The Tangerine Microtan 65 (sometimes abbreviated M65) was a 6502 based single board microcomputer first sold in 1979 which could be expanded into what was for its day a comprehensive and powerful system. The design became the basis for what later became the ORIC ATMOS and later computers which had similar keyboard addressing and tape I/O as in the Microtan 65. The Microtan 65 had a single step function that could be used for debugging at the hardware level.
