Yes, late December, 1987, after the events I describe. It was released on Usenet, as I recall. I didn't even know what Usenet was back then. For me, it was pretty exciting to dial up a BBS, crash their software, and read through the code that the BBS was written in (and later contact the sysop to tell them how to replicate it).
I doubt I could have even compiled the software onto a COCO 2 computer.
