Someone is still making slide rules

For years, companies would give away at trade shows all sorts of
special purpose slide rules. Some were made of plastic, but
many were made of cardboard. When personal computers came
out, companies started giving out floppy disks with a computer program
in lieu of the old slide rules. We hated the computer programs.
The rules we could carry around to job sites and do quick checks.
At work, we guarded the old rules and I still have a few of the old
cardboard ones. They are still useful.
