Even thought the HP3000 reached 'end of life' in 2006, HP3000's continue to run all over the world, thanks to companies like Newcorp. GUI Innovations was originally formed to support the HP3000, and to build GUI3000. GUI3000 continues to be supported and maintained, but is no longer under active development. More information on GUI3000 can be found here.
We also have SQLLink3000 which allows you to access SQL Databases directly from your HP3000. Any database that supports an ODBC connection should be available directly from your HP3000. We also provide a SDK for programmatic access from Cobol or 4GL's. More details can be found here.
