Ted,

Can't help with Bascom but if you want to add a bit more to the challenge there 
is always C.  There is a good book doing the rounds of the tech colleges and 
uni's. "Embedded C Programming and the Atmel AVR" by Barnett, Cox, O'Cull. After 
assy C can't be that bad.

There is a good level of support from the WinAVR build of GCC for free and tons 
of people using it both privately and commercially.

I dislike C immensely but it pays the bills, having said this I disliked 
embedded basics even more so seeing as though there are few forth programmers 
left to be able to employ, C won as the best of the worst ;-)
( Potential candidate for "grumpy old men" )

Vague recollections of seeing my first calculator that didn't need a desk to 
hold it up and programming a 2650 via front panel toggle switches so we may not 
be that far apart.
