These spare parts were purchased from Peter Roberts, who worked as repairman for Competence, the distributor of Fidelity chess computers in the UK, through most of the 1980s and 90s. They appear to be mostly unused components in good condition (obvious exceptions noted) and should be in working order. Peter Roberts himself had no Eprom copying or testing equipment, so the ROMs are as supplied by Fidelity. Some may have been damaged or lost their data over the years. I have no facility for testing these components, or inclination to do so. So if you order an item it will be at your own risk.

The items are available to known owners of the chess computer models concerned as replacement parts. Most for only a nominal charge to cover packaging, plus the actual shipping cost to you. Some components, eg program ROMs for the more valuable Fidelitys such as Elites, Mach IIIs and IVs, will be charged at a ‘commercial price’*. This is to discourage multiple requests, and particularly those from modders and traders. The intention is to provide a long term resource for the chess computer community to help keep the old machines going.

*refund on return if they are faulty

The list below is a first draft and shows numbers, part reference number, date stamp (can vary) and model / rom info.
Corrections and further information, particularly matching part numbers to Fidelity models etc, will be very welcome.
 

ROMs for the Early Fidelitys  (including CC3, CC10, CC7, Voice, Advanced Voice, Bridge, Sensory 8, Voice Sensory, Champion etc) Some chips are found in several models. For a useful source of information see MESS emulation data.
