variant with more connectors to use up to three 50-pin SE hard drives. The PDC can boot off these SE drives.

The Wide-SCSI cable is normally used for the internal 3.5″ 68-pin Fast-Wide high-voltage differential system drives. Up to three hard drives can be installed in the cage, which leaves no room for an external-accessible CD/DAT drive though. The Fast-Wide drives are also bootable from the PDC.

A standard configuration could look like this:
