Where can I obtain the manual for the card and software?
Two versions of the manual can be downloaded in Adobe Acrobat PDF format from the support area on Apple’s web site but the location seems to change periodically. Try performing a search for “IIe card” in the manuals section. For use with version 2.2.1 of the software, you require the manual called “0301930AppleIIeCrd2.1.pdf”.
