[GreenKeys] Jack (K2TTY/K0TTY) Hart's Motor Control Board

[Gerry]

Sounds good.  
I’m not sure why the base connection is brought out but I suppose it could be useful for test or other logic functions.

And Nick, K4NYW, sent me some scans of the top and bottom of a bare board so that I could confirm the fact that there was no connection to pin 6 of the H11D1.  Have only used Jack's board an not having done any design work with an opto-isolator, I would have thought there would have had to have been a connection to pin 6.  Without a board handy to refer to, I was assuming (I know!) that the board would have a connection and that there was an error on the schematic that had remained undiscovered all these years.  I guess my breakfast this morning could be the egg on my face! 🙂
