That's probably why you got a warmstart (and likey WSLOG shows a module pulled message). Card slot 1 is identical to both card slots on the HP48SX, whereas card slot 2 is not.

Good call, an important distinction. And if it works in a GX/Port-1, it could possibly work the same in an SX, unless it uses some of the GX extensions (implied by the items found in the disassembly), but seems unlikely if it was marketed as also working with the SX as described in the mktg blurb quoted above. It's possible that the latest version of Super Switch only supported the GX since most users, likely to need such a card, probably had switched to GX machines.
