Apple 1 Repro with GI 2513 character generator

This reproduction board (image source: is using the GI 2513 character generator which is a +5 volt IC (instead of the original 2513 which used 3 voltages +5, -12, -5). The GI 2513 is a drop-in replacement for the old Signetics 2513. I have a handful of these chips if anyone needs one... drop me a mail (servobit AT maine DOT rr DOT com)
