Help identifying this stepper Drive

[Johnny_l3ravo]

I have three of these stepper drivers. They came in a box with three Pacific scientific Max Drive II 65 volt DC stepper motors. There are no markings on the board that would give away the model. I've spent hours searching Google image search eBay and all over the Internet to no avail.https://uploads.tapatalk-cdn.com/201...bbcbc9417e.jpghttps://uploads.tapatalk-cdn.com/201...07fc3ca1d6.jpghttps://uploads.tapatalk-cdn.com/201...2f5c9e432b.jpg

Can't help with the motor id but this page may help you figure out the wiring and try them out

They look very similar to the old ones on my 12 year old multicam m series. I sealed them out cos the caps blew. The ones I had were called United scientific or something along those lines. But mine were only 48 v
