The ElectriClerk

The ElectriClerk is a fully functional 1988 Mac with a 1923 Underwood typewriter made by Andrew Leman...

"Built for a game of Cthulhu Lives! that has yet to be played, this piece was inspired by the retro-futuristic machines in the movie Brazil by Terry Gilliam. It was one of the most difficult and time-consuming pieces I've ever attempted. Despite the ridiculous amount of abuse I subjected it to, and despite the fact that all its components are now exposed to the air, the 1988 Macintosh SE which forms the heart of this piece still works just fine."
