Apple II card info needed

All: Today I received three Apple II cards for which I'd like to get some info/manuals on. The first is the "Synch Printer Interface Card" which I believe is for the Silentype printer (It has a 9-pin DE9F on it). The second is an Apple-labeled 12k ROM card with part number 960-9104. It has six sockets and appears to be ORGed at $D000. There's a jumper labeled "2716" and a small red toggle switch. Maybe it can program EPROMS? Five of the six slots are filled with Apple ROMs - the D8 ROM is missing. The third one is from Xebec Systems and is labeled "Apple Host Adapter". It has a 50-pin 0.1" header along one side. No custom silicon (only an EPROM). Given the manufacturer and pin header, I'm guessing SCSI. Any info greatly appreciated.
