Recently I wrote an Application for iOS devices that can be used to load Apple 1 software through the cassette interface. One key benefit to this application is that is shows load and verify instructions for each program. I’m currently in the process of getting this added to the App Store.
Today I built up Mike Willegal‘s Apple Cassette Interface for the Apple 1. Previously I was using the Obtronix interface, however Mike’s board is a more accure reproduction.
After building my cassette interface and loading programs successfully from an iMac, I wanted to try loading programs from a cassette player. Thanks to Wendell Sander, we now know that the Steve’s used a Panasonic RQ-2102 cassette player. Luckily these exact players are still made today and I was able to get a new one very easily.
After finding the right cassette player, I wanted to create some authentic-looking tapes. A few tapes were included in a recent eBay auction so I have something to model after. I still have some work to do on the cassette labels, but here is what I have right now.
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.
