ZX Spectrum – U-075778



  • Serial Number: U-075778
  • Memory: 128K (untested)
  • Issue: +2 (Grey)
  • ULA: Covered by a heat ‘sink’
  • Z80: Z8400APS (8622) (assuming that’s the right chip)
  • Cost: £0.99 (eBay)
  • Comments: UHF modulator is damaged, but the composite output from the 8pin DIN socket appears to be reasonable, rest of the device looks in good working order.


  • 6/10/2012 – Have built a cable to get the composite working, considering modifying the main board to reverse a transistor which should clean the composite up even further.
