Spellcaster

or, discovering and recovering a lost programming language over the course of a weekend

I go down rabbit holes. One of the great pleasures of this dumb future we live in is that you can dig through the milk crates of our culture forever, following whatever interests you, and there is no bottom. My latest rabbit hole looked something like this:

Wait, hold on a minute. This kind of sounds exactly like the weird idealized programming environment I keep in my head. Obviously with serious restrictions and caveats, but, as a learning tool? They implemented this on an Apple II in 1984? How far exactly did they go?

I mean, look at this:

So of course I went looking for disk images.

There were no disk images. There were a couple of scanned magazines with the same ad. That was all I could turn up.

I started asking around on the internet and a couple of people tracked down a few more references; a couple more short reviews in some magazines. The jackpot, though, was this reimplementation of Spellcaster written in Processing. The readme gave me names, and the names gave me email addresses.

Long story short, I reached out to Scott Gilkeson, the original programmer of the C64 version, and it turned out that he had conveniently made disk images a few years ago. He also put me in touch with John Fairfield, the original designer and programmer of the Apple II version, who gave his blessing to share them. (The Apple II version is lost, as far as anyone knows.) There was also a PC version, written in C; nobody seems to know where that is, either. Within a day of reaching out, I had a copy.

You can use Spellcaster now, right from your browser.

A manual is also available. (Scott is seeing about creating a higher-quality scan, but what's there is much better than nothing.)

John Fairfield would go on to cofound the company that produced the Rosetta Stone language learning software. Spellcaster is, in a deep way, also language learning software. There are some truly fascinating design decisions made, not only in the Spellcaster programming environment, as advertised, but also as a language.
