       | As someone who pivoted into more computing-centric work from an
       | unrelated scientific field, I can't recommend Ben's channel
       | enough! The 6502 series really helped me put together a ground-up
       | view of hardware that I don't think I could have gotten as
       | quickly anywhere else. His networking series is a banger too.
       | 
       | (I had a decent circuitry background from my intro physics
       | courses so YMMV)

         | Yeah, picked up his 6502 kit and worked through his video
         | series: burning a ROM, adding an LCD display, serial
         | communication....
         | 
         | I learned a lot.

         | 
         | His 8-bit CPU videos are just amazing, and even at ~1 Hz, it's
         | incredible to think about what all happens. And then to think
         | about going billions of times faster...

       | Great video and usually i love Ben's work, but, @ 7:48 he
       | DECrements A which is not a valid instruction on the 6502 =(

         | The CMOS version (at least the one from WDC, which he uses)
         | does have it.

           | Ahhh i see. So technicallyyyyy it's a 65C02. All good.
           | 
           | So if you're trying this code on an original 6502 it will not
           | work, but easily modifiable to use the X or Y registers
           | instead of A.

           | All the CMOS variants have it, regardless of manufacturer.
           | The manufacturer-specific instructions are:
           | 
           | - RMB/SMB/BBR/BBS - Rockwell/later WDC only
           | 
           | - WAI/STP - later WDC only
