The TD4 TTL CPU is a very simple CPU to learn how computers work or just to hang on the wall to have a great and large (28,5 cm x 18 cm) blinkenlight LED display.

The TD4 computer contains 188 LEDS, has 14 instructions, 16 Bytes of programmable ROM (with switches), 2 clock speeds, step mode, 4 bits output and 4 bits input. At he left side of the PCB there are some connection available for those who somehow want to add extensions to the design.

We added a lot of LEDS to this design so you can see with every program step what is happening inside this CPU. You can program it yourself with switches which sets the program in ROM. These are just simple programs but you can have a lot of fun with this simple computer. At the back of the downloadable manual you will find the complete instruction set and some example programs to test the TD4. You will also find at the back the pinout of all the used IC's so you can see what connections the IC's have. We also advice those who want to learn the exact working of this computer to search Google for the datasheets of each IC to see how they work in more  detail.

This is a large PCB 28,5 cm x 18 cm and be prepared to solder a LOT of parts (more then 1800 solder connections!!). This is a KIT for those who have a lot of experience with soldering and have knowledge of electronics. It will take some time to solder all the parts in place.

This version of the TD4 CPU is based on the designs by Kaoru Tonami from his (in Japanese language)  book How to build a CPU.  ISBN-13 ‏ : ‎ 978-4839909864.

IC SOCKETS ARE NOT INCLUDED. If wanted you need:
4x 14 pin socket
9x 16 pins socket
1x 20 pins socket
