For My Next Trick
I’m going to try the logic analyzer on the Z80. I’ll just monitor control and a few address lines and count on knowing the program contents – probably all 0’s to start.
Looking at the timing diagrams it looks like i can usefully monitor as few as /mreq /rd and /m1 for starters – the address bits will be valid on the leading/falling edge of /rd. Oh, I’ll also need /reset. So I’ll have a grand total of 4 address lines to play with.
