[Simh] VMS 1.5 installable?

[Wilm Boerhout]

Your approach is correct, I have regularly used it over the past weeks 
to bring up VMS 1.0.

I also saw these CRC errors on restore sometimes. There are two ways 
around this:

 1. Mount the 3.0 tape on a generic (newer) VAX/VMS system, use
    $MOUNT/OVER=ID and copy the LIBRARY and OPTIONAL savesets to a
    (RP06-sized) disk in the [0,0] directory. In a later step, $ mount
    /foreign this disk, and point the installer to this disk as the source.
 2. On your 3.0 system just booted with just the REQUIRED saveset, use a
    TS11 and not a TE16 tape unit in the simh config. Somehow this
    worked. Also, when you use a TE16, use an explicit $MOU/FOR
    /DEN=800. I forget in which version, but this also worked sometimes.
