Tamaya is a well known manufacturer of navigation instruments. It has a website which gives the above production dates.
The website also gives details of how to use the calculator into the year 2000 and beyond. By entering the date as the 99th day of the 99th month of 1999 !!! it is possible to use it up to June 23 2007. A table to print out gives all the necessary conversions.
If this is too troublesome you can buy the latest model the NC-2100G.
This is also a very specialised calculator using dedicated integrated circuits. The fitted wooden case is evidence of the respect which Tamaya had of its intruments.
Production over the the 14 years of 1978 to 1991 is probably a record length of time for any electronic calculator of the 1970s. It is beaten by the Hewlett Packard 12C financial calculator which was introduced in 1981 and is still in production.
The Tamaya NC-77 appears to have been manufactured by Sharp - the casing closely resembles that of the Sharp EL-8018.
The Commodore N60 is a scientific calculator with 10 digits precision and algebraic logic. It has 100 functions, 60 keys, and a VFD (vacuum fluorescent) display. The power source is 2xAA sealed. The calculator was manufactured in UK.
