Apple ][ Disk Server

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.

ÏÃÔß±µß²°±¶

* Removed 8K option because new 9600 BPS code works on all machines and emulators. See: https://github.com/datajerk/c2t and https://github.com/datajerk/c2t/raw/master/article/article.pdf for details.
* Regenerated all audio files.
* Fixed nbsp formatting behavior.
* Updated Essentials titles.
