Hi,

first of all, thanks for converting these schematics to Kicad!

I have modified them slightly:

  • Some of the labels & symbols have been renamed to those used by Commodore in the official schematics (cf https://www.amigawiki.org/doku.php?id=en:service:schematics). Nocash used his own labels but it is probably better to use Commodore's.
  • The handmade connector was replaced by a standard one from the Kicad library.
  • The LED section was made into its own functional block to avoid unnecessary wires.

Also, since I use Kicad 5, it has also automatically converted the files by modifying internal library references. I am not too knowledgeable in this area but everything seems to work fine after that.
I have included the conversion report so you can give it a look if needed.

And this is about all.
If you want to incorporate these changes to your repo, you are more than welcome, I personally would not want to maintain my own fork of your work. ;)

Update:
After a notice on the EAB by solarmon about an error, I made some additional changes (they are part of this request):

  • fixed the label of pin 15 of the 6570 (it was the same as that of pin14)
  • renamed the 6570 part pins to not include external function anymore, this was moved to dedicated labels at the wire/pin junctions
  • respaced some pins slightly
  • renamed some symbols again to match terms used in Commodore or other sources (cf commit messages for details)

Note that I have not regenerated a PDF corresponding to these changes since I have no idea how to do it.

Feel free to ask any questions if anything comes to mind.

Thanks again for your work!

Cheers,
Laurent

- No changes aside from the conversion were made to the files.
- Added project conversion report.
- Added .gitignore to avoid versioning unnecessary files and folders:
  - "rescue-backup" folder generated during the Kicad5 conversion,
  - backup files generated during save.
- Renamed symbols to conform to those of the official Commodore A500/A500+ schematics.
- Fixed Labels to properly match their Input/Output status (they were showing as bidirectional).
- Now uses a connector from the standard KiCad library.
- Made the LEDs section into its own functional block away from the connector.
- MOS 6570:
  - Renamed pins to not include their in-circuit function but just their name as specified by MOS. Labels were moved to wire/pin junctions.
  - Fixed the spacing of a few pins so that all adjacent pins have the same spacing.
- Circuit
  - Added wire/pin junctions labels around the 6570 to indicate usage (were previously part of the pin labels).
  - Fixed a duplicate label pointed out by solarmon on the English Amiga Board (http://eab.abime.net/showpost.php?p=1391450&postcount=16).
  - Renamed these labels to names used by Commodore (when available) or on https://www.amiga-stuff.com/hardware/6500_1.html when they did not conflict with the Commodore ones.
