I have a 1993 Unisaw with the 52" (?) Unifence table. The Unifence is, I think, the older style and was an option on the saw, a Jet Lock fence was still standard.
The table is skirted on all four sides with lightweight 1 1/2" angle. There is an 1/8" thick strap between the saw table and the wooden table, with attachments for the wood. On the other end is a two legged square tubing setup with adjustable feet. There is also a shelf underneath. The whole thing is solid enough to sit on.
I have cut mine down to about 32', but still retain the same shortened structure underneath, and it houses a PC 690 router setup for quick roundovers, etc.
Historical note: I paid $1831 for it in 1993, including tax and the optional fold down outfeed table.
I have the manual for the saw and for the table and shelf. The table/shelf setup is part number 34-998, the Unifence is 34-897, and the part number for the manual is 422-27-655-0007. My manual is dated 12-1-92.
Hopefully you can download the manual.
