Building a 6502 computer: Episode 4, binary and hexadecimal (8 bit, apple, acorn, atari, commodore)

Theory video explaining the common number systems you encounter when working at a low level with computers.

Note: These are not the ones I'm using in the videos, I'm using BusBoard ones not Elegoo. Busboard are much more expensive but are highly rated. The Elegoo are probably fine, I've used other cheap breadboards lots of times and been fine but for full disclosure I cannot vouch for these particular ones. If you can, order from US Amazon, which does Busboard. That's where I get mine from. The process is just like ordering from UK.

Ways to say thank you

Use the Super Thanks Button (if available) under the video

Patreons have access to all videos early plus can view all the posts on Patreon. There are other rewards if you're interested. If you just want to watch videos then that's also fantastic because without people viewing I wouldn't even do half of what I do. So thanks very much :)

Similarly you then jump to hexadecimal without any mention of octal which was used extensively in computing until hexadecimal took over. Early computers did not use standard sizes for data widths and multiples of 3 bits were more common than 4 bits. The big problem with octal is that it can easily be confused with decimal when written down and hexadecimal much less so.
Of course to cover this fully you would have had to double the length of this video :)

An excellent intro!!! Love your thorough descriptions. Am currently designing and building a super KIM 1 using a real 6502 but replacing all external signals and emulating memory all via an arduino MEGA. All GUI via an LCD/Touch on an RPI that sends commands and receives 6502 data & output signals from the MEGA. On the RPI driving the super "KIM-1" interface with Python 3. Observing your build gave me some additional ideas. Thank you.
