I'm working on an update for some old code for a PIC16F506. I have an
AC162070 header connected to a PIC Kit 3 through a Microchip SIP to RJ
connector board and an RJ cable. To ensure my target is not messing it up,
I've told the PIC Kit 3 to supply power to the host and do not have the
header board plugged into the header. I can see 5V on pin 18 of the ICD
device. It SEEMS like I should be able to just program the device like
this. But, I'm getting the following error when I try to program it:

Programming...
The following memory regions failed to program correctly:
Program Memory
Address: 00000000 Expected Value: 000004a3 Received Value: 00000000
Programming failed

At debugger start, I also get this:

PICkit 3 Connected.
The target has invalid calibration data (0).

Ideas?

THANKS!

Harold
