Welcome Apple II Fan to the Apple II Disk Server, where you can download over 1500 disk images directly to your Apple ][+ or //e disk ][ drive at 9600 BPS!!! Be sure to check out our sister site: Apple Game Server Online!.

Need help? Then please watch this video demo.

There are four download options: HIFI or 8KFI with FORMAT or NO-FORMAT. 8KFI is a bit slower (~15 seconds), but should work on all systems. If HIFI does not work for you, then it never will on that system, use 8KFI. Use NO-FORMAT if your disks are already formatted (it will save you about 30 seconds). For offline use right-click AIF or WAV and download.

Disk downloads take about 3 minutes and write to slot 6 disk 1. The most common cause of error is external sounds being piped into the download stream (e.g. mail alerts) and low volume--crank up the player and OS volume and try again.

It has been reported that interference from disk and power cables may corrupt the audio stream. Consider a high quality audio cable (e.g. Monster Cable has been confirmed to solve this problem).

It has been reported that the cassette jack connector can oxidize: 'The whole thing wasn't working for me until I put some "DeOx" on the audio cable tip and cleaned up the plug on the Apple II'.

* Restored 8K option. While the new 9600 BPS code works on all Apple II machines and emulators, it does not work with all computers transmitting the audio. Circa 2007 and 2008 (Mac and Windows) machines have been reported to fail with new 9600 BPS code.


* Removed 8K option because new 9600 BPS code works on all machines and emulators. See: and for details.
* Regenerated all audio files.
* Fixed nbsp formatting behavior.
* Updated Essentials titles.

* Added inertia scrolling, fixed iPad font rendering issues.


* v0.99 released.
* Some IE9 fixes. However, IE9 users will have to right click and download audio files since IE9 does not permit WAV or AIF in browser with HTML5 audio. Or, just use Chrome, Opera, or Firefox.


* Beta v6 released.
* Added friendly 'BEEP', "[RETURN] to reboot".


* Beta v5 released.
* Extra second of padding for slower drives.


* Beta v4 released.
* New 8KFI option that uses more reliable 8000 bps code. Try HIFI first, if that does not work use 8KFI. 8KFI works with emulators too.
* All audio files volume decreased from 100% to 75%.
* In-line help.


* Beta v3 released.
* New INSTA-DISK with less padding.
