There is no economic incentives that exist in the modern world to spend time debugging and fixing computer hardware to the level of analysis (excepting the hardware design phase) that Adrian does with all the retro (and now neo-retro) gear that he has videoed over the past few years. Is hard to imagine that there is anyone out there that might exceed his knack for doing such repairs.

Well DIY community moves to QA territory. Hardware industry has integrated circuit emulators for that exact reason. At some point when system scales up you can not visualize all steps at once. Very nice problem solving, you should get into commercial with these skills.

Sometimes, when you're too close, too deep, doing too many things into a project, you miss things. Happens to the best of us. Also, Kudos to you, Adrian! Troubleshooting broken, production units is very different from troubleshooting prototypes. I've seen many experienced RMA tech brought to their knees by prototypes. So, thanks for that behind the scene view and your experience!

Adrian, wow! You’ve definitely underestimated your own learning and teaching capabilities. It’s really amazing to see how far you’ve come from the beginning of your channel, right up until now. And you’re still learning a lot of things with each repair you do. It really keeps me stimulated and I really recognize a lot of myself in your way of working. Thank you for your awesome video’s!

"Like a bloodhound, Adrian jumped on the board and literally within a few days he found the source of the problem causing most of the issues ... without him I really don't know if I would have been able to put it back together" -- Kevin Williams High praise indeed. You sir, do have expertise. Passion and perseverance count 100x more in my book than any rote knowledge. What you don't know can be learned, but drive can't be taught, that comes from within.

I love how humble you are Adrian. Keep up the good work!

Years ago my friend was working on an analog neural network interface and the first pcb didn’t work while the prototype wire wrap did. He worked for two days trying to find out why and couldn’t. I told him I’d take a look and in a couple hours figured out that his prototype differed from the schematic. Two input pins were crossed. A simple program change fixed it without reworking the pcb.

Thanks really need this today. I so upset that these things are happening in our nation. I need something like your video to help settle me down. My anxiety and blood pressure as never been so high.

Adrian, wonderful, wonderful work. Glad to see you're helping them with this. One thing I'd suggest, that you ask them to add in the next revision is a plethora of test points. There's lots of space on the board, and adding little breakout pads for you to drop a scope probe (along with grounding points) would help troubleshooting a lot. You're definitely right about status LEDs though. Crucial for troubleshooting.

I love it when my favorite youtubers work together.

My very first Z80 project worked at 4MHz. Well, not worked. The clock was 4MHz. It used 2 Z80 PIO’s, and when I went to 2.5MHz, EVERYTHING worked perfectly. And that was my first introduction to timing diagrams and the unbelievable importance of making sure you understand what the manufacturer wants you to know via those diagrams. Tons of information in those diagrams. I borrowed a scope and found a LS138 I/O decoder that was fine at 2.5MHz, but too slow at 4MHz. I used another IC by another manufacturer (from Texas), and it worked at 4MHz and thus I learned (the very hard way) to read those timing diagrams. That little project is still running today. (I love the Z80. It is an outstanding processor.) Thanks for a GREAT video, Adrian! Very good to see your skills growing by leaps and bounds!!

I think you sell yourself too short. You're very skilled at what you do and I love how you explain what it is you're doing. Keep up the great work and thank you for your videos!

Leave it to Adrian’s excitement to make your day! God bless you

It seems this hobbyist is the star of the show! The others involved in this project are heaping praise on Adrian for all the help he provided. I am looking forward to the final result.

A couple of years ago I stumbled on a recommended video about a C64 that was left outside to die and you got it back to life. This was the moment that I was (hesitant at first, because why another retrochannel?) certain to subscribe, because I knew you had the absolute TALENT to troubleshoot this stuff. Measurement, measurement, measurement - not obvious location, location, location. I think 8-bit guy knew this as well, as it wasn't an accident he reached out to you.

Brilliant video Adrian... As you have observed.. Its the 2nd set of eyes... Love the fact that its all my favourite retro KZread R's collaborating on this project.. Also love the fact that it will be ATX compatible.. When it gets to production.. There will definitely be a sale here!!

Congrats on getting to the bottom of the Commander X-16 issues!!! I'm sure you have really helped get that project going again!!

