Need help: Eprom on Master Board A20B-0008-0200 for Fanuc 3T

I have an old CNC, TAKISAWA, Fanuc 3T control system. Master Board A20B-0008-0200
It is broken, no working, no picture, only the light on when I turn off
All volts : 5V, 24V,-15V, 15V are normal
A friend gave me 8 chips Eprom of other master board (My CNC use 10 chip HN462532). I plugged 8 chips into the sockets on master board and turn on. CRT have picture but I can not read the letters. I think my Eproms of master board are bad.
I need help from you on the forums. Someone, you have the source data ( Binary file) of these Eproms. Please help me. I would be thankfull.
