Overview
The HP 9000 A-Class A180 and A180C were among the last 32-bit PA-RISC HP 9000 800 servers, in a small and rack-mountable case.
Designated Enterprise Internet Servers
they were geared towards deployment in rack-space in datacenters and thus do not have video output, only serial console and a web console.
System design was pretty pared down and streamlined, with a simplified 32-bit PA-RISC design not dissimilar to the HP Visualize B180L workstation, minus the graphics and a few of the I/O devices.

System
Processor
- A180: PA-7300LC 180 MHz with 64/64 KB on-chip I/D L1 cache
- A180C: PA-7300LC 180 MHz with 64/64 KB on-chip I/D L1 and 1 MB off-chip L2 cache
The additional 1 MB L2 cache is the only difference between both systems. It was upgradeable through two DIMM slots near the CPU.
Chipset
