3.30 is included with the laptop. It is the first laptop with a swappable battery pack. Its original price was 6499 USD. The T1200's hard drive has an unusual 26-pin interface made by JVC, incompatible with ST506/412 or ATA interfaces. Floppy drives are connected using similar 26-pin connectors. The computer has many unique functions, such as Hard RAM - a small part of RAM is battery-backed and can be used as a non-volatile hard drive. Another function allows to suspend the system or power control the hard drive (which is still dependent on the hard disk's on/off switch). The Toshiba T1200xe is an upgraded model of this laptop, which contained a 12 MHz 80C286 processor and a 20 or 40 MB hard disk drive. It also has 1 MB of RAM expandable to 5 MB. The floppy drive was also upgraded from 720 KB to 1.44 MB.
