HP Visualize C160, C180 (C-Class)
|Cache||1-2 MB L1|
|Bandwidth||CPU/Mem 960 MB/s|
These HP Visualize C-Class workstations were graphics workstations equipped with the 64-bit PA-8000 processor. The C180 and C200 were the higher-end offerings with stronger CPUs and usually better configurations, as compared to older HP Visualize C100, C110, or lower-cost C132L, C160L. The case is similar to that of the HP 9000/735 workstation, built of interlocking modules. These machines were aimed at CAD/CAM/3D modelling.
The C180 is also sometimes referred to as C180XP
Model numbers: both the C160 and C180 have the HP 9000/780 model number.

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).
- 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
- EVC graphics port1
- Two PS/2 connectors for keyboard and mouse
- HP-HIL for input device loop
- Four phone jacks (microphone, headphones, line-in and ?)
- You need a special HP adapter-cable to convert this EVC-port to either BNC or VGA HD15
There is a firmware update available for the C160 and C180, which contains the latest version (6.2).
