Tadpole Computer was a manufacturer of rugged, military specification UNIX workstations, thin client laptops, and lightweight servers.
History Tadpole was founded in 1994 and originally based in Cambridge, England, then for a time in Cupertino, California.
In 1998, Tadpole acquired RDI Computer Corporation of Carlsbad, California, who produced the competing Britelite and Powerlite portable SPARC-based systems, for $6 million.
Tadpole was later acquired by defense contractor General Dynamics, in April 2005.
Production continued until March 2013 but since then, they no longer sell any systems; and support for their products was provided by Flextronics. Flextronics discontinued Tadpole support around 2019. Vector Data, a Tadpole OEM, still provides legacy Tadpole systems and support.
An anonymous US intelligence officer had stated to Reuters in 2013 that a decade earlier the US secretly created a company reselling laptops from Tadpole Computer to Asian governments. The reseller added secret software that allowed intelligence analysts to access the machines remotely.
Products Tadpole laptops used a variety of architectures, such as SPARC, Alpha, PowerPC and x86. 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.

The SPARCLE was based on a 500-600 MHz UltraSPARC IIe or 1 GHz UltraSPARC IIIi.
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.HP OpenVMS Systems Documentation Retrieved September 15, 2011.
IBM PowerPC
A PowerPC-based laptop was also produced – the IBM RISC System/6000 N40 Notebook Workstation, powered by a 50 MHz PowerPC 601 and with between 16 and 64MB RAM – and designed to run IBM AIX."IBM RISC System/6000 N40 Notebook Workstation", March 8, 1994, Announcement Number: 194-062
