Someone gave me 2 of these machines that he had in his attic since about 2001. they came from a local school district and has all the school programs on them.

Well, i fired one of them up, and the machine ran, however the HV was arcing every once in awhile with a jerk in the picture each time. it eventually stopped, but are these flybacks known for failure? dont think ive seen any of them arc like this.
