This article is from the Apple II Csa2 FAQ, by Jeff Hurlburt with numerous contributions by others.
How: By far, the easiest and quickest way is to access software sites on the net using a PC or Mac. Files can be moved to and from your Apple II via a NULL-modem connection with the net computer. If you use a Mac, you may have the option of transferring the files via a ProDOS or HFS diskette or an HFS Zip disk. (For details on hardware, file transfes, downloading, and uploading, see the Telecom-1 and Telecom-2 Q&A.) Where: Today, most users upload software, info files, etc. to one or more of the major Apple II ftp software archive sites. Other options include comp.binaries.apple2 and BBS systems. The software archive sites are good places from which to download software. In addition, some software vendors, developers, and Apple Computer make software available for download at their sites. --Rubywand
