Additional Pictures 


The internal view of the TI-30 PLUS SOLAR manufactured
in Japan looks very familiar to us.

Please use the huge solar cells still used with a
calculator manufactured in 1987.

The Toshiba T6974S single-chip calculator circuit  
found in the TI-30 SOLAR PLUS.

With a manufacturing code dated July, 1987 this 
TI-30 SLR PLUS seems to be one of the last 
calculators assembled in Japan.
