I take it Sonnet doesn't have a box of them sitting around somewhere? ;D

The Presto Plus processor upgrade card has an onboard RAM expansionSIMM slot with a 32 MB SIMM that adds additional RAM to your

system.
Way cool. Outside of the Radius Rocket, I can't think of any accelerators for Macs other than the Compacts with RAM on board. 32MB of RAM on the '040's local bus really would make the Presto Plus a workable upgrade for the LC. I'd love to know how they hacked the memory mapping, especially across that 16 bit bottleneck. It must be something like Compact Virtual? I see why you're keen to acquire one.

Notice, Sonnet included the 32MB SIMM on board. If they hadn't bundled it, customer service complaints and returns due to lousy performance would have been a nightmare. I wonder if it would work at all without it?
