I first went deep on programming learning Z80 assembly for my TI-83. It has a lot of idiosyncracies, such as 8-bit registers that can be combined for 16-bit operations. But it was a lot of fun learning from tutorials and from reading other people's code. It put me way ahead when I got to college, as I had already learned a lot about computer architecture.
