The DSUB parallel connector has been mirrored
on the PCB.  The schematic is correct.
Works OK with an adapter cable; or you can put
the connector on the solder side of the board.

Also P2 and P3 should be 10k, not 2k.

I just notified Octavio, but since he may be
celebrating Easter, I'm sending this letter,
in case someone else is scratching his head
a lot.

Happy Easter!
