RDI PrecisionBooks are portable PA-RISC workstations, released by RDI in 1998, shortly before the takeover by Tadpole. They were based on HP 9000 C132L workstations in a portable case and marketed as first HP-UX laptops.

PrecisionBooks were used for engineering, software development, network management, financial modeling, military command operations, and intelligence gathering.

As RDI PrecisionBooks were technically based on C132L/C160Ls, they supported the same PA-RISC operating systems and applications. A major addition by RDI to the system logic was an integrated Cardbus controller for which Tadpole supplied drivers for HP-UX.

RDI PrecisionBooks apparently did not enjoy large commercial success but Tadpole reused the laptop design for other RISC laptops of the 1990s, for example the UltraSPARC-based Tadpole UltraBook that was slightly more successful.

In addition to the PrecisionBook, only two other portable PA-RISC computers were produced – the military-focused SAIC Galaxy 1100, based on HP 9000 712, and the Japanese Hitachi 3050RX 100C laptop, based on Hitachi custom design.

There were a few other RISC Laptops in the 1990s, with a wide variety of processor architectures such as SPARC, PowerPC and even Alpha.

Operating systems

Not all devices or expansion options and modules are supported in Linux and the BSDs. OpenBSD fully supports the Cardbus controller and a range of different Cardbus and PCMCIA devices (Fast-Ethernet, WLAN etc.).
