The forty or so aplets below were originally hosted on Hewlett Packard's
website. Unfortunately, the site was 'updated' in 2000 when it was given a new
look and they were removed. Most of them have now been placed
officially on HPs site again but they are also here in the interests of
completeness. Not
all of the original collection are here: some have been superceded by ones on my
other pages, while others... well I just didn't think they were worthwhile. But
most are here and well worth a careful look.
