It's all here. I'm using similar code on my OpenBase Donation kitchen. Though very insecure and slightly buggy (thank you ComputerCraft 1.6 for breaking the Redstone API) it is my best attempt to make a keycard-based lock.
Have you been able to edit the code through GitHub and get it onto the computers? If you can I'll gladly use that...
Yes, in fact, I uploaded them directly from the IDE. By unfinished I mostly mean CC 1.6 breaking stuff.
