These oddball 22-pin DIPs of middle-size width (3/8" x 1-1/8") is part of a collection of components my father bought in his you with the intention of building his own computer. (from a bunch of TO-100 components, maybe shift-registers? Plus these ram chips)
Fortunately, there were almost enough matching sockets to put all of them in sockets. But I can't do much with them without a pin-out and size/speed information.
I've been looking here but finding nothing: http://www.bitsavers.org/components/national/_dataBooks/
Anybody got a lead on info?
