This
Toshiba BC-0811B combined the keyboard technology of the BC-0808B
with the housing of the BC-0804B and started the era
of basic calculators with a fully independent memory.
The
BC-0811B seems to be one of the first portable calculators with an integrated
memory, Texas Instruments followed in 1974 with the TI-2550.
Inside the BC-0811B we discovered a Rockwell R15330PB calculator
circuit manufactured in October, 1973.
