I believe I'm still down for two of these boards - delivered within Canada. Do you have a list made up of who's in? It's getting a bit difficult to keep track, because boards that are initially "limited run for those that can't wait" become "order now or miss it 'till next time". I don't want to miss an opportunity, especially on a board that may not be re-ordered soon.

Hi,
I'm ready to go for a run of these Mini-buffered Prototyping boards.
Shipping varies. But you have 2 options. I can ship up to 5 boards in a box from Canada for $16 (flat rate small package)
or you can wait until Mid-April, I can cross the boarder and ship in strong cardboard envelopes at Andrew's rates.
I want to get some pre-orders, before making the run.
Regards,
Josh Bensadon

I very much like what you'd done with the sea-flow.
Personally, I'd never put a DBxx directly on an S100 board. Instead use an IDC-type cable with a 2xN connector and ribbon . The DBxx belongs on the bulkhead. So I'm not enthusiastic about that change.
As for the LED, perhaps a placement consistent with what's used on the 80286 master/Slave CPU Board would avoid the (potential) card ejector handle. Or maybe just scrap it and let folks wire what they want, if they want anything at all? After all, they'll probably be bringing PWR/GND "around" for ICs anyway. So let them wire-where-they-will, rather than committing to that corner? (OTOH, they can always just cut the trace ...)

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)
Cheers,
Josh
