Actually have a coupla parts hanging around, from the period where it
was new enough they'd hand out samples to anyone passing themselves off
as a researcher ;) Think I've got a meg or two of the second-generation
stuff (and another 64KB of first-gen, but the read/rewrite life on that
is specced an order or two of magnitude lower.)

Had the notion to use old cache SRAMs as a 1:1 write-through cache to
keep wear to a minimum; just haven't gotten around to *doing* it yet.
Well, oneathesedays...
