This LEM article offers a rather unflattering view of the card, and of its RAM disk capability, but I wonder if this could perhaps be related to the System software (7.5) under which it was tested?
Among the distinctly odd things about these old pieces of hardware is the disconnect between price paid and longevity; a parallel to this would be a nubus card like the 8/24GC from Apple itself, which was supposedly designed specifically for the IIfx (and its little bother, the IIci), both of which machines were designed with a view for the impending release of System 7. Yet the RISC processor and (in effect) separate OS included on the 8/24GC only works properly under System 6.
So you invested heavily ("It costs the eyes out of your head," would be a suitable French idiom for it), only to have a failure of support just a year or two later.
