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.
