X704 410 MHz was a PowerPC-compatible microprocessor operating at 410 MHz introduced in February of 1997. This model was the final and only model actually produced by Exponential Technology in early 1997 with the plan of being implemented by Apple in their machines. The model was later dropped by Apple and faded into obscurity (See X704 § History).
