I still have a TI-86 somewhere gathering dust. That had a BASIC 
interpreter built-in. Somehow IIRC we also had a version of Mario 
running on it, I assume you could also run assembler on it somehow.

In fact I wrote a simple "shoot the target" type game in BASIC for a 
piece of GCSE Maths coursework. It showed you a target (a pixel) on the 
right edge of the screen, and you had to enter an angle and speed to 
fire an arrow (another pixel) to hit it. I learnt two important lessons 
doing that. Firstly to test your program with sufficiently varied input 
before releasing it, and secondly that 45 radians roughly equals 45 
degrees (mod 360).
