Xebec SCSI Card

[louiss@gate.net (Louis Schulman)]

I have a Sider with a Xebec SASI card (works fine, btw).  I also have what
appears to be a Xebec SCSI card.  It is newer (1989), has a 50 connector
flat cable running to a female db25, and looks altogether like a SCSI, not
SASI, card.

My question is, what drives can I use with this card?  Any Apple compatible
SCSI?  What software, if any do I need?  Will this card support the old 
Sider SASI drives?  What else can you tell me about this card?

TIA
