🇳🇱 Gigatron TTL Computer: Part 1 [TCE #0547]
61Let's have a look at this interesting CPU-less computer designed by a pair of Dutch engineers (sadly Marcel passed away in 2020). It has 32KByte of RAM, a 128KByte ROM and a bunch of 74-series logic chips.
Video output is 160x120 pixels in 64 colours (🤯) via a VGA connector. It uses a DE9 port for input/output (i.e. game controller or loading software), has a 3.5mm jack for sound output and uses a Mini-USB port for 5V power (I mistakenly said "micro USB" in the video, picked up by @SamuelFlint, thanks!).
I got the kit in 2018-2019 so it includes the wooden box and has the v3 ROM - latest appears to be v6 which includes support for a bunch of upgrades, including 128KByte of RAM and SD card interfaces apparently.
I need to build the Pluggy McPlugface adaptor which adds Tiny BASIC and a PS/2 style keyboard socket.
