Re: Z80 /WAIT signal question

I do know that the Wait signal was used by the Fluke 90 tester so it could be clamped on top of an in circuit Z80 and run memory and I/O tests while the CPU was doing its regular operations. On vacation so haven't easy access to the operators manual for the Fluke 90 though... John :-#)# > On

Z80 /WAIT signal question

A friend building a Z80 system asked me about whether the Z80 /WAIT signal has any effect during machine cycles that aren't memory/IO/intack cycles (i.e., neither /MREQ and /IORQ asserted). The user manual only describes the use of /WAIT for adding wait states, so I expect it probably only affects
