Guys, Please find attached latest art work for this board.
I've done away with the 14 pin dips and let the "Sea of PTH" flow into that area.
Power runs through it.
I mixed in the terminations for S-100 bus to the lowest 2 rows of of the sea.
Look at top right, I added a DB connector, less the DB mounting holes.
I think it would be very handy to have this option, one can always put an IC over top the skewed pins if they don't want DB9. I'll keep the DB9 there unless it gets voted off the island (or sea).
It looks like it's ready to go... 2 questions still loom.
1. Position of LED,
2. Size of holes (I reduced to .038 from .042... I'm now thinking that was a mistake)
