Ah, bummer - what about the 11/780?

Sampsa,

I'm pretty sure that the 3900 series machines only supported 64MB max
and that is what you are emulating.

I just increased the memory on one of my SIMH VAX VM's to 512 MB from
64 MB - the system boots fine but SHOW MEMORY (under OpenVMS 7.3-1)
still reports 64 MB.

Do I need to tell the VMS installation about the new RAM somehow? How
much RAM does 7.3-1 (VAX) support anyway?
