Does anybody know the signature & code [name] of the Atmega8L-8PU microcontroller, or where it can be found please? This chip is of course of the small Atmega8 family. The requirement is for insertion into the bootloader avrdude.conf file.
1E 93 07, same as for the ATmega8. In avrdude call it "m8" or "ATmega8"

Dear John
Confused of Cheshire. I had thought that might be the answere but when I attempt to program or boot load the Atmega8L-8UP I am told by AVRDude that the chip's signature is not the expected XX XX XX; this happens to be the signature of an Atmega8 as recorded in the averdude.conf file. I thought that if I could change the signature in averdude.conf then it might condescend to work
So do I swear seriously at it and hope it listens or is there something else I can do?
Try turning on verbose upload output in Preferences. A side effect of that is that you will get to see the values fetched from the chip. It is possible that the signature bytes have been erased or altered.

John,
I have carried out that operation however the emmanated text file is extensive so I have attempted to attach it for convenience of the forum space.
As you advised some one earlier in this thread that the UNO board should be an adequate carrier I have in fact used one. It reports the UNO, atmega328P-PU identity as 0x1e950f. It does not specify an ID for the Atmega8L although it does state in the compiler verbose:
Board arduino:avr:atmega8l doesn't define a 'build.board' preference. Auto-set to: AVR_ATMEGA8L
Board arduino:avr:atmega8 doesn't define a 'build.board' preference. Auto-set to: AVR_ATMEGA8
So am I correct in concluding that the 8L is as compatible as the 8 is in the Arduino IDE.
