I acquire these calculators mostly in non-working condition and meticulously repair and restore them using my 50 years of electronics experience. Unlike most sellers, I fully document every fault found and every repair performed, so you know exactly what you are getting and can buy with confidence.
I buy calculators at good prices, restore them, and resell them with a modest margin that covers costs and fees. The profit is not large relative to the time involved in repairs.
My focus is the craft of restoration and preservation of these calculators for enjoyment and as working tools.
