Sounds like doing this will let out the magic smoke in a hurry.

Do you think they've fused it so it doesn't short out and trash any board you put it into by mistake?

Seems unlikely. Fuses, MOVs, and clamp diodes cause signal integrity issues (especially at 3.3V and under). And, for 200 lines, the cost might be impressive.

That said, if the Pi foundation can arrange for all the I/O to come out of reset in a hi-Z state, then there's a chance they could arrange the rest of the pins to avoid damage.

But would it be worth the effort? Given how hard it is to access most sodimm sockets, mistakes seem rather unlikely.

It's like how people used to mistakenly plug their modem phone cord into a PBX jack and fry their modem because the voltages were way higher.

Having it show up as an unrecognized DIMM would be clever, but perhaps not worth the trouble.
