My first exposure to computers was this strange bit of equipment: https://de.wikipedia.org/wiki/...
Oh my God, I'm feeling old! :-)

Unfortunately there isn't an english wikipedia page... What exactly is that?
(I barely remember floppys)

Well, basically it's a computer extension for a children's electronics kit sold mainly in Germany. With the electronics kits you could build circuits, up to your very own self-built radio receiver. And then there was this CP1. It contains a 6 MHz Intel 8049, memory for 128 commands with operands, using some pseudo machine language. All commands were entered in decimal numbers. Strange to see this now, I really thought about this for the first time in years after seeing this week's devrant topic. A blast from the past.
