I posted this on Erik Klein's forum awhile back, but also meant to post
this here.
Electronics Goldmine has new 2-per-package MCM4517P12 16Kx1 DRAMs for $1
for two ICs. These are the single-supply version of the 4116 3-rail
devices and I believe, entirely pin-compatible.
Might be a good deal for someone looking for replacement DRAM.
