Here are a couple scans from my recently acquired high score cart as well as a comparison with the earlier wire wrap version. The ROM dump is also different. Unfortunately the original EPROM cover is missing so the date and version are unknown.
If anyone else has one please post some pics. I know two more were sold recently.
Curt also has a pic of his high score cart on his website. http://www.atarimuse...00/hsc/hsc.html
