Mamlas_CPLD - how to make ZX SPECTRUM_48  a ZX SPECTRUM_128 compatible computer ? How to repair within few minutes ? 

 

 

 

September 2024: 

  • CPLD was replaced with FPGA
  • minor changes to PCB
  • added compoiste video output.

 

MAMLAS_FPGA  is my next step to help ZX Spectrum owners  to repair their computers home, as in most of the cases  faulty is dynamic ram... or ULA, CPU, ROM... etc.... 

  • mounted under Z80 CPU 
  • additional adapter mounted in place of ULA (4 wires connection to main board)
  • replaces  ULA, RAM, ROM
  • adds 128-512KB of ram
  • FPGA based
  • 2 modes: ZX128, Penatgon
  • Turbosund (2 x AY, 4 x covox) 
  • RGB video output 
  • compoiste video output
  • ULA adapter:
    • port FE - keyboard, ula sound
    • IOREQ , CPU_CLK/INT  signals ..
