  1. thansk for your response although: i have both a 24 pin socketed pcb and a 28 pin socketed pcb, so will my orginal idea of #'s 1 and 4 work? thanks.
  2. Hey guys I'm new to this and have a couple of questions. I have an eeprom burner. I have the PCB I got from atariage. I want to backup some broken carts (the roms) new newer chips. 1. Can I use EEPROM instead of EPROM? (provided the specs are all the same) 2. What speed (E)EPROMs do i need, wil 150-200ns work? 3. What operating voltage? (5V)? 4. Also I know you have to double up a 2K rom to fit on a 4K chip, but can i say double up a 16K to fit on a 32K or quad an 8K to fit on a 32K or ever build a 2K into a 32K? The reason I am asking is because i only really want to buy on type of chip cuz it will be cheeper to buy a lot of the same type. (planning on 27256, 27256A, or 27C256. Thanks for all your help, I want to learn how to code my own games too, it seems like fun.
