When I joined the Army in 1974 I wanted to be an electronics technician. But due to my color blindness I ended up in a combat unit. I’ve always thought I couldn’t do electronics but I started with Arduinos and now I am assembling boards, and doing other things. That is to say, I am glad to have run into your video and see what you did. I am very inspired and thank you.

"I'd probably try to design it myself but..." And here you are almost 2 years later, designing such a thing yourself, and having a team helping out making it a reality.

"I'll be impressed when someone builds something like this that can run commodore BASIC" 2 years later "Fine I guess I'll do it"

8 bit guy: *Standard troubleshooting steps.* Me: *START UP, YOU PIECE OF CRAP!*

Who else agrees that when the chips are inserted into the sockets its super satisfying

As a professional electronics engineer, let me tell you: your tutorial is GREAT. I can't do better. Camera and macros are great. Audio dubbing: perfect. Overall very high quality. BIG thumbs up. As always. Max

More motherboards should be purple.

Yes, a big part of the appeal in building your own kits like this is the experience itself. I'm an amateur at this hobby myself, but it's always exciting to spend an hour on building up a board, plugging in the power, and having things come to life. Honestly, I've been burned, I've accidentally broken off parts, I've even been temporarily blinded by an errant solder splash, and I've had some failed kits. But, it's always fun to take a crack at one, and I'm considering picking up one of these more complex boards.

2:32 have you heared of those special sunglasses that.... 2:36 nevermind

Maybe you could make a text-adventure style version of Tetris... "You see four blocks above you, shaped like an L. It's turned 90 degrees clockwise and falling. " -> "MOVE LEFT AND MOVE LEFT AND DROP BLOCK"

I've watched this video several times and I don't mind seeing it again because the quality of his work is inspiring. It's well organized and the filming of the tiny parts is very good.

I joined the New Zealand Army in 1979 as an apprentice radio tech. There were about 6 of us that started that year. Early on in the programme we were learning resistor colour codes and all of us had the same resistor in our hands. The instructor asked one of the guys the colours on his resistor and he came up with something completely different to what we all had. Within a week, he was an apprentice vehicle mechanic.

That 6502 is not made by Western Digital, but by Western Design Center, hence the WDC in the chip.

Удачи и спасибо за проекты. Многие люди цветозрящие не готовы взяться за подобные проекты. Респект Вам!

Being a kid born in 98 and craving all these 80's and early 90's knowledge and tech makes me love this channel all too much. This is even better, making old tech out of new. Hell yeah.

Absolutely love all this obscure tech!! Watching you assemble these boards is very relaxing as well. Love your channel!

I appreciate the time you take to explain all the steps! Thanks Dave. Great video as always.

During this hard time after Hurricane Maria through Puerto Rico, your videos give me some sense of normalcy, keeps me from going insane, thank you.

This is the first time I've ever seen a board assembled. Thanks so much!

That was a cool little kit!! Cool lesson on chips, resisters, capacitors and soder advice!!! Keep up with more vids 8 bit guy!

2:06 Wow, I didn’t know you were colourblind! You did a great job with the stickers for the mini arcade machines and when you redid the lables for the cartridges

I think this board has more capability than used yet. The Parallax Propeller is a bit of a beast in this system, it has 8 32bit cores (called "cogs") and could easily handle more complex VGA (RGB) graphics.

Love your content... always look forward to any updates. Well done 8 BIt Guy!

How well-coordinated and interesting video clips come out of you. Thank you very much!

For stuff like the resistor pack I use blue tape. Easy on, easy off and it holds the part down. And I've done boards with a few hundred solder joints so no issues there.

Wow, I didn't know you're color blind. I wonder how it affects your everyday life. Thinking back you did a great job with the repro cartridge stickers, the colors were spot on even on the hand-made stickers!

The music in your videos takes me back to a time where life was so simple. love it

i love watching your videos its so fun to know how far technology has come in such a short time its amazing

1:46 You monster. Staple diagonally like a civilized person, so the corner fold follows the length of the staple.

"It turned out to be "fly".. Lovely." Elicited a chuckle, thanks.

An excellent video. Informative on so many levels, yet explained so clearly and concisely that it's easy to follow from start to finish!

