As a published RPG product, it predates the other things for which I'm known (including the d30 DM Companion, the otherwise first of my published products). It has been available as a free PDF download (direct from this link) and in print-on-demand from Lulu.com.
If you've never heard of The System, here's the topline overview... I originally wrote/designed this in late 1985/early 1986 (when I was about 16 years old) before other universal role playing systems were available on the market. As I was getting ready to playtest it with my friends, a guy in our gaming group brought in a copy of the (then) newly-released GURPS, and I shelved my system in the disappointment that comes with having someone beat you to the punch. In 2011, I "rescued the from oblivion" (that is, I scanned the old daisy-wheel printed version that came from my dad's word processor at work), gave it a (very) quick polish to the ruleset, and typeset it with a decidedly retro (1st generation) RPG feel to it.
As stated previously, I'm quite willing to admit the game has its flaws... I mean, c'mon, I was 16 or so when I wrote it. (e.g., there is a very convoluted constitution-to-hit-point system, and there is an innovative but ultimately ill-conceived initiative and movement tracking system, and while it purports to handle supers among its genres, I can't claim that it actually scales to reflect the expanse of power levels between the weakest and strongest heroes). But over time, I have more and more appreciation for the fact that it uses d6s only, and led to some underlying things that Welbo and I would like to see become part of a "2nd Edition" of The System. (Should we ever get back to it, but may something it takes us 10 or more years to complete.)
