>From what I have seen boards of the vintage that would have the chips I am
looking for (256kx4) are either in somebody's parts bin (which is why I
asked here) already or have been scrapped a while ago. Most of these chips
haven't been used since the early 90's making them at least 10 years old.

Some other oddball chips I am looking for are 256kx8 VRAM 70ns SOJ for my
old matrox vlb card (most boards use higher density vram chips).
