Tiny68K, 68000 SBC

Tiny68K is a high-performance yet low-cost single board computer based on the Motorola 68000. Tiny68K has two unusual features:

The entire 16-megabyte memory space of 68000 (except the top 32Kbyte of I/O space) is filled with RAM,

The boot software residesin a 32Kbyte serial flash that is copied into the lowest 32Kbyte of the DRAM when powered up or with a reset. The RAM-resident boot software can be modified just like any data in RAM but is overwritten on the next power cycle or with a reset.
