DEC Unibus 4-SLU (ACT 10015000)

I posted about this board before and one or more people said they had one. Now I'm curious if anyone has documentation for it :) This is a 3rd party quad height unibus board and appears to be a 4 port SLU. The manufacturer is ACT, and the only part numbers I can find on the board are 10015000, 10015001, and 10015002. There are 4 rotary dials (my guess is baud rate), and one 10 position switch bank (priority & address?). I'm curious what all the dip switch settings are, can it start at the normal console address and thus replace an M7856, does it have an LTC capability, etc. Pinouts for the port (berg) connectors would be good. I can't seem to find anything about it on bitsavers or googling. Any pointers appreciated! Jay West
