Not to say people can’t be proud of what they make, but they should acknowledge they aren’t an engineer. Once again only some people.

The kit itself is exactly what I've been looking forward to, equipped with every component needed for assembly. Your projects have always been a source of inspiration for me, and this experience has only amplified my enthusiasm.
    Your work not only educates but also builds a community of curious minds. I’m more excited than ever to be a part of this journey and to see where this newfound inspiration takes me.

      I did the same. First programmed in BASIC on a TRS-80 in 6th grade, and when I got my own home computer, the Atari 800, guessing around 1982, I started doing 6502 stuff. I remember hooking servo motors up to the joystick ports and controlling their position with 6502 code. IIRC the joystick ports were serial i/o. I would have been 13 yo at that time.
      When I made the move to the Atari ST, 68000 based, man, that was so much easier programming than 6502!!

The only tool was an analogue voltmeter which told you 'low', 'high' or 'changing'. It took me a week to get the LED to light up. Having done that, progress quickened. Every function I wrote did something different with the LED so I could track if it had worked or not. I kept going until I could bitbang asynch serial data to an old VT100 terminal.

    I remember doing something like this in University. We had to build full system with a 68000 processor, boot power circuit, ram/eprom(for the program), two serial ports. Then when that was working, we had to write an actual multitasking OS in assembly code from scratch that had interrupt driven drivers for the serial ports, that we can pass messages between the the serial ports. And all of it done in 3 months, this was even before Linux had kernel 0.8 Lots of fun.. some of the student boards had so many weird problems, one of them only work if you put your finger at an exact spot of on the bread board. THIS was never attempted by subsequent generations of students. I was in the pioneer batch of a new school in a Singapore's Nanyang Technological University and we had lectures from around to world to come and question us for 3 years to gain accreditation. Fun times. This was done in second year of the uni. 1990. That degree was designed to bridge the gap between electrical/electronic engineers and computer science.

      This video is pretty much the most simple explanation of how a microprocessor operates. Since you're struggling, here's a reasonably short clarification. On reset, the chip goes to a default memory address to start reading a program - in machine code. To do this, it sets all the 16-bit address bus pins to the memory address it wants, and then sets the I/O pin to "read". Data flows in via the 8-bit data bus. The value it reads is interpreted as an instruction, and it performs that operation. Here, Ben has it performing a NOP or "no operation" - i.e. do nothing. The chip then goes to get the next instruction, another NOP, and so on. The magic really starts to happen when a real program is loaded, but to do that Ben needs to wire up some memory (he mentions a ROM, or read only memory). For just a couple of seconds, the chart of chip set operation codes was on screen, listing all the possible actions the chip can perform. A little more detail is needed about the chip's internal architecture to understand exactly how it does stuff, but I'm hoping Ben covers that in part 2.

Thought I would hate this CPU because they did crazy things like use low ram memory for registers and register commands that worked there instead of the CPU and was writing real time code where timing really mattered.
    Sheesh, once I got the hang of it I thought everybody ought to work it that way. This was especially true if you were a C programmer because of the similarities in pointer uses. I would map out register space and go for it, no pushes/pops - just a fetch instead of hmmm.. dang it where was that crap I left on the stack... rats, I just drove the stack into the basement!!

    I like how each time you change your code, you run it and show what it’s doing each step of the way. It’s a lot more helpful than just showing the finished code and what it does. I mean, I still don’t understand it, but I don’t understand it a bit less than usual lol

    Hi Ben, I've actually seen this done on a Z80, on a massive single breadboard, when I was at Marconi, back in the day.
    I had recently finished a three month microprocessors course, so I was even more in awe of it at the time.
    You explanations are great. Keep up the good work.
    The odd comments you have, are only to be expected, as electronics is chock-full of abstract subjects, that most people are neither aware of, nor understand.
