UltraPort

IBM UltraPort The UltraPort is a tiny connector sitting at the top edge of the display. It was introduced by IBM with the T20 series and other models of that time, but only continued onto some models from the time of the A31p. With the T30 type models it has vanished completely again. On the controller side the UltraPort is nothing but a USB 1.1 port, so all UltraPort devices are usable on other computers as USB devices as well.
