Newbie Power Supply Question

I'm new to PIC programming and recently bought a PIC programmer off EBay. It came with a PIC programmer that connects via a USB cable. Attachable to that programmer is the ZIF socket that holds the actual microcontroller. Since I am utilizing the USB port to power the programmer the software tells me that I need to find a seperate power supply for the target chip in the ZIF socket. I am just having trouble figuring out how to power the IC in the ZIF socket. Do I just lead in the appropriate power and ground wires to the pins of the IC or do I utilize this array of pins on the corner of the board(picture attached).

Going by the programmer I buit, VPP is normally 13V and VDD is nomally 5V.

You can buy mains adaptors with a 5V output but the 13V is a bit more difficult.

12V might work though, a 12V regulated adaptor could supply you with the 5V if you add a LM78L05 regulator on the output.

If 12V doesn't work then you really need 13V, then you could use the power supply from the PIC programmer on Nigel's site:

thats strange, programmer asking for external power source is understandable but its asking also for PGD & PGC !!! whats the usb for then ?

looks like the ports you showing is for ICSP.
 
I'm trying to program the PIC16F628A. Here is the ebay auction of the PIC programmer I bought: **broken link removed**
So if I were to power the target separately, since I am powering the programmer with the USB port, would I just run power and ground wires into the ZIF socket?
 
No you don't power the programmer with USB. USB gives only 5 V but you need Vpp which is 13 V.
 
Ya, it should have maybe an adapter to the programmer board, then there should be a socket connected from the board to the zif.
