When this repairs section of the website is finished it should contain tips on maintaining chess computers in good condition; general advice on repairs and renovation, on power supplies, chess pieces etc; and illustrated descriptions of repair projects carried out by myself and others. The idea is to build up a store of knowledge over time which will be of use to anyone in the chess computer community.
I am no electronics expert, and only carry out the sort of simple repairs you see in these pages. My own experience is that over half of chess computer faults consist of broken or corroded reed switches, faulty LEDs or control buttons, loose wires and badly soldered joints, loose or split ribbon cables and similar problems which can often be repaired with limited knowledge and experience.
Our throwaway age does not encourage the repair and renovation of old equipment, but to keep the chess computers of the 1970s and 80s in good working order there is usually no other option than to do it ourselves.
For general advice on repairs to reed switches and LED replacement try the Conchess page.
