Go look at www.tyan.com & www.asus.com, and you will see that they
exist, I've even had one in my hand (don't know what make it was though)

Nope, not exactly, the PII was first used with the 440FX (natoma) P6
chipset, and that works..
I havn't looked at the specs though, but given the extremely simple
layout of the Socket8->Slot1 adapters, I'd say Intel just took the
P6 pinout and put it on an edge connector instead, well, more or
less. As I see it, Slot 1 was not made due to technical/egineering
problems, its just sheer marketing (remember the 486SX & 487SX
story some years ago), and its lots cheaper to produce...
