RDI PrecisionBooks are portable PA-RISC workstations, introduced in 1998 by RDI, shortly before the takeover by Tadpole. The PrecisionBooks are based HP 9000 C132L/C160L workstation technology integrated into a portable case, geared towards engineering, software development, network management, financial modeling, military command operations, and intelligence gathering.

RDI PrecisionBooks were technically equivalent to C132L/C160Ls and 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 a driver kit for HP-UX.

The RDI PrecisionBooks apparently did not enjoy large commercial success. The PrecisionBook laptop case was used for other RISC laptops as well, for example the UltraSPARC-based Tadpole Ultrabook that was supposedly 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 based on their own design.

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.).
