This Toshiba BC-0808B demonstrates the huge steps from the first Toshiba calculators BC-0801B and BC-0802 to the handy pocket calculator. All dimensions and the weigh were reduced but the functionality kept. 

BC-0808B_PCB.jpg (169168 Byte)If we compare the internal construction with the BC-0802 we find the reasons easily:

The keyboard is a much simpler construction
The display driver were integrated into one circuit
The display uses one multi-digit tube instead the 
single tubes

Don't miss the BC-602L with a narrow 6 digit display and the BC-0811B combining the "old style" housing with the "modern" keys.
