here it is.
..the first from toshiba is in full working condition...unfortunally no any ceramic inside but is too old....and with full accesories 
the second from Canon "Pocketronic".....looks ok...but no ac adapter to test it...
use only a thermal tape to dispaly data ...
im surprised with the white old Beauties inside
hope u like it.....

Nice TI chips Kosmo. Congrats!
The only problem with calculator chips is because they are almost always soldered  |

the Zebra TMC173x is nice
by the way,
according to the Ti datasheet
there are 3 Ti prefix (TMX,TMP,TMS)
prototypes
TMX: experimental
TMP: prototype
------
qualified
TMS: qualified
i cant find TMC mean
does C stand for
customer or something else (caculator?) |

there was other TI chips marked TMC that were not calculator chips.
one was the TMC0280... the first one-chip LPC speech synthesizer used mainly in toys
Im guessing it was early TI marking for ceramic ICs
