Ben Eater's fantastic video series on building a breadboard 6502 based computer and an 8-bit breadboard computer from scratch might be appreciated in this thread.

6502 playlist: https://www.youtube.com/watch?v=LnzuMJLZRdU&list=PLowKtXNTBy...

8-bit build playlist: https://www.youtube.com/watch?v=HyznrdDSSGM&list=PLowKtXNTBy...

He also sells kits if one is interested in playing along.


Highly recommend Ben Eater's video, which in this embedded developer's eyes has been the clearest, best explanation of the fundamentals of a CPU as I've ever seen.


Similarly, I have come to appreciate rehsd's[0] efforts in building a 80286 computer.

Wow, that series looks fascinating!

Only watched the first video yet, after initializing itself the CPU actually runs this code (because D8-D15 is wired to zero):

  addr    opcode
  FFFFF0  90           NOP
  FFFFF1  00 90 00 90  ADD [BX+SI+9000],DL
  FFFFF5  00 90 00 90  ADD [BX+SI+9000],DL
  FFFFF9  00 90 00 90  ADD [BX+SI+9000],DL
  FFFFFD  00 90 00 --  !! general protection fault
You can see it read and write the same address three times, then fetch the interrupt 0Dh vector and push flags+CS+IP to the stack :)


Definitely agree on priority #2.

My flow for watching youtube has been to subscribe and sign up for email alerts (the bell). When I had some time to watch, I'd scan my youtube alerts email folder for items of interest. It was efficient and would quickly leave me with a queue of videos.

That workflow went away for me this month: https://support.google.com/youtube/thread/63269933?hl=en

I don't even know what the alert bell is for now. If I look at notifications its full of "recommendations". If I go to my subscriptions its random items from all my subscriptions regardless of "the bell".


A counterpoint, although perhaps an exception, to the idea that diversified law and culture results in smaller companies in Europe might be Airbus.


Another way to say 10G via an SFP+ transceiver, as opposed to 10G via twisted pair.

I just use vcsh combined with (optionally) myrepos to handle this.
