*Tech tip:* On those carbon comp resistors, check the values with a meter before installing and soldering them. Back in the late '70s/early '80s at work I discovered that a large number of them had absorbed humidity from the air and drastically changed values. If you soldered them it sealed the moisture in, but if you first baked them for a while in an oven it dried them out and returned them to within tolerance again. They could then be soldered in and the value stayed correct. This was at an electronics manufacturer, with large quantities of components on reels for automated insertion, so it was probably worst-case for a problem like this.

That's a good point (although I didn't know the mechanisms of their drift). However here resistors are probably mostly used as pullups or similar functions where the value really doesn't matter.

My main reason for mentioning it was literally a Tech Tip, something I'd run into in my career that most people wouldn't experience, but make them aware of the circumstances so if they do hopefully they'll catch on to it quicker. I'm sure there might be other reasons why carbon composition resistors might drift out of tolerance, simply aging is one. I totally agree on the fact that in this case the tolerances don't matter as much, especially if they are all the same value and things are therefore balanced out. In my case the resistors were being used in a 555 timer circuit as a power-on reset to the CPU board, and being out of tolerance screwed up the timing and made the 555 not do its job. We baked some resistors pre-installation to fix the current batch of boards, then had an engineering change to use a metal-film resistor in future boards. As for David being colorblind, I can slightly sympathize. After years of working with color-coded resistors and other components, I discovered I see a few colors differently than most. When I took a color-blindness test where you look at the colored dots in a circle, you're supposed to make out a pattern of one number if you're "normal" and another if you're color-blind. Well, I saw a third number in the pattern! Confused the doctor a bit .

Fascinating. But wait, how does soldering them "seal the moisture in" (or out)? Does moisture somehow travel up the metal leads? I don't see how that aspect could possibly be true. The rest makes sense, but surely the moisture transfers through the casing? Probably over long periods, so it would seem like they become "locked in" once baked. Also, a typical home will have better climate control than a warehouse, so they probably remain stable under consumer use, just not in warehouse storage. I bet it has nothing to do with soldering at all, but the baking prior to soldering part does make sense.

@bobblum5973

@@Havron This was 40+ years ago, and wasn't something that went through a detailed scientific analysis by any means. So far as I/we could tell at the time, it was the carbon composition (think granules packed together) that was porous enough to allow humidity to get in and affect the material. I think the majority of the casiing was coated, something like varnish. Where the resistor leads attached to the body may have been the point of entry, and the heat of soldering was high enough to seal it regardless of the state of the carbon comp inside. So a lower heat over time returned the material to the proper consistency if the moisture was allowed to escape prior to the soldering. Note that the "warehouse" was a manufacturing shop floor, heated in winter but not air conditioned in summer, so the longer the resistors were in the environment the more chance of gaining humidity. Again, this situation was just the right set of circumstances to (1) have the resistors exposed to the humidity long enough, and (2) needing a tighter tolerance on the resistance value in the circuit. After finding multiple cases of the parts being out of tolerance, replacing them with others that were also out the same way, we started looking for why, and how to resolve it. If I recall they may have dumped the reel of problem resistors and just bought a fresh supply; baking a small batch to tide us over until the new ones arrived. They were relatively inexpensive, after all.

@Havron

@@bobblum5973 Yep, that all makes sense. I agree, the point of entry probably was the edges of the casing near the leads, and I had not considered the potential sealing effect of the heat from soldering nearby.

You might be interested in working with microcontrollers then. The embedded world is pretty similar to what you're talking about - lots of choices for MCUs, sensors, I/O, etc. and you basically put them together to get exactly the system you want. You can pick up a kit with an Arduino, some breadboards and wires, a bunch of sensors, and a project book that walks you through everything for less than $100. Once you're familiar with how everything works, you can step out of the Arduino world and start working with bare chips and custom circuit boards. You don't need much in the way of coding or electronics knowledge to begin with, although the more of those you pick up the more you can do with your projects. I suspect I got the job I have today because of my tinkering around with microcontrollers in my shed. I work in industrial automation and while I don't design circuits, I have to be able to read and understand technical drawings and schematics and program PLCs. The skills I learned playing with microcontrollers gave me the edge over the other applicants that only had IT skills.

The terminal already existed. The Apple I was not designed as a computer. It was putting the computer, the microprocessor and DRAM, on the motherboard rather than calling one of the 6 far-away ARPAnet computers that the terminal had been used for. A lot of things that might be considered deficiencies were because of this 'quick' approach to show off how a modern computer should be. This was shown well before Steve Jobs knew it even existed, and all the designs were handed out freely with no copyrights. But the real machine, which would be Apple's only successful product for the first 10 years, was the Apple II, which was a computer design from the ground up. The Apple II was being shown before we ever shipped an Apple I. Also note that at this time (1975) other attempts at affordable computers had mainframes with switches and lights and the far too expensive Static Ram. It was easy to copy an Intel data sheet but you needed real engineering for a useful affordable computer.

