building my own relay computer

[Rick Bensene]

I have often thought it would be cool to build a relay calculator, along the lines of Casio's relay calculators that they marketed for a time in the 1950's before it became clear that electronics were the way to go. They even made some scientific and programmable machines, but a basic four-function machine with an accumulating memory register would be enough.
