What actually peaked my interest in a 6809 SBC was that I came 
across software and a board design that controlled a telescope. It 
did in 64K almost all what the Meade Autostar 492 unit did with an 
HC11 and 512K of flash. Needles to say it perked my interest.

On downloading the software and nearly pulling what very  little of 
my remaining hair ontop of my head, I saw this breif little phrase in 
the binary file :

Fig Forth.  

After some breif searches on the internet and so education. I 
concluded that the contrtoller software was written in Forth. An 
interesting languange/os. It uses every register in the 6809 as 
pointers. Basically it is a stack oriented and extensible language/os.

definitions from the base. 

Awkward to write for but very compact and relatively fast execution.
