Tadpole Computer was a manufacturer of rugged, military specification, UNIX workstations, thin client laptops and lightweight servers.

Originally based in Cambridge, England, then for a time in Cupertino, California, Tadpole was acquired by General Dynamics in 2005. Production continued until March 2013 but since then, they no longer sell any systems; and support for their products is provided by Flextronics.

Tadpole laptops were unusual in being based on SPARC, Alpha and PowerPC, rather than the more common x86-based microprocessors. Although very expensive, these classic Tadpoles won favour as a method to show corporation's proprietary software (IBM/HP/DEC) on a self-contained portable device on a client site in the days before remote connectivity.

SPARC

The original SPARCbook1 was introduced in 1992 with 8â€"32 MB RAM and a 25 MHz processor. It was followed by several further SPARCbooks, Ultrabooks - and the Voyager IIi. These all ran the SunOS or Solaris operating systems.

DEC Alpha

An Alpha-based laptop, the ALPHAbook 1, was announced on 4 December 1995 and became available in 1996. The Alphabook 1 was manufactured in Cambridge, England. It used an Alpha 21066A microprocessor specified for a maximum clock frequency of 233 MHz. The laptop used the OpenVMS operating system.

IBM PowerPC

A PowerPC-based laptop was also produced - the IBM RISC System/6000 N40 Notebook Workstation, powered by a 50MHz PowerPC 601 and with between 16 and 64MB RAM - and designed to run IBM AIX.

x86-based

Tadpole also produced range of x86-based, including the TALIN laptops with SUSE Linux, or optionally Microsoft Windows.
