[edit]DescriptionRevox B215 control PCB - microcontrollers.jpg |
Русский: Плата управления деки Revox B215. Три однотипных микроконтроллера Philips MAB 8440, живущие на общей шине. English: The three Philips MAB8440 microcontrollers of the Revox 215B cassette deck, and a proprietary EEPROM with a version tag on the right. It's all synced to a common 6MHz quartz, and connected with an I2C bus (another Philips design), which was sort of novelty then (1985). |
