You are very welcome! In the meantime you can press Control + Reset to enter BASIC which would allow you to write & run software in BASIC. BASIC does not have access to the disk drive. It is meant as a lightweight way to use the Apple. BASIC can however access the cassette interface for saving and loading software to a cassette tape.

If you have any questions regarding the Apple II then feel free to reach back out to us! I personally find great joy in using an Apple II. I still have my childhood Apple //e and lately I have completely upgraded it with a solid state disk, mouse, internet, 16-bit sound, more RAM, faster CPU, etc.. There is a project currently in development that took Apple’s ProDOS operating system source code for the Apple II and they are releasing updates which bring new features to the Apple II. With a proper RAM upgrade your Apple II+ would be able to run the more modern ProDOS operating system.

It is strange that the video on their website is not working however there are quite a few videos on YouTube that should show you how to get up and running. There are two ways to bootstrap, using serial or using audio (which connects to the cassette interface). Serial is much more stable however it would require you to have a Super Serial Card and a USB to Serial interface for your computer. Audio bootstrapping is more widely accessible however it can be unstable.

few questions. I have two drives and with the card in slot 6 both will have their red led go on when in the top pins on the card though I don't hear the usual clicking of the drive turning. I am concluding that I either have broken drives or a broken card.


is that an accurate conclusion?


I have a macbook pro running mojave so I need a USBC to what? in order to connect it to the apple 2 plus?


thank you for your time during this late covid conversation

Most likely the drive’s rubber belt (inside the disk drive motor) has degraded. Rubber can often disintegrate after nearly 40 years. Slot 6 is the appropriate slot for the Disk ][ card. If the Disk ][ card was not functioning you would not see any power indicators on the disk drives. Something else that can occur is a solder point on the Disk ][‘s controller board can break. This would require you to dissemble each drive and use a voltmeter to check the continuity of each trace. I’d be willing to bed that your drive’s belts have disintegrated.


Here is your wiring setup:


MacBook Pro <-> USB-C to USB-A Adapter <-> USB to Serial Adapter (see Amazon listing below) <-> DB9 to DB25 Adapter <-> DB26 to Super Serial Card on Apple II

You would need to also have the Super Serial Card inserted in Slot 2.
