Ask Adam - Ep1

1st video in a new series where I answer viewer's technical questions I've received during the week. In this video we tackle:
Xmen whose coin input is always on
Horiz/Vert pots used on DK and DK JR
Horizontal and Vertical counters
Super Punch that won't coin up
Overview of my test bench setup
Brief Pole Position Clone update

[@carriez5969]

As always, you have produced a fantastic video. I love the new series! THANK YOU for taking the time to do it!! Oh, and of course loved the bloopers at the end. ;)

[@banjoguyollie]

great. you've a fantastic way of explaining things. After watching all your board fixing video, I got me a logic probe and a few other bits and managed to source and fix one of my arkanoid board

[@markafore]

Ask Adam is a great addition to your channel. I wouldn't mind seeing more of them. Keep up the great work and thanks for all you do.

[@evilash570]

Yessss! I love this! Im a huge fan of john's viewer mail segment, and the detail in which you explain arcade schematics, and trouble shooting is excellent, i've learned so much! Thanks again!

[@kcase601]

Love the videos and thanks for the help. Just what I was looking for. Keep up the good work you are awesome. I never ordered from mouser because it was hard to understand how to order from them. You explained in plain English and was very easy to understand. Thanks again!

[@seansretroverse9082]

I love it! This is such a great format! Thanks for going in this direction, Adam! I have a question about a couple of games with playfield (background) corruption (vertical lines, etc), so that future video you mentioned about how arcade video works would be fantastic. It would be great to cover multiplexers, color and graphic roms, screen ram, how its shared with the CPU, etc etc.. Now I am psyched up! Keep up the great content! God Bless!

[@shovelhedded]

Really great new series! Thanks Adam, great stuff.

[@joesmoe71]

Terrific idea for a series! I'm looking forward to watching these and will probably have some questions of my own eventually!

[@HappyAtom]

Awesome! First question you answered was what I wanted to ask. I have a Defender that keeps moving the ship down even when the control panel is disconnected. I pined the problem to the tiny IO board. It has the Resistors and Caps just like you talked about. You said I can use a voltmeter to test it. 9:30 So 0 is a good reading, what is a bad reading on the voltmeter? Anything above zero I guess?

[@onecircuit]

+HappyAtom No 0 means the signal is being grounded all the time. That should only happen when you are moving the joystick. If you aren't then you should expect to see something close to 5v

[@HappyAtom]

Thank you so much! I can't believe the timing of your video! You are awesome for taking the time to do this. I will let you know what I find.

[@rmrepairs]

Appreciate the videos Adam, still learning everyday and your videos are very helpful. Keep up the great work.

[@jamesrbrindle]

Awesome video Adam, looking forward to your video on graphics hardware, I was trying to explain line buffers and muxing to someone the other day and in my head I understood it cos I have my games to fix but man, explaining it was difficult. Keep up the great work.

[@pdrg]

Thank you, that was a really interesting session and well presented, right level of detail, and I love engineers sharing without ego like this. Please continue with your series :)

[@jamesv833]

Looks like this will be a great video series, I look forward to learning from your experience. Thank you

[@MichaelLloyd]

[@vintageclubjunkie]

This video was great! Can't wait for more brain-stretching episodes!

Brilliant!!! Any content is more than welcome =D

[@kristoferhanssonaspman3879]

Awesome! Looking forward to more episodes!

[@teeeeeeeeeet]

Excellent. Hopefully more coming. Great job

[@dinkyflix]

Awesome idea for a video series, Adam! By the way, I totally had that same Gravis gamepad way back in the Windows 95 days! -jimbodeanny

[@patanunaki4226]

Great vid!! I really like the way you explain stuff. Keep m coming please!!

[@MaximRecoil]

A couple of months ago the "left blow" button on my Super Punch-Out stopped working. After confirming there was nothing wrong with the microswitch and wiring, I looked at those same schematics you showed in your video, saw the 74LS240 at 1R, replaced it, and that fixed the problem. Here are the test results I got on the bad 74LS240 that I replaced: Logic Unit 1 Test Normal Logic Unit 2 Test Normal Logic Unit 3 Test Error Logic Unit 4 Test Normal Logic Unit 5 Test Normal Logic Unit 6 Test Normal Logic Unit 7 Test Normal Logic Unit 8 Test Error

[@RetroKonsol]

[@cbart1987]

Love the blooper reel at the end

[@utubepunk]

Thanks, Adam! Wish John have a whole video dedicated strictly to viewer mail.

[@racer4200]

Awesome, Adam!

[@AkebonoRadio]

Yes More, learning so much from your channel. Question: Do you have any recommendation to convert a vector monitor to LCD? I have a working 1983 Star Wars. With vector getting rare, would like to convert it...I know blasphemy.

[@chuck12-82]

Adam, will you take questions from Ron Phillips? ;-)

[@onecircuit]

+Chuck12 - Yes this week I will ONLY take questions from Ron Phillips. ;)

[@jonesandy911]

Yes, I did enjoy it !

[@fookutube501]

Bro so much love in here for you!!..Do more clip .it seem everyone has interest in you

[@macktastic22]

Adam, i have a pga tour, and the monitor has vertical collapse. Is this something i should try and fix? Local shops are charging 200+ to fix it. I dont know how to do it. Is it easy? Not sure what to do...... please help. Thanks

[@bobbyjack8033]

Nice. H3 buffer was the killer on my tempest board, btw whens pole position board going to be done ;) jk

[@jumpingeneral]

New to the channel. Great work !

[@EdwinNoorlander]

Adam, I really like this. Can you do something with FPGA. VHDL??

[@thefirstbrianmiller]

excellent

[@snooks5607]

at 26:54 use right-arrow key to skip 5sec, "supergun is a bu- plug". you're welcome.

[@sf98]

Hey Guysssssssssssssssssssssssssss we're at the Hanger.

[@Neffers_UK]

Yep this was cool. Not relevant to anything I'm doin or anything but still interesting non the less.

[@TimIskander]

Hey Adam... not to doubt your advice, but when I went looking around fro info on that Konami 005273, I found this thread (forums.arcade-museum.com/showthread.php?t=373344) and consensus is that the 257 goes bad more often than the resistor array. Also easy to source to check out... Either way, love these types of vids, :)

[@TheTimeRunners]

First!
