datasheets for 82S21 - Signetics 32x2 SRAM?

A gated full adder? (I had to look it up...). I have a data sheet which 
even includes a transistor-level schematic.

Prolbems are that I can't access the web or read CD-ROMs at my workbench 
where I do most of my designing (I prefer to design with real components 
and a soldering iron), and anyway, it's a lot easier to flip through a 
databook looking for interesting chips than to display a pdf (every 
machine I've ever used, including fast PCs owned by friends of mine, take 
a noticeable time to display a page from a pdf file. A lot longer than it 
takes me to glance at a page and see if it could possibly include the 
information I am looking for).
