796M
 
976M
Model 796M serial number 111715 Commodore Personal Electronic Calculator - Minuteman 76 Series.   Model GL 976M serial number 039565 Commodore Solid State Electronic Calculator - Custom Green Line.
Made in England in 1976, the 796M has a red LED (light emitting diode) display with eight digits. This one has its box and instructions, the latter describing it as a Personal Mini Computer. Uses a regular 9v battery and still works perfectly, although you have to hold it at just the right angle to see the display.   A rechargeable portable electronic calculator made in Japan, the 976M is a rechargeable calculator which can also be used while connected to the mains. It has a green, seven digit LED display. This example also has its box and instructions but the charger is missing and the battery no longer holds a charge. However, it works fine with a substitute power supply.
887ND
   
Model 887ND serial number 31043 made in Hong Kong.
Dating from 1979, this red LED calculator cost £3.95. I have the box, instructions and receipt. Like the 796M it uses a regular 9v battery and still works perfectly, although again you have to hold it at just the right angle to see the display.  
Commodore's first step into the world of consumer electronics was the pocket calculator. The components eventually became so cheap that the market was saturated and there was not enough profit to go round. It was at this time, in 1976, that Commodore took over chip manufacturer MOS Technology leading to the development of personal computers.
