That early camera was compact and had a flash but did not have zoom. The flash only worked as long as the AC adapter was connected. The pictures were stored in the camera's internal memory and downloaded to a computer. The new Mavica cameras are loaded with features and can store pictures in one of three formats: · Floppy disc · Memory stick · Recordable CD (CDR) The most popular format at this time is the floppy disc because of its versatility. The alternate formats offer increased resolution and more picture storage as we move away from the smaller storage capacity of floppy discs. · · · · · Precautions from High Voltage Normal operation and model features How to use the (RM-95 and Radar W) memory access jigs Circuit Operation Important adjustments Electronic Contents of Mavica The MVC-FD85 is the representative model because of its popularity. The MVC-FD90 and MVC-FD95 models are similar except for features. The MVC-FD95 has a different lens assembly and electronic viewfinder so it looks different from the front. Troubleshooting and disassembly are the same for all these popular models. The main FC-72 board in all three of these models contains a Ball Grid Array (BGA) IC. BGA ICs require expensive equipment and time to replace. To avoid purchasing this equipment, the main board is replaced if found bad. There are other assemblies replaced as a unit. See the chart. Note that an internal rechargeable date/time battery on the PK board has replaced the traditional date/time coin battery.
