 HP VME Single board computers are amongst the most rugged and widely used today in civil aviation and military applications. Its 6U form factor has provided the flexibility required by engineers. The model 744/165L PA-RISC 7300LC board computer uses the standard HP-UX 10.20 or later operating systems, including HP-RT, a highly versatile system for multi-tasking, running your application programs and performing a variety of development tasks.

VME Repair Program

Alimar Technology also offers a HP VME Board repair program. Boards that are deemed defective for a variety of reasons can be tested and troubleshoot on a per board, or contract basis. Currently we have had a 90% success rate in repairing graphic & terminal features on 743 & 744 boards. 

Basic fees do apply to the process.

Generally a 'bench fee' is charged regardless of the work performed. If the board is un-repairable you are only charged the bench fee. If the board is indeed repairable the bench fee is waived and you will be charged according to the work that has been performed.

There are no set prices, as the level of repair varies from board to board.

We have on occasion had to rework boards that had been 'repaired' by others and the people who perform our repairs take great personal pride in their abilities, which enable us to return boards in a equivalent to new condition.

Such repairs are conducted in a clean room environment with the industry standard ESD & enviornmental protections.

If you are interested in having a board repaired or quoted, please contact or contact him by phone (603) 679-2990
