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 inputs, speaker, RAM, ROM, Z80 M1 signal and a 2-hour soak-test.

  • Images are just for general illustration and do not show the actual boards in stock - see the item descriptions for the exact specifications.
  •  If you need a reset switch for the Plus case (and there's some in stock) please add one to your cart and - if you wish - ask me (in the Special Instructions box during checkout) to solder it on before dispatch - no charge for that:)
  • Some boards are sold without ULA chips - please see the individual item descriptions. 
  • Unless stated, the Issue 4S boards will not have been recapped as the original high quality Samwa brand caps are still pefectly fine.
