The Retro Challenge is a one-month long excuse to do cool stuff with old computers and blog about it (vaguely wrapped up as a competition).

Last year I created the RetroMatic 2000 as my entry.

This year I have more modest aims. I have acquired a number of additional vintage computers over the last year, and have been nursing them back into life. The one that has eluded me so far though, is the Osborne 1.
