I'm a complete packrat, and a sucker for anything
that looks remotely
"interesting"... as my long-suffering mother will gladly confirm :)
I spend far too much time and money looking at second-hand books. I tend
to buy just aobut an 'old' book on electrical/electronic subjects (I
think the oldest I have is datad 1892...), and anything that looks
'interesting'. A book containg a scehamtic or ROM listing for a
commercial product is almost certain to end up on my bookshelf.
