That would be more correctly: s/Alex, Steven/Alex/ :-).  He's the man.  I'm a 
software guy with enough digital hardware knowledge to be dangerous (now, 
analog audio systems are another story, but who uses them anymore?).

I'm guess it's Microware OS-9.  I've started working with that environment on 
my Tandy CoCo and it's a lot of fun.

Every once in a while a Stellation Mill will pop up on eBay, but they always 
go for ridiculous amounts.  The nice thing about Alex's upcoming FPGA project 
board is that you can implement the 6809 (or, better yet, 6309) in 
synthesizable logic and have enough room left over for two or three more CPUs.

There are FPGA designs for the 6809 out there already for the picking.  The 
real chips are getting difficult to find and the 6309 just about impossible. 
Not like the 6502 and Z80, I'm afraid.
