AIM Software cassette titles (Atari 400/800)

Good afternoon folks,

I've recently come upon a lot that someone was looking to offload, consisting off various Colecovision/Intellivision/Atari/TRS-80 titles.  Many of them notably included the boxes and manuals, including a lot of Atari 8-bit titles.

Curiously however, the majority of 8-bit titles consist of Aim Software cassette titles.  There are approximately 13 in total, with boxes(fair condition) and instructions(if you can call them that).  The cassettes are in absolutely pristine condition.

I'm not familiar with the Atari 8-bit line at all, but it appears to me that it's extremely challenging finding any comprehensive information on the 8-bit titles anywhere.  So far I've only found Atarimania, and at least half of these aren't even recorded there.  Atarimania at least seems to indicate that AIM Software titles are especially rare, at least for the titles they have on record.


Are there any resident experts that can clue me in on what I might be dealing with here?

Thanks!
