The electronics is composed of only 3 ICs. Two Toshiba chipsets (T7812 & T7813) hold the Z80 CPU, the BASIC interpreter and manage the keyboard, display and printer interface. Strangely, each chipset manages half of the LCD display. The third IC is a 4 KB RAM 5116.

**(4)** 5116 RAM chip, here a Sharp version\

**(5)** Keyboard's rubber sheet. Each "bubble" corresponds to a key.
