Straker, some of the things you are saying, are a trip down memory lane !
But I must address this one quote of yours :

I agree mostly with what you had to say. Except that the Eagle Spectrum does have a 'Recovery Speed' adjustment of 1-40,with '20' being preset. ..
A) For starters, as you know, there were several in the evolution of incarnations of this spectrum to xlt series, right ? Wherein the box shrunk, changed colors and names, etc.... Yet all on the same similar menus, control names, etc... Right ? And yes, they had the adjustable recovery speed control, just as you say. I used to always set mine at 27
But that is not the "lag" or "delay" I am talking about.
You're right, that would speed up the time of the AUDIO . Which is instantaneous with the swipe of the coil over-said-objects. But...
B) The "lag" I'm talking about is the VISUAL. Despite immediate audio, there is a micro-second delay from the time you've swept over the target, to the time the machine flickers the # (or graph or whatever option you've chosen)
for your screen.
If you only ever started with the spectrum or XLT, then you might not ever have noticed it. Because it would have been what you grew up with, so-to-speak. But if you had started with the Eagle SL II, THEN you would notice it. The sweep & TID was more instantaneous.
I used the original spectrum and the XLT. This was my observation, from having come from the earlier Eagle SL II days.
