Quoted from pinballinreno:I can confirm that the Homepin POA boards that PSP sells dont work at all.
A total failure.
I bought 3 of them and PSP is dead quiet about replacing or refunding my money...
I bough 2 different ones from Marco. They work perfectly.
Oddly the 10 opto board I bought from homepin for my Doctor Who is very good and seems very robust.
This is a known issue with early run homepin boards. It just needs a resistor change.
Contact [email protected] directly for details of resistor values if you have the resources to do it yourself.
"Dead quiet" is a sad irony. Mark passed away a couple days ago mate. Please allow some days.
you're welcome to pm me your email directly if you want me to get it dug out as a priority but the easiest way will be fix resistor under mikes guidance.
