I'm sure a repair and servicing manual existed, but I haven't found one, or even a mention of one. Even obtaining the mil spec for the CADC was a big effort.
As far as servicing, the official specification is "The computer shall have a reliable life of 1,000 hours with reasonable servicing and shall be designed to have a minimum operating life of 5,000 hours with reasonable servicing and replacement of parts. The computer shall have a mean life of at least 300 hours."
- jacquesm 3y agoCan you explain why the mean life is so much smaller than the reliable or operating life? Or was that meant to be 3000 hours?
- kens 3y ago"Mean life" is essentially MTBF, the average time during testing until the system malfunctions, at which point the system is serviced and testing continues. The "reliable life" is the life with servicing, so it is longer.
- jacquesm 3y agoAh I see, thank you. Given the complexity of the device and the amount of mechanical bits and pieces in there these numbers are very impressive even if they might seem low compared to solid state.
