We have multiple DOS-based programs that were custom designed for controlling and calibrating external electronic systems through a GPIB interface. These programs were written between 1985 and 2000 and are believed to be C/C++ based (Borland is listed specifically in at least one program). There is also quite a bit of script-like plaintext that exists in the executables. We believe that all of the GPIB-based communication is done using script-like commands issued from each of the executables.
The original source code for these programs is not available and the company that originally created them no longer support or update the software. We do have all rights to use and prepare derivative works from these programs, but we would like to have the same functionality reproduced in programs that we ourselves will own. We also wish to have this functionality improved by including more control structures that would allow streamlined usage as well as have these programs operate on Windows-based systems utilizing a USB to GPIB interface. Currently, one of these programs has been made to function fairly well using Windows XP and a USB to GPIB device.
Initially, we would like to have these programs analyzed to determine how feasible it is to recreate these programs with the above specifications. Once each program has been evaluated, we're interested in determining the cost to create the improved replacement program.
If this information is of any help, the programs generally range between 50kB and 140kB, with one program being 350kB.
Please bid only for the analysis phase of this project. We will not be deciding if we will go forward with any/all of the program conversions until we receive costs and time estimates, as well as await some external factors that may delay or cancel the development process. Thanks.
