Talk:Mario Bros. (TMA1)
Initial notes about this page
I've gone down a bit of a rabbithole with this board and went on a spree of aggressively documenting every capacitor I could read on this board, readable or not.
- The series markings on all of the Rubycon axial capacitors are face-down so I can't get a look at them without desoldering, but I'd imagine they're also CE W or similar.
- I'm not the most experienced in selecting replacement capacitors so I haven't populated that list yet at all, but if I'm not mistaken (and based on what I could actually see in stock on Digikey), Rubycon TWL & YXJ capacitors and Cornell Dubilier TTA capacitors might be good options for replacing the radial and axial electrolytics respectively?
- There's also a few glaring Weird details about this board in particular, like that strange bridging of components across chip 4H near the center of the board. Maybe not the best example for a visual reference, but it was good enough for me to get a close-up image of every single capacitor on the board and its markings which helped along documentation a ton, though I dunno if there's exactly much need or place to provide those close-up images for every single capacitor present as a reference.
I feel as if maybe I should include a couple references aside from the archive.org schematic view and one or other uploads of the full manual that I'm worried may link-rot if I choose to link those, but aside from the paper material most of the information is what I've observed and tested directly with this board. 666666t (talk) 12:57, 7 January 2025 (UTC)
As far as the capacitor replacement series you mentioned, those look good. This isn't an analog board so they aren't doing very complicated things. The YXJ are a staple for replacements. Axial are a little tougher but I don't see anything wrong with the series you picked.
