This is a small Toshiba laptop computer. It is rectangular and beige and grey in colour. A purple moving sticker has been stuck and partially removed on the lid of the object. On the rear of the laptop, there are several different electrical connectors, some of which are labelled, and a small hole labelled “RESET”. On the right hand side there is a slot for a 3.5″ floppy disk and above that two small scroll wheels inset into the side of the machine. On the left side, there is a metal connector and a depressable button labelled “POWER”. On the base of the laptop there are small ventilation holes in one corner, a cover labelled “EXP.MEMORY” and a silver sticker which includes model information about the computer.

Paired latches on both the left and right sides of the computer (on the lid) allow it to be opened.

Opening the lid reveals a rectangular screen 19.5cm in width. Beneath this, there is a row of seven indicator lights, each labelled. There is a standard QWERTY keyboard located on the lower half of the laptop.