Great channel! Had a Commodore 64 in 1983! Loved watching all your commodore videos! I’d love to have a “hobby computer” back in the heyday!

oh my god. how have I never thought about just measuring the damn things... I've been looking up ring codes for years!

The WDC on the 6502 chip stands for Western Design Center, not Western Digital.

putting this video together while you put a board together takes some real skill. hats off sir.

I can watch these videos all day. Great job.

I can tell you what still uses 6502, airplanes. Since they are super reliable and do not require cooling it makes them perfect to use in those applications.

"I like my chips with D.I.P." LOL! Love your shirt!

Hello Today I had watched your video about Microprocessor 6502. In 1987 I had also assembled 6502 BASIC computer. Your video remembered me my old memories. Thanks a Lot. Atul😀

You're definitely the smartest channel I've ever encountered on youtube! Seriously dude!!

I enjoyed your video on the PE6502. Having built it myself I can confirm that this is a little versatile 8 bit computer that is the best of retro and new technology. My favorite basic game on this machine has been StarTrek2003

'It's like a jigsaw puzzle for nerds' You're implying jigsaws aren't already nerdy?

That's how it all started. Learning to pay attention, and in the end being confident in matters of well thought out and coordinated action.

I like your soldering skills, especially keeping that soldering tip clean and shiny which I still couldn't achieved.

Excellent, but you CAN change individual characters on the screen despite it not having a memory-mapped display. With a serial display (as in a 'dumb terminal') a character will always be drawn to the right of the cursor, so all you need to do is move the cursor to the point on the screen before you want to display a new character. Cursor control can be effected via 'escape sequences' or 'control sequences'. I used to do this as a programmer in the 1970's onwards. I can't remember many of the control codes, but one which will always stick in my mind is 'control-G' (or '^G') to sound the bell/buzzer or, on serial-port cash registers, open the cash drawer. Some of the old dot-matrix printers, and even some daisy-wheel printers, used to respond to the same codes which allowed you to draw pictures on them.

"Hard for me despite colour blindness." *Is making game and has to make sure colours look nice.* For real, colour blindness is a real consideration when desgining something.

Awesome video, agreed it is a puzzle for nerds. That nothing is more gratifying that seeing what you make run for the first time.

I absolutely love your videos, and this one is no exception. Just a tiny hint for you from someone who has been soldering for 30 years... Try not to put the solder onto the tip first and then onto the joint. Heat the joint by placing the iron tip so it's touching both the lead and the pad, then apply the solder to the other side of the lead and pad, trying not to touch the tip at all. This will ensure a much better quality joint as you are making sure both surfaces are properly heated.

You had me at BASIC, and 115k and Hyperterminal.. Lesigh.. Nostalgia is the best..

"..It doesn't matter if resistors go one way or the other, but it is nice to put them all in the same direction..." Thanks, you saved my OCD right there. #ResistorsHavePolarity

You have probably the best KZfaq intro music of all time!

This is an incredibly well-done primer for soldering components on a PCB. So far, I’ve only done a few antenna connectors and a couple wires. I’ve been wanting to get into a bigger project (this still seems a bit too advanced for me, although your skill level made it look real easy!).

These types of kits are a lot of fun to assemble. I'd love to know when these will be available!

Watching the assembly is super satisfiieying

What a fun channel! Thank you for all of your work....my comment is that whenever I watch a kit assembly video that speaks to beginners, there's little or no commentary about the importance and usefulness of flux when soldering....and just because a lot of solder on the market has a flux core is not a reason to leave it out. I've learned the hard way to have a tube of flux available just in case it would help improve the results I'm getting! (by improving heat conduction)

Awesome! I'll get one! Nice vids, 8 bit dude!

When manipulating the leads on components, I’ve found it’s best to use something as a block to avoid stress fracturing tack welds or component internals. Usually I use a pair of tweezers as it’s easier to know exactly where I’m manipulating the lead. This process also give a more professional finish. Hope that tip helps some of you guys.

6:49 Note that you can also find pin 1 easily by looking at the corners of the housing, pin 1 is located at the pointy corner. The other corners are around.

