After saving my original TL866A (thank you radioman) and a 100 ohm resistor (thank you Georg Simon), now using the programmer again, I was remembered of some lacks and misshaped concepts of the enclosed software.
(points may only be valid for various Atmel AVR-chips)
1. 'device/erase' or 'erase before' erases flash and sets fuses to their default value
this is confusing non standard behavior
erasing should only erase the flash
2. in the 'chip program' dialog you have to check 'Con.FUSE Bit'* for programming the flash
otherwise fuses are set to their default value
this is a consequence of point 1.
3. programming out of the buffer
every software change forces to reload the buffer manually
costs a lot of (boring) clicks when developing and testing
a function to program right from a hex or bin file would be appreciated
4. the 'chip program' dialog opens with all options checked when a project is loaded
seems like an error, should be fixed
(with no project loaded this dialog remembers options)
* 'Con.FUSE Bit' this label seems to say it
