Same with me. I borrowed a very nice HP-25 keyboard for my Panamatik Low Power calculator. But I didn't touch it's perfectly working circuit board and used a non-working one specifically acquired from eBay for that purpose instead.
And I already wrote on this thread (or on a similar one) that I could not sacrifice a perfectly working Woodstock-series calculator to turn in into a low-power version. There still must be plenty of dead units out there which are much better suited for that task! It is just a matter of patience...

NB: I soldered that 100µF capacitor into my board. No difference, unfortunately. Whenever the GPS is turned on and my LP25 goes into sleep mode (either by pressing "f divide" or using the power switch) it will wake up calling itself an "HP-00" and only disconnecting and reconnecting the batteries will bring it back to useful life. The simple workaround is to make sure that the GPS is turned off before the calculator gets turned off... I tried with fully charged NiMH batteries and with new Alkalines. No difference.
