Where to find memory ICs?

Have a working Intel Above Board Plus 8 with 2MB RAM and would like to populate it to the full 8MB. It will take 120ns or faster 1mbit chips -- but where can one find that kind of thing nowadays? Are those still commercially available or am I going to have to scavenge them from somewhere else? Manual lists acceptable part numbers like: Fujitsu MB81C1000P-xx Hitachi HM511000P-xxS Mitsubishi M5M41000AP-xx Motorola M5M511000P-xx NEC UPD421000C-xx NMB AAA1M100-xx OKI M511000RS-xx Samsung KM41C1000P-xx TI TMS4C1024-xx Toshiba TC511000P-xx ...etc but google searches haven't been very fruitful (that is, the pages returned when I search for IC part numbers don't return vendors with plain pricing/availability info). I just want a few tubes of these to populate the board, I'm not looking for a box of 'em :-) Any pointers? -- Jim Leonard (trixter at oldskool.org) http://www.oldskool.org/ Help our electronic games project: http://www.mobygames.com/ Or check out some trippy MindCandy at http://www.mindcandydvd.com/ A child borne of the home computer wars: http://trixter.wordpress.com/
