S-100 Virtual Workbench: A Browser-Based Retro Computing Sandbox

The S-100 Virtual Workbench is a web-hosted project recreating the experience of working with S-100 bus computers, the modular hardware standard that defined hobbyist and early personal computing in the late 1970s. Hosted on GitHub Pages by user grantmestrength, the tool lets enthusiasts experiment with the architecture that powered machines like the Altair 8800 and IMSAI 8080 without needing physical hardware.

The minimal landing page suggests an interactive simulation environment aimed at retrocomputing hobbyists, educators, and anyone curious about the bus-based systems that predated unified motherboards. Projects like this preserve technical literacy around foundational computer architecture and lower the barrier for newcomers exploring computing history.

While the public-facing content is sparse, the effort fits a broader trend of browser-accessible emulators and virtual workbenches that keep legacy platforms approachable as original hardware becomes scarcer and more expensive.
