Due to massive amounts of caffeine & sleep deprivation, Allison J Parent said: No, the screensize of the M102 was the same as the M100, 40x8. One of the revisions on the logic board was a change from the proprietary 8K expansion modules on the M100 to just 8K SRAM chip sockets on the M102, and I think it was about 1 pound lighter. The expansion bus is also similar to the T200 (40-pin dual-inline 0.1" header) instead of the M100 (40-pin DIP socket)... AFAIK they have the exact same ROMS and run all of the same programs... but my experience is with the T200 and T600........
