You probably have 18-pin 64k x 4 (=256k bit) chips, and need 16-pin 256k x 1 chips. I believe the 16-pin package is quite standard for 256k x 1's in a standard dip package. > > Also, ads in Computer Shopper suggest prices are in the $10-$13 range. > However, the ads don't indicate the number of pins, just the speed. Can > anyone recommend a cheaper/good source? I have some chips removed from boards (or boards w/mounted chips) I would like to dispose of at about half the upper end of the range you mention. They are 256k x 1, 150 nS.
