When I was a kid, my dad fixed our TV antenna with a bit of plasticine, "just for now". That temporary fix lasted few good years until the antenna broke completely.
Seems like David know nothing of the Intelli. Otherwise he would be floored. I myself was stunned. Those guys didn't push the Intelli to it's limits. They went past!
Looks incredible and the music sounds amazingly faithful too. I'd like to see a version for the Vic 20, but the lack of hardware sprites would probably make it less playable and attractive than the Intellivsions version which seems to play and look almost exactly like a low res version of the brilliant C64 version.
I begged my parents for an intellivision and never got one. They said my Atari 2600 was good enough. I begged my parents for an NES and never got one. Our 2600 was good enough. So I gave up on consoles and went into PC gaming because my parents had no problems upgrading my computers when ever I asked. After all my PC was "educational" lmao
I never had a console or bedroom TV. My parents got me a cheap Compaq desktop in 1999 for my birthday and dialup internet. I saved up every summer and extensively upgraded it over the years to play newer games. I learned how a computer fundamentally works and how to manually repair broken parts. I threw in the towel and gave up last year when I just couldn’t get it to run Office 2019. It runs everything else just fine-Windows 7 games up until around 2013. I bought a new old stock MacBook Air that still has serviceable parts and it’s really nice to take with me to work and in the garage. I keep that old computer under my TV for streaming web radio and playing retro games.
Those2menoverthere . Thanks. If it weren’t for my parents making me learn how to understand and take care of my things, I’d be a completely different person nowadays. Same goes for my truck and my other little things. I love that old Compaq and I’ll keep it forever.
My husband introduced me to your videos a while back and have been hooked ever since. I love watching you fix and clean things up. Watching you modify computers and such is pretty dang cool. Congrats on the million! 🥇🎉🎉🎉🎉🎉🎈🎈
The passive RLC termination on the output of the video chip, and new additional composite circuit, has to keep the vertical and horizontal video blanking pulses clamped at a constant level for the TV to properly lock to it. Additionally, on the _back porch_ there will be the colour-burst that needs to be stable for a good locked chroma. Just above that is the black reference level that also must stay constant to maintain a constant brightness for the entire frame. This will take a bit of experimenting to get right and I imagine may be more complicated than just a resistor. Cheers,
According to the circuit at 4:36, the signal is only AC coupled... So when you remove the RF modulator, I suspect : - either a problem of DC bias of the previous stage. - or of input impedance. To get the same DC bias: 1- Measure the DC voltage value on the signal input when the RF modulator is present. 2- Replace the RF modulator with your circuit. 3- Add a big valued potentiometer between +5v and Gnd and connect the mid point to the your circuit input. 4- Turn the potentiometer until you measure the same DC voltage as in 1. To change the impedance, try as above with different valued potentiometers. (Or less experimentally: Ohm's law would give you R=R1//R2 if R1 and R2 are the two parts of the potentiometer). I hope this helps. Good luck!
The output impedance of a video circuit must be in series. The TV's input is in parallel to ground, so that its input is halved from your output. This guy's simple passthrough amplifier circuit shows the difference between input and output: www.labguysworld.com/VideoCookBook_002.htm
I always click on these videos thinking i'm just going to listen to the intro music and move on. Next thing you know its been 3 hours and on a separate tab i'm looking up the cost of a Commodore 64.
A lot of my life was spent playing Defender of the Crown on my Amiga 2000. Thanks for a fun and very useful mod on that Intelevision. It's absolutely something you can retrofix later and tweak.
This was amazing. The first console I ever played was the Intellivision and it's always great to see that fun system preserved and modernized so it can still be enjoyed. Sub +1 :)
I remember my dad had his original-model Intellivision composite modded by one of his engineering friends. He just brought it over, his friend had the board already made up, and in 5 minutes he'd opened it up, mounted it, drilled the holes, and it works fine to this day. That said, I've never opened it up myself to see *how* they did it.
