AVR-Chat

Cat;

  Yes, the AVR-Lite is supported, I foudn out that AVRDude supported it 
by Googling AV%R-Lite.  It isn;t clear to me how IN inform AVRDude that 
I am using an AVR-Lite, however, I saw nothing in the AVRDude GUI that 
permitted selection of programmer type.

  As for reverse engineering, it is a pure Parallel dongle.  3 sockets 
(8, 20 & 40 pin) 6 resistors, 2 LEDs and one cap.   That and the DB-25F 
connector on the end of the PCB.  Very simple.  Obviously, if can only 
program ASVRs which have the MISO and MSOI * SCLK pins inthe places 
which are hardwired on the PCB, so newer  AVRs than the AVR-Lite may not 
work with it, but that isn't the difficulty here, the ATtiny2313 has the 
same pinout as the AT90S2313, which existed at the time of manufacture 
(or at least, at the time I purchased the thing off of eBay)  And both 
chips are listed in the processor selection pulldown menu, so I am 
reasonably (*grin*) certain it is supported, you know?  *heh*
