The Galaxy 9
is almost identical to the Galaxy
9x introduced one year earlier. The only difference is one key, we know
similiar sibblings with the German Galaxy Junior
and the French Galaxy 10.
The first design of the Galaxy 9 - introduced already in 1991 - received after two years a slightly changed color scheme. The pictured Galaxy 9 was manufactured in the year 1995 and still available in 2002 at an airport shop in Lisboa (Portugal).
the Galaxy 9 reveals a small surprise, the calculator is 100% identical with the Galaxy 9x.
The Toshiba T6A60 single-chip calculator circuit found in this Galaxy 9 manufactured early in 1995 reads a Texas Instruments part number "1111273-4021", probably a ROM-Code identifier of the embedded software.
The spirit of this calculator was repeated with the TI-15 introduced in 1999.
