I'm neither Villy nor Richard -- but here is what I'm using: the
pre-compiled Windows executable (MicroVAX 3900, extended memory
firmware, VMS v7.3 still without any patches) without network support,
currently SimH v3.7-0, not yet v3.7-2. The "host system" is Windows XP
SP2 with 1 GB of RAM.

System disk: 1 GB, user disk(s) 1.5 GB to stay below the 2 GB limit.

Custom size, built using the "mkdisk" utility of Software Resources
International primarily intended to create CHARON disks.

Yes.
