The 68000 Dash 30fx, an Accelerated Mac IIfx

Most early Mac clones were built around 8-16 MHz 68000 CPUs or 16-40 MHz 68030 chips, but the 68000 Dash 30fx ran its 68030 at a blazing 50 MHz – 25% faster than the “wicked fast” Mac IIfx, which was the fastest computer on the market when it went on sale in March 1990.
