Hello,
I am trying to repair a Movit2 programmable cartridge. The problem of this cartridge is that data is not written to static RAM. ROM program works ok but F3 (erase data) don´t clear all the movements and some new ones appear. F2 (Charge data) seems to write the movements to static RAM but all data is lost when RESET or Power off.
Does anybody has schematics of this cartridge? Or, images of the pcb? There is a cut pcb track with a wire connected to 74LS04 chip.
Thank you very much
Oscar
