[avr-gcc-list] ATTiny2313 for AVRDUDE?

[Bob Paddock]

I asked Atmel what the device codes for the ATTiny2313 should be, this was
their response:

Atmel> Sorry about the delay in responding and even more sorry about
Atmel> the answer. The official answer from the factory is that there
Atmel> is no device code for the Tiny2313. They suggest using a
Atmel> different programmer, like the AVR-ISP.

When we use the AVR-ISP it only lasted about a month, then failed and shut
down production.  Happened several times before we gave up on the AVR-ISP 
route.

Is it possible for Tiny2313 to not have a device code?  Seems unlikely.

I've got Tiny2313's in hand, O'scope, logic analyzer and other equipment 
warming up if some one can point me in the direction of what I should be 
looking for to figure out the needed codes.
