MULTI_8_Disp.jpg (77636 Byte)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.
