I think when I made my mod chip I hacked together an adapter that plugged into the parallel port on my PC at the time. Now you can buy a ready to use USB PIC programmer for under $7 shipped from China though, there's no point in trying to build one. That is, assuming they will program the part you're using. That's a frustration I've had with PICs in general, seems like I'm always running into a situation where the part I want to use is not supported by any of the programmers I have.

I think I just need to buy a PICKIT 3 or the likes for now or even order the PIC12F508's already programmed with the Hex through Microchip. Doesn't even look like my board has a COM header for a Serial port to connect to in the rear of my PC.

Why buy a serial port and build a programmer when you can just buy a USB programmer for about the same price that will likely support more devices? The problem with a lot of the old legacy programmers is that the software expects direct access to the hardware, which is for the most part a thing of the past with modern operating systems.

They exist, but they are fundamentally flawed. They will work for some applications but not for this, AFAIK. My vague understanding is that USB protocol introduces interruptions and latency into the equation, so a USB-to-parallel can't do this in real-time.

I recommend you buy a PICIT2 or PICKIT3. And if you want a clone, that's fine, just don't buy a Sure Electronics.
PICKIT2 lost product support, so no modern devices have been added since I don't remember. Maybe something like 2013-14. So PICKIT3 is "better" if you want to do embedded programming with PICs. But to flash stuff, you have to install and load a bloated Java software and make half a million mouse clicks in a maze of mistakes-waiting-to-happen everytime you use it.
