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.

• Images are just for illustration - see the item descriptions for the exact type. 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.

New internal reset switch for Spectrum+ or Toastrack 128

• Brand new
• Same as original reset switch but has a light grey plunger instead of brown/black (Note: if you have an original reset switch that has gone bad, you can actually swap the plunger to the new switch body - it's fiddly though and care must be taken to avoid breaking anything.)
• For Spectrum+ and Toastrack 128
