520STe bottom board photos c300779-001 REV 5.1

Post by nokturnal »

Anyone has good photos of 520STe's bottom pcb (c300779-001 REV 5.1) around ym, dma, u306, u307 section or maybe more up to date ste schematics than those in normal circulation?

Thanks,
nokturnal

as for "up to date" schematics, other than the usual scans that can be found, I did a conversion into Kicad last summer : https://github.com/sporniket/kicad-conv ... /tag/1.0.0

I used @sporniket's schematic when repairing Brett's STE, it's an invaluable resource and my job would have been a lot harder without it.

@sporniket I am wondering how much work would be involved in making something like this for Atari: https://www.amigapcb.org/

Perhaps some of the Amiga guys on this forum might know who runs it and whether the backend is open source, or even if they'd allow someone to use it for an Atari PCB site.

@steve the key element is indeed the toolset to generate the pcb explorer, and how much effort is required to get a similar explorer.

And then, there is the effort (time and cost) of setting up and maintaining of a dedicated website to take into account.
