Hi, Kenpo
Just link a pot to the servo arm, and record the voltage at cursor with an ADC in PIC.
Recording ( and playback after !!! ) will be done into a huge EEPROM outside the PIC ...
I'f you're a fine hobbyist .... use the feedback pot wiper inside the servo, it's supply voltage is already regulated !!!

PS : just think the servo gears won't appreciate your teaching too long a time ... a joystick to drive the servo would be smarter ...
