7:02 ATX specs don't seem to have that labelled as PWR_ON, but either 'Power Good' or 'PWR_OK', which is vastly less confusing. I wondered why I didn't recognise it. Thanks for the Battleships style chip labelling tip, a good idea

Well done! Serious kudos!

Imagine showing up to the LAN party with this

That is sick

Awesome project! Like you, I was enamoured by computing since the early 80s. Inspired by reading about the legends and pioneers of microcomputing like Woz, I wanted to build my own computer but thought it would be out of reach. But in the last few years I saw a number of projects including Ben Eater etc. which gave me the confidence to try. I have a fully fledged machine on breadboard (graphics, sound, storage, unique programming language). I'll always keep it like this but the next step could be to make a PCB version, for posterity! Good luck with your project!

I have no idea what is going on

lord british smites the capacitors

Looks awesome, Eric. 😎

The chip tune music is called time test?

Building a homebrew computer & getting into the ultima games is something I want to try 😊 👍🏾

Super amazing!!!!! That rocks!

Super cool!

epic.

I'm interested in owning a Lode Runner (just the PCB board) Appliance.

my favorite game of all time. My mom used to play it so much it drove my Dad crazy LOL. but she made thru all levels, and she mastered the game.

Wow, thanks for the shoutout! I'm humbled. I somehow missed your last several videos. I love the progress you have made and props for sharing with everyone! I now have the pleasure of binge watching your progress! Lucky me! Please keep it up, can't wait to see the final PCB version and what can be done with it!

That's a lot of components on one board. Fingers crossed that it will work! Getting a working PCB up and running is a great feeling!

You know if you did this with a C64 you could fill a breadbin with breadboards. Just sayin' (-:

You need to build a keyboard that matches your 'motherboard' (-:

You should add ground vias in proximity to any signal via.

That is awesome, can't wait to the board, nice job!

I just got PCBs working for my own home-built 6502. My ears pricked up when you mentioned a port of frotz. Do you have your port available online, any pointers to where you started, or suggestions?

A long time ago I built a 6502 computer using PCB's from OSI. Back around 1976 or so, it had 16K ram (I got a good deal on 2102's in bulk) on 4 boards. I had the MOS Technology TIM monitor, and Tom Pitman's Tiny basic. I'd like to build a more modern 6502 machine, but designed around the WDC65C816 chip, which is the same one used in the Apple IIGS. A RPi Pico could do the video and sound.

Is there any chance you would have an alternative PCB layout with all through-hole components? Some of us (me) are too visually impaired/old to deal with SMD.

5:47 A 6502 based computer inside such a modern case would be pretty interesting

Holy Breadboard Hell! My Old ADHD/Autistic/dyslexic/... Just Fizzled My Brain LOL Thats AWESOME!

Great work! As a Signal Integrity guy, I'll caution you may end up with problems with your signal/GND/PWR/signal stackup. The speed of your board is determined by the speed of the logic transitions and not the speed of the clocks, so even retro projects with modern chips can end up with major SI issues. The problem is where signals are referenced to. 100% of the energy in a signal is contained within the electric field which exists in the dielectric of the PCB, not the trace itself. As you swap sides and use the power and ground planes for reference, your SI will get clobbered. There's an easy fix which will just about guarantee eliminating SI issues if they crop up here which is to switch to a 6 layer with a SIG/GND/PWR/PWR/GND/SIG stackup and use a 2nd ground via to join the ground planes right next to any signal via. As the signal switches sides it will be momentarily referenced to the GND via and the relationship to GND will remain constant along with the signal integrity. PS: I'm convinced there is no autorouter available for less then $200,000 which is worth a hill of beans. Always hand route for best results.

Awesome. I completed the Ben Eater 6502 computer on breadboard during lockdown which i still have. I loved building it. I did briefly think about transferring it to PCB.

Awesome project. I can hardly wait to see how the boards turn out!

Very sweet. I love seeing a design come together on a PCB. Edit: A shame you didn't route it by hand. I find it very meditative and satisfying.

Nice.

Incredible work!! Very well done. Kid love to buy one of your lode runner emulator boxes!

impressive

Supercool.

Please say you'll be porting Ultima to the X16

Unmistakebly the sound of the Mockingboard, the ordinary Apple II could not make music with that speed.

Super cool! The break key looks a little lonely though 😂

Anyone who designs a 6502 based computer is a legend 🙌🏾 in my book

Awesome!

Wow... great work!

omg geil

amazing level of skill and work done there. wow

impedance go brrrrr

haha... awesome!

is that like pc computer or amiga commode or video game Atari ?

Great video!

Nice!

this is amazing!!

It is fantastic, fabulous, great! The Apple II was my first computer with a keyboard and a cabinet all others before that had only a pcb and some LED's. The Apple II was magnificent, the strange dots ment colour, the clicks ment music. You had to have a lot of imagination to play a game, it was just enough what the Apple II showed to give the illusion of a game. For me the Apple II will always be special. Remaking the Apple II could remove the limitations of the system. This is fantastic.

does this emulate the apple 2 itself?
