The
Canon Palmtronic MD-8 was the first pocket calculator using a two-line display.
The upper display is the usual working display while the lower line shows the
memory content or intermediate results.
The innovative electronics inside the MD-8 is based on the TMS1000
Microcomputer family. The TMS1079 found inside the
MD-8 is similar to the
calculator Integrated Circuit of the TI-2550-II.
The related Canola MD 810 uses similar electronics in a desktop style housing. Within one year Canon replaced the power-hungry VF-Display with a modern LC-Display and introduced the MD-81.
