PDP11GUI is a great tool but it is extremely slow for dumping disks. It's not your setup. I restored an RL02 pack this way once (at 9600bps) and it took a very long time (I didn't time it but it was well over 6 hours). Compare this with restoring an RK05 pack on my PDP-8 using dumprest, which takes just about an hour... - Josh > > --FritzM. > >
