Repair of a Fidelity Elite A/S Challenger

I wish to take up chess again and have a Fidelity Elite A/S Challenger, having not been used for many years it is dead.  I am a technical person and believe the eprom has corrupted after 35 years.  Capacitors and power appears ok.  Has anyone, or knows where I can get a circuit diagram and or a memory dump of the eprom.

Thank you

Do you want to play chess or fool with old computers?

Forget the Fidelity. Play here. 

My grandson has started to take interest in chess which is great.  I have started to play with him and wish to also revive the old Fidelity which also interests him. In looking for information about the Fidelity I came across Chess.com.  I need to get back up to speed to be able to be a contender to play here. 

I had a Fidelity Chess Challenger, not the Auto Sensory version.  It was fun.   It may still be in a box in my basement.

Computers today are no more soulless than the ones then and the ones today play much better/faster than the old ones did. You can do a lot more training on the new ones. 

The poster said he wanted to take up chess again, not electronics salvage.  

If the goal is to actually start playing chess again, there are a lot of resources here that will have him in better playing shape than he ever was back in the 80's.

You'll probably have better luck getting advice on either the HIARCS forum or the Talkchess forum. Some hard-core collectors hang out there:

Usually it's the reed switches that go - why do you think it's the eprom?

No numeric display no leds lit just a click on the sound when powered up.  Caps seem ok, volts everywhere, it cannot boot and eproms have a limited life, 

Thank you, I hate the the throw away society today and have always repaired items and restored them.  I want my grandson to grow up with this understanding.

Thank you "Notmtwain",  I'm sure the new models are faster, but my grandson is 8 years and to my delight has taken up chess.  I have not played chess properly for 30 + years so he can learn and I can regain my play.  I hate the throw away society that everything has to be replaced.  Older items can work just as well as a new items and are easier to modify-update because of the components used.  This is impossible with a lot of modern equipment.  So I hope by restoring this Challenger he will learn both Chess and that not everything needs to be new or replaced.  Later we can join everyone on chess,com when we both become more proficient.

Thanks again for your replies
