Cambridge Digital 11/73 system questions

Greetings; I have a Cambridge Digital "94/23-70S" that I'm trying to bring back to the land of the living, filled with cards I can find little information about. I was hoping someone might be able to point me in the right direction. QBus cardcage with: Chrislin Industries CI-1173-EDC Emulex SU0210401 Technical Magic Inc 4S I think it's fairly clear the Chrislin is an 11/73 SBC, I know the Emulex is an SMD controller, and the 4S is a four-port serial card. I can't find manuals on either the Chrislin or the Emulex, and although I can't find a manual specifically for the 4S 4-port serial card, BitSavers has one for its bigger brother - the 8S 8-port card. Hopefully they're close enough. System also comes with a CPI tape drive (BY5A3-B) and an 8" Fujitsu M2312K. I'd really like some PSU pinouts so I can test it prior to plugging the cardcage in and seeing if it works. The boards are also covered in a fairly thick layer of mold, which is something I'm not used to seeing. Trying to decide what I can use to safely clean them - possibly Isopropyl, a QTip and some patience. Any help would be greatly appreciated; - JP
