While researching some information on the old CP/M operating system (don’t ask) I found Herb Johnson’s excellent retrotechnology.{com,net} website. It’s chock full of good information on old Apple Macintosh systems, S-100 systems, and cool virtual exhibit on the PDP-11. Bookmarked for later consumption: tons of good information.

Addendum: It’s amazing how often I find people with odd interests have other odd interests that coincide with mine. Herb has also ground and polished his own telescope mirror. Awesome.
