I'm trying to trace out the jumper Pak's connections to attempt an on-board expansion pak transplant and removing the expansion slot entirely (mounting the resistors and caps on the board as well), but something just doesn't make sense to me when I'm looking at the jumper pak. There are 5 capacitors on the board, but 4 of them appear to be connected to ground on both sides. I took some pictures to show what I mean, and I marked the vias and traced the components onto the front-side image so I could see which components connected to which pins. All of the green vias are ground, so are the yellow (but I didn't realize that when I initially marked them), the red connect to the resistors, and the one blue via is the only connection to a cap that makes sense to me. Unless I'm missing something, the other 4 caps are just shorted across 2 regions of ground which are already connected by a trace, so they're not bridging the regions (you can follow the trace straight up from the yellow vias on the back of the board straight to several other ground vias). Can anybody tell me what's going on there? Also, does anybody know what value the caps are? They have no marking whatsoever. The resistor arrays are marked as 51ohm, so at least I know them.
