Any interest in a Floating Point Systems AP-120 array processor?

I'll say. Modern kit gets 1 FLOPS per MHz per core, give or take an order of
magnitude depending on the specific architecture. That machine must have
been appallingly bad to only manage 30 MFLOPS. Although perhaps you meant
GFLOPS, in which case it sounds about right.

The Haswell CPU in my 2014-vintage laptop manages "up to" 147 GFLOPS. Which
is an order of magnitude slower than its GPU. Useful FLOPS for scientific
computing rather than contrived numbers for benchmarking may well lose an
order of magnitude or two in overhead, but it's still not hanging about.
