Hello all,
I am currently trying to work on what "should" be (or at least what I thought would be) a simple project involving a fountain gaming console (a radofin/acetronic/haminex compatible console from the 70s/80s).
Currently I am trying to create a homebrew cartridge of sorts that contains an eeprom that I can program with other games/my own creations.
For the base I am using a 2kb cartridge that contained a 9316B rom and I have replaced it with an at28c16 eeprom. I have successfully written to the eeprom using an arduino but for the life of me I can't get it to work. I have seen various sources quoting that the 9316B and 2716 are pin compatible (hence the 2816 should be too right?) and others saying pins 18 and 21 need to be swapped. I have tried both of these layouts and had no success.
Any insights/suggestions would be greatly appreciated. I am really at a loss as to why I can't get it to work.
Cheers.
