Since the 1980s, Racine Water & Wastewater Utilities relied on an HP 3000 A-400 with MPE/iX 6.5 as their primary billing system. When they moved to a new platform in 2008, only four years of history carried over to the new system.
The HP 3000 still held more than 25 years of important records. The state of Wisconsin mandates access to billing history records, and they needed a way to continue using the HP 3000 to access archived information. That’s when they considered HP 3000 emulation.
After contacting Stromasys for the job and in the early stages of demoing a Charon solution, one of the system’s disk drives stopped working. In this case, the only method to recover the system’s data was from old DDS1 backup tape, although this appeared to be missing from the legacy system.
For this, Stromasys purchased a DDS1 tape drive for the data recovery and, utilizing Oracle Box, built a virtual machine and recovered the HP 3000 system.
Once the data was safely retrieved, the Stromasys engineer working with Racine Water implemented CHARON-HPA/A408 as the virtualized HP 3000 environment. Now, the original hardware has been replaced with a PC that runs the legacy applications on Charon software, exactly as they did on the original hardware.