You can identify these by the perfect cylindrical shape with a sharp cut off at each side. Modern resistors tend to be either carbon film or metal film. These are made by winding a film into a cylinder. These are the modern resistors with slight buldges at each end and a smooth transition to each edge. They're cheaper to make and I believe easier to make precise. But carbon composition still works alright.

@@WELLINGTON20 Dude if you actually watched the video he says his brother is making him a wood case. -_-

1978 in South Western Ontario Canada I started a short lived computer company called Mack Computers. We resold and customized MIPS and other early machines. Should have kept the name, if I did, I imagine i would have got a butt load from Apple to buy it as it was before they had the Macintosh or iMac computers. Oh those were the days. I still have the solder burn scars.

This was extremely interesting. I didn't know the Apple I board had basically a separate terminal and CPU section, and also it was interesting to understand how the shift registers really worked.

if you got half a million dollars in the bank you can buy an apple one or you can make an apple one replica for a whole lot less and the upside is it's brand new so it will last a whole lot longer to boot due to being brand new parts

The level of efforts you put into this was amazing.....keep up these awesome videos

It's always so respectable to see someone putting so much time and effort into something like this

Nice video! Point of order: there was almost no manufacturing done by Woz or Jobs in the garage. Woz dispelled that myth a long time ago. In an interview he stated very little was done in the garage.. it was just a 'place to go' for two guys in a new business with no money for offices. IIRC the boards had sockets and some other components wave soldered by the manufacturer (NTI, etc) and then they were stuffed later on, often by helpers.

Although, Daniel Kottke, and many others said they DID manufacture boards in the garage. Also Chuck Peddle himself also said they were making boards in Jobs's garage. In fact, Chuck said he had to go to the garage and help re-design the Apple 1 because it wasn't working. Most likely much of the Apple 1 is based on the KIM-1 besides the video circuit, which Paul Tyrell said that he heard the video circuit was based on one of HP's terminals projects. What everyone agrees on is that Woz was not in the garage much, but Jobs and the rest of the gang were there.

I got to play Hunt the Wumpus on a friend's real Apple 1. This led me to buy a KIM-1 and soon later a Rev-0 Apple 2. I loved that Apple 2 but was eventually lured away to the recently available IBM PC. (As a IBM employee I got a good price.) I continued to play with the Apple but my attention went mostly to the IBM. I still owe a lot to the Apple as it lead me into a career with computers. Those were the good days weren't they? PCs were more fun in those early'ish years. Then the internet came along and I started noticing it wasn't as much fun as it had been earlier.

Man, the Wozmon prompt really reminds of the time I tried to write my own "programming language" in Borland Delphi 3 when I was about 10. My dad was a professional programmer, and I LOVED video games, so I was desperate to get a look at how they worked. The thing I made was basically a very simple string parser, likely horribly inefficient, but you could do a bunch with it. I basically read through one of those huge manuals you used to get for Delphi and wrote a shorthand for each command that was mapped to a bigger file with the full commands in it. So you had two text boxes in the program (I think it ran on Windows 95), and you could type in a shorthand code in one, and the full command to execute in the other. So then if you entered that shorthand code again, it would look up what the full command was and run it. So for example, I had "pd" (play doom) mapped to launch Doom, and "ptr" (play tomb raider) mapped to launch Tomb Raider, for example. Today I'm a university lecturer teaching programming, so I guess that early dabbling was worth it. I just wish I could find the old hard drive it's on and take a look at my clumsy code XD

In 1976, it's amazing to think of how far they came from the Apollo Guidance Computer. The AGC Block 2 was designed in 1966, ten years prior. It was the first computer to use silicon ICs, and each IC was a dual 3-input NOR gate. It's interesting that the 74000 series DIPs are still manufactured. We don't see any retro hobbyists building rope memory or sourcing ferrrte cores... this seems to be a de-facto "starting point" for what people find approachable. I think that was true at the time as well: Computers like this APPLE could be designed and built by individuals working in the garage, while older technologies were not approachable to scales of enterprise smaller than a corporation or university.

9:56 That's crazy! That's the equivalent of designing a motherboard to take either an x86 CPU or an ARM CPU. The late 70s really were a time when "having a computer" and "being a mad scientist" were basically the same thing.

If you peek through the software in Green Delicious with wozmon or Eeben's own monitor/disassembler you can see some minimal patching where there would normally be I/O register reads and writes. Some I/O use is replaced by calls to subroutines, but IIRC $d012 writes are left unpatched. I suppose the "emulator" might attach a raster interrupt which will immediately read the line count register and output that value to the screen, which is a neat trick. I don't recall if the software it comes with was pre-patched or if this was done at load time, but I've successfully ported Eeben's monitor to a more complete emulator.
