Re: [Amforth-devel] Marker etc.

Al,

Yeah, atmega8 is more a mee-too system. Not really usable any more. If
you really want to use such little systems, you will have to go back
in time and use versions around 1.x or so.

Ok, but it is already mentioned ;=)

It already worked, and does not currently. But it will do so again.
But dont ask, when...

Your complaints are welcome, but what could I do? Others complain that
the scripts do not work at all due to <whatever>. I use the scripts on 
my systems and they work good enough. Maybe I intuitivly circumvent all 
the bugs and deficits already ;=)

> So as it stands now I must use a crystal or resonator

Most people who work with atmegas strongly recommend to use a quartz 
when it comes to serial communication (even at low speed such as 9600
characters per second). The internal oscillator works at 8MHz which is
cut down to 1MHz and it is known to be very unstable.

And again: marker is currently broken, sorry for that. But it will
come back. Sooner or later.
