Hi Patrice,
I would keep it if I were on your place. Of course, some people might say, that this monitor has no value. But do you know how many of this monitors still exist? If it has a good crt, and if you can bring it easily to working condition, it is worth to keep it. I am the owner of a monitor from 1970. It has no value. But the technique is unique:

These old relicts have no other advocate than us. If we don't take it's part, no one else will do it.
Kind regards,
