[Coco] Multi-Processor 6809 Computer System

[Kip Koon]

Mark,
I'm eager to see what you have come up with.  It all sounds very
interesting!  :)  I would like to encourage you to finish you mammoth
project, and when you can to share with us your progress along to way if you
can.  :)  
Have Fun!
Kip

As I've mentioned before, it is going to be difficult to design a Coco
replacement and even get anywhere near breaking even in the long run. It
will have to be a labour of love for someone...

FWIW I'm currently designing a custom FPGA board for my own purposes -
primarily for the prototyping of a specific emulation not related to Coco -
but also to be used for "play" over the next 5 years or so - it is
ridiculously over-engineered! With that in mind, the design does include
expansion capabilities, and I've specifically been thinking about the Coco
along the way. The base board, along with a relatively simple 2-layer
expansion PCB, should have everything that you could possibly want on a
Coco-X, and much more.

The board itself will cost way, way more than any Coco enthusiast could
possibly justify spending (it's not for sale anyway) but I was intending to
port both my own Coco1/2 and Gary's Coco3FPGA designs to it, and 'showcase' 
the possibilities in a video. I think in these types of cases, a picture (or
video) is worth a thousand words, and it might just be enough to get people
enthused again. And of course the future possibility exists to down-scale
the design specifically for a Coco-X application.

Mind you, it's a big project and completion is many, many months away at
this point, as I'm still in the schematic capture phase. Layout is going to
be a mammoth task, and it may very well stall there forever. So take all
this with a grain of salt.

Regards,
