finished the Amiga cable and buttoned it up, now audio goes through breakout to the pvm instead of needing external speakers https://computerfairi.es/media/nsRAewroD1F12Lz0Kak

oh my god i finally get to watch this demo running on an real amiga https://computerfairi.es/media/6i6ySiQ4anAJXK4GcaQ

desk aftermath https://computerfairi.es/media/vWki-9UQJfWa6DzAhcE

and now that i have this rgb cable i can FINALLY play PAL games in the proper resolution and colour aaaa https://computerfairi.es/media/r_u6fxUTtmwtsS5gTAI

measuring continuity across every key pads showed around 100-300 ohm across each, except for the spacebar which showed over 1k. so i took some conductive paint and put some over the pad and dried it with a hair drier, now the spacebar measures around 100 ohms and works perfectly!

oh my circuits all rows are working

only the spacebar doesn't seem to be cooperating well because the conductive pad below it might be worn out

this is the first time I've gotten this keyboard working properly since i bought this back in 2007

*wipes brow*
i think the negative of the cap (-12v supply only goes to the other side of the board through the via after all

now to see if the keyboard works fine

cap replacement looks good but i think the via at the top is supposed to go to some other pin because now there's a short across the new cap? i think i just read the schematic wrong (having a picture of a non destroyed board without the caps would help IMMENSELY)

cap cleanup.. none of the original pads remain but shouldn't be hard to tap into the ones the old owner/technician uncovered, apparently with a jackhammer https://computerfairi.es/media/omA7Lz2K43RCJgYjquk

attempted repair.. looks like this might be the only trace broken, even if the rest isn't great

considering putting clear nail polish on the rest but worried it might make it worse

need to see if i have a replacement for that blue cap https://computerfairi.es/media/0mxuJOfY7A3DIIX0UAE https://computerfairi.es/media/PcoJEV9dLrCm9DWoazQ

current state of affairs on the Amiga keyboard traces, i got it like this from the person i bought i from https://computerfairi.es/media/TXD3-6cFUv2j2t6qxKM

DE15 is kind of a bitch to solder but there we go (sans audio yet because i forgot which pins i used for that in the bnc breakout) https://computerfairi.es/media/NJfLKm5o4uZ_t-wVQZE

well that's the Amiga side done, time to flip it around and do it all over again https://computerfairi.es/media/mZXcWRoIgcHnyIMAb9M

one thing i hate about DB connectors: you can never tell which way they are

the DE15 connector at least is asymmetrical https://computerfairi.es/media/767VI4uyZYd88C7eces
