National was handing the chips with manuals out for free at on WESCON--I got mine there, built up an S100 board with all of the interface logic (I think the PACE was originally PMOS) and never could really get the thing working reliably. It wasn't clear to me, after all was said and done that PACE offered any substantial improvement over the 8 bit chips. A later version used standard TTL levels and should still be findable--and a lot easier to put into a design. One thing that NSI could be depended on for--absolute volatility in the choice of design du jour. --Chuck
