Greg Tinkler
Start in a partnership in 1980 building theatre and gaming related machines and software.Started working for Road Traffic Authority Victoria, on RSX in 1981, and VAX/VMS 1983 with a 2 x VAX-11/750 and HSC50 cluster, yes that was before the VMS supported clusters but they worked around that. This included a large amount of software development including converting from Rapport DB to VAX/Rdb, and using ACMS/TDMS for user interface.Joined Digital in 1987 a a system manager, after a year was moved promoted to a principle consultant (Information Management).

Joachim Wlodarz
He has a quantum chemist/physicist by background, active in academia since the early 1980s. There was always a need to squeeze as much computing power as possible from the available hardware, so over time he also became a computer scientist/specialist.He currently serves as a university professor at the Faculty of Science and Technology of the University of Silesia in Katowice, where he teaches mainly computer science-related topics. This also gives him the opportunity to spread the word about OpenVMS to students, which is why he is here.He has also managed to save quite a bit of hardware from the scrapyard, so he is also involved in preserving the past of computers for the future.
