I've got an old ATtiny22 in a drawer, which announces itself as an AT90S2343 (both devices were mostly the same anyway). I tried a few combinations of programmers: . Genuine STK500 running v2 firmware: does not work at all, ISP startup fails. Perhaps the same issue as you are seeing with the dragon. . AVRISP mkII: works flawlessly. . AVRISP mkI (also running v2.x firmware): works flawlessly. . AVR Dragon: works flawlessly. . JTAG ICE mkII (in ISP mode): basically works, but apparently has issues talking to the device. The empty EEPROM pattern is read out with interspersed junk data. . Matthias Weißer's USBisp, running his own STK500v2 protocol implementation: works flawlessly. -- cheers, J"org .-.-. --... ...-- -.. .
