Ben Heck's Apple 1 Replica Part 1 

Wait... Woz did breakout.. Jobs just got the credit. Man, why cant the world give Woz the credit he deserves.

LOTS of inaccuracies about Steve Jobs' contribution to the development of the Apple I and Breakout. The short version of the real story is: Steve Wozniak is a genius of an electronics engineer who built (arguably) the first modern PC. He also hung out with a guy named Steve Jobs whose talents lay in business and marketing, and who once cheated him out of of some money after single-handedly developing Breakout for Atari (and as a favor to Jobs). Otherwise, good video.

Singing the montage song is so much better than an actual montage. Thanks, Ben! Made my day.

"MONITER". I laughed.

Great way to show off how you can get really close to the digital signals on a bus, and really connect the programming and the electrical side of this story. I'm definitely staying tuned for part 2!

This brings back so many memories. My first computer was the Apple ][+. This build means so much nostalgia to me. Thank you so much!

The day has come! I've been waiting so long for this video :D

Awesome. I really liked the Z80 build, so I'm stoked to see that you take such a project again.

Great configuration of wiring on the back of the processor board. Very pleasing to the iBall.

finally a proper electronics project. You get my thumbs up ben.

Mind blown. I work in IT but now I feel like I just spent a year in an Engineering course but it has only been 20 minutes. Thank you for being a great teacher I never was able to understand most of this stuff until I watched your content! I am going to build a PI into a mechanical keyboard and make a new age commodore 64.

What a great project. One of Ben's best!!

great video I was just thinking of doing my own just like this and stumbled on this video. I'm surprised I never watched it before, I thought I'd seen almost every Ben heckler episode

My gods, the wire-wrap prototype boards. The moment you started soldering breakout wires I started getting flashbacks. An Apple I is simple enough, but the Mac prototype boards were incomprehensible rats nests of glory; and choosing to use all black wires is straight baller, Ben. We don't need no labelling, here! XD

This is such a great show! Thanks Ben Heck! :)

Yes! This is the episode I always wanted after seeing the spectrum one :)

Awesome interesting video Ben. Can't wait for part 2 :) I would love to try build an Applie I or 8-bit computer myself. Thanks for the inspiration. (PS: How much harder would it be to build an Apple II from scratch, or even upgrade your Apple I to an Apple II?)

I love the skits. I'd just watch it for that, o no wait it gets even better!

As usual, great and inspiring!

This is more like it Ben! What a great project!

This us awesome. I never realized you could build something like this on a breadboard. As a software guy this just seems insanely messy and tedious! Can't wait to try it.

Great video! I really learnt a lot from it. Thanks.

This was a really interesting video! I'm looking forward to the next one. Maybe when you're done, you can make a simple custom designed computer. Maybe something with a Z80, or even a 68K!

Very interesting build Ben! Can't wait for part two. Also love the outtakes at the end of the video. How Alison could sit there with a straight face, I just don't know! I'd be busting up laughing every time! Great job as always!

Built by the Woz and sold by Jobs.

Awesome Video .. cant wait for the next part :)

Cool project, after watching this, your Atari 800 videos, and the specky project it occurred to me that it would be a really sweet project if you could make an "ultimate" 8 bit computer and combine compatibility of the popular 8 bit machines that use the 6502 processor. Maybe they could share processor, ram, and other bits, but select which machine they run at power up somehow to then tap into the other unique chips that make them all different.

That Oscilloscope is ridiculously good looking. I don't know about the measurement stage but does it come with Matlab too?

Hey Ben, i really like your videos thanks for making them and sharing so many great projects with us :) Could you please upload your schematics for your Apple 1 Replica? (Yeah i know that there are tons of schematics out there for apple1 replicas but i like this one here ). Would be really nice, thanks. :)

Hello Ben, what kind of wires do you use for this project? single strand or multiple strand? what gauge. Thanks in advance;)

This video (and others like it) is to computers, what woodworking is to furniture, or what animal husbandry is to groceries. As in: I get the general idea of what Ben Hack is doing, yet I have *no* idea how to do this myself. But I still appreciate watching skilled people go "old school", making rudimentary (and often more robust) versions of household items which I simply purchase at the store and expect to work as described. Barring the apocalypse and a reset of human progress, do we *need* do learn things like this anymore? Nope. But really do I respect people who can still grasp the basics.

Correction: It was Wozniak who did all of the stuff with the computers, Jobs was there for sales

Hey Ben, could you post the documentation that you used to design and build this? Please it would be much appreciated as I'd love to make one and I'm unable to find anything online:( Thanks

Where can you get the wires that are glued to the board(the flat ones with open metal and no insulation)

Do you have a schematic of the work you did, or are you just using the Apple 1's schematic from the user manual?

Will you be making a schematic for this board so that we can connect it correctly?

Even Ben Heck had a montage! Mooooooontaaaaaaageeeeeeee!

Cool, the Apple 1 can't wait... Love Mac always...

"Moniter"? :D By the way, why do you never use colored wire? that'd be great for distinguishing buses

Hmm. Doesn't that memory layout stop you from overwriting the IRQ, NMI and RESET vectors (iirc last 6 bytes of adress space) ?

At 5:12 you state there are 65535 bytes addressable. In fact there are 65536 [0..65535]. Please add some decouplers too! Thanks for your videos!

"we didnt need a keyboard...we didnt need a display" but you did need a $10,000 oscilloscope ;) But nice work dude.

what music do you use when you're Soldering? sounds like toe jam and earl

cant wait part 2

so that separate sheet of paper are those hex values?

