Sorry, my mistake I was thinking about Optoport not Uniport

I have used many Optoport boards but never used the Uniport.

Just took delivery of some PBB20 with the new spindle speed board for a couple of conversions that's on the books but these will have to wait until after the Warwick show.

In fact just got a parcel of goodies for the show from Roy today but not had chance to open it.
