While I enjoy watching these videos and how excited ppl get from them, I just don't get why ppl want to play these very basic games when there's amazing games with stunning graphics out there! But each to our own....
Daniël Mantione (4 days ago)
I enjoy both modern PC games and playing on my Commodore 64. Both are fun, but it is a very different experience. Different input devices, different games, different monitors. So it's not that the PC is a replacement for the C64 just because it has stunning graphics.

Question: I see your VGA monitor can't display a signal at NTSC frequencies (15kHz, I believe). I know that many years ago (late 80's), Multisync monitors could sync that low. Do you know of any sold today that can? I ask because I'm concerned about when my Apple IIGS monitor dies. The RGB output from a IIGS is effectively VGA compatible (at least in terms of voltage levels) but it uses NTSC sync frequencies, making it incompatible with any VGA monitor I've got. I know that TVs can sync that low, because that's the frequency used by SD video (digital as well as NTSC). Does anyone know if you can get a TV with a VGA input that can sync to 15kHz and therefore display an RGB signal from an old computer? I suppose I could hack a TV like you did, but I get very nervous working around high voltage parts like a picture tube or flyback transformer, so I'd prefer an alternate solution, if possible.
Daniël Mantione (4 days ago)
Well, it used to be that PC monitors could not handle 15 KHz signals, but it is getting better because of the spread of HDMI. There exist HDMI devices that output 15KHz and 50Hz (in fact support for them is mandatory for compliance with the standard) and therefore both start to be supported by monitors in order to increase compatibility. Carefully check the specsheets, you can find what you need. Another approach could be to simply buy a TV. A TV needs to be able to display 15KHz content, so always supports it. Using simple dump VGA to HDMI converter can get you a RGB input on such a TV. Another approach is a SCART to HDMI converter, but these devices are often intelligent and do stuff like scaling and de-interlacing.

But will it play Doom of Wolfenstein?
Daniël Mantione (4 days ago)
For both of those games, source code is available. So even if they don't run properly, you could easily fix them.
Phino K.M. (13 days ago)
Or you could have just connected the wire coming from your switch to the other side of the resistor. I would expect 7.2k Ohms to be enough to limit the current to a healthy amount for the micro controller to sink. At 5 V that would be less than 1 mAh. One should of course make sure whatever is behind the resistor can tolerate 5V without a resistor in between and if not add a 2nd resistor in series with the 7.2k Ohm resistor and connect the switch in between the two resistors.

COol! Videos. Is there a 16 bit issue with Big ENdian Vs Little ENdian. Im not sure but I think its an 8bit rotation. Can you possible take 4 tv signals and smush them into a tv either 2 steroscopic MONO or 3 videos 1/4 screen used for audio signal and left and right plugs used for mono videos. To make a steroscopic channel or 3 tv channel switch from 1 broadcasted channel. openInvent.club I want to help contact me. I want to learn stuff. links to resources in your video descriptions please.

what dirty hack could you come up with that lets RGB work on a VGA port without having to buy a converter box? (again, dirty hack, using maybe some caps, resistors etc from the spare parts drawer) this of course, skipping a "line doubler", which is why I'm curious to see the output!!! :)

Can you explain something about YouTube video formats (I think this has to do with codec). I noticed sometimes on YouTube a video will pause for whatever reason and the audio keeps going. Then all of a sudden the video will forward and catch up to the audio. Is this by design in the codec used or is something else going on here? It seems like in any other video device if video stops the audio stops.

Hey 8 Bit guy! I love your restoration videos! I've been trying to get into vintage computers myself, so I was looking up older computers on eBay and saw this. If you can, you should get it and try to restore it.

It will be easier just to add a rectifying diode so that the 5v don't go to a chip. Switching the pin out of a chip directly introduces noise to it. Not good.

In 1996 scientists decided that human exploration of Mars was necessary. One man would go, but none would return. They needed a true hero, a man with nothing to lose. A man who has everything. Can do anything. Can be anything. so they chose The World's Fattest Man. In order to give the worlds fattest man true courage, the US government paid 1 Billion Dollars to any and all sexy celebrity women who would sleep with the world's fattest man. Once sexing all the women of his dreams, the world's fattest man (henceforth referred to as the worlds fattest man or 1tonstramrolleverything) had nothing to lose. He then, of course, agreed to go on a One Man Suicide Mission to Mars. To Save Us All. The Rocket that carried 1tonsteamrolleverything to his destination was the B-128-22--1-n!. Shaped like a coconut crab, and sprayed top down with internet memes, the craft was deemed invincible. Inside The Craft the worlds fattest man would ride around is in Rascall, or simply SteamRoll in small spurts to get around, eat, or sex the many many women provided by the holodeck. Upon landing, 1tonsteamrolleverything looked up at the Sun and began his long trek to the top of Olympus Mons. The entire world watched him, we laughed, cried, and Anne Hathaway said that she would never ware underware again in his honor. eventually the worlds fattest man reached his destination. NASA said, "OK 1ton, it's time to do your thing, good luck and godspeed" He said "STEEEAAAMMMMROOOOLLLLLL EVVVVEEERRYYYYTHIINNGG!!!" Then he bit down on all the yummy cyanide pills he could, detonated the Nuke, and SteamRolled. He rolled on and on and on and on and saved us all. And so everyone on Earth got attractive and then got liad. And freedom and food and drugs populated the world. and Rainbows, everywhere. The Universe was conqured much sooner than thought as a result. The govt made catgirls and everyone liked that too. Thank you sexy celebrity women Thank you worlds fattest man. One day we to will learn to SteamRoll, perhaps on Earth too. We will teach our children, and our childrens children what ne can really do the second they hit 1 Ton. One day to save us all Once again?

