Amstrad ZX Spectrum +2B

Sinclair ZX · 1988

The last Spectrum. A +2A with the power and video circuitry revised after Amstrad moved production, and the final machine to carry the name before the line was discontinued in 1990. Externally identical to a +2A, so the board markings are the only way to be sure which one is in front of you. The end of eight years and five million machines.
