#186140 - I'd be wary
Responding to: Jim Granville's previous message
I don't think the boards that work with ISP studio are at distributors yet, but the code and sch's are on Atmel's website. One uses a LP4052, so once you find/borrow a parallel port PC + cable, you are good to go.

The one linked above

looks very cheap at $3.90 and it has a HCT244, so my guess is it is a clone of the At89ISP.


there has, over the years, been a multitude of posts "why does my homemade AT 'cable' not work" and all have ended "give up and go buy the blasted thing fromm Atmel"
