It was equipped with an Intel 80C86 processor at 12 MHz, 1 MB RAM expandable to 5 MB of which 384 kB could be used for LIM EMS or as a RAMdisk, CGA graphics card, one 720 kB 3.5″ floppy drive and one 20 MB hard drive (Some models had two floppy drives.) MS-DOS 3.30 was included with the laptop. It was the first laptop with a swappable battery pack. Its original price was 6499 USD.

The T1200XE’s hard drive had an unusual 26-pin interface made by JVC, incompatible with ST506/412 or ATA interfaces. Floppy drives were connected using similar 26-pin connectors. The computer had many unique functions, such as Hard RAM – a small part of RAM was battery-backed and could be used as non-volatile hard drive. Another function allowed to suspend the system or power control the hard drive (which was still dependent on the hard disk’s on/off switch).
