Speaking of digital tube equipment, while I'm
not ready to get rid of this
stuff myself just yet, I'd like to ask whether others (the nearer the better)
might have any interest in tube-based digital frequency counters and such;
e.g:

No, they're not computers (unless one really wants to stretch the definition),
they are boat anchors and of limited to no practical use, but they are
manageable (barely) examples of vacuum-tube-based digital equipment.
Beautiful works of engineering art that look like they're new out of the box.
