We are having problems powering on one of our NeXT workstations.  To give you a
little background, this is what lead up to the problem:

One of the users powered the machine on and then put a diskette in the the disk
drive. (Basically I think they hit the power button and then immediately put thedisk in the drive).  I guess the machine did not boot up correctly and they 
couldn't get the diskette out of the machine or power the machine off.  To get
the diskette out they used a paper clip, only instead of putting the paper clip in the little hole next to the disk drive they tried to put it in the disk      drive (along with the diskette).  To make a long story short, they got the
diskette out.  Now sometimes when the machine is powered on it boots up okay,
other times it does not and will eventually if you keep rebooting it.

Today I managed to log the following error message:

If anyone can offer any help I would appreciate or is this machine fried?

Thanks in advance