Happy to see this, watched *TexElec* discuss you helping him out on this and was hoping for an update from you. Thanks for posting. Cheers,

This is such a beautiful piece of hardware. I'm overjoyed to finally see a fully-assembled example! Everyone did a fantastic job!

Glad to know you're helping with this project! Happy New Year!

Wow, great job Adrian! I’m very excited about this project and would like to get an X16 someday. You really proved the “second set of eyes” effect.

Hopefully Adrian will get an acknowledgment silkscreened on the final production boards.

Got to say I find your debugging/repair videos the most interesting and I learn the most from them - and I'm so glad you got to do the video on the X16. As soon as I saw Kevin's comment that you had diagnosed the issue I was keen to see a video with the details of what you'd found. So thanks for the time and effort you put into these! Cheers.

Well done Adrian. Happy to see this project moving forward.

Adrian, you are too modest. You are an excellent diagnostician.

Congratulations on becoming an X16 Commando.

I love that you helped on this project! So much looking forward seeing this project happen!

You are a wizard, and you haven't even needed to use deoxit. ;)

That's awesome work. It certainly seems like troubleshooting a design that's never worked would be a much more daunting task than troubleshooting the average production board that's failed.

Well I confess, I'd never heard of it, so curiosity made me Google for it before watching your video. What an interesting project and I'm thrilled to see you are involved in it. A great job troubleshooting this. It's hard enough when you know how it's meant to work and perhaps have a working computer to compare against. I imagine it must be really hard when you have only one of 2 that exists. You are very modest about your skills really, I don't think many people have the skills, patience and tenacity to work out these problems and fix them. Awesome job Adrian and a nice relaxing video to hear you talking about it.

Such an awesome video. I sure has been wondering about whatever happened to the Commander X16. Now I know :) and This was indeed great news, aspects and valuable information. Thanks Adrian for making this stunning video.

Anyway, hopefully they can make some good progress on the project now this hurdle is cleared. Can't wait to see what kind of games people can make for it!

When a supposed "amateur" (with a bag of skills larger than many supposed "experts") has way, way more energy and enthusiasm than the ideator of the project itself. You would expect the 8-but guy to be announcing this actual huge milestone (well, his last statement about the project was a laconic "the second revision board does not know and we don't know why") and instead, nothing. Well, I guess he's too busy to follow his own project as a leader, oh well :D On a brighter note, Adam: yours is one of the most entertaining and educative channels about retrocomputing and your skills seem to be ever growing. Well done, you are an inspiration.

I think this may be a bit unfair. I think when you work on a pet project for such a long time that you're really excited about, it can be extremely disheartening when you run into debugging roadblocks like this that have you running in circles. Such an emotional gut punch would explain David's terse statement and apparent lack of enthusiasm. I'm positive that David, et. al. have great appreciation for Adrian's assistance and a renewed excitement to get this computer produced and out the door.

This video shows that good troubleshooting skills will allow you to become an expert in most fields you apply them to. Well done Adrian!

It is so easy to go down the rabbit-hole and that is where that second pair of eyes is invaluable. Well done Mr B!

Sometimes when things comes mad as this. Not knowing all the details on what were tried to troubleshoot it is a blessing. Thanks for sharing it!

So exciting to see some more progress on this!

Actually one of the earliest VERA prototypes was installed in a C64 cartridge and David Murry showed us it running on the c64.

Thanks for your help to get this beast working these are exiting times indeed.

As far as I'm concerned, you're a hero. I have often run into problems where I just needed a different set of eyeballs on it. And it was almost better NOT to tell the person what my suspicions were as to the problem. Outstanding work on your part and also, Kudos to the entire team, because this is going to be a great project. All good wishes!

Its weird 10/12 years ago I used to see Kevin almost every day at work.

Loved this video Adrian! I've been reliving my youth by watching retro PET/C64 & Amiga videos!

This is proper garden shed computing and its fascinating to watch. can't wait to see the finished project

Very enjoyable 41 minutes. I had wondered where this project stood. Great to hear another enthusiasts opinion on this device. And while I have seen this channel floating around. This is my first time checking it out. Nice place to start.

I'm continuously fascinated by how much Adrian knows about vintage technology, but not just from a historical perspective. It's knowing how the vintage tech works at such fundamental levels. Right down to even understanding what the pins do and how the ICs function. I love being educated about it.

I used to be an auto mechanic but your videos having me repairing TVs and computers

Oh heck yeah! I was hoping you would post a video about this.

