This is the original install CD for the Umax S900 Series SuperMac clones, version 2.0 - It contains a full Macintosh System install of Mac OS 7.5.3L. Why is the system version 7.5.3L? Because this version is specially designed for Macintosh clones only.

Additional Software Included on the CD:

Inside the "Utilities" folder, you will find copies of "NetDoubler" from Asanté, "Conflict Catcher3" from Casady & Greene, and "TechTools Pro" from Micromat Computer Systems for your system diagnostic needs. You will also find FWB's "Hard Disk Toolkit Personal Edition" and "CD-ROM Toolkit"; utilities you will need to test and format system hard drives and mount CDs.

Also included is the complete manuals of the Supermac S900 User Guides, plus user guides for NetDoubler, TechTool Pro, Conflict Catcher, Turbo 128M, Hard Disk Toolkit and CD-ROM Toolkit (PDFs).

Caveat: Some of the supplied 3rd party software will run only on SuperMac hardware. e.g. TechTools Pro

Architecture: PPC

The included SSW 7.5.3 is perhaps the easiest system of this era I've had to install. Usually I've installed from those multiple parts for 7.5.3 from Apple - This was totally painless to install in comparison, using this CD. It's still good to run on SheepShaver.
However, this CD doesn't boot at all on Basilisk II, because it were based on Power Macintosh PCI system software.
