Photos from.

630 'DOS Compatible' model.

The 630DOS has a daughter-card plugged into its the normal '040 processor socket, and sitting on the daughter-card is both the '040 and a 66mHz Cyrix 486 DX-2.

Higher up on the daughter-card is the purple 68040 processor, towards the back of the mainboard is the heat-sinked Cyrix. The piggy-back card off the daughter-board (to the right of the two blue IDC connectors) is the Vibra16 sound card.

Upside-down beside the Vibra16 is the card the joystick port is off, and then closest to the camera, standing upright is the 10bT ethernet card.

.
It looks like (going on the motherboard diagram below, and the photo of the above machine's back panel) the joystick card is the one taking up the PDS space. Whether it connects to the PDS slot or not, you can't see from the photos. But just maaaybe, if you can do without a DOS joystick port, you could remove that daughterboard. Maybe.

You can see the small joystick symbol just under the port in the place where a PDS card would go.