Adrian, thanks for donating your time to the Commander X16. I'm so excited about this project!!!

Very good example of the team effort method! Sharing knowledge and experience so everyone improves. As for the bad IC socket issue, long ago I learned to never scrimp on cheap sockets. Working at an electronics manufacturer in the '70s & '80s we bought enough Texas Instruments chips that they practically gave us free sockets. But after having long sessions troubleshooting and replacing intermittent sockets, we re-spec'd the board to use machined contact sockets. They cost appreciably more, but much less in the long run, never had a socket related problem again.

I love the case mockup on their homepage, looking forward to this.

You are awesome Adrian. Watched the other video and so excited to watch your video. Well done Sir.

I wish I could find a car mechanic who is "not an expert" in a similar way... I love your videos, even if I don't understand everything:) Love from Hungary!

I think you’ve more than earned yourself a spot in one of the first production run Easter Eggs.

cool! Great Job! waiting here for the command X16 to come out.

The notion that we might actually get the Commander 16 is pretty exciting. Most "new" retro machines don't tend to get too far, and the few that do make it to production tend to be pretty niche in terms of what they can do to justify their cost (the Gigatron and PE6502 leap to mind there). Many thanks for your help in keeping this excellent project afloat, hoping to have one of my own someday! Further, yeah, now that you mention it I absolutely want that FPGA graphics board in my IIGS.

Really enjoyed the video! I can relate about the correct timing, voltage etc with my own projects! I wasn't aware that some chips need to be synced with the system clock, thanks for pointing that out! Great job on the issue hunting, a no assumption strategy often works best!

Love it! I can't wait to see this live.

Really exciting project. Time to learn 6502 assembler.

Thank you, it really does help me see the whole picture and your animated hands made the explanations all work :D

As a communications Tech for 35 years, troubleshooting very complicated systems, a 2nd set of eyes on the trouble was golden and a must some times, it was like with 2 people working on the same problem just made it easy to figure out , plus it was alot of fun coming up with the fix. Always thought it was interesting how every tech troubleshoots differently, tho we were all trained the same. Guess its just how the brain works.

I'm glad you made the BBC micro comparison, it was all I could think about while you were describing the circuit. And if you want to do some 6502 assembly and diagnostics, just fire up a BEEB it has a 3 pass in-line assembler built right into the basic interpreter and 6522 "user port" that could easily be used to program a EEPROM. The BEEB was also the machine that hosted the ARM development system so it has some pedigree!:-)

goodness used to design TTL circuits back in the day, timing, and transition states is the bomb on this, yep the bbc micro is a classic example of how to manage timing transitions etc, you have to be real careful, which it sounds like you have, so kudos. Kevin must be in a big forest full of many trees, extra eye are always welcome great video Adrian. they need to reward you in gummy bears! Blinken lights would help (like the gigatron?)

Sounds good. Thank you for your efforts Adrian.

I had no idea you were working with a project like this, that's really cool

It's such a cool project and I learned so much when worked on the iOS port of the Commander X16 emulator. It's my favored retro inspired computer and can't wait until it's available. Youre genius guys, really!

Great Vid! amazing how doing your own thing can get you past the other guy's hangups/misdiagnosis, even when you know less about their design. I guess it shows how much "builder bias" piles up as they're designing the board.

Thanks Adrian, I love your short videos :)

I know nothing about computers. I barely know how to watch KZread on my Chromebook. This video helped me understand so much about the circuitry of the stuff that I am working to trying to build. I am mentally disabled, 66 years old and in an assisted living facility. My only workspace is on the seat of my walker next to my bed.

It's such a cool project, thanks for the in-depth look! When I was in college, we had a digital design class; the final project was to design and implement a 4 bit processor (using all discrete logic gates!!) that could execute a shift-and-add algorithm to do a multiply. TIMING was THE problem; synchronizing between the ALU, the memory, and the 3rd part (whose name I forget) - anyway the group that got the closest could get any 2 of the subsystems talking, but not all 3 at once. TIMING, as they say, is EVERYTHING :)

Thanks for being involved! I'm really excited about this computer and I feel like I know the layout much better now. I wonder if some of the glue logic could possibly be replaced with a pair of GALs? Also I really love the two new camera angles I think they work really well and I hope you keep using them!
