In 1989, Unisys launched the Micro A, the first desktop single-chip mainframe system. The computer integrated the 48-bit SCAMP semiconductor chip (Single Chip A-series Mainframe Processor), which carried more than 10 million transistors. The processor was initially released as the A1 model, and was followed up with the A4 and A6 in 1990. The design included a host CPU, for which Unisys used a 16 MHz Intel 386 processor, surrounded by ten SRAM chips with a total of 12 MB capacity. The A1 also used an Intel 286 co-processor. It was the first time that a high-end server system was convincingly designed for a desktop space. The price tag: Unisys wanted at least $25,000 for an A1 system. 16 years later, a few people who had left low-power processor pioneer Transmeta attempted to succeed with a similar concept by squeezing 96 Transmeta Crusoe/Efficeon processors into a deskside supercomputer. The company, Orion Multisystems, went bankrupt in 2006.
