Photo of an (almost) square LED panel display with green LEDs illuminated in what can be seen to be a pattern representing a stage of Conway's Game of Life.

Photo of a cheap TD4 kit with some added LEDS. There are two 6-LED modules added on top of the A and B register chips, and four additional individual LEDs soldered onto the underside of the board just poking out on the right, one for each row of ROM instruction DIP switches. Some of each of the LEDs are illuminated along with the existing LEDs for the OUTPUT register that are built into the original board.

Photo of a fully populated TD4 PCB. There are 16 blue 8-way DIP switches in a 4x4 grid, each with a corresponding 8 diodes - yes I really had to solder 128 diodes. There are 13 ICs, a few resistors and some miscellaneous components.

Photo of a rc2014 and a HDMIPi display with a small solderless breadboard inbetween with a single chip on it, connected to both via jumper wires. The RC2014 is on and the display shows the boot information showing that BASIC is running.

Photo of a small devboard with a USB-C connector, a 0.42" OLED display, two rows of 8 pins and a couple of buttons. The whole board is less than 30mm square.