Huge congratulations to David, the 8-Bit Guy for getting over a million subscribers! I watch the David's videos because they are so precise about every detail. Fascinating!
Except it probably wouldn't have because they're no doubt leveraging a large amount of ROM space (and probably extra components for bank switching) to make it look that good. Its doubtful even near the end of life of the console that they could have released it without having to charge an exorbitant amount of money for the game compared to normal game prices for the system.
@@JeremyLevi So when you consider the Starpath Supercharger cost $69 at the time and it had 6KB of RAM, they likely could have done a 50% upsale and still sold like gang busters.
@@WildkatPhoto Sure, but consider the Commodore 64 version (roughly comparable in quality) is over 160KB in size ... assume you're probably looking at something like 64KB-128KB of ROM, minimum, to fit the game. That's not small potatoes, cost wise in '86 (and not even thinkable in '79 when most cartridge games used 2-4KB of ROM).

"It runs the same games". Well, almost all of them. Mattel modified the Intellivision II BIOS so that it would not run third party games like Donkey Kong. If you look at some game boxes they will have a sticker that says "Not for use with Intellivision II".
ONE MILLION SUBS!!! You deserve every single one! I love this channel, and have already learned SO much from watching your videos. Hope you have a nice trip out of town! Be safe!
Most certainly, but I wasn't able to work it out. The mod that everyone is using is based on the load the RF modulator is drawing and modifying it is not as trivial as I thought. Long story short, we just don't have the time to work on it more at the moment. :-)
My first thought was that the modulator needed to present a 75-ohm load on the video signal. But as you say it sounds more like something else. That looks like a standard Astec RF modulator from that era, so opening one up to see what's inside should help. I understand it takes time and effort to do that; don't worry, we're enjoying the journey to get there! ☺👍 [ Edit ] If this helps, a link to a PDF doc with details: console5.com/techwiki/images/2/21/Astec_UM-1285-8.pdf Good luck!
@TexElec Sorry for suggesting obvious things, but have you tried just sticking potentiometer between video-in and ground, and another between audio-in and ground and just fumbling with those? If 75R resistor didn't work, try a pot - trust me, it's worth trying. You can also try to dig up a datasheet/schematic of a similar RF modulator - they are probably designed to be more or less interchangeable - and see what its inputs are supposed to be. A datasheet for console's videochip (if it exists) could also be of use. Measuring current/voltage with a multimeter is useless here, you need to get a datasheet and/or just guess the value. If you can find nothing, it is probably around 50-75 ohms, so start with a 150 ohm pot and slowly move it down. If nothing is overheating then it's most likely ok - just don't leave it powered for more than a few seconds. If possible, hook a scope to the line while moving the pot. I'm sure you'll see what's going on. If that didn't work, I'd try a stupid thing - connect the modulator to the video output through another pot and slowly move it up until picture starts deteriorating, then attempt to counter this with pot to ground, and repeat. Another thing to try is modify the new amplification circuit - hook up pots instead of resistors and look at the scope, comparing with how it should look like with modulator attached. Probably combine with previous method That being said, I still don't understand why remove the thing in the first place? Isn't having two output options better than one? I don't think signal quality suffers all that much from an attached RF modulator - it's most likely not that great to begin with, crispy clear consumer TVs did not really exist back then so I doubt anyone put too much thought there.
@@jwhite5008 I had about 4 of them going, and just could never get it to look 100% correct on the scope. I tried tacking on several loading caps / resistors of various values, etc. The fact is, video signals are fairly picky. I was able to get unstable images, but never really as refined as the original circuit. I'm working on a ton of stuff right now, including the X16 and there are a ton of INTV mods out there just like the one I built on the perf board for $20 or so. I was hoping to replace the modulator as I personally always remove them to prevent interference, but honestly, I think an FPGA->HDMI approach would be better so I don't even know how much more time I would spend here.
