You'll find links to other strange calculators on strangecalc.ch. Have a look at the R500/7T relay computer built by a colleague; the machine is located in the office where I work.
Enjoy, Juergen

My wife wants me to make such a machine out of Meccano (my other addiction/hobby). I've resisted so far...
