➀ Tech enthusiast Cameron Kaiser successfully ported the iconic game DOOM to a 1996 Apple Network Server (ANS) running IBM's AIX OS through custom compilation and adjustments.
➁ The ANS, priced between $11k-$19k in the 90s with 64MB RAM and 2GB storage, required overcoming 8-bit color limitations and video hardware quirks to achieve playable performance.
➂ This retro hardware hack demonstrates the extreme adaptability of DOOM's codebase, with the project now open-sourced on GitHub for other vintage computing enthusiasts.
