A few years ago I updated my web store system, but left the old store up as it was still getting hits.
I did put a "see our new store at..." flag on it. I have finally taken the old store down.
So, if you have some old links that have oscrc4 in them, they won't work anymore.
Just go to pico-systems.com and you can pretty quickly navigate to any of our
products or documentation.

Sorry for the inconvenience, but the payment card industry was pushing me to
update, and the new server should bring up pages faster, too.
