The HP 9000/745i and 747i were VME PA-RISC workstations from HP, released in 1992 for industrial control and medical use. They are technically close to the HP 9000 715 and 725 workstations but integrated into (19") rack-mountable cases. They run standard PA-RISC Unix operating systems.

The CPU and I/O controllers are an integrated VME single board computer (SBC) like the 742i VME board, identical in both 745i and 747i. The 747i are built into a bigger case with several VME expansions slots for devices, the 745i has none.

Both 745i and 747i have a HP-IB interface used for controlling, measurements and instrumentation devices. These machines have two pairs of LED banks, one at the front and the other directly on the CPU board on the back.

There were the similarly named HP 9000 745 successors (745 without »i«) that were based on a newer hardware platform and PA-7300LC processors, basically in the same case/form-factor.

HP 74x VME products were discontinued in 2002 as customers have migrated to new solutions and platforms more rapidly than anticipated with end of support between 2003 and 2007.

Model Introduced Price
745i/50 1992 $13,390
745i/100 1992
747i/50 1992 $15,990
747i/100 1992

Six years after the 745i, HP released the similar 745/132L and 745/165L VME workstations with new technology and PA-7300LC processors.
