The company name is "CDS INC".

Century Data Systems, a Xerox company?

That would make sense, but given that they went to Xerox in mid-70's , why would they put their own name on a product that's roughly mid-90's? (judging by the IDT winchip that came out probably in 1997)
Still, that's the closest we've come to figuring out what it is. CDS was in fact a storage manufacturing company so an accessory that works out of SCA bay makes total sense...
