High schools were less likely to have access.
Even if they had, the average prospective Gaphing Calculator user wouldn’t be likely to have internet access there, wouldn’t have known the archives existed, and wouldn’t know how to use Kermit and BinHex to get the software on his Mac.
I was able to call into a free BBS run by the University of Georgia that ran a gopher server. Some way, I was able to telnet to Nyx and get a free shell account I could use to get to ftp freeware sites, but most people couldn't do that.

BBS's existed but were too slow, and expensive.
I've got a few CDs of later collections of the stuff. I remember buying clamshell-packaged games for $5 from Software, Etc (that turned out to be the first 1/3 of the game, for example). I remember seeing the magazines to order it from. I'm aware of shareware, and it's not related to what I was talking about.
