> > could you make some sort of schematic on how to wire up sockets to the proper pins on a cart's edge connector? I'm especially interested in 16 and 32 mbit games.. I know 8 mbit are possible using 2 27c4001 eproms in parallel without any extra electronics. would 16+ mbit require extra electronics?

the 27c8001 has a 1024x8 configuration and is available as normal DIP32, as far as I know, so that shouldn't be a problem.

I'd appreciate that.
