The Toshiba T1200 was a laptop manufactured by the Toshiba Corporation, first made in 1987. It was an upgraded version of the Toshiba T1100 Plus.
It was equipped with an Intel 8086 processor at 9.54 MHz, 1MB RAM of which 384kB could be used for EMS-Memory, CGA graphics card, one 720Kb 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. The T1200'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 memory 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).
