Chrislin docs?

Hello Everyone, I just got (from Chrislin no less!) a Chrislin Q-bus based floppy controller called a "Flex02". This was from a clean up they did and they have _no_ documents. Apparently there was a large fire that destroyed most of their archives. My contact at Chrislin said it "emulates and RX02 and the indicated jumper specifies 'boot rom' enabled or not enabled." Which is fine except what he didn't know is whether or not the 50 pin connector expected to go straight to a pair of 8" floppies or to a breakout board ala the RQDXn series. So... if anyone has docs on this board and could tell me what I need to hook it up I'd be grateful. This is what is on the board: Dual wide Q-bus, w/Z80A on board and some ROMs for the Z80. ROM labels are: 390028 01 P 390029 01 R 890012 01 M 890013 01 K Edge of the board says (c) 1980 "Flex 02" Rev 5 Back (solder side) says ICIM94V1 It has a 50pin edge plug and ahead of that plug is an NEC 8255 (this is a parallel port so it suggests to me at least that there might be some "off board" intelligence required. No sign of a floppy controller chip. --Chuck