Wow that logic board inspired me to code some hobbyist stuff to my projects, thanks!

One of the things I like to do with components that take a lot of stress of plugging and unplugging stuff is put a small drop of hot-melt glue under them. This is a tremendous help in keeping from peeling up traces on the board.

The laugh at 23:56 is such a nerdy laugh haha

I suspect there're home-build computers out there with USB and etc that you could find on eBay. They call kits like that "suites", so try searching using that keyword and also perhaps "DIY" also. They come from China on a literal "slow boat" so they don't get here quickly, but they're cheap and the people making them have VERY CHEAP access to parts you might not expect, so take a look.

the shirt alone won my subscription! great video

Your videos came up on KZfaq during some synth videos. I am not sure how many channels you have but I like the ones I have seen.

IC Socket are mainly used to keep the ICs safe from heat during soldering as most ICs are not made for handling that much heat for a long time. And of course it is used for other purposed too, which you explained in the video. Anyways, great job.

This reminds me a bunch of the Replica 1 that was produced in the late 2000's. It tried to be nearly one-to-one to the original apple 1, including expansion interfaces to plug in a casette interface card(if you have one). I haven't had a chance to work much with mine, but a project in the back of my mind has been to create a new interface card that adds in a video chip, and a rudimentary card that will allow you to play a single octave of notes on a piezo.

So thorough, even tells us the exact page printing format.

I love the socketed ICs, prevents those embarrassing overheating while soldering problems.

Great video like always

I have revisited this video a number of times as I enjoy the 8-bit guy's videos and the integration of a single board computer is just interesting to me. Some folks can work the issues of system integration to create a unique product with some older but still available technology and it is interesting to view the result. The only thing that has rubbed me wrong about the computer is the inclusion of pin style sockets for the integrated circuits ... what is wrong with providing double wipe sockets meant for dip chips with 'rectangular' pins .... sigh .... some kits probably do have double wipe sockets as it may just be a component sourcing issue at the time of kit production ... I would replace each pin socket with a double wipe socket for cheap $ and convenience.

I love watching this unfold.

Hello from Farmers Branch! The best use for extra header pins is to use in other projects to hold 3v coin cells. It fits perfectly. Nice video as usual.

Pro Tip: For reading text on tiny components, most smart phones can zoom in and focus on things that are 3-4 inches away. You can actually use a smartphone as a SMT inspection microscope. I use the Magnifier tool in the "Army Knife" Android app as it lets you control the flash as an objective light.

Best intro/music ever

thanks you are one of my top 5 youtubers and you have inspired me to make use of my raspberry pi i am starting my own retro pi project

Watching this is sooo relaxing.

Reason why your pins bend is because you bent them in on thin part instead from thick part where they come out of chip. Put them all flat on table and hold chip for casing and push up and bend them all at same time.

That's pretty funny having a Parallax Propeller as the video chip. It's way more powerful than the 6502 main CPU! It's got eight 32-bit cores which run up to 80MHz.

I had an Acorn Atom, it was my first venture into the nitty gritty of hardware and software, if anyone else remembers, it came with 1kbyte of memory for basic and 1kbyte for the display map, but what I really enjoyed about the Atom was the assembly language, remember that first basic prog for a bouncing ball?, I did that in assembly, I was blown away by the difference in speed, I even built a 16kbyte addon board for it using 6116 2kbyte static ram chips I pulled from old arcade machines, the 6502 to this day is still one of my favorite cpu's.

I also suffer the green/brown, blue/purple blindness. So frustrating sometimes. I envy you still do this.

I always measure resistors anyway. If you've got a voltage divider or something it's good to know the values are close.

Thank you 8-color guy

And now (2022 AD), some years later, the 8 Bit Guy & his team did invented a computer which runs his beloved Commodore BASIC: Commander X16! 🙋‍♂🙏👍

This guy is TOTAL KING , PURE KING , KING*KING! Love the channel!

Little tip - use a small piece of masking tape to hold the resistors in while soldering. Works great :)

It may actually be possible to connect the ACI (Apple cassette interface) to the pe6502, because like you said it has the full bus expansion port. If you (or the creator) just created an adapter from the pe’s expansion port to the Apple 1’s, and then connected the ACI, you could load programs from cassette.

