TTL future life after shock

[Radarmus]

Hi I have been missing around with a Deckel FP3a CNC there was dead in the controller.
We found some TTL there was physical open and when bringing the power supply to life on at testbench the problem was +5 volt was too high. After repaire of that board It seems to do something with the relay (CPU was running) but other board was also bad. A 74xx was exploded and who knows what number it had? The Ram was cracked open in the house, that could be replaced. We was taken the Eprom out for reading and the first show FD FD FD, The other was FF FF FF. We looked at the microscope and could see wire fused under the window. :-(. Now we gave up. But now i'm thinking if the eprom survive, how would the future be for a shocked TTL family, will they die for a while og be ok?

I'm sorry to say...might as well sell for parts as this machine is not highly favoured by machinists.

I don't think it's worth your time even to modfify it using modern cnc controls.Best to invest in a proper cnc.
