Software Support
OS help desk & break/fix
Kernel-level support for the operating systems that keep your business running - around the clock, from engineers who have worked these platforms for decades.
MPE/iX · The clock ticks on
For four decades, Allegro Consultants has kept mission-critical HP 3000 and HP-UX systems running non-stop - and we're built to keep them running for decades to come.
Excellence in OS support · Non-stop since 1974 · No end-of-life here
Flagship hardware · MPE/iX · HP-UX
Devices on Demand drops into your SCSI port and emulates every HP-supported tape drive, C1537A, DLT, and LTO, with a virtual tape library that holds hundreds of tapes on a single SD card. Every dead or dying drive on your shelf, replaced by one small box.

Bus powered · No cord · Runs off an SD card · MPE/iX · HP-UX · Linux
A note on ownership
For forty years, Allegro Consultants has kept mission-critical HP 3000/MPE/iX and HP-UX systems running long after their makers moved on.
As Donna Hofmeister begins a well-earned retirement, that mission continues without interruption. Allegro's support operations, products, and deep systems expertise are now managed by Craig Lalley and EchoServ, LLC.
Same systems knowledge. Same responsive support. New stewardship.
- Craig Lalley, EchoServ, LLC
