GuruModem Quickstart 3.5″ Disk for Classic MacOS


10 in stock (can be backordered)

SKU: quickstart-macos-1 Category:


3.5″ 800k floppy containing ZTerm 1.0.1 (compressed StuffIt 4.0 archive) and Stuffit Expander 4.0.2 Installer. Compatible with any 68k or PPC Macintosh system running System 6.0.5 through MacOS 9 with a Floppy Drive and a Hard Drive.

ZTerm and StuffIt Expander were too large to place on a non-SuperDrive floppy uncompressed, so you will need a hard drive in your Macintosh system in order use this quickstart disk.

Important Note about transferring files to/from your Macintosh

Macintosh stores files in a series of Data and Resource forks, and the resource forks specifically are problematic when moving files from a Macintosh system without using a disk or AppleShare. Without one or more of the these forks, files typically cannot be opened on a Macintosh system. Moving files to another computer (even if the other computer is a Macintosh) with a terminal emulator program over a serial link typically means encoding the files or using an archive tool to preserve these data and resource forks. MacBinary (.bin) files were a common way to do this, and ZTerm will automatically decode a MacBinary (.bin) file during download so that it is ready to use. BinHex (.hqx) is also a common way to encode files but generates much larger files because they are encoded in plain text for broadest possible compatibility. You can also add files and folders to an archive using a tool like StuffIt Deluxe (.sit), DropStuff (.sit), or MacZip (.zip) and safely transfer those files to other systems (the extraction tools look at the file contents instead of the resource forks to determine compatibility so they will open “generic” files). The StuffIt utilities were the most popular tools for creating archives for Macintosh systems pre MacOS X, which is why we have included StuffIt Expander 4.0.2 on this disk.

Why we included StuffIt Expander 4.0.2 instead of a later version

StuffIt Expander 4.0.2 works on System 6.0.5 through MacOS 9.2.2. Starting with MacOS 8 and later, StuffIt Expander was included in the OS install media as part of making it easier to use Macintosh systems connected to the Internet. So we included StuffIt Expander 4.0 for the broadest system compatibility, and because StuffIt Expander 5 and later would not fit on an 800k floppy (nor will it work with System 6). If your system is running MacOS 8 or later, you won’t even need to install StuffIt Expander as there should already be a version on your system capable of opening a StuffIt 4 archive. (Note: StuffIt Expander 4 cannot open archives created with StuffIt Expander 5 or later by default.)

Why we didn’t include StuffIt Deluxe or DropStuff

Partially for compatibility reasons, but mostly because we could not fit StuffIt with DropStuff plus the ZTerm utility on a single 800k floppy. Now that you have a way to extract a StuffIt archive, you can find the full version of StuffIt Deluxe or DropStuff at sites like or The Internet Archive for download.

Please note: the contents of the floppy are not being sold, just the physical disk and labor involved with creating and testing that disk. We provide an image of the disk for no cost. We are not charging for the contents of the disk, selling the software on the disk, or claiming ownership of the software on the disk. This product is being sold to help users who have no easy way of getting access to the tools included other than via physical media.
