How to find the model name of machine you're logging in?

[g hugh song]

Hi,
Is there a command which shows the model name of a Unix computer you are 
remote-logging in?
In our site, there are a bunch of DecStations in the network all tied together
by NFS.  The command name which finds the architecture in Ultrix
is "machine".   Then it shows either "vax" or "mips".   But I would like to
know whether it is DS 5000/200 or DS 3100 or DS2100 or Vax 6000 or Vax 9000
?
Is there a special file in the directory tree which tells the model name?

Thanks in advance.
