@kwatari, @ScottF idea with the (open) JDBC Paradox driver was a good one and I was able to access two older samples of Paradox databases.
First I would set up a new Database in the KNIME preferences with the driver from the Maven site using the full path, the type msaccess and the URL template:
jdbc:paradox://<file>
Then the DB Connector would have to be set up using the newly defined driver and the full path of the folder where the .DB files would sit (“Database URL”).
The start of the “Database URL” path will need a double // on a Mac system. I have not tried it on a Windows machine.
Then you will have to disable Transaction that is no blue checkbox with “Enable” (not sure if you really could and should edit or insert data in 30+ years old databases anyway). So this is read-only.
Then you would use the DB Query Reader to actually load the data into KNIME. The usual DB nodes seem to have a problem (no transactions) so you might just want to grab the data and do the rest in KNIME.
Finally success, we have recovered some HP printer settings data from a floppy disc from some 30+ years ago … KNIME takes this “we are a platform” thing to another level
