Well, I've used 1x256-15 (256k, 150 nanosecond) memory salvaged off of
old 8088
motherboards, 16pin, on Apple 1 meg expansion boards and they work
fine.  I think what you have is a bit large, a bit too fast (70ns?) and
too many pins.  Wander over to IBM
comp.sys and ask around there;you might get someone to swap them for the
256k, 16pin 
memory that an older GS memory expansion board can accomodate.
