Hobbyist builds Motorola 68K computer with PCI bus
A homebrew 68K machine adds a PCI interface via FPGA, enabling modern add-on cards on retro hardware.
What to know
- A hobbyist built a working Motorola 68K computer on protoboard with a functional PCI bus—atypical for non-x86 machines.
- The PCI interface was implemented using a Xilinx Spartan II FPGA as a bridge, enabling use of modern expansion cards.
- The machine runs a 10 MHz 68000 CPU with 1 MB SRAM and demonstrates detailed documentation of the engineering approach.
“At the heart of the build lies a Motorola 68000 running at 10 MHz. It's got 1 MB of SRAM, 4 KB of ROM, and a MC68681P acting as a UART, timer source, and I/O controller.”
