[Coco] MC6847 External ROM REV02

I was able to clear my kitchen table and setup a Coco 2 to test which is now 
running the Saturn RAM Checker Cartridge.

I just dug out the Coco 2 with the Lowerkit. I'll take pictures of the 
screen tomorrow having swapped the character set ROM from the TDP-100.

I'll look for my cassette cable, and see if I can use my Intronics Burner or 
my Color Burner to dump the Character Set ROMS to tape, or a .wav file on my 
laptop. But no promises. Without someone helping me, it's going to be 
difficult to maneuver things on my tiny kitchen table. And, the last time I 
burned an EPROM was in the late 80's with either burner (and it was an ADOS 
which is pretty easy).

I'm still repairing my extra lowerkit.

Yep.  :)

It will support either 27128 or 27256 ROMS for 8 or 16 character sets.
I have a couple of extra dip switches on this one to experiment with
inverse mode, mixed character sets etc.

We can see what kinds of nifty fonts we can come up with!  :)
