If you are using the 16C overlay, it should not matter if the keys under the overlay are the 12C keys…. Is there any difference in speed between the 12C and 12C platinum if the 15C firmware is uploaded? Can this even be done?

I have ordered the cable from TheCalculatorStore.com and am excited about the possibilities!

I also have the HP-15C LE and wish I could upgrade the firmware, but don’t have the correct cable nor the required software and files…

I believe the 12C Platinum is 6502 CPU based. I think you would need a recent 12C, to get the correct hardware.
