I ran OpenVMS V7.2 on a MicroVAX II (KA630) back when I was in high school and it ran quite happily albeit very slowly with 16 MB RAM (and a SCSI disk). Just text mode but I was able to use layered products like TCP/IP or some of the compilers.
I've also run OpenVMS V7.2 on VAXstation 3100/30s _with_ DECwindows on GPX graphics ... again very slow but runs pretty happily with the full complement of 24 MB RAM in the machine. I no longer have any VAXstation 2000s but I'd expect they'd do almost as well as the KA630 ... being bounded by simply that, I don't think you can put as much memory in the VAXstation 2000, as in the MicroVAX II. I find OpenVMS runs very well just via netboot using MOP out of a VAXcluster ... I wouldn't even bother to try to install OpenVMS on the local MFM disk in a 2000; just go boot one out of your cluster and see how it feels - I think you'll find not as bad as you had originally thought! :O Best, Sean On Mon, Oct 5, 2015 at 3:12 AM, Pontus Pihlgren <pon...@update.uu.se> wrote: > On Sat, Oct 03, 2015 at 11:49:28PM -0400, Christian Gauger-Cosgrove wrote: > > So yes, [Open]VMS 7.3 will run on a VAX-11 series VAX.
