I guess it could be cost-efficient to manufacture a general-purpose calculator chip based on Z80 than to manufacture two or more.
3.
Sometimes significant design effort is needed to fit all the desired functions in the limited memory space available in the calculator chip, with acceptable calculation time.

First, Mark had to redesign an existing calculator chip to include a display driver multiplexing scheme and a special sound driver for a piezo-ceramic speaker.
5.
Integrated circuits such as 1K-bit RAMs, calculator chips, and the first microprocessors, that began to be manufactured in moderate quantities in the early 1970s, had under 4000 transistors.
6.
MOS Technology's other business, calculator chips, was declining due to a price war with Texas Instruments so their financial backer, Allen-Bradley, decided to limit the possible losses and sold the assets of MOS Technology back to the founders.
