Replacement motherboards for ZX Spectrum

The following boards have been refurbished and tested by myself, as follows:

  • Replaced original electrolytic capacitors with new ones.
  • Modded to output composite video signal - for best picture and compatibility with newer TVs.
  • Cleaned edge / tape connectors etc.
  • Tested on RAM-test loop for 2 hours
  • Loaded games from tape
  • Connected and tested expansion connector with SMART Card
  • Checked keyboard input


  • The thumbnail photos are generic images, for illustration only.
  • All boards have original Sinclair ULA chips.
  • If you'd like the board supplied with a reset switch soldered on and a heatsink attached to the ULA (IE: for use in a Spectrum Plus case) please buy the "Spectrum+ upgrade" item.

Replacement Sinclair ZX Spectrum Motherboard Issue 2

Sinclair Spectrum 48K Motherboard Issue 2

  • Re-capped and composite modded.
  • Note: Issue 2 boards are less suited to fitting in a Spectrum Plus case due to the size/position of the heatsink (the heatsink can be modified, or removed entirely if a switch-mode voltage regulator is fitted).
