[Amforth-devel] amforth-1.3 on atmega8

[<ha...@hu...>]

Hi,

I found amforth yesterday and was very happy about that!  I'm teaching
my son Forth as the first programming language and it would be very
cool if he could have some fun with an AVR.

I am now trying to run amforth-1.3 on an atmega8l-8pi.  Compiling and
flashing the software went fine, and I get the startup banner.
Interactive commands work, but if I try to define a word, the system
crashes and I seem to need to reprogram the eeprom to recover.  Does
anyone have a hint?
