Yeah, I was hoping that someone had a base unit that had a chip instead of a glob. The one I was sent had a glob, and the test pins weren't bonded out, so I couldn't experiment with them.
Oh, I see... I'll check mine when I get them out of storage. I know one is a glob, but I have two of them... They are probably all the same though.
Mappy is definitely not Sharp SM5. And there is some tricky routing under the glob (4 signals at the bottom are routed up to the top).
Shark Island is obviously a Toshiba 43381. I have another Tandy game with that chip, but I haven't done anything with it yet.
Space-N-Counter sure looks like a Sharp SM5, but the designer's web page makes it sound like it's a Toshiba chip. If it is a Sharp, it would have to be deglobbed to dump it visually; there aren't enough pins bonded out to dump it electronically.
I can donate them all, so if you want to deglob them and see what can be done, that's fine by me.
