And guess what, I now have a fully functional 70 working! It even does Canadian Mortgages, of course that will all change with the new Prime Minister.

Congratulations on getting the 70 to work! 45s are, although very nice calculators, quite cheap. So it makes perfekt sense to sacrifice one to resurect a 70!
