You sure about that? I think we were paying more than that per 256Kx1
chip. In 1987, IIRC, when the Commerce Dept accused Korean DRAM manufacturers
of dumping, the price went from $3.50/41256 chip to $17.50. I had a 1.5Mb
Spirit "Inboard" for my Amiga 1000 - it would have cost me $1000 to fill it,
but I managed to scavenge an engineering prototype from the trash at work
that was partially filled with RAM... 50256 chips (ceramic package, MIL-SPEC)
for which the company paid $80.00 each a few years earlier.

SOJ is a surface-mount packaging. You almost certainly want DIP. Try
AmericaII Electronics - http://www.americaii.com/ I've bought from them
in the past. Caveat: not all my buying experiences were smooth, but I
would buy from them again.
