Hi there, my name is Didier Morandi, aka DTL. I'm a DEC OpenVMS Expert since 1981 when I read the whole documentation at Dassault Aircrafts to help them migrate from PDP-11/RSX11M to a brand new VAX-750 under VMS V3... Then, from 1983 to 1986, I used to work at the DEC France Telephone Support Center on VMS and Fortran mainly. On the 1st of June 1986, I started my own business as a Consultant (DTL Consulting) in Sophia Antipolis. Now, I focuse since 2003 on Alpha to Integrity migrations (read this doc from HP).




Some History


The picture above is The Cotton Mill building in Maynard, Massachusetts, USA, where Ken Olsen (1926-2011) created Digital Equipment Corporation in 1957. On the 1st of January 1998, Compaq (sadly) acquired DEC, then in 2002 HP (hopefully) acquired Compaq. OpenVMS survived thanks to its Customers base and its exceptional quality and safety. In 2013, HP (today HPE) announced they will "exit the OpenVMS business by 2020". In 2014, a few former DECcies created the VMS Software Inc. Company (VSI, picture up right) to take over the OpenVMS life and future. The 31st of July same year, VSI has entered into a license agreement with HPE to develop and release future versions of OpenVMS. HPE ended OpenVMS sales and support on the 30th of June 2019. Good bye HPE, Welcome VSI and its catalog.
