S/N 1926A HP 41C on TAS

[edwingatox]

I bought HP41C 1926A00248 recently. "Sold as-is, for parts or repair only". US$199.00.

This calculator was not fully functional: there was a crack in the screen and some LCD leakage. I cleaned the calculator and changed the frontal part with the screen from a 1943 calculator. The CPU is the original with 3 transistors and the other parts are from the 1926 calculator and it has the bugs.

The 1943 calculator has now the screen with the LCD leakage and its cpu is with 2 transistors but it works. 1943 calculator does not have the bugs.

The 1926 calculator is now cosmetically fine and has a Quad Memory Module and a card reader.

The card reader has MALFUNCTION, a little more of work.

The calculator is in Guatemala, Central America. I will try to upload photos if it is possible.

Best Regards, Edwin


PD. I tried to change screen to the 1943 from a 20XX and does not work. The screen is different, maybe that's the reason.

I learned that serial numbers are correlated within the week. Be careful with low numbers announced at high prices but that are not 1926 or similar. Eg 1940A00007 is not a low number. It is a number 7 into week 40. That is one of the many thousands produced.

Maybe 1926A00248, 249 or 250 calculators were the first 250 ?????
