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:
- Two 3.5″ 68-pin Fast-Wide differential (HVD) SCSI hard drives,
- One 3.5″ Floppy drive and
- One external-accessible half-height 5.25″ SCSI drive (CD/DAT).
External ports
- SCSI-2 50-pin single-ended
- SCSI-3 68-pin Fast-Wide differential (HVD)
- Two serial RS232C DB9 (up 460.8Kb/s)
- Parallel DB25
- Ethernet RJ45
- Ethernet AUI 15-pin
- Graphics port depend on installed video adapter
- Two PS/2 connectors for keyboard and mouse
- HP-HIL for input device loop
- Four phone jacks (microphone, headphones, line-in and ?)
