RISC Laptop Archive from the 1990s (updated)

Technical computing of the 1990s was the era of RISC workstations on Unix systems and applications. To extend that computing power to mobile users, quite a few traditional workstation vendors built RISC for the Road computers.

RISC Laptops of the 1990s is hosted by OpenPA, the PA-RISC reference. Find us in the OpenPA RSS feed and news.

RISC laptops were mostly based on contemporary Unix workstations designs and were marketed for government and military users for C3, analysis and surveillance (ISR) applications. There were quite a few designs marketed over the years.
