Re: Walnut Creek CD-ROM
Also early FreeBSD, Slackware[0], the simtel collection, Project Gutenberg, X11R5 (and later R6), perl, the complete monstrosity known as ADA ... later, that new-fangled Apache & accessories for people fiddling about with the WorldWideWait thingie ... All available either on very inexpensive CDROM or a download via FTP to your shell account, then to your home computer over dial-up (quite spendy back when even local telephone calls cost money per minute ... was usually far cheaper to have the CD mailed to you, unless you lived near Walnut Creek. Or had a Fry's Electronics nearby, they carried most titles.).
[0] When Slackware 1.0 first came out, Volkerding was quite surprised to see his FTP server crash under the load. And then crash again. And again ... Walnutcreek CDROM volunteered server space and bandwidth on ftp.cdrom.com ... The rest, as they say, is history.