Dave, I love your channel. I grew up with the Vic 20 and C64. I don't know why it took me so long to find/get around to watching this particular video. But man, for all of us that have been trained in the military as Electronics Technicians (specifically for me, in the US Navy Nuclear field), you are causing me to cringe everytime you just bend the leads on these components to make them fit on the board! Yeah, yeah, I get it, you aren't repairing a mission critical piece of equipment, but there is such a thing known as stress relief that requires you to bend at the radius of the through holes to allow for thermal expansion and contraction... Holy cow man...I know...OCD installed into my psyche by the US Navy. Lol. But I love your channel! So much nostalgia! Good stuff... Nice soldering iron by the way. I have a Haako also, but an older version. All black and comes with a key card to prevent changing the temp (meant for assembly lines)...

This seems very relaxing :D I have to learn to solder!

"This is the only diode in this entire project" A FEW MINUTES LATER "This is the power LED" ( light emitting DIODE)

19:38 Dave: OK Telix, do your stuff! 486 laptop: **shits itself** Dave: ._. umm... okay, we're using HyperTerminal for Windows instead...

A couple of tips (and yes, we make commercial stuff here). First of all, use the flux. No, flux-core solder is not enough. Yes, it will be messy and require some cleaning, but this way you can just carry the molten solder across a set of pads without handling the solder wire itself, which already is a good thing while strong and smooth joints are the actual goal, also drag soldering will become an option. By the way, if making through-hole connections, apply the flux to the both sides of the PCB (it will likely just flow through on it's own anyway, however) so while soldering a part the other side will be tinned as well (keep track on the solder - when it starts to flow down the hole, that is the moment when the part is properly connected). Also, personally myself I do never clip the pins beforehand. Instead, make some draft joints (not necessarily on every pin - just to keep each part in place, flux not really that needed at that point), then clip the pins (depends on the board, though for the common two-sided boards with plated holes I prefer to clip them very close to the surface leaving somewhat 0.3~0.5mm, not more) - and finally solder them properly (while redoing the draft joints as well). This way the bottom side will be very smooth and coating-friendly should you decide to, and you'll never cut your fingers while handling it, which is also a neat thing. Also I don't really understand placing all the ICs into sockets - should it die, you can just desolder it (which isn't that frequent nor difficult ;) ) - but using no sockets and just soldering the ICs in (even on prototypes) will save you the trouble of looking for a bad connection, also the height will be much lower (do not solder the EEPROMs and such though ;) ).

Great video! I encourage people to design and build their own. These computers are easy to understand, there are so many things you can learn. I had designed and built my own and then started to write my own operating system but it was not challenging enough so I moved to another build: the Apollo Guidance Computer, much more complicated. Unfortunately, I do not have time to share this on video :/

I have the feeling that there will be many people complaining about your soldering technique. But it is not too bad in my opinion. I used to do the same with the solder wire, move the board under it. Then, I bought a small pair of helping hands. And I tend to do it as Clive does: Hold the board, component and solder in one hand altogether... Nice project. I just ripped apart 3 old ISDN telephones tossed away by someone containing character displays with tons of datasheets for it. I am sure I could do a lot with it but I just have no real need for such a de ice at the end. To me, it is a bit more fun to see you doing all the work.

those soldering work is so satisfying to look... >

Opening the box and looking at all of the parts is almost more fun than building something :D

Out of all of those chips, the MAX232 is the one you want socketed more than any. It is the one which has sacrificial driver transistors that will die when absorbing a spike from an external serial device, instead of conducting it into the board/CPU/wherever.

Would be cool to see more stuff like this with lower cost , just with a cassette port using standard audio cables so any modern tape recorder could be used

A lego set for adults

When I construct electronics I keep one of those peak electronics LCR meters on the bench and quickly measure the component values before soldering them in. Easy if you are tired to solder in a 100k resistor instead of a 10k. Also great for checking if you have a duff electrolytic, or something is way out of tolerance. I figure it’s worth the extra time to try to get things right 1st time rather than troubleshoot later.

That is a gorgeous looking board though. Love the color.
