Galaxy67_BACK.jpg (410196 Byte)Texas Instruments introduced with the Galaxy 67 in 1992 a calculator based on a very powerful microcontroller in the package of the Galaxy 9x and Galaxy 40x. The user might configure the overall memory of 1536 bytes according to his or her requirements.  Compared with other "Formula programmable" calculators this beast uses both the formula method and traditional programming. 

If you are interested in the calculating accuracy of scientific calculators don't miss the Calculator forensics.

Galaxy67_PCB.jpg (77150 Byte)Dismantling this innovative calculator reveals a big surprise! The complete electronics is based on a TMP0620F single-chip microcontroller sporting 1536 Bytes of user memory, scanning the keyboard and driving a dot-matrix display. Any ideas about other products with this hardware? Don't miss the PS-2400!

Galaxy67_IC.jpg (136916 Byte)The TMP0620F Application Specific Microcontroller is based on Toshiba's TMC17C architecture, a rather simple 4-bit kernel. Unfortunately is no further information of this interesting chip public available.

Don't miss a rare version of the Galaxy 67 sporting a yellow LC-Display.  

A similar calculator using a more traditional housing but less memory was introduced in 1989 with famous TI-68.
