Description

HP A4091A 715/100 PA-RISC Workstation 128MB RAM 3.5 FDD A2084A HP 9000 HP-UX

The HP 715/100 is a PA-RISC-based UNIX workstation from Hewlett-Packard's HP 9000 700 series, built around the 100 MHz PA-7100LC processor. The 700 series represented HP's high-performance technical workstation line of the early-to-mid 1990s, designed to run HP-UX and serve engineers, scientists, and CAD/CAM users. This unit (Product # A4091A, Base Product # A2084A) powers on and reaches the BootRom 1.4 screen with 128 MB of RAM recognized. It is being sold AS-IS due to several known issues — see condition block below.

Applications

The HP 9000 700 series workstations were the dominant PA-RISC desktop platform throughout the early to mid-1990s, running HP-UX and serving as primary workstations for engineers, electronic design automation (EDA), mechanical CAD, scientific simulation, and software development in technical and research environments. The 715 line was HP's entry-to-mid-range offering within the 700 series, targeting cost-conscious technical users who still needed a full PA-RISC UNIX environment. These machines supported a wide range of HP-UX software stacks including tools from HP, Oracle, and various EDA vendors. Today the HP 9000 715 series is sought by vintage UNIX collectors, PA-RISC enthusiasts, retrocomputing hobbyists, and those maintaining legacy HP-UX environments — particularly software developers and researchers preserving period-accurate computing setups from that era.

Condition: For Parts or Not Working
This HP 715/100 PA-RISC Workstation (A4091A) is being sold AS-IS for parts or repair. It cannot be fully tested — we do not have a compatible HP keyboard, and without one the machine halts at the BootRom screen with a "Failed to initialize a keyboard" error (BootRom Version 1.4, Memory Size: 128 MB confirmed on screen). Additionally, the video output was observed to be unsteady — colors flickered and the image changed size during our testing. The case lock latch does not appear to be functioning, and the chassis shows general cosmetic wear consistent with age and prior use. There is no hard drive installed. This unit is not guaranteed functional and is sold strictly as-is. Please view our photo set and contact us if you have any questions.
