Replacement motherboards for the 48K ZX Spectrum

All boards have been carefully refurbished by myself, cleaned and tested thoroughly for several hours. Tests include load from tape, keyboard input, speaker, RAM, ROM, Z80 M1 signal and a 2-hour soak-test.

Notes: Images are just for illustration - see the item descriptions for the exact type. No boards come with a reset switch attached by default - if you need one for the Plus case (and there's some in stock) please add one to your cart and ask me (in the Special Instructions box during checkout) to solder it on before dispatch (no charge for that:)
