AMI chips; any info?

I have three types of chips, in the quantities listed below, that I have no idea what they do or what they are used in. The nearest I can speculate is that they are for the Fairchild F8 processor. Anyone have additional info? I can also donate these if someone has a pressing need... Manufacturer is AMI and date codes are 1977 - 1982 QTY #Pins Part number --- ----- ----------- 4 40 S2350 5 28 SW20365K 16 28 SW20417K If the two "SW" 28-pin jobs are "house numbers" and I can't find a reference, I'll most likely pitch them...
