[Coco] CoCo4! 50% done!

[Al Hartman]

I would rather have a clone of a Coco 2 or 3 like the Replica I Apple I 
clone, or the clones of the Altair 8800 and other systems.

Once that is debugged and available, it could always be expanded with new 
features.

It doesn't have to fit in a Coco 3 case.

All the chips in a Coco 2 can still be purchased, or scavenged from a Coco 2 
with a bad keyboard, etc...

I remember seeing that someone reimplimented the GIME using discrete logic.

I won't spend a dollar on a generic FPGA board that requires giving up 
features or ports. Maybe I'm alone in this, but I want a reproduction that 
has all the same ports and expandability as the original.

Add a faster serial port dedicated to DW? Fine.

Add a PS/2 Mouse and Keyboard port that transparently works like the 
originals? Great!

Add a VGA or HDMI video out? Fine.

Add more RAM that can be bank switched in? Great!

But keep the cost low, so lots of people will buy one to play with old 
software again. Then, make a revision with new features, or include an 
expansion connector that will accommodate add-ons.

Just my .02.
