Dec-Unix & Tru64

[couta]

Hi all,

a very newbie question.

What are the major differences between these 2 operating systems and some history,
ie:
- has/was Dec-Unix renamed to be Tru64 and when was this
- Is DEC-Unix still very active + who is supporting it ? - HP ?

apologies for the newbie question to these 2 OS's

Thanks

History:
OSF/1 (until version 2.0) -> DEC
DECunix (>= 3.0 and < 4.0F) -> DEC/Compaq
Tru64 (>= 4.0F <= 5.1B) Compaq/HP

- sorry, what is exactly "PVS" ?
- So by your comments, it means that DecUnix (which is up to Version 4.0F ) is no longer supported at all then. Just Tru64, Correct ?

Thanks

Hi,

pvs=prior version support
that means, that these versions do not have a regular support anymore and cost extra money to get support for.

greetings,

Michael
