Q1 Corporation in New York, owned by Daniel Alroy, was the first company to develop a complete, standalone, microcomputer system integrated with a screen and keyboard. It was introduced in 1973, based on the Intel 8008 processor.
The later version Q1 Lite from 1978 was widely sold in Europe, Holland, Germany, Denmark, Sweden, etc. and based on a Z80 processor, 2708 eproms etc. My version has the Swedish character eprom for the nordic/scandinavian letters (æ ø å etc.)
