Paradox 1.x

Originally released in 1985 by Ansa Software and later sold to Borland, Paradox is a high-speed relational database product that integrates with Borland's "Turbo" products. It was notable for its Query By Example feature, and its Paradox Application Language. It was popular in the late 80s and early 90s, and competed against database product such as dBase, Symantec Q&A, Foxpro, Clipper, Clarion, DataEase, R:Base, and DataFlex.

Wanted: 1.1 for DOS, manual scans.


Installation instructions

Paradox 1.0 is protected with the SoftGuard copy protection system, similar to MusicPrinter Plus 1.1. No unprotect is known to exist.

This copy protection is very, very, very problematic in that it is both speed sensitive, failing on some faster CPUs, and that even kryoflux written copies seem to fail the protection check depending on the specific drives used to write and read the disks. I was able to run copies on several XT class machines, but it failed on a 286-12.

It seems as if both System Disk 1 copies have been used for a hard drive install. Each disk could only be used once, and doing so writes data to the disk. Both look like they have been modified.

PSI images are provided for use with the PCE emulator. PCE is known to run the program with its copy protection.
