Last night I installed the expansion card connector on my Apple 1, swapped out the capacitor on my cassette interface as recommended by Mike Willegal and fired up BASIC for the first time. Ultimately I intend to load programs using an iPod, but for now I am playing them from an iMac using AIFF files provided by W Sander. The cassette interfaces are very sensitive, especially to volume, but to my surprise I was able to load BASIC and Blackjack on my first try.
