ebay - 41C for 100 USD

You can convert it to a CL and you will have the ultimative 41 calculator!

Then use one of these.

not sure I want to spend $55 on the battery shield if the calc is no good.
Same is true for turning it into a super duper 41.

I think what I'll try is to clean up the crud then maybe redo some traces (if I can). Attached the correct voltage to the circuit board and if calc is OK, then it may make sense to keep going with replacement parts.

One thing I'm not clear about is if I want to conver to a CL, how much of the original circuit boards need to be intact/working?
