[Coco] 4 Port MPI PCB artwork (so far)

Looks great!

Current spacing is fine by me.

Also, fine by me.  Could the profile be lessened by installing caps with
leads bent 90 degrees?

LEDs and switch could be extended by leads, either by soldering in or via a
header, and be placed anywhere to suit a case design or user preference.
*If* there are free lines on the two IDE cables, they could feed those
signals back to headers on the buffer side - this could allow selection
nearer to the CoCo, buffer board case or even a CoCo case mod for those who
like that.

>  * One of the designs had an cart autostart disable.  Is that of interest?
>  * Another design had a reset disable.  Thoughts?

Both could be useful.

Thanks Jim...

- Were the ears also good (or more solid) ground points?
- Extra mounting holes?  For slots and buffer side.
- Jumpers to select input power type?
- Perhaps shift components to one board edge?  That would provide a
standard placement for cases, etc., and leave board room for any possible
"on board" carts in a potential future revision for common functionality.
