Data General Eclipse

Hi all, I just managed to get hold of a Data General Eclipse MV9000. I think it has been upgraded since the processor card says MV9300. I has over a hundred serial ports, three hard drives (ZetaCo), 9 track tape drive, five D211 terminals and three printers. I'm looking for documentation and software of any kind for this machine but I have not found anything substantial searching the net yet. Any ideas? This machine was apparently the target of a search by the local HAM radio clubs for the source of a 125Mhz signal that was triggering the emergency signal receivers in Russian satellites. I'm trying to get more info on this little bit of history this week. The machine looks at home next to the PDP8/i. I'm running 240Vac to the machine this week so I'll get to see if it works. Any DG AOS/VS people out there? Mike
