Ah, the good old Atari 2600 Video Computer System [3]. It could only address
4,096 bytes of ROM (Read-Only Memory) and 128 bytes (not megabytes, not
kilobytes, but bytes) of RAM (Random Access Memory), and as far as graphics
are concerned, the Atari 2600 is responsible for drawing every pixel on the
screen, as the screen is being drawn by the eletronic beam on the television
[4] (or in other words, you are _Racing the Beam_ [5]).

It's not an easy machine to program.

So to even contemplate BASIC (Beginners All-purpose Symbolic Instruction
Code) on the thing is insane. But it exists [6]. And it has that oh so very
sweet Atari cover art:

[The necktie is a bit stiff, but man, look how fun this computer system is!
Buttons and blinkenlights everywhere!] [7]
[8]

followed by the dismal reality that comprise most of the Atari 2600 programs:

[Where are the shiny red buttons? Where are the blinkenlights? Where are the
oversized arm watches?] [9]


Still, I find it a fascinating system. Like Hughs Johnson [10] says, you
could Tweet most Atari 2600 Basic programs they're so short. And because the
language is so constrained, it seems like one could easily randomly generate
scores of valid Atari 2600 Basic programs.

Hmmm … I have yet to figure out what my next Stupid Twitter Trick™ [11] is to
be …
