From seaching the internet, I found a few places where a JDM programmer is made to program an AVR mCU, but I couldn't find a project that does it the other way around.
I have two unprogrammed Microchip PICs: a PIC16F877A and a PIC16F84A.
My JDM programmer stopped working when my AVR interests began, halting my Microchip PIC projects.
The AVRs I have, are ATmega168, ATmega8L, ATmega8515, and ATtiny2313V. If any one of these microcontrollers can be made into a 'quick' JDM programmer, then please let me know. ('quick' meaning solderless breadboard, only.) Thanks in advance.
