I had a 2600 back in the late 70s, but never knew that they had a BASIC cartridge. That must've been one helluva limited programming experience considering how limited the 2600 was for game programmers writing in Assembly.

It is. Here's a picture of what it looks like (http://boston.conman.org/2015/06/14.1) and I even wrote about my experience in using it: http://boston.conman.org/2015/06/16.1

The executive summary: it's both incredible (it has features I've never seen elsewhere) and horrifying (wait until you see the keyboard, and you only have 64 BYTES for everything).
