In this video I teardown and cleanup a 20 year old Swintec 401DP printing desk calculator.  It was still working and I needed a good desk calculator for my bench.

I cover how some of the electronics work as well as the mechanics and of course my efforts cleaning and greasing it up into perfect working order. Good for another 20 years I say.

I picked this one up at Goodwill for $3.00 with 10 rolls of paper. It might have worked but it was in horrible condition and filthy as you can imagine, it had a hard life. Still Goodwill is a great place to score old electronics.  Normally I don’t fix stuff I get from Goodwill I just tear it down for fun and for spare parts. The old parts are still the best for hacking.
