In this video we get an overview of the real-time clock solution from Mountain Hardware designed for the Apple II. This card is from 1978 and is a true testament to the expandability of the Apple II system even though it didn't come with RTC functionality. We change the card's backup battery and set the time with provided software. 00:00 Intro 00:27 The Mountain ClockCard 01:14 Changing the Bat...

Apple II Plays a DIY Modular Synthesizer
I love the design of this computer. Do you have a instagram with any more info that I could follow?
Damn. A huge undertaking. Great job, man. & thanks for sharing. Keep rockin'
Nice work!
To be clear: Mr. Big is a character on Sex and the City (which I also have not seen). Big is the movie with Tom Hanks 😆 both of these have ever-slipped beneath my cultural radar. Apologies.
Hey, I absolutely loved your robot project! The detailed explanations and the complexity of the build were truly inspiring. The way you integrated multiple Arduinos and a Raspberry Pi to control the eyes, mouth, and Cylon effect was amazing. The robotic hand and the expressive face add a fantastic interactive element. Thank you for sharing your knowledge and inspiring budding engineers like me. Looking forward to more awesome content from you!
Thank you for your kind words. I hope to indeed bring the channel more updates as I develop this machine and work through many other projects! Thanks so much for watching ❤️
Very cool. When I started with digital electronics, I made my own Z80 board with hand-soldered wires. I had the CPU, ROM, RAM, PIO, and Serial on a single board. I have always wanted to make a modular card slot version, just as you've done, but I never did more than in-head design brainstorming. Being able to turn ideas into reality is an important skill. Well done!
thank you for your kind compliment. I think after a year or so of using this machine that its reliability over time, especially in my humid climate where oxidization occurs readily, is at stake given so many hand wired signals. I have to spray deoxit often to get it back to life lol. Your singleboard solution is probably best especially if one leverages such services these days PCBWay, but certainly i continue to enjoy the learning tool that this machine has become. Thanks for watching!
You need to take a look at the TEC-1G if you think a SBC can’t be upgrades or have connection options. 😂
whoaaa this is really cool. i may even get one to play around with. thanks for informing me of it!
i'd buy your book on this!
Wikid Nice Project; New Sub, Drdyen, Mich. Wish I knew how to get my Brain to function, I have projects galore but nothing this intense. Well Done Sir!
thank you for the kind comment! i plan on getting back to more posts soon. life has a funny way of lifing which distracts from projects. stay tuned!
cant find the edge PCB prototype boards. 😑😒
you gotta get them fabricated yourself. the link which has the necessary files in on the page in linked in the comments. but here is a link to the gerber files directly wrcooke.net/classiccomputer/vicproto/VICProto_fixed.zip
@@joshuacolemanmakes7518 ty ill try it
Awesome project, looks sweet!!! have you rotated the first tube to align it with the others yet??....that messed with my O.C.D😯
lol indeed it has been fixed. OCD satisfied.
That is so cool !
I would have used a toggle switch for the cpu speed setting, but the tried and tested jumper way works just fine.
Nice job, I just finished building one from a kit, but couldn’t imagine building one from scratch!
you'll be itching to get down to it sooner or later! good luck and thanks for watching.
The LEDs are too bright
agree. plus blue isn't period correct. I'm going to rectify that soon!
Nice👌😎👍 ❗ I suppose the values of data and address are displayed hexadecimal, what IC is used to translate binary to seven segment❓
These displays have internal logic to them that does the translation from 4 bits of Binary to it's Hex value. They are called the TIL311 from Texas Instruments. They're a vintage 70s part and pretty useful for these kind's of computers I think. Thanks for watching!
24:00 Get it to say "By your command". I was expecting to evoke memories of the Speek&Spell, but my first impression was that of the (original 1970's) Cylon voice.
yes i was incorrect about the chip being from speak and spell. i will try your suggestion phrase and perhaps make it a short and tag you!
