Support for Rototron Rotary Joystick Interface?

[mark shaker]

Oops...

I blew something (probably the IC) in my Rototron Rotary Joystick Interface when I accidentally fed it 12V rather than 5V.

Is there anyway to get a replacement IC?

You probably fried the Atmel microcontroller chip (5.5V is their limit).
You could get another chip and program it yourself.  I have the code on my site.  You would need an Atmel ATtiny2313-20PI chip which I think is discontinued.  However, the ATtiny2313-20PU replacement will also work.  You can get a few free samples from the Atmel site. 
Otherwise send me a message and I will arrange a repair for you.

Thank you for the information!

Can the ATtiny2313-20PU be programmed with an EPROM Burner?
If so, I can take care of it myself.

I doubt you could program it with an EPROM burner.  However, you can build a simple AVR programmer for under $2 in just a few minutes.  I have plans on my site.  Also, the free Bascom AVR programming software can be downloaded from MCS Electronics.
