1975: Commodore GL 976MD

Description	:	There is a page on this at http://www.vintage-technology.info/Pages/calculators/commodgl976m.htm but it's not too easy to get more information on it really... I am guessing by the model numbers of the calculators around it (the 879D came out in 1975) that this is a 1974 or 1975 calculator.
