Hello all. To help me learn more about the SNES, how all the components are connected together, and how they interact with one another, I thought I would go ahead and create a schematic of the system's PCB. The couple that are
currently available are pretty horrible. It's also helping me learn how to use the schematic capture software that I have. Would anyone find this useful or think it would be good to post? Or not really? Maybe there are some much better schematics that already exist that I just don't know about? If someone thinks it has value then where would be a good place to post it?
I've only just started, but
here is a screenshot. The screenshot isn't legible just because it's zoomed out so far, but the actual schematic when printed to PDF (or whatever) is ultra-high resolution.
I am having to manually create all the nintendo custom components and having to define each individual pin so it's taking a while and is pretty tedious. But I have definitely learned a lot even with the little that I've done so far - so it's worth it.
Also, _major_ credit to the nocash's
fullsnes doc. It has been invaluable for getting all of the component pinouts, signal names, and pin numbers.
