Doom on the Vectrex: a port that preserves early hardware constraints
The Ultimate Vectrex Multicart 2, developed by Jason Kopp and Ralf Kornmann, enables the porting of Doom to the Vectrex, an ancient system with a 1.5MHz CPU and 1kb of RAM. The microcontroller in the UVM2 handles game logic and outputs to the old machine, allowing full functionality with sound from the cartridge’s audio jack. The system does not exceed the hardware’s limitations, as the port relies on existing components and avoids introducing new capabilities.
Graphics in the game include both hand-traced and auto-traced elements, reflecting the low-resolution pseudo-3D style of the original Doom. The port is playable using a .wad file from Steam or a personal copy, demonstrating compatibility with the system’s limits. No additional hardware is required beyond the UVM2 and the Vectrex itself.
This effort does not claim to redefine the experience but instead illustrates how the Vectrex’s architecture can be preserved through software adaptation. The project aligns with documented homebrew efforts, such as Scramble, and shows that certain systems maintain relevance through careful reconfiguration, rather than innovation beyond their design.
