12F509 / 609 ICSP problems

No, I don't have an adapter to program the IC outside of the circuit, that was the whole reason I chose ICSP.

What adapter(s) do you have? Are these SOIC? Narrow? Wide?

These fit into DIP adapters for programming and can be used in breadboards for testing.

No adapter needed. I am using it in circuit, except that I isolate power from the programming header pins on my target board. The programmer does not power the rest of the circuitry, only the chip. It works well, only if you use the pin#4 header on the USB programmer for switched Vdd. Any time I apply external power, it violates the cadence requirement called out in the data sheet. The order of logic levels on pins to put it in program mode is very finicky

I understand that you are using ICSP but others might find the adapters useful.
