Specifically hardware from a company called <a rel="nofollow" href="https://en.wikipedia.org/wiki/Floating_Point_Systems" target="_blank">Floating Point Systems</a> (FPS), whose systems provide computing features to assist e.g. a minicomputer like [David]’s PDP-11/44 system with floating point operations. The goal here is to use a stack of 1980s-era FPS hardware to give the PDP-11/44 MIMD (multiple instructions, multiple data) computing features, which is a characteristic associated with supercomputers.</p><p>The FPS hardware is unfortunately both somewhat rare and not too much documentation, including schematics, has been found so far. This is where [David] would love some help from the community on finding more FPS hardware, documentation and any related information so that it can all be preserved.</p><p>FPS itself was acquired by Cray in 1991, before SGI took over Cray Research in 1996. As is usual with such acquisitions, a lot of older information tends to get lost, along with the hardware as it gets tossed out over the years by companies and others. So far [David] has acquired an FPS-100 array processor, an interface card for the PDP-11 and an FPS-3000, the latter of which appears to be a MIMD unit akin to the FPS-5000.</p><p>Without schematics, let alone significant documentation, it’s going to be an uphill battle to make it all work again, but with a bit of help from us retrocomputer enthusiasts, perhaps this might not be as impossible after all.</p><p></p><p></p>]]></description>
