Worked for a couple of hours tonight cutting/tinning wire and then soldering it to the 600 contacts on the cartridge slot. I finished the board half and then got pretty frustrated with the slot half. I decided to desolder the few that I got connected to the slot pins and just tin all 68 contacts to set up another try tomorrow. The last thing I want to do is solder all of them and find out later that the connections aren’t strong enough.
I just want to get over this hump so I can finally test it! Gotta be patient though, I know that’s the name of this game.
