HP 9000 748i and 748 ruggedized PA-RISC workstations are HP 9000 743i and 744 VME boards built into a heavy VME case like the 747 with integrated I/O. The rugged VME cases were designed for durability and reliability in harsh environments and had built-in expansion options for six 6U VME slots for additional I/O boards, up to four SCSI devices and a four-slot EISA or PCI cage.

Model 748 was exceptionally flexible and responsive, based on 32-bit PA-RISC and compatible with other HP 9000 technology and applications.

Designed for instrumentation purposes, HP 9000 748, like the other HP PA-RISC VME computers, were often used in manufacturing, scientific but also military uses like ISR and targeting.

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.
