The TI-62 Galaxy is a quite interesting calculator within the Galaxy-line. In addition to the functions of e.g. a TI-37 Galaxy it adds the programmability of a TI-57-II. 

From the technology use this calculator is a unique composition:

Housing similar to the Galaxy
Keys like the later TI-68
Calculator chips from Texas Instruments, not Toshiba

Galaxy62_PCB.jpg (568001 Byte)Dismantling this TI-62 Galaxy manufactured in July 1987 by Texas Instruments in Rieti, Italy reveals a rather complex design based on a two TP0485 Microcontroller used in a Primary-Secondary Architecture known from the second generation slanted TI-60 calculator introduced in the same year.

One year later Texas Instruments introduced the black TI-65 Technical Analyst using a dark grey housing.
