Now this is what I call a casemod
...and a half.
The ElectriClerk was built as a prop for "a game of 'Cthulhu Lives' that has yet to be played". The builder took the guts of a 1988-vintage Mac and mounted them inside a 1923 Underwood typewriter. I particularly admire the trackba and number pad.
The maker's page also has the promotional literature he designed to go along with the "product".
Amazing stuff...
