Those were definitely "top shelf" in the day.

That's *much* cheaper than they would have been, say, in 1986 or 1987...
see if you can find an ad willing to _quote_ prices (most will say
"$CALL")but I remember when the U.S. Dept of Commerce was leveling
dumping charges against Asian DRAM vendors - the on-the-street price of
an ordinary 41256 (256Kx1) went from $3.50 to $17.50, virtually overnight.

But then, I also remember when a later ripple in RAM prices took a 1MB
30-pin parity SIMM from $25 each to $45 each (fortunately for me, I
bought my AMD 386-DX40 + 4MB at the old price - $150 for motherboard
and chip, $100 for the RAM). 1988, IIRC, maybe a little later.


If the boards you are looking at used SIMMs, not DIPs, they are much
later in the evolution of the product. By then, they would have been
used as a last-gasp upgrade of an old machine; new machines would have
taken SIMMs on the motherboard (and probably wouldn't have had a 286
chip, either ;-)
