ok now using 2 62256 ram game load play nice but thant crash or sound bug
probably because the breadbord but if someone have an idea ???
i ordered a 64k chip to replace the 32k should do hope so
5-11 can i have your opignion please
Of course your Colecovision will crash!!!
In the memory space there is space only for 24K of RAM, so you need only one 62256 (32K RAM)
To reduce noise put a bypass capacitor 0.1 mf between VCC and GND of RAM, so short as possible.
To test the memory use this little program I wrote for Super Game Module: http://atariage.com/...m/#entry2748035
