Well this morning in the QL-Users list I had an email from Marcel Kilgus

"QPC2 v4 FULL version
To celebrate the birth of my daughter, here is finally the full release of QPC2 v4 for all to download and enjoy. It comes with a complete sample "hard disc" file that contains some sample applications and demos."

You can reach the site here http://www.kilgus.net/qpc/downloads.html 

QPC2 has always stated it is the next generation to the BBQL QDOS.

Great news at one level for everyone, sad news is that it means there is unlikely to be any further development of QPC2.
