I love old and weird computers. Especially computers that are old and weird—the kinds of devices that represent the end of an evolutionary path, or ones that were significantly ahead of their time.

Keeping a number of these devices working and useful can be a bit of a challenge, so I thought I’d collect together my own notes on the process. First and foremost, these are working documents intended to serve as a reference for me, but hopefully they prove useful for others who are trying to do similar things, or are just curious.
