32K Supercart
#3
Exactly, Steve. The board had enough space to put both chips (32Kx8 and E/A GROM) in positions that didn't interfere with the case or the battery holder. I'm still trying to figure out if there is enough real estate available in the right area to switch out the resistor/diode matrix for the battery with an 8-pin DIP that does an even better job at switchovers, but it may be a bridge too far on this one due to space limitations. The battery holder and the 32K chip each chew up a lot of space in that part of the cartridge case. I could probably do it by not socketing the 8-pin chip (a DS1210), but I am a bit loathe to go that route.
Enter my mind at your own risk!
