Re: [Amforth-devel] Connection to host

Yup ISP is it, there are a few options.

1. As below.
2. Google Pony Programmer, and make up a parallel port to ISP adapter 
from the schematic (Drive with avrdude)
3. If you have an arduino and the ver 18 IDE there is an AVRISP sketch 
as part of the examples that can be used to convert the Arduino into an 
AVRISP programmer.
4. Buy  puker Atmel AVRISP

One or other of the above are worth having. Even if you down tools on 
Forth and later go for arduino having the above to burn bootloaders into 
blank chips is great for your own projects. (Prototyped on an arduino)

Hope some of this helps.

Cheers
