Just a `simple' box, perhaps even with PC hardware, so you can reuse VGA, PS2, ... emulation? The actual emulated hardware doesn't matter much for running e.g. Debian build daemons. Cfr. Linux/MIPS has a qemu target, just for running MIPS: | config QEMU | bool "Qemu" | help | Qemu is a software emulator which among other architectures also | can simulate a MIPS32 4Kc system.
