Tadpole Technology Plc has now added Digital Equipment Corp and its Alpha AXP to its list of RISC conquests, and is to develop the first portable notebook workstation to run Windows NT as well as Unix. DEC has retained the Cambridge, UK company to develop – with DEC’s assistance – a notebook computer based on the Alpha AXP DECchip 21066 RISC microprocessor. Tadpole won its spurs with its Sparcbook family and has also developed a PowerPC 601-based ES/6000 notebook for IBM Corp. That drains the battery in only 40 minutes, so Tadpole is working on a version using the low power consumption PowerPC 603 part.
