1Mx4 DRAM 20-pin dips

I'm searching for a source of a DRAM memory IC that would have the following specs: 20-pin DIP DRAM memory chips (16) 1meg x 4-bit dips make up a bank of 8mb. Should be 60-ns Fast Page Mode non-parity An example would be Toshiba TC514400AP-60. Other manufacturers might use the following base part numbers: Fujitsu MB : 814400 Goldstar GM : 71C4400 Hitachi HM : 514400 Hyundai HY : 514400 Micron MT : 4C4001 Mitsubishi M5M: 44400 Any idea where I could find these would be appreciated. I'm even up to pulling the DRAM from some old boards, if I can find someplace that has boards that contain these chips. Maybe an old printer buffer memory card or something. Certain Epson ActionLaser printers contained the correct chips. There's some surface mount versions that won't work, and there's also a 26/20-pin version that won't work. These incorrect dips would have 20-pins, but are laid out in a 26-pin configuration with 10 pins on each side, separated by a small (3-pin) gap on either side. These seem popular, but unfortunately, they won't work! Thanks! Keith