More like Woz designed and built it and Jobs sold it, but OK :D

lol, I used to write in hex (machine language) until I found out assemblers existed. I think you meant an assembler and not a compiler. Great vid, brought back lots of old memories. Like when I wrote my first hex editor for disk sectors on my cp/m machine. Or debugging my microcode using a 1630d logic analyzer.

One thing I've long wondered is whether some simple wiring mods could have allowed the processor to output data to the display faster if it injected data into the shift registers at just the right time [the normal design would latch a byte of data from the CPU and then have hardware clock it into the shift register at the right time]. Even if the CPU wouldn't be fast enough to write two consecutive bytes in the same frame, it might be able to inject every tenth character or so. Apple I computers are too rare to be worth hacking with for such experiments, but a recreation that uses shift registers might be interesting to experiment with.

Cool idea, to re-build a 6502 computer;) Why you din´t go the way as all the others had gone that days built up a proto board? I´ve used the old school *wire-wrapp* method. As it´s way easier and the lacquer-coated copper is by far more easier to solder and to re-wire in case of some error(s). Here´s a little how to: Intro to Wire Wrapping And here´s what had going on with Pro wire-wrapp boards: Handmade WireWrap Card 1978 - Amazing ! Good work, anyway!

Breakout wasn't created by Steve Jobs it was Woz. Wozniac was the genius at Apple building the entire Apple 1&2 Jobs just an salesman. Better read Steve Wozniacs Biography some time.

im sill confused how o wire the chips together (ram Rom CPU)

is there schematics for this build? and where can I find them

what ROM and RAM did you used??

what's the chip that has the BASIC program?

am i the only one that just sits and and nods to everything, even though i have no clue whats being said?

What rom and ram were used?

I love this! I started as a 13 y/o in 6502 assembler on an Apple ][

Awesome. Building something old by your self. Ben you should use those "dream boards" in your videos.

>Woz hand assembled the monitor and that's insane This is actually more common than you think. I'm currently disassembling a translation patch for Telefang because, up until a year ago, we didn't have an assembler; and we don't actually know what we changed in our patches. Literally everything was done by hand. I suspect a lot of other romhack projects are handled the same way.

That intro was the best

Could we get the design files online?

How can i build my replica ? Can i get a schematic and all what i need ?

Where did Ben find the hex file?

where can I get the code to 6502?

Is there a text guide for the replica?

*TECHNICALLY*, it's 65,536 bytes. The highest possible address is 65,535. Always remember to count your zeros. :) Also, another option to make things work well would be to use a 64K (or larger) ROM chip, and put the data that's supposed to be at $C000 at $C000 in the ROM chip. It requires a bigger ROM chip (which can actually be used to your advantage later), but it keeps things nice an organized while you're debugging.

Are you going to install System 1 or so on it?

Neat. This seemed like a good place to use laser method though.

Watched this show when i was 14. My love for programming and electronic comes from jere…

The 6502 was not used in the Commodore 64. The C64 used a 6510 cpu.

Nice spray booth :)

Ben, where did you get all the components for the project?

"timer circuit" for reset? never heard of dallas econoresets (DS1813+ for example) ? i know 'timer circuits' and 'rc circuits' and contraptions with zenerdiodes were the shit in those days but there are proper reset chips around nowadays, which only take a single to92 component, that also pull reset if there are brown out conditions while it runs. timer circuits do -not- monitor the voltage. (analog devices has something simular in 8 pin narrow dip)

Ben, I bet you know what Windows 8.1 is or atleast voice recognition for 7 ya inow

So Ben, why did you spend all that time wiring the ram, rom, and cpu like that with all of those wires instead of just etching into the pub board, wouldn't it been a 1000 times easier?

Have you considered building a Sliders Timer replica? :-)

great video :D

can you guys make a schematic for one of these so your fans could try building one themselves

Where can I get schematics ??

How can we do this? Can we buy a kit somewhere?

How build own theremin?

anybody now what diodes hes using???

What's with the how-to style? I prefer the random ben heck stuff.

how much did it cost to complete this project?

Kruzader was not a part of the original Apple 1, but is a part of the Replica 1

I am genuinely concerned for Ben Heck's mental health. Some of those sounds he makes are kind of weird.

Jeez, Ben, why do you go through the trouble of hand wiring the memory like that, just make a PCB. Yea, I know, this is more flexible, but if you add an unpopulated hole to each pin of the components, it doesn't take that much more space and you have just the same flexibility to add in stuff or debug later.

cost?

Compear... It almost hurts! Well done.

I would love to be able to do what you do, but it just seems so complicated. :l

Hmm wondering where he got 6502 cpu, they seems more rare these days to find then winning a lottery..

I think that by saying "build by Steve Jobs and Steve Wozniak" he meant Wozniak build it and Jobs was watching and thinking how to sell this thing

fun fact: the Nintendo NES cpu is based on the 6502 cpu (almost identical) and manufactured by Ricoh ;D

Suggestion: Use different wire colors for address lines and data lines.

Can anyone tell me, how complicated and/or difficult it was for Jobs and Wozniak to originally make this computer? How did they program the chips for example? This seems like such a simple job for Ben, but considered they originally had to design it from scratch, it had to be a lot time consuming, right? Thanks :)

do you know where I can present a project for ben ? I realy want him to take a look a the piPhone that some Irish dude made few month ago. to make a nice case, get off want the project don't need and such. take a look : PiPhone - A Raspberry Pi based Smartphone

That oscilloscope is amazing!

are you kidding me youtube? i got a 164mbit/s connection, and you are freaking BUFFERING?! SCREW YOU RU-vid!

Why not extend this Apple board with a SD disk extension as cassette? for few bucks make it infinetly usefull.

Great!!!
