I am using PBP3 and a Minipro TL866 to program 16F6218a PICs on a breadboard.
On the programmer, I set the configuration word to use the internal clock
The Pics seem to program fine and read back fine, including the config register.
Already wasted two days on this and getting disillusioned. In the past I programmed PICs with older Picbasic versions no problem.
