4.46 RDI PrecisionBook
4.46.1 Overview
The PrecisionBook portable workstations from RDI (Tadpole)
219
are essentially C132L/C160Ls in a
laptop case. The PrecisionBooks mostly use the same technology as the HP 9000 workstations with
only slight differences. A major addition to the desktop cousins is the integrated Cardbus controller
for which Tadpole supplied a driver kit for use in HP-UX. Support for actual Cardbus and PCMCIA
devices in these slots was very sparse however (NE2000-based Ethernet as an example). OpenBSD fully
supports the Cardbus controller and a range of different Cardbus and PCMCIA devices (Fast-Ethernet,
WLAN etc.).
The PrecisionBook laptop case was used for other RDI RISC laptops as well, for example their Ultra-
SPARC systems.
Introduced in 1998 for a list price of $14,995 (180MHz version).
