YouTuber Throaty Mumbo successfully ran Windows 98 on a smart toaster by disassembling the Revolution Cooking High-Speed Smart Toaster and using a Raspberry Pi 5 to emulate a late-1990s Pentium II PC. He created a custom program called “toast.exe” to facilitate communication between the Windows 98 interface and the toaster's hardware. The project resulted in a functional system that allows users to operate the toaster through a retro Windows 98 environment, complete with a 7-inch HDMI monitor and a 3D-printed shell designed to resemble a classic PC.
