I just had to try it and it works.
Reminds me of my early programming days when I was the proud owner of a Commodore PET (I still have it).
So now I am thinking of scaling this casing up, placing an Oled screen in the display and some Neopixels up front. I'll add a Dallas 18B20, a buzzer and some leds and have all I/O pins accessible from the outside. Would make a great experimenters kit, or even a gift for the upcoming season......
Oh, I bought 8 kilo pink PLA for a fantastic low price (below 20 USD). However now I need to print most of my projects in pink......
