Utility and Diagnostics Disks
Content by William R. Walsh, original here.
Provided for download here are several utilities and diagnostic programs for both EduQuest and 7386 computers. The table below gives both the download link and a brief description of what the disk does.
All of these files are in ARDI format (see this link) and will self-extract from Windows. While I have not tested it, the ARDI program will supposedly output a standard image file when a switch is passed to it from the command line. This capability might be useful if you don't have ready access to 720KB disks.
