No, it wasn't a mainstream machine (there's only one exactly like it), and
I didn't think there would be much interest - who's going to build up a
chunk of hardware just to play with my design. A number of people have built
simpler (ie: Just the 6809, RAM, FDC and serial console) systems to run
CUBIX over the years, but none lately that I am aware of ... The simulator
allows you to get a pretty good feel for what the system is like without
having to invest any time in building it, and is probably as immortal as
it will ever get.

At the time I designed the system, I don't think I had even seen a CoCo disk
controller, in fact I may not even have had a CoCo yet. I am a huge 6809 fan,
but I never really got "into" the CoCo, so I don't think you will see any
substantial influence from the CoCo in the design. I used the 765 because I
had a spare one in my part box.

Btw, the system is documented in detail, complete with "inside and out" photos
on my site.

Dave
