One of the most reliable pieces of computer equipment ever produced is the HP-1000 Mini-Computer made by Hewlett-Packard from the early 1970's through the late 1980's.

The system, with its Real-Time Executive operating system was a standard fixture in laboratories and factories all over the world.  Even today, there are still major manufacturing plants which rely on it for process control and data acquisition.

Joe Mellem began programming the HP-1000 in 1977 for the Chevrolet Technical Center in Warren, Michigan.  It was a leap in technology from the punch-card systems being taught in colleges and universities, yet it was a far cry from later versions to come.

The RTE operating system matured and expanded in functionality until H-P decided to retire it and direct their resources toward Unix and their Precision Architecture processors.  But, it was not easy to replace the HP-1000 Series.  Partly because of its processing and I/O capabilities but, mainly due to the RTE operating system.  The level of consistent, deterministic repeatability of processes running under its control was much more difficult to replace than H-P expected.  The transition to what was billed as "Real-Time Unix" was a failure and support for the HP-1000 was extended several times.

Joe Mellem has extensive programming and configuration background with the HP-1000 and RTE, from the earliest versions which used core memory and paper-tape, to the end-of-life hardware and RTE-A operations system.

We have been successful in upgrading earlier models to the A-Series, as well as, integrating them with modern PC's and Unix servers.
