Do you have any hardware documentation left on the Masscomps?
I have a 5700 here in the basement and a stack of floppies that
should be the install set for RTU 5.0, but the hard disk, a
Fujitsu Eagle, is dead. There is no information on the machine to
be found on the net at all and the newsgroup has been dead for years.
I'd put up a page on the machine myself if I knew something worth
telling about it. I don't have any hardware manuals, only a very 
incomplete set on the OS. 
Can I mount any SMD drive in the machine and tell the install about 
the geometry or do I also have to tell the controller? How do I
copy the disks? Can Teledisk duplicate them? (I once saw that it said it
copied the disk successfully, but the target machine couldn't read it.)
