Heh!  Myself, I'm slowing a bit, just have too much 'broken stuff' that I
know I'll never live long enough to get around to, and even if I did, no
one would want that old 'obsolete' stuff.   :-((

The last dot matrix I fixed was one I was printing my daughter's school
papers on when it died on a Sunday night!  [25 years ago!].  I _had_ to get
it going, and found one section of a quad driver was dead.  I cut out the
dead section and replaced it with a TiP transistor, and it is still
running.  I've since collected a fair bunch of working ink jets, and they
are much easier to move around to wherever I need them.  Since I only print
about one page per month I don't keep any printers connected to the
computers.  

I actually changed from the dot matrix to the ink jets when I discovered my
20 year old supply of dot matrix ink had all jelled up in the bottles!  I
tried several solvents to get it flowing again, but not much luck.  Not
even WD-40 thinned it!

Hey, when WD-40 fails, it's time to quit!   :-))


     Good luck...  M.
