Sophie Wilson FRS is a British computer scientist. She is known for designing the Acorn Micro-Computer, the first of a long line of computers sold by Acorn Computers Ltd, as well as the instruction set of the ARM processor. Wilson now works at semiconductor giant Broadcom, working on a processor line she also created - FirePath, a DSL chip that has also had a major impact.
Acorn Computer BBC Model A / B / B+ The Acorn BBC model A was the successor of the Acorn Atom and its first name was Acorn Proton. It was a very popular computer in the UK and was widely used in schools, but it didn't have great success elsewhere (even though it did have great features, it was too expensive). The Model A lacked some of the connectors of the Model B/B+ (User port, Tube, ...) on the underside.
Acorn Computer ATOM The Acorn Atom was the ancestor of the BBC computers series. It was sold in kit or ready-assembled versions. The great advantage of the Atom compared to its competitors (TRS-80 & PET), was its high resolution capabilities (256 x 192) which were quite unusual in 1979 for the price.
Acorn System 1. This 6502 modular system was the first computer produced by Acorn in 1979. It was basically the same type of computer as competitors offered at that time (KIM-1, MK14, Nascom, etc...) : a 6502 or Z80 CPU (in this case, a 6502) mounted on a simple "naked" board, with a one-line display and a hexadecimal keyboard.
