Is anyone familar with these? I don't don't know much about them other than that the surplus dealers all think they're worth a fortune. Anyway I "rescued" one out of a scrap pile. First, is it worth trying to repair and use? I already have a Data I/O model 29. Second, it's missing the two disk drives but otherwise it seems to be in decent condition. Can these use standard 3.5" floppy drives? I THINK these have their complete operating system on disk. Can anyone confirm that? Does anyone have the SW or manuals for it? Joe
