This is a digital clock only made with logic chips. It features the RTC-74212A real time clock chip to count the time. The clock features a 2032 battery holder to continue counting the time, even when primary power is disconnected

It's a very simple design, only using 7 chips and only using trough hole components. The total cost of this kis is at time of writing (April 2026) only 21€! So it's a very affordable kit for everyone to assemble.

This kit is aimed at beginners, who want to learn basic electronics and soldering. I've also made a rich documentation for the kit, to explain how it works, how is can be assembled and troubleshooted.

This is a computer, fully constructed from >>off the shelf<< logic chips. No microcontrollers and or FPGA's are used.

The computer features a 65c02 CPU and up to 1MB of RAM. The computer can operate at up to 10MHz. The board also features the capability for the CPU to multithread.

The video card is constructed with only 24 logic chips and a RAM chip. It features two seperate modes, a textmode with a modifiable characterset, and a colored bitmap mode. The effective output resolution of the card is 384x256 pixels. The card can display 16 colors with the possibility of mixing more together using accent-colors.

This project currently still is in development with revision 2. Revision 3 aims to be the final release version. While kernel development has started, it's no near finished and will take some time. The goal for this project is to create a semi-graphical-user-interface with mouse controls and multitasking.
