I would not expect problems there, provided you install V7.3 on the 
11/780. See below

/Wilm

$ sh sys/noproc
OpenVMS V7.3  on node VX0001  24-OCT-2009 15:37:06.61  Uptime  0 00:05:48

$ sho lic /cha
VMS/LMF Charge Information for node VX0001
This is a VAX-11/780, hardware model type 1
Type: A, Units Required: 13     (VAX/VMS Capacity or OpenVMS Unlimited 
or Base)
Type: B, * Not Permitted *      (VAX/VMS F&A Server)
Type: C, * Not Permitted *      (VAX/VMS Concurrent User)

This is essentially the same system disk that the MicroVAX 3900/ 
VAXserver 3900 boots from, AUTOGENned for use with less memory.

Dig this:

$ sho cpu
