RSTS/E Sysgen Successful

Thanks to everyone who provided help of all kinds. I finished up the sysgen in just under two hours.. praying all the way that my semi-flaky Kennedy drive would behave during the process, which it did, bless it's little blower motor. :) I added support for RL02s, RK05s, RX02, PC05, and expanded some of the runtime language packages to include math and FPP functions. Everything else got the defaults. SO: the object of this sysgen was primarily to allow the use of the RL02 disks. And here I have a stuckness: I can sucessfully init an RL02 disk, erase it, exercise it, find it's bad blocks, and then mount it. All ok. But I can't allocate it, write a file to it, or get a directory. The error message is 'Device not available.' I can do 'show dev' and see that it is mounted, but from there I cannot find out what the next step is. I have a RSTS Orange Wall on the way in, but it will be almost two weeks before I get it. Until then.. what need I do to read and write the RL02s? NOTE>>> Especial thanks to Tim Shoppa and Bruce Lane! <<<NOTE None of this would have been possible without your kindness and generous sharing of Knowledge. Cheers John
