Put together a program board for a 12f1822 and when try to DL a prog get the following:

Running self test...
Self test completed
Firmware Suite Version...... 01.28.90
Firmware type......................Enhanced Midrange
PICkit 3 Connected.
Target Detected
Target Device ID (00000000) does not match expected Device
ID (00002700).

Programming...
The following memory regions failed to program correctly:
Program Memory
Address: 00000000 Expected Value: 00000021 Received Value: 00000000
Programming failed


Any clues as to the cause, or what to correct it?
All connections appear correct. It seems target detected but ID?
Max.

Target ID 00000.... generally means PK3 can't communicate with the PIC.
ICSPDAT and ICSPCLK right way round?
Other components on MCLR, ICSPDAT, ICSPCLK interfering?
