Retro computer kits

This is my theme and blurb I came up with: "David Greelish, Founder of the Atlanta Historical Computing Society, will give a presentation on the history of computers, and especially show how the modern Make movement parallels the early "homebrew" computing hobbyists. Plus, a look at electronic retrocomputing kits and accessories." Could everyone help me brainstorm on exactly what all is out there that you can actually buy to build now? retrocomputing kits: Briel - replica 1, Altair 8800micro, micro-KIM, PocketTerm, a2mp3 and others FIGnition Digi-Comp I Gakken 4 Bit Micro Computer Accessory kits: CFFA3000 CompactFlash reader / IDE for Apple II IDE64 CompactFlash reader / IDE for Commodore 64 ZoomFloppy for Commodore disk drives PETdisk microSD reader for the Commodore PET Help.
