I also collect bookshelfs, to hold the documentation
for items in my
computer collection.
These are not essential. I just pile up the manuals on the floor. In a
couple of places I'e got piles that go floor-to-ceiling!
I also collect older electronic test equipment, so I
can work on systems in
my computer collection.
And so you can fix other items of test equipment :-). You need _2_
'scopes so you can use one to fix the other when it malfunctions...
