VCALC.net

VCALC.net is the best place to go for info on the Curta and the more you look the more you find....  The simulators have been key to understanding what each bit does.  I am slowly going through the 'Curta Disassembly' slides and it is both a super good explanation of each part and a crazy look at how small these parts are.  Holy crap!!!  I am going to have a hard enough time making these parts at 3x scale!
