The software was released on a number of bulletin board sites that were available at the time. (BBS). These are no longer available today, but some of their indexes have been recorded and even the software preseverd.
The dates for the uploads are typically preserved in the file listings, and based on an internet search as of 7/2010, I found some examples which I've preserved below
When I uploaded a new version of Aporia, I typically removed or overwrote earlier versions with the newer ones so that users would not get confused. This has made it difficult to show when the first releases occured, since many of the BBS's have the last or near last version of Aporia (1.4b or 1.4c). The .03 or .04 releases, which were the first public releases are harder to find now.
