Write your reply.

assistant: Hi John,
Crumbs a CT!
gulp. It has got a hard disk in it hasnt it?
do you have the boot media? do you know the root password?
glug. Please describe the box. Colour of case. LEDs on the front enything
like that please. I think it might run CTIX but I could be wrong. It may be
older than I think.
Great.
What you have is a CT S80. Small box (smaller than a PC mini tower - well
thinner) probably in a colour often know to the rest of the world as brown.
Ive done an awful lot of work with these.
yep.
yep. console into port 0.
glug.
Someone has upgraded it. normally they were only 60Mb streamers - looks like
this one has a 150Mb. Just inside the opening where you put the tapes in it
might be printed.
fair do.
pull the drive out. Watch for the SCSI bus.
yep thats good.
^^^^^^^ this is the flavour of UNIX.
hmm. it can take a long time. However it might well be that the harddrive has
gone..do you have another m/c SCSI bus? If so check the disk will spin OK and
that you can do a raw read across the whole of the device without error.
Give this a try and let me know how it goes.
