Apple Power Macintosh 7200/90 M3979 24MB RAM 4MB VRAM Tested No HDD

Description

Up for sale is a vintage Apple Power Macintosh 7200/90 desktop computer, tested and working. This is a nice mid-1990s PowerPC Macintosh system that was tested using an external BlueSCSI device and successfully booted into System Software 7.5.5.

Important note: This computer does not include an internal hard drive. The external BlueSCSI device used for testing is not included. I can included and build out an internal BlueSCSI for an additional cost.  Just ask :-) 

This system includes an AppleDesign Keyboard and Apple Desktop Bus Mouse II. The computer powers on, displays video, boots successfully from the external BlueSCSI test setup, and works with the included keyboard and mouse.

A key upgrade/detail on this machine is that the video RAM is maxed out at 4MB total VRAM — 1MB onboard plus three installed 1MB VRAM modules. The VRAM slots are fully populated, which is the maximum onboard video memory configuration for this model.

Great machine for a vintage Apple collection, System 7 software use, classic Mac gaming, file transfer work, or restoration/display.

Testing Performed

This computer has been tested and confirmed working as follows:

The external BlueSCSI device used for testing is not included, and there is no internal hard drive included. I have not tested every port, expansion slot, every installed application, CD-ROM reading, floppy reading/writing, or every possible function.

Software / Drive Contents

The computer was tested using an external BlueSCSI device booting System Software 7.5.5. That external BlueSCSI device is not included, so no installed hard drive or drive contents are included with this sale.

Cosmetic Condition

Good vintage condition overall with normal age-related wear, scuffs, marks, and discoloration/yellowing typical of 1990s Apple plastics. Front plastics and case panels are present. Internal plastics/drive rails are shown in the photos.

The AppleDesign Keyboard has one missing function key as noted above. Please review all photos carefully for exact cosmetic condition.
