Age verification? I soldered my first computer from a kit. It was 8 bits, had 1024 bytes of SDRAM, and ran at 3.58MHz. Computer network, riding my bicycle to the library and copying code from a magazine. Writing a program, writing out the assembly instructions, converting them to hexadecimal, and typing in a monitor program for the CPU to read the keyboard so I could enter more programs. Building a radio, a trans istor was optional, but a diode and long antenna was required.
