We have managed to lock-up our Aspect 3000 computer on our MSL spectrometer,
and we cannot unlock the **** thing. Here is how it occurred.
One of my students assigned
a value of zero to SI when running DISMSL. The system frooze. Re-booting
came up with the message
"invalid data set in job 1"
The screen does not display a spectrum, i.e not even a baseline, just blank,
but with the usual prompt at the bottom of the screen. Giving a command,
such as PPE gives the message
"job active"
The system is not cleared by CNTRL K or CNTRL E or CNTRL Q.
Other commands such as DIR, for example, are active.
EP gives a distorted display of a spectrum
I decided to re-load the software from the 4 program diskettes with
the instruction
"COPY **.*=F1/=D1:Y"
Then ran
EXE INSTALL
And finally
RUN DISMSL
The system booted to the same state, that is still with "JOB ACTIVE".
I had the idea that the problem might be in a corrupt SPC1 file, and so
I copied SPC2 into SPC1 and re-booted, but to no effect.
Previous experience of problems with the Aspect suggested that turning
eveything off and going for a long coffee break would help. This time
this did not help.
So, does anyone know how to kill whatever activity is going on in job 1?
