Hello all,

I am having some problems with building a replacement for an AVRISP. 
The schematic is in the files section (AVRISP.DXF). I get errors when 
I try to program the AtTiny2313 with AVR Studio 4. 

Setting mode and device parameters.. OK!
Entering programming mode.. FAILED!
Leaving programming mode.. OK!

The 2313 does have external power and the jumper on the reset line is 
on. I did check to make sure the reset line is being pulled low. Is 
there anything obvious that I am missing? Here is the reference 
design I was trying to copy.

The only reason I am trying to copy this is because we are still 
using the AtMega103 and need a programmer. The MKII does not support 
the 103.

thanks,
Draper
