TI-5010_Prt.jpg (51375 Byte)The TI-5010 - successor of the TI-5025 - is one of the early printing desktop calculators using normal paper. 

TI-5010_Lab.jpg (10532 Byte)It relies on Japanese components and manufacturing capabilities. The backside of the calculator states clearly "MADE IN JAPAN" and it is easy to locate its true genes.

TI-5010_IC.jpg (66075 Byte)TI-5010_PCB.jpg (71284 Byte)Dismantling the TI-5010 reveals immediately the Toshiba LC-1028PV as its sibbling. Fellow collector Stefan Klaes discovered recently in a TI-5010 a printed circuit board (PCB) with a short designation "EC-3009". This magic number leads to a Radio Shack EC-3009.

Compare some other TI calculators with their sibblings manufactured by Toshiba.

The TI-5010 sports the "office grey" design of other products. 

The desktop line then covered 6 different calculators:

TI-5008    Pocket-sized, thermal printing
TI-5010    Small-sized, standard paper
TI-5032    Desktop-sized, battery option
TI-5130    10-digits, standard paper
TI-5142-III 12-digits, standard paper
TI-5020    Non-printing, solar powered

Five years ago with the TI-2800 Paperless Printer a new concept of small desktop calculators was introduced.
