There’s FreeDOS and classic games like Doom ready to play around with, or you can use your own disk images.

The live demo you can boot with a single click is impressive, with tabs to interact with and configure your browser-based, dependency-free Intel 80486DX2-66 PC in a browser. The first tab is dubbed the CRT monitor , and this is where you will spend the most time using the command line, apps, and games. However, it is also very appealing to be able to adjust your PC configuration in the tabs for Motherboard & Slots, Storage Bay, Custom Card Studio, and System & Diagnostics.

I couldn’t resist taking the e486-web for a spin using the live demo. The CRT monitor screen is totally charming, with various display options including color and scanlines, and tributes to classic CRTs with green phosphor, amber, or paperwhite displays. This is the screen where you will also type DOS commands and interact with whatever you get to run.

The next tab in this comprehensive 486 PC system emulator lets you pick a motherboard design and, probably more importantly, add and remove expansion cards. The default system comes with a VLB graphics card, Sound Blaster 16 ISA card, a multi-I/O controller, network card, and more. All the cards seem to be configurable. A Custom Card Studio tab lets you create and test more cards, and it looks quite advanced.

I spent quite a lot of time in the Storage Bay tab, switching through the OS and software disks inside the “1-Click bundled & Cached Disks” collection. FreeDOS started fine, but I got some errors when I wanted to test some of the games in the library, which includes Doom, Wolfenstein 3D , and more. Though tempted to find and install Syndicate on the hard disk that the emulator can create and configure, I didn't get around to it yet. However, the Bullfrog classic is one of the first games I played on an actual 486DX2 system in the 1990s, and I also played it on Amiga. This browser-based emulator features browser persistence, so e486-web settings can be maintained between sessions, and it automatically caches ROMs, floppy images , and custom uploaded .img/.iso files for your convenience.
