  1. the schematics says "2600 f8 bankswitching" is this circuit compatible with all f8 bankswitch? I'm looking for a circuit that is compatible with Parker brother games, will Montezumas Revenge work on this circuit? if not, can you tell me what kind of bankswitch I can use on it?
  2. thanks. And you know if I need to connect: /A1-A12 to 74133 inputs in order? for exemple, /A1 to pin 1, /A2 to pin2 A3 to pin3..... or it's not necessary?
  3. hey guys, need some extra help here. I'm almost finishing my gerber and I dont understand two things: the schematics says "eprom enable" it refers to OE(output enable) or CE(chip enable)? the second thing is: The 74133 output (pin 9) is connected to 7404 and than go to 7474 but the schematics doesn't say which pin, there is only this sign ">" what this mean? thank you.
  4. thank you for the answer, so only A1 and A2 are inverted before being connected on 74133 right? and A12 is inverted only to be connected on Eprom Enable?
  5. Can anybody answer my questions? why A1 and A2 are described as /A1 and /A2?(what do the slashes mean?)
  6. Hey, jsoper I tried to use your schematics do make the circuit but there are two things I(noob) don't understand. first: why address A1 and A2 are described as /A1 and /A2?(what do the slashes mean?) and where is 7404 connected in the circuit? thank you!
  7. I need your drawings but not in gerber format, I want to print the 2 sides of the circuit separately to make my own pcb of this board.
  8. If someone tested the board or ciruit plese share the results.
  9. I'm looking now for Montezuma's revenge or any Parker Brother's pcb schematics or diagram, but can't find anything. Know where I can find this kind of information?
  10. I start the tests with the 4 in 1 "27C256_Phoenix_Hero_Kangaroo_Ms pac man" and only Hero don't worked, so I separeted the 4 games and replaced "Hero" with other "Hero" from the 4x1 dump of the thread above, so the 4 games work.
  11. The pcb schematics and pictures of the first thread, with the games of the second one is exactly what I have, I think the dumps you send me will not work on this pcb/bankswitch, but I will test anyway.
  12. Hello my friend, I need games with the same bankswitch of this cartridge, have you done a dump? know where I can find 8k games with the same bankswitch?
  13. Hello friends, I need the dump of these four 8k games or other dumps (8k games) with the same bankswitch to use on a pcb identical to this post.
