[cctalk] IDT 49C402BG84 Pinout?

Hi all, I'm dreaming to build sometimes my own Bit Slice CPU (when I have spare time) and I have collected several IC's in the last years for this purpose. Today a small antistatic bag with 4x IDT49C402BG84 and two IDT 49C410J fell in my hands while I was sorting some stuff. I know what they are and what they could do, they are able to help me to build a Bit Slice CPU w/o very large PCB's connecting hordes of 2901 etc. Besides of that they are CMOS and should draw much less power. But I have a problem with the 49C402: All datasheets that I could find until now, don't have the pinput auf that nice PGA84 package, there are DIP68, LCC/PLCC68 G68 or PG68 and QE68 "Cerquad" pinouts listet in every datasheet, but I have 4 chips in a PGA84 housing... This ebay page has pictures: https://www.ebay.com/p/10020043211 I don't have anything todo with the seller. Can anyone help finding the pinout? The chips itself don't seem to that seldom...
