The SCELBI (SCientic-ELectronics-BIology) was a micro-computer marketed toward individuals and hobbyist. The first version, the SCELBI 8H, was advertised in the April 1974 issue of QST magazine, making it the first practical computer marketed toward ordinary people. The design was based on the Intel 8008 micro-processor and supported 4K of SRAM memory. An improved version, the SCELBI-8B was released about a year later and included support for up to 16K of memory and optionally included a 4K EPROM board that supported a sophisticated (for the time) 8008 development environment called MEA (monitor, editor, assembler).
