We have games probably written in Delphi but only executables for Windows XP. These games were sold with the information that their software was prepared to accept signals from payment devices (PD), specifically coin validators (CV) and note validators (NV).
We are using Innovative Technologies's NV8 or NV10 note validators, and whBerlin's EMP850 coin validators. Both these NV and CV work by sending logical inputs into the PC corresponding to whatever amount was entered through the NV or CV.
The seller of the software seems to be unavailable to support us in our requirement to establish a connection between the PD and the software. Last information received was that we would need to use BDE (Borland Development Engine), and that the games would accept the signals from the PD either through the COM1 port or through pin 11 of the parallel port of the PC. And this is about all we know.
We wish to post a challenge to anyone who could eventually solve the development of a software solution that could interface the NV and CV with the games software we have available (MS DOS batch files). In other words, we need the games software to recognize the signals sent by the PD, which correspond to credits for the games.
We meant BDE - Borland Database Engine
