While cleaning up the attic I found this package.
Which nicely proofs that we used to use FileMaker a long time ago. So somewhere 1996/1997 we bought Claris FileMaker Pro 3 and used it with a little database to track some inventory.
I do remember seeing the typical record navigation controls in several apps over the years and those may have been FileMaker runtimes.
When we started making FileMaker plugins in 2006, we got FileMaker Pro Advanced in version 8.5.
So how long ago are your roots to using FileMaker?
At FileMaker conferences I met people who started with FileMaker Pro 1.0 or even before with Nutshell.
And even if you needed to convert your database a few times, there could be solutions which run the last 30 years with FileMaker. That's a long time in computer history!
