This listing is for a vintage Borland Paradox Runtime 4.0 Database Software, complete with the Engine Install Disk. The set includes FOUR 5.25" floppy disks, still sealed in their original plastic packaging, suggesting they are new old stock (NOS). Paradox was a popular relational database management system, and this version appears to be for earlier operating systems, likely DOS. This is a rare find for collectors, enthusiasts, or those seeking original vintage software components. Please review all images for exact condition and included items. Since they are brand new in original sealed packaging, they are untested and sold as-is.
