Apple Assembly Line

Apple Assembly Line Archive

A while back, I downloaded all of the issues of Apple Assembly Line that had been archived in GEnie’s A2Pro file area. Up to about the mid-’90s or so, GEnie was home to one of the largest and most vibrant Apple II communities out there. The rise of the Internet killed off GEnie (and most of its competition…when was the last time you logged into CompuServe or Delphi?), but my packrat instinct suggested that I ought to save a copy of these for myself.

I have every issue that GEnie had in its collection at the time. The only change from the way they were presented on GEnie is that I renamed the files so that a directory listing of them could easily be sorted chronologically… instead of “AAL.JAN.85.BXY,” for instance, that file is now “AAL.8501.BXY.” The info about each issue given in this HTML document is, if I remember right, the description that GEnie had used for the file.

So, without further ado, here’s the archive. The whole lot is only about 2.5MB, so you can either just click away at the links or use your favorite download manager to “leech” all of ‘em in one swell foop. :-)

The entire collection is also available as a single ZIP archive. It’s mainly of benefit to non-Apple II users who might want to browse the collection. (There are unzip programs for the II, but ShrinkIt files are better if you’re working with this stuff on a II.)

Also, I received email on 2 Nov 99 from Bob Sander-Cederlof, the publisher of Apple Assembly Line. It turns out that publication ceased sometime in 1988, which means I’m missing a few files. If you have ‘em and can send ‘em to me, I’d be interested… send me mail.
