Hp 1611A logic state analyzer with Z80 probe working
This trusty old beauty has been my trouble shooting workhorse for many years. It saddens me to sell it but I no longer troubleshoot hardware as much as I once did and this has been sitting idle for far too long. It's time to let her move on to someone who will use her more then I.
This logic analyzer has a probe which will attach to a live running Z80 and let you watch it execute with full code disassembly. You can set multiple watch points on addresses and registers and trigger a CPU wait or halt to examine what the CPU was executing right before (or after!) your trigger. This has been an invaluable tool for me in tracking down faults.
