Opry99er Posted April 19, 2018 Share Posted April 19, 2018 Just what the title says. Trial and error. The first attempt did not end well, as I put the switch ports too close together (trying to match the switch ports to their relative solder locations on the board) and the case didnt like it. I got it to *kind of* close, but bad things happened when the longer switch leg on switch #2 came into contact with the EA GROM pin. In addition to that, the LED leg was touching one of the pins of the RAM chip. Needless to say, when plugged in, the console wouldnt even boot.... I dont want to even think what the console thought was plugged into it.... glad I didnt damage anything. 2 Quote Link to comment Share on other sites More sharing options...
Opry99er Posted April 19, 2018 Author Share Posted April 19, 2018 So I sacrificed another copy of HouseHold Budget Management, and this time set it up so the two switch ports would correspond to the gap between the two chips and the gap between the EA GROM and the battery. I also shortened the LED legs and moved all my case ports up higher on the face. This one had a much better outcome. 3 Quote Link to comment Share on other sites More sharing options...
Opry99er Posted April 19, 2018 Author Share Posted April 19, 2018 You can see that the difference between spacing is slight, but it made all the difference. The top pic is the first attempt (forced closed) and the second is the final version that works beautifully. Quote Link to comment Share on other sites More sharing options...
Opry99er Posted April 19, 2018 Author Share Posted April 19, 2018 One interesting point of note: the two HBM boards look very different from one another. 1 Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted April 20, 2018 Share Posted April 20, 2018 They're just different board lots. I've seen five or six different lots for that five-GROM board. It doesn't matter which two slots the GROMs are in, and both boards have the standard two capacitors and a resistor. Good job with the cartridge! I need to order some more of those boards. . . 1 Quote Link to comment Share on other sites More sharing options...
Opry99er Posted April 20, 2018 Author Share Posted April 20, 2018 (edited) Thanks Jim!!! I would buy at least 1 more if it were available... probably more than 1. I want my son to help me assemble one as our first collaborative hardware soldering project. Likely have him do the simpler solder joints and Ill do the tighter ones. I will probably have him practice on the HBM boards I just disassembled.... have him solder wires through the holes, etc.... desolder the GROMs, replace them in a different spots. Will be fun. Anyway, after I did my cart case, I saw acadiels from a while back.... soooooooo pretty. Edited April 20, 2018 by Opry99er 2 Quote Link to comment Share on other sites More sharing options...
