Acorn BBC Micro Model B
RH-E9DB
The machine the BBC's Computer Literacy Project was built around, and so the one a generation of British children learned on. Acorn's engineering is the draw: a 6502 clocked properly, four-channel sound, seven display modes and an expansion bus that made it the standard laboratory and school controller for a decade. Collectors watch for the Ferranti ULAs, which fail and take the display with them, and for the 8271 floppy controller of an early board.
