Storms Corner website has caught my attention with some ambitions projects like this SK-1 Rom bank mod. The builder went as far as rigging up a flash rom IC and dumping the original rom to it with some modifications. Unfortunately no sound was made, so technology is not all there yet. The most useful thing from the website however is the link to the SK-1 service manual pdf and the JPEG version , which is insane! So check it out and huge props to Storms for the neat ideas.
