There was one worse: the one that came with the BASIC on the Atari 2600. And this was actually my first "computer" on which I wrote BASIC programs: an ATARI 2600 console. The BASIC cartridge was coming with some kind of keyboard controller that you'd plug in the 2600's joystick ports. It was horrible but it allowed to do simple programs and even draw colored lines etc. IIRC.
