  • Donkey Kong TKG4-14 PCB Reproduction

    I've started to do a 1:1 reproduction of the TKG4 2 layer board set. The PCB Gerber files will be made open source for anyone that wants to get the boards fabricated through their preferred board house (I use JLCPCB) and assemble it themselves (or pay someone else to if you don't have the skills). The cost of the PCB and components would amount to around the same cost as an original PCB delivered to Australia (if you can find one) so there's no commercial viability in it and I'm pretty sure there may be copyright issues if sold commercially. I have a CPU board set that has track rot on the top layer (TKG4-14-CPU) which is my primary reason for doing it and I most likely just do the CPU board first and test/debug before moving onto the video PCB.
    The PCB has been stripped and scanned, all component locations have been measured from the original PCB to ensure accuracy to within about 0.5mm.

    PCB scans..





    I've started to layout the components on the PCB, the footprints/silkscreen layer needs to be created/edited to match the components on the original PCB (this is taking a considerable amount of time) then each component has it's X-Y coordinates measured before placing it on the board. 270 components have been placed so far with about another 150 caps to go as well as the pots and connectors then I can start laying out the tracks.

    10 out of 10 mate amazing work and time consuming I'm sure.

      Thanks mate, I have 20 hours on it so far and expect it to take around 100, same for the video PCB.

        This is bloody cool. How would these stand when being used in official comps? As you are making them exactly the same, you could assume the game would play 100% accurate right? However, I expect places like Twin Galaxies would demand an original board for record purposes. Despite the fact your repros would likely be the same in all respects.

          They would be exactly the same as an original but I wouldn't use them for comps. Good for backup boards and repro cabinets etc.

            WOW! That's going to be a lot of work hand soldering or are you going to solder wave the joints?

              Very very cool!!!

              Are you firm on it being 100% original, would be great to convert the 2532 ROM sockets to be 2732 wired on the board, or add jumpers to set which pinout. 25 series being hard to find and hard to program these days.

                Great work Adam

                I'd be interested in one to populate

                  The PCB file can be edited so it's not much work to do a revision that will use 2732's or have jumpers like you suggested.

                      Yeah this is cool!

                      I think you'd sell a few more than you think.

                        Just out of curiosity if your getting blank boards made would you be interested in getting extra made and selling the blanks. Either way excellent on recreating these boards.

                          That shouldn't be an issue, I'll get the first one completed and tested before doing a larger run of boards.

                            Actually, I think the ECL components will be more of an issue than the 2532's

                              You can still get the ECL chips though there are limited quantities left.
                              I'm also looking at doing my own version of the Jamma adapter.
                              Edit: DK Jamma adapter done, see here.
