retrocomputing

Paul Flo Williams' annotated disassembly of the DEC VT100 terminal's firmware is circulating again among retrocomputing enthusiasts. The project documents the 1978 terminal's 8080 assembly code in detail, explaining how DEC implemented its control sequences and character rendering. Readers are revisiting it as a well-preserved example of early hardware-software co-design, and it remains a key reference for anyone studying classic computer terminals.
