I finally finished mu dedicated programmer / bootlad board

just pop in on of these nerdkit compatible chips

ATMEGA324PA-PU

ATMEGA324PA-AU

ATTINY85-20PU

ATMEGA328P-AU

And its hardwired into the ISP chip. Here is the wire diagram. One big happy family

Wow Scooter you sure put a lot of thought and insight into this project. I have thought about some of this so I could burn a chip and plug it into one of my many projects. I will study this more and will have a ton of questions I suspect.

Good job

When I first got my Nerdkit and my curiosity was really peaked, I purchased a ATMEL STK600 development kit for 8 bit and 32 bit microprocessors. It came with adapters for most of Atmel's micro processors plus I bought some newer adapters.

I probable have $800.00 or more tied up in the the damm thing.

Damm because I never used it for a couple of years and when I did a KNOWN weak voltage regulator blew.

I have a replacement regulator, but have never gotten around to installing it.

It's on my one of these days list or maybe ebay.
