I've got a copy for my Vectors; boots, but I haven't gotten it to do anything; could be that the diskette doesn't have anything on it of course... Anybody know anything about this OS? Anything special that I need to do to get it to accept commands? One that I know about is DIAG, but that doesn't work either; just "Invalid command"s. m
