Hi Dave. In one of your reviews of the "Saleae" Logic analyser, you were using an old version of their Software,
(yours being Ver 1.1.15 I think), and were complaining about the limited number of 'Analyser' options.....
The LATEST version... (1.2.14), has a vast improvement there, including the 'JTAG' you would have liked.
OH!!! and it includes mouse dragging the channels up and down in the order you want !!! :-)
Here's a 'pic' of the selections now, for Logic Analyser options......
Also, when you have used 'LTspice', your version is (was) version 'IV' (4), but now there is version 'XVII' (17).
Have fun Dave. Both softwares freely downloadable....
