In the quest to build a 68000-based protoboard computer running Linux, the author persevered through weeks of challenges, from hardware design to software coding. The hardware setup includes a Motorola 68008 CPU, SRAM, Flash ROM, and USB communication link. Building on existing 68K assembly language programs, the author delved into modifying the uClinux kernel to fit within 512K of ROM and RAM. Through multiple attempts and debugging efforts, a working system finally emerged, supporting multitasking and even running vi and Colossal Cave Adventure. The project raised questions about future iterations featuring video output, highlighting the balance between functionality and complexity. A downloadable source code is available for adventurous minds.
