ZX 48/48+ SRAM / CPU  MODULE  is my next step to help ZX Spectrum owners  to repair their computers home, as in most of the cases  faulty is dynamic ram and CPU

• replaces base CPU ram of 32KB 
• replaces Z80 CPU
• installation consists of 3 steps: 
• remove old rams 32kB
• remove old cpu
• solder module in place of CPU  or insert into socket (not supplied)
