Disc analyser news update

Thank you for the response. Over the years, I can't remember using a logic analyser more than two or perhaps three times. Since I usually work on projects by myself, I would not have had access to one. The last time, the fellow in charge of the project was not able to program, was was a whizz at electronics and could connect the logic analyser faster than I could see what he was doing. In addition, over 90% of my work for the past 20 years has been on the PDP-11 which has mostly adequate tools to debug the code, especially now with the Ersatz-11 emulator which adds a very low level of breakpoints which are able to operate even to debug the very first instruction during a boot far in advance of any debug program being set up. Of course, the hardware ODT debug could often help there as well, but not as conveniently. As for your last point, your observation that when instructions and data reside in cache, a logic analyser is not going to be very useful is an aspect I had not ever thought about as a potential problem.
