The software was rewritten from scratch, and now runs on both Windows and Mac. In addition, a number of functions have been implemented on the pulse program compiler, array manager, acquisition setup, etc.
NMR data can be displayed simultaneously on as many separate plotters as you wish, with various viewing options.
The circuit boards of the previous version can be used as they are. For the FPGA part, you need to rewrite the core module of the latest version.
This is one of our Opencore NMR systems used for a 7 T superconducting magnet. The spectrometer hung on the wall has three rf channels.

I will try my best to add information there. I also plan to move the download site to github.

DOI:10.1016/B978-0-08-097072-1.00007-8OPENCORE NMR: Open-source core modules for implementing an integrated FPGA-based NMR spectrometer
In this work the name "Opencore NMR" was given, in the spirit of opening the developed FPGA core-moudules to public, so that anyone who are interested in the project can use them, together with board design, software, etc. In addition, a number of the conventional solid-state experiments were demonstrated, including 1H-13C-15N triple resonance, multiple-pulse decoupling, two-dimensional experiments, and so on.
