I used to service a VAX 4000-200 that had one of those in, monitoring 17,000 endpoints in an oil refinery and crunching the numbers for a daily report to the site manager. If you don't have the peerway at the other end and the custom software it won't do anything.
That machine's probably still in its home behind the panels in the control room. I had to head over there every january to do a PM on it even after the chap who ran it left and they didn't replace him. One year I 'serviced' it (not much to do, it was clean and dust free) then went back the next year to find the Dead Sergeant prompt (>>>). Booting it back up I discovered it had crashed 3 days after my previous visit and nobody noticed. Not much point in going back after that!
