What is it?

The "TTM8 Logic IC CPU Assembly Kit" is a construction kit for learning the internal structure of a computer.This CPU operates by combining only logic ICs. It is a practical 8-bit CPU capable of executing 16 general-purpose instructions. It features a pure circuit configuration that combines 44 general-purpose ICs, more than 100 LEDs to display internal signals, a hexadecimal keypad for easy-to-understand learning. The program can be configured with up to 64 commands and can perform various operations depending on how the commands are assembled. Students and working professionals who wish to learn about the internal structure of CPUs can learn the mechanism of CPUs from the beginning with a pure circuit,no any blackbox!

Key Features

CPU featuring pure circuits composed of 44 logic ICs

The CPU is composed of logic ICs with clear internals, so you can learn pure circuits without a black box.

More than 100 LEDs to display internal signals for stand-alone learning
Hexadecimal keypad from 0 to F for data entry when writing programs or referencing RAM

More than 100 LEDs display internal signals to aid learning.

In addition, a hexadecimal keypad from 0 to F is provided for data entry when writing programs or referencing RAM, allowing the kit to be used as a stand-alone learning tool.

Equipped with a 32-byte stack for storing user data and subroutine calls

Expandable self-made I/O for experienced users or those who wish to learn more by building their own expansion boards and controlling their own control targets with the TTM8.
