24-6-2026: HEATWAVE ALERT: The store will be closed for a few days due to the extreme temperatures ATM (will post existing orders today). I'll be back at the weekend when hopefully things will have cooled down! Cheers, Phil.

Spectrum 128 +2 Motherboard Iss1

Spectrum 128 +2 Motherboard - Issue 1

Re-capped (with new blue axial electrolytic capacitors) and modded as follows:

  • Installed beeper/AY balance mod resistors (to better balance the mixing of the various sound sources)
  • Installed TEA2000 RF/Composite video mod (inductor+cap) to reduce the cyan/yellow cast on RF/Composite output
  • Performed sound mod (RF sound injection point re-directed to TR1)

Full working order, tests included:

  • Keyboard and joystick inputs
  • Tape load input
  • Reset button
  • RGB, Composite and RF outputs (note: RF was never amazing on these machines but is as good as it really gets here - Composite or RGB output is definitely recommended).
  • Diagnostics via external cartridge etc (including RAM, CPU /M1 line, AY sound etc)

Note: Only the mainboard is supplied (no voltage regulator, heatsink or tape parts)

Price: £ 59.99   Add to cart. (2 in stock)
