My discrete computer lacks two major things: sound and network. The project I describe here is the first step to making it capable of network communication. I don’t touch the computer itself now, but instead build a transceiver which converts a 10BASE-T Ethernet signal to SPI and back. I use an STM32 MCU to test my transceiver for now. In the future I plan to connect the transceiver to the discrete computer.
