This is a revised model of the original T220. Notable improvements include using only one power adapter instead of two and support for more screen modes. However, power consumption increased from 111 to 135 watts (111 to 150 at maximum.) They were initially available as 9503-DG1 and 9503-DG3 models. The 9503-DG1 model came with a Matrox G200 MMS graphics card and two LFH-60 connector cables. The 9503-DG3 model came with one cable connecting from one or two DVI ports on the graphics card to the T221's LFH-60 sockets.
