This is the black square version originally sold with the ZX Spectrum Plus, but is also compatible with original Spectrum computers (rubber keyed 48k and 16k) and the later Spectrum 128K and +2 (original grey model).
Unit only in very good, fully tested condition. Includes UK power plug.
Note this is an original 1983 Sinclair Power Supply - not a reproduction, but original vintage hardware tested on vintage computers.
