HP Visualize C160 and C180 were graphics workstations equipped with 64-bit PA-8000 processors, introduced in 1996. They were higher-end offerings with faster CPUs and better configurations compared to older HP Visualize C100, C110, or lower-cost C132L, C160L.
The case is similar to that of the HP 9000/735 workstation with interlocking modules. These machines were aimed at CAD/CAM/3D modelling and were succeeded by the powerful C200 and C240.
C160 and C180 were the first smaller 64-bit PA-RISC workstations for graphics applications and positioned by HP against Sun Ultra 2 and Silicon Graphics Indigo2 workstations for Unix technical computing.
HP marketed them for MDA, EDA, Exploration and Production, GIS, and Medical Imaging
as well as fluid dynamics and structural analysis
as they had outstanding floating point and graphics performance.
- HP Visualize C160, HP 9000/780, were introduced in 1996 for $24,000
- HP Visualize C180, HP 9000/780, were introduced in 1996 for $50,000
C180 were sometimes calleds C180-XP if a Visualize XP graphics adapter was included. 32-bit C100 and C110 were board-upgradable to C160 and C180.
