Thanks for confirming what I thought for the reset connections.
Looking at the PCB it seems that the pins placement for the opto-isolators are neatly aligned so I can us a strip of SIL sockets to mount them, and not have to use 4 pin sockets, although they are cheap enough to just solder them
Did you have a special foot print in the design tool to do that or was it just careful placement of the opto-isolators?
