The Boston Diaries

The ongoing saga of a programmer who doesn't live in Boston, nor does he even like Boston, but yet named his weblog/journal “The Boston Diaries.”

Go figure.

An IDE for BASIC, on a machine with 128 bytes of RAM

If this sounds horribly limited and lame it's because you haven't yet thought about the hardware it's running on…

Via Reddit, HuguesJohnson.com - Atari 2600 BASIC Programming

Ah, the good old Atari 2600 Video Computer System. It could only address 4,096 bytes of ROM and 128 bytes (not megabytes, not kilobytes, but bytes) of RAM, 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 (or in other words, you are Racing the Beam).

It's not an easy machine to program.

So to even contemplate BASIC on the thing is insane. But it exists. 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!]

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?]

Still, I find it a fascinating system. Like Hughs Johnson 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™ is to be …

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site: http://boston.conman.org/, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

http://boston.conman.org/2000/08/01

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.
