You can store multiple versions of Newport and records in different directories (its small enough to replicate that way without eating much disk space).
I run Newport under DosBox (using a Slackware based Puppy Linux) with a cut down version of Win 3.1 so Newport is running under its original target architecture and multiple versions of DosBox (and hence Newport) can be run at the same time.
You can even open the same record set and for instance edit notes in one and then save, and open notes in the other and see the new edits.
Haven't tried under WINE (Windows emulator) but suspect its the same.
