PDP-11/23 deskside machine -DAMN

After putting the skins back on the machine it is giving me a ERROR 13 - DU0 not ready error. DAMN! I knew it wouldn't be that easy. I have a couple of spare ST506-type drives to hang off it but don't know how picky the controller is or where to find install media for an operating system. The drive sounds fine (spins up and purges but no boot anymore) DAMN. What free operating systems are out there for this machine. I suppose I will get another drive up and running and then get the data off of this one if it is possible. DAMN. To be honest I think I didn't park the drive before powering off the last time and suspect a head crash wiped the boot sector or something like that. Now when I try to boot I hear the drive track but get this error. DAMN. How can I get boots to restore a system? Yes, I suspect it ran up to six terminals as there are two controlled from the cpu card and four controlled by a terminal controller card. 512KB MEMORY KDF11B-BE ROM V0.9 CLOCK ENABLED BOOT MENU Device Physical Valid Unit Name Device Numbers DU DSA 0 1 2 3 4 5 6 7 DL RL01/RL02 0 1 2 3 DX RX01 0 1 DY RX02 0 1 DD TU58 0 1 XH QNA 0 1 MS TQK25/TS05 0 TRYING UNIT DU0 ERROR UNIT DU0 ERR 13 DRIVE NOT READY WISH TO REBOOT [Y,(N)]? -- ----------------------------------------------------------- Jeffrey S.
