This is one of a series of computers from the long running Alpha Micro Company (1977-2018) They were usually inexpensive systems that could initially handle 1-24 terminals, but in the 1980s could take up to 60.

They used the AMOS operating system (Alpha Micro Operating System) This had many similarities with the DECsystem10, and as a result, DEC tried to sue Alpha Micro unsuccessfully in 1984. This operating system was a multi user, multi tasking time sharing program, and the machines were S100 compatible until the early 1980s, when they became based around the 68000 16 bit processor line.

This particular machine was one of the first into the country from the US. It has a complete set of manuals for AMOS. And was bought by a gentleman who owned a systems house for an accounting and freight forwarding software company,  it has a 100L processor, and uses  VHS video tapes for backup. It is configured for 10 terminals.

This machine was supplied to the owner by IMS (Integer Microsystems Ltd) of Colchester, near to where we collected it from.

Donated with the kind generosity of Belinda Freeman.