Use a ready available super power and make your own PCBs, KiCat and JLCPCB. Hand wiring your boards isn't necessary any more.
I believe you fail to understand this project if you consider any of this "necessary". Hand-wiring was half of the fun! Thanks for watching.
i love your videos😃
Beatyfull ¡🎉
Старый добрый Крафт Вэрк-легенда!!!!!!!!
Nice rig. I’d like to learn more about the design. I am into retro-computing. On a side note. I ❤ Kraftwerk. The Model and Trans Europe Express are my favorite songs by them. Nice choice of music.
Just head to my channel and you'll see a whole video about the computer and the process!
You are a legend!
😊
Great job! 👍
Nice job I would suggest checking out the Surfy Bear compact reverb tank, then you could use it with any amp or even direct into a DAW
Great! Nixies are such fun to add to projects and clocks seem popular at the moment! Just wondering - I may have miss seen it - but your mains input plug does not look rated for 100+ Volts. Are you sure it is and therefore safe to use?
These aviation connectors are rated at 125VAC at 5 Amps. Therefore they are indeed safe for US mains applications. Thanks for watching!
Здорово! Мне тоже было интересно изучать архитектуру 4004 процессора, это очень интересно. Далее изучу Z80 )). Сейчас изучаю FFD дисковую систему, как обрабатывать, записывать и читать сигналы с магнитного диска. Это очень интересно! Спасибо за видео и удивительную атмосферу!
Крутой компьютер! Спасибо за демонстрацию.
Super!
Thats awesome! Great explantion of your fantastic computer project. Very well done! 👏 👍🙂
Thank you very much!
おお😮！やっと帰ってきた😊おかえりなさい 私はこの投稿を待ち続けてました
🙏🏼
**Correction: Tl used their own LPS-based speech chip - the TMC0280 in the Speak N Spell. This one sounds very different from the allophone / phoneme-based SP0256, and is much more versatile. Please forgive the inaccuracy.**
This...this is good...this is material we need more of on UA-cam.
That is not the speech chip that was in the Speak & Spell.
Someone pointed that out and I’ve corrected the info in the description.
@@joshuacolemanmakes7518 Sorry. I only watched the video.
Reminder: protogens go beep boop
Very nice! Keep posting updates!
Thank you! Will do!
Man I love the sound of that chip. I could leave that part on repeat all day.
That is beautiful. Particularly the insides! I would describe this as the most beautiful RC2014 kit I didn't make :-)
Wow, thank you! High marks from the man himself. I’m glad you think it puts the RC2014 to good use.
Agree
Could you say a bit about the enclosure? The top looks like a single, bent acrylic piece. How did you make it? What is the bottom made of? Is there a metal cage of some sort? How was that made?
I realize this may be a deficit in my video so I think I’ll do a follow up that talks about that process. Stay tuned and thanks for watching. ❤
Very nice build, congrats!
Very nice build
Das blinken lights! Cool machine dude!
Awesome work, I love your general implementation, mechanical work and how you have had pimped out your machine :) Also thanks for all the links and explanation.
Nice, very nice !!
Beautiful !!
Thank you!
Nice I love the blinken lights and switches, been wanting to build something similar myself.
Great job(1), it would be more interesting, to create a drive that(store's) 1024mb with added error_correct(feature). Though it would take a long long long long, long time to create such a "marvel" of engineering.
Why did you need to communicate wit hthe sound IC using the 8255 instead of the bus, like you did with the LCD?
this whole computer was an exercise. i just wanted to see if i could do things sometimes. I wasn't ever choosing the most convenient route. thanks for watching!
This reminds me of the Sega G80 cage system ...Z80 cpu card, rom card , sound card , speech synthesis card, raster graphics card or vector graphics card . Some great games on that system.
Nice clock, obviously telling time back then was only for the rich people. By the way, ask your neighbour to play his Hammond organ not so loud!
