and the number 6809 ...
Looking at his home page you got alot more stuff about old machines 
including a few 8's 11's and 12's.
I think cubix was a good idea, but this 15 years too late for me as I 
realize in hindsight that 128k of
memory - split code and data is needed for any real work. This the 
crummy 8088 has but not the 6809.
Part of the reason I building a 9/18 bit cpu ( If I can ever keep the 
same instruction set or bit with --
next week it could be 12/24 bits using 2901 bit slices rather than the 
CPLD's I have ) is that I have
256k of memory something that I feel is right for a 'small'  computer.  
With the CPLD's I can run @
1.25 MHZ and get the feel for home-brew other than the PC or COCO-3 
options I had at the time.
I did have a COCO-3 but I never did get memory or OS9-II and a HD to 
upgrade it to a real machine.
