Sinclair Project 80 (Z40)

Brand: Sinclair

The Sinclair Project 80 was a prototype computer developed by Sir Clive Sinclair's company, Sinclair Research, in the early 1980s. It was also known as the Z40 due to its Z80 CPU. The Project 80 was a response to the Cambridge Computer Lab's Acorn Atom, which was also based on the Z80 processor. The Project 80 was designed to be more flexible and expandable than the Atom, as well as cheaper. It used the same MOS Technology 6522 VIA chip as the Atom, but with better interrupt handling.The Project 80 had a small form factor, with a one-piece design that included a keyboard, and its case also doubled as a stand. It featured 16 KB of RAM, which could be expanded to 64 KB using SIMM modules.The Project 80 was intended to be used for ophthalmic laser measurement and mapping, but due to its high price and limited production run, it never gained widespread commercial success. However, its design influenced later Sinclair computers, including the ZX Spectrum and the Sinclair QL.Overall, the Sinclair Project 80 was an interesting prototype that showcased Sinclair's innovative spirit and design expertise, but it failed to make an impact in the market due to its niche application and high cost.
