The ZX81 Museum was set-up to preserve and showcase original Sinclair-branded ZX81 hardware, software and literature. The museum has since expanded to include ZX81 software from other publishers of the time and a variety of ZX81 programming and reference books. The collection dates from 1981 to 1983 and features the complete Sinclair-branded software series.
