| Block | Likely Components | How to Identify | |-------|------------------|------------------| | Power supply | 78xx regulator, bridge diode, large capacitor | Trace from DC input jack or battery connector. | | Microcontroller | 40-pin DIP (e.g., 8051, Z80, PIC16C5x) | Look for crystal (3.57–20 MHz) and ROM/EPROM nearby. | | I/O interface | RS-232 driver (MAX232), optoisolators, relays | Follow pins labeled TX/RX or J1/J2. | | Analog section | Op-amps (LM324, TL084), Zener diodes (ZD marking) | Look for potentiometers, sensor inputs. |
