Amiga DRAM chip tester for HYB-514256B with Arduino UNO - Amiga 500/500+
 

I made an arduino project that tests the Amiga 500 and 500+ memory chips
It is open source and not complete. I dont have plenty of time and I am not experienced with the way dram works, so If anyone can contribute or can help in any way it will be nice:
