I have several damaged AVRISPs. I would like to replace the 90S1200 and 90S8535 with 90S2313 and Mega8535 since we have these in stock. I've tried reading the firmware out of a good programmer but it is code protected. I've also tried programming the 2313 with the AVRProg firmware in AVR910.asm but the software indicates that no support board is found. Once I have the firmware for the 2313 I can program a new 8535. Or, is the firmware file STK500.ebn available in a non-encrypted format? Any ideas?
