I have a PDP 11/23 running unix 2.9.1, the system has one cpu, one RL02 disk drive and two RL01 disk drives. The unix os is on the RL02 drive. What I need to do is backup the os, any suggestions ???? I would also like to hook up a parallel printer, what hardware do I need ????? One other thing I would like to do is put this system on the net. I have a modem board and a modem but no news software, any ideas where I could get the software ??? Any help or suggestions would be nice ..... This is the fist DEC system I have come in contact with.

That is, it's off line most of the time. If so, get two RL01 disk packs, and do the following: Shutdown to single user mode. Put the first pack in the RL01. Issue the command: dd if=rrl0h of=rrlxh bs=5120 count=1000 (note. ^ Substitute the drive number of the RL01 here ^ .) When that's done, replace the RL01 pack with the second one and do: dd if=rrl0h of=rrlxh bs=5120 skip=1000 If you ever need to restore, then switch the little drive number buttons on the RL's, boot off the backup RL01, and reverse the dd commands. I hope this helps.
