He swears its true. Never heard of one myself and I have even owned about 15 IIfx's over the years. I wonder if he has a Stage II Radius Rocket and classifies it as a dual processor machine.

Okay, here's my guess. The seller doesn't have a clue. He looked under the hood and saw the 68030 and the 68552 (? FPU) chips which look similar if slightly different in size. Then assumed that the presence of two such prominent chips meant that it has two processors.

That's my totally foundationless guess.