@@TexElec Analog video signals and RF in general feel a bit like voodoo at times don't they? There are fully documented specs and waveforms for NTSC timing out there, but modeling high frequency circuits and working out precise timing with passive components is an unforgiving art. Especially when you consider the host devices are tuned and tweaked as assemblies based on the inductance, capacitance/impedance/reactance of the all the components in the signal chain from the power supply to the casement. The most reliable way to do it today is as you suggest, put an ADC at the video chip's output and generate the right signals using modern electronics with some isolation from the dodgy retro circuits.
Why didn't you wait to figure out the issue with the RF Module before drilling holes into your console? Wouldn't it have been better to just put the wires through the back vents for the time being before drilling holes you cannot undo? Not criticizing I'm just wondering why you went this route.
Because it's an intellivision II so he's not worried cause he's keeping it for himself. You wouldn't do that to an original Intellivision due to value issues. Though to be honest they don't command high prices even though they were better than Atari's.
Hover Bovver actually makes use of the Intellivoice. The voices add to the game's humor. Also, the original Intellivision has a way better controller than the Intellivision II. I have one of the only Intellivision composite mod videos on youtube, so you might have watched mine :) Cool to see some Intellivision love on your channel even though it wasn't your jam back in the day.
I don't know if you are familiar with the British Sinclair ZX Spectrum 8-bit home computer, but once, many moons ago, someone wrote a game for that machine called Lawn Mower Simulator, which was so primitive that it sparked an annual Crap Games Competition. Ironically, some of the entries have been surprisingly un-crappy. ;)
Thanks for posting this. I've had this mid sitting around waiting to be installed. You motivated me to dig out my I2 and install it. It looks so much better. It also works with the 2600 add on plugged in. Thanks for the motivation and great videos!
Super happy to see the Intellivision getting some love, especially the II that I had when growing up. I always die a little inside when I see old plastic being cut up, though. Hah
the modulator on the intellivision has parts inside of it that help create the composite signal so it has to stay or you wont get any composite out at all.
I don't know if this is a recent development but congrats on making 1 million subs! I love your videos they are fun and educational and I know I've learned a few things that have helped me over the last few years.
David, when we met and were on the way to the auto show together, you were at just under 400,000 subscribers. I said it was gonna keep going and you were like, "Nahhhh it's slowing down and I don't think very many more people are interested in this kind of stuff." Now look! I knew you'd get there. Congrats on the million.
Can't say I've ever heard the term "Christmas Tree bit" but I can see where the name comes from.... Those are very very handy though. I call it a "stepper bit" or just "step bit"...
Congratulations on more than a million subscribers and while I wasn't a huge Intellivision fan either, I admin, that Defender of the Crown look amazing, if you keep in mind what this system is capable of.
Noise, in analog video and television, is a random dot pixel pattern of static displayed when no transmission signal is obtained by the antenna receiver of television sets and other display devices. The random pattern superimposed on the picture, visible as a random flicker of "dots" or "snow", is the result of electronic noise and radiated electromagnetic noise accidentally picked up by the antenna. This effect is most commonly seen with analog TV sets or blank VHS tapes. There are many sources of electromagnetic noise which cause the characteristic display patterns of static. Atmospheric sources of noise are the most ubiquitous, and include electromagnetic signals prompted by cosmic microwave background radiation,[1] or more localized radio wave noise from nearby electronic devices.[2]
Oh man I had completely forgotten about Defender of the Crown. I don't know how many hours me and my best friend spent jousting on his C64 back in the day. Great memories, thanks!
Great video, David! Congratulations on 1 Million Subs! You should do something special. Like maybe a Livestream and play some of your favorite Retro games.
You did a grave disservice to Defender of the Crown. One of the most ground breaking titles in history, and you didn't even stay quiet long enough to hear the iconic opening score.
This is the retro hacking version of putting the working TV on top of the broken TV. But, seriously, I think it was a fine approach. The RF modulator is providing the 75 Ohm termination. I believe.
