Infinite Mac Adds Browser-Based BeOS Emulation

BeOS Now Available on Infinite Mac

Infinite Mac, a platform for experiencing historical Macintosh operating systems in a web browser, has expanded its offerings to include various versions of BeOS. This integration allows users to run BeOS directly within their browser, providing access to a multimedia-focused, multi-tasking, and multi-threaded operating system that was once a contender for Apple's next-generation OS in the mid-1990s.

Emulation Features and User Experience

The BeOS installations on Infinite Mac function as full peers to the existing Mac emulations. Users can boot BeOS instantly, with large disk images streamed as needed. Each instance comes with pre-installed software from Infinite HD, supports virtual CD-ROMs from the Internet Archive, and allows users to save their work on a dedicated "Saved HD" drive. This setup provides a comprehensive experience of the BeOS environment.

Technical Challenges and Solutions

Integrating BeOS required addressing several specific emulation challenges. These included resolving a bug in ADB emulation that caused the BeOS boot loader to incorrectly detect modifier keys, fixing display corruption issues related to screen depth changes due to differing notification orders between Mac OS and BeOS, and adding support for little-endian video memory updates used by earlier BeOS versions. The project leveraged the DingusPPC emulator, which had made progress in running BeOS.

Historical Context of BeOS

BeOS was developed by Be Inc. and was notable for its advanced multimedia capabilities and efficient multitasking. It was ported to Power Macintosh systems in the mid-90s and garnered significant attention within the Mac community. Apple considered acquiring Be Inc. as part of its search for a new operating system, a path it ultimately did not take, opting instead for NeXTSTEP. The availability of BeOS on Infinite Mac offers a look at this alternative historical trajectory.
