Some enhancements for the Sinclair ZX Spectrum 48k

After many years i have decided to made some improvements to my Sinclair ZX Spectrum 48k Issue 2.

Below what has been done:

  • Replaced the obsolete 7805 voltage regulator with a modern and performant one that heats up much less; the TRACO Power 2450 (DC / DC Converter)
  • Replaced the ULA Ferranti with a fully compatible FPGA solution (vLA82 designed and created by Charlie Ingley). Again it does not heat anything.
  • Replacement of all electrolytic capacitors.
  • Rework of an old Composite MOD with a more performing one.
  • Replaced the Membrane and the bioadhesive to fix the keyboard with hard keys.

    Hi

    Can you provide some more information on the fitting of the Traco power 2450, I have an issue 3 board and was wondering if this would work.
