A manchester-encoded bit 1 is a low-to-high transition: there should be "low" on the line which will change to "high". Before the "low" the line was idle (zero voltage difference), this state is interpreted by

The preamble is intended for synchronization, the last two consequtive ones indicate the start of the data. My circuit doesn't drop any frames, it simply converts serial Ethernet signal to SPI. FCS and MAC checking is done in software

Do you think they are worth mentioning? My post isn't a tutorial.

Yes, but this is only the case with 10BASE-T. Modern standards use more complicated Fast Link Pulses.

It's a fun project. I feel like building stuff with logic gates.

The preambles were longer by a few bits (even less than 8). I didn't check which frames excatly caused this, but it happened only with one old 10 MBit switch.

I used Falstad curcuit simulator ( https://www.falstad.com/circuit/circuitjs.html ) to try out some subcircuits (monostable, for example) and then tried them out on a breadboard.

Looks interesting. How are closures implemented? Is it possible to use Ante without heap? Are function arguments passed by value?

I'm a Russian in Germany. I've fled Russia after Crimea/Donbass events because of Putin's politics. No Russian I know in Germany or any other country abroad supports Putin.
