Many other microprocessors, including the Intel 8086, 8088, 80286, 80386, 8080, 8085, Zilog Z80, and 6502 family, each have an input pin that serves a similar function to DTACK, but it is usually named READY or RDY. (On the Z80, it is named WAIT.) Therefore, a reference to DTACK distinctively implies the 68000 family of CPUs.
