Display is 8 digits red LED (made by Bowmar).
4-function, %, memory.
Has [M], [C/CE], and [%] keys.
Battery: 9v (PP3 battery). The PP3 battery is thicker than the AAA batteries normally used with Cambridge models. Two-piece smooth red plastic case which is designed so small that the 9V battery compartment protrudes out an extra 5mm! A raised escutcheon frames a deep purple display filter that gives quite a good, if narrow view of the digits. The keyboard surround is in contrasting black plastic. The white keys are short travel and give a prominent click but work well enough. The company and calculator name are printed in black text above the keyboard. Palm-sized calculator that can only be used in the hand and not on the desk due to the protruding back section.
Main integrated circuit: Mostek MK-50321
Size 50 mm x 111 mm x 28 mm.
Made in England.