Those new Intellivision games look absolutely INSANE for a 1979 home console, very similar to NES games, and that came out in '85! Imagine Crysis coming out in 2001!
Getting better pictures out of old computers is always a fun challenge, I recently used an Amiga A520 RF adaptor to gut & use the DB23 connector to connect a SCART cable (Smug Mode Enabled) to connect my A600 up to my TV, and the picture quality over Composite is absolutely amazing on my LCDTV... :D I put all the wiring back inside the shell of the A520 so it looks sort of original, aside from the big black cable poking out the back where the RF connector used to be and the audio wires sticking out through the "Audio In" hole... :P
RF modulator being absent is probably causing an increase in voltage in the video circuit, a bunch of appropriate sized resistors on the RF power rail will probably pull the voltage/current down to usable level
The channel selector circuit may be part of the issue why it will not work without the RF modulator. It's been a long time since I worked with RF modulation, but I specifically remember the frequency changes being an issue.

According to the circuit at 4:36, the signal is only AC coupled...
So when you remove the RF modulator, I suspect :
- either a problem of DC bias of the previous stage.
- or of input impedance.
To get the same DC bias:
1- Measure the DC voltage value on the signal input when the RF modulator is present.
2- Replace the RF modulator with your circuit.
3- Add a big valued potentiometer between +5v and Gnd and connect the mid point to the your circuit input.
4- Turn the potentiometer until you measure the same DC voltage as in 1.
To change the impedance, try as above with different valued potentiometers. (Or less experimentally: Ohm's law would give you R=R1//R2 if R1 and R2 are the two parts of the potentiometer).
I hope this helps. Good luck!

hernanc wait this video was made half an hour ago wtf.
I am 11 years old and I have watched every single video and I think the 8-bit guy should keep up the good work
I wasn’t a fan of the thumb pads either, I ended up getting joystick inserts that replaced the disk, it worked much better.
Congratulations on 1 Million Subscribers!!!
Possibly you just need to terminate the signal. as @Leumas Saugi recommended.
Removing the rfModulater probably left the reference ground floating
Congratulations on one million subscribers David! You really deserve it, your channel is amazing.
"Back to the Future" clip?...... I see what you did there ;)
Super happy to see the Intellivision getting some love, especially the II that I had when growing up. I always die a little inside when I see old plastic being cut up, though. Hah
FYI, the "christmas tree bit" is called a step drill. :)
Wowowowoowww!!! 1 million subscription!!! Congrads!!!
I come here not to learn electronics but to refresh my childhood memories
Every time
Well you got two for the price of one!
Congrats on 1 Million Subs!
YOOOO 1 MILLION SUBS. CONGRATS DAVID!
Still the best video intro on youtube
Congrats on one million subscribers! Great video as always!
the modulator on the intellivision has parts inside of it that help create the composite signal so it has to stay or you wont get any composite out at all.
I see 8-bit Guy, I drop everything and click.
not always, but true
Congrats on reaching 1M subs David Murray!
This looks like an sync issue probably the rf modulator is responsible for syinc idk
I don't know if this is a recent development but congrats on making 1 million subs! I love your videos they are fun and educational and I know I've learned a few things that have helped me over the last few years.
I liked the background music in this episode!
Congrats on 1 million subscribers!
lol... I Swear he said Defender of the Crayon..... *clean ears*... *rewatch* "ohhhhhhh crown" lol
In a Southern accent, “crown” does sound like the Midwestern pronunciation of “crayon”. Southerners pronounce “crayon” like “rayon”.
Well, he *is* from Texas. ;p
Friendly Neighborhood Jesus Freak That’s my point exactly.
Yeah baby! One freaking million subs! It's play button time!
I always keep the RF modulator to use the console with the old TVs and just add AV mod for modern TVs ,so I can choose what to use :)
You made my morning better
David, when we met and were on the way to the auto show together, you were at just under 400,000 subscribers. I said it was gonna keep going and you were like, "Nahhhh it's slowing down and I don't think very many more people are interested in this kind of stuff." Now look! I knew you'd get there. Congrats on the million.
