Grey Matter E! Expansion for the Yamaha DX7II FD/D

"This is what a virgin Uninstalled E! board for the Dx7IIFD looks like. Boxed, booked and stickered. No magic special components, just plain old 74HC/CMOS glue logic, EPROMs and some memory ICs. We could clone it if we wanted to, I guess, although, there are a lot of smart cookies out there who would be able to do the whole thing on one chip nowadays without too much drama. Original installation guide was on blue paper, but, I've made it a big more screen friendly black and white, 'cause I'm such a facist like that sometimes'."
