[Coco] CoCo bus interface project

[Matthew Stock]

It *almost* worked for me without using the composite sync board, but not
quite.  If you think it's a sync problem, I'd start there.  The schematic I
reference for the composite sync is dead easy to make - I used the 74HC86
for the XOR - don't know if the HC would make a difference vs LS in this
circuit, though I wouldn't think so.
