Also, José at TheCalculatorStore has done a number of conversions of 41's into 41CLs and, in some cases, the original machines were fully functional -- meaning that he has a number of working, original circuit boards for sale.

See this link (remember to choose C, CV or CX in the product type drop down).

He offers an install service as well.