Can't say I've ever heard the term "Christmas Tree bit" but I can see where the name comes from.... Those are very very handy though. I call it a "stepper bit" or just "step bit"...
Congratulations on 1 million, bud!
One million subs! Been here since the iBook Guy videos!
Congrats on a million David!
Finally I have finshed homeworks and I can relax with an 8-Bit Guy video.
Thanks!
1 million subscribers congrats David
It's weird to see how much time and care you spend restoring and preserving vintage electronics.
Then you go modding and "destroying" others.
The RF modulator has the vertical blanking signal, the signal that tels the TV to start the fields ( 2 fields per frame) from top to bottom.
If you look in the black areas you'll see high crime and fatherless homes.
The modulator is almost all ground so think rectification. Also, Christmas tree bit? Unibit brother. Love your channel
That sweet high pitched sound from the tube tv can be heard on the video :)
Congratulations on more than a million subscribers and while I wasn't a huge Intellivision fan either, I admin, that Defender of the Crown look amazing, if you keep in mind what this system is capable of.
Noise, in analog video and television, is a random dot pixel pattern of static displayed when no transmission signal is obtained by the antenna receiver of television sets and other display devices. The random pattern superimposed on the picture, visible as a random flicker of "dots" or "snow", is the result of electronic noise and radiated electromagnetic noise accidentally picked up by the antenna. This effect is most commonly seen with analog TV sets or blank VHS tapes.
There are many sources of electromagnetic noise which cause the characteristic display patterns of static. Atmospheric sources of noise are the most ubiquitous, and include electromagnetic signals prompted by cosmic microwave background radiation,[1] or more localized radio wave noise from nearby electronic devices.[2]
Oh man I had completely forgotten about Defender of the Crown. I don't know how many hours me and my best friend spent jousting on his C64 back in the day. Great memories, thanks!
ONE MILLION SUBS! CONGRATS!
A new episode of yours and now the new Sonic trailer, this is gonna be a good day
Great video, David! Congratulations on 1 Million Subs! You should do something special. Like maybe a Livestream and play some of your favorite Retro games.
Congrats on a million!
What the heck was that outtro music... I need this in my life!
Congrats to 1 mil!!!
You did a grave disservice to Defender of the Crown. One of the most ground breaking titles in history, and you didn't even stay quiet long enough to hear the iconic opening score.
t8bg: i wouldn't need this anymore
20 years later: yes, i don't need it
Congratulations finally reach one million subs !
This is the retro hacking version of putting the working TV on top of the broken TV. But, seriously, I think it was a fine approach. The RF modulator is providing the 75 Ohm termination. I believe.
The 8-Bit Guy need a loading resistor on the Video signal line where the RF modulator used to be
Those new Intellivision games look absolutely INSANE for a 1979 home console, very similar to NES games, and that came out in '85! Imagine Crysis coming out in 2001!
Getting better pictures out of old computers is always a fun challenge, I recently used an Amiga A520 RF adaptor to gut & use the DB23 connector to connect a SCART cable (Smug Mode Enabled) to connect my A600 up to my TV, and the picture quality over Composite is absolutely amazing on my LCDTV... :D
I put all the wiring back inside the shell of the A520 so it looks sort of original, aside from the big black cable poking out the back where the RF connector used to be and the audio wires sticking out through the "Audio In" hole... :P
I agree with the last comment. You probably need a 75 ohm resistor between the video out on the board and ground :)
RF modulator being absent is probably causing an increase in voltage in the video circuit, a bunch of appropriate sized resistors on the RF power rail will probably pull the voltage/current down to usable level
A joy to watch, as usual.
The channel selector circuit may be part of the issue why it will not work without the RF modulator. It's been a long time since I worked with RF modulation, but I specifically remember the frequency changes being an issue.