In the 90s, the general idea was that it would be too much trouble to rgb mod a TV for consoles or arcade games/older computers Thank you for confirming this! However, the results are amazing except at some point certain pixel art just looks a little flat without the signal artifacts.

It's 2020.....The 8-Bit Guy hasn't been seen in months, except for in the form of near daily half hour long unboxing videos. His house is now completely full of "Old Commodore Stuff", the walls no longer visible, the floor now a narrow path between towers of non functioning 80s computers and collumns of floppy disk drives. His wife and kids serve almost exclusively to go to pick up new packages from the post office. He sleeps on a pile of bubble wrap just out of view of the camera, all of his waking hours consumed by opening packages. This is his future.

Hey Dave I wanted to email a question to you but couldn't figure out how to do that.. I was wondering if you would consider taking on the challenge of figuring out how to run Tandy 1000 HX files saved on 3.5 on a modern Microsoft PC.. I have some old symphony files created with my Tandy back in the day and would love to be able to run them on my modern computer. I don't think file formats are compatible without some work.. I could swear When I upgraded to and old IBM back then (PS2) that Tandy files would run perfectly.. Anyway if you decide to do this I would be quite happy.. I don't like emulators  either lol.. I did buy older DOS versions and installed on my lab pc and had no success..

TheCrakkle (24 days ago)
I would also add a resistor in line with the 5V supply to the switch. This will also save the "Jungle" chip's input from being held "Hard On" this eventually may cause failure of the Jungle IC. Though myself I would have installed a 1N4148 Diode in line with the resistor on the Micro Con't side. Then just connect the switch wire to the point the resistor and diode connect. Simple and mo need alter the switch.

jcilley97 (25 days ago)
The 8-Bit Guy I believe if you modified a tbc or time based corrector or macrovision defeat device, aka a digital video stabilizer to use analog rgb and vga I guess that should fix the problem, idk, I have never had experience doing that. So you can give that a try. Ik a lot of times digital video stabilizers were used to circumvent macrovision on vhs tapes, which if you are interested in, hacking one of those for your personal use, you can probably get clear macrovision defeated signals on rgb and you can transfer all of your store bought vhs, beta, etc tapes to DVDs for personal use. Also have you ever thought about modifying a digital tv converter box to use rgb to pick up digital ota tv signals on an analog tv? I am pretty sure if you are not messing with the rf in or rf out’s antenna field strength while doing that, you should be okay I think? Those are just some suggestions.

Wow, that reminded me trying to hook up my Amstrad Mega PC to the same kind of TV about 10 years ago, with simiar caveats (execept it was much easier for me because I'm in a SCART-heavy land). I always wondered why some 320x200 EGA games would not fill the screen, even though I used different TSR programs. Also this solution is not very good for demos, as most of them access the card directly. I challenge anyone into trying to run Crystal Dream II in 15KHz without cheating by using extra hardware. Note for the curious who want to know about the Mega Drive part of the Mega PC. Indeed it will work with a TV, but you won't get a picture by combining the syncs passively. You'll either need to build Tomi Engdahl's circuit or buy yourself a UMSA adapter. Also, the Mega Drive part is very iffy when used with scalers and some multisync monitors as the vertical sync pulse sent by the Mega Drive card may be longer than it should.

rootbeer666 (26 days ago)
Well, duh. Also, I have a concern regarding the RGB lines where if you activate OSD you may have output drivers of the OSD chip and output drivers of your console fighting. I learned that mistake of running two output drivers into the same line (assuming I was doing a "wired OR") and cooking some 7400 series chips in the process back in college. I would also put OSD chip's output enable pin onto the switch if it has one, that way when you've switched your RGB mod on the OSD chip will not be activating output drivers... that is, if it has such a pin and the chip is tri-state. Otherwise cut power to the OSD chip with the switch.
Daniël Mantione (26 days ago)
You are right, but since there are resistors in the system, we are probably speaking of a few miliamperes that won't cause a lot of trouble. If you are purist you could try to fix this, but generally a few miliamperes will not damage electronics.

So I know based on what you've said in your videos that you think it would be boring for the viewers if you walked through the coding process; you've done it in tidbits but I am really curious to see a proper walk-through of how you design, code and create content on these old 8 bit systems--how you make the art and how things are implemented. It would be very intriguing to the coding crowd.

John Smith (27 days ago)
If you ever do this again you should use a VGA connector on the TV. It's smaller and more convenient then using RCAs. Also VGA has +5 volts on pin 9 that you could hook up to a relay that automatically switches the blanking on the jungle chip. This way just plugging in a VGA source will switch the TV into RGB mode and unplugging it switches it back.

It is possible to add pots to adjust the image size and position (with the right know-how). The main reason to do this mod is to play old arcade game emulators in native res and they came in a variety of obscure resolutions. I use the pots on my arcade monitor to adjust the image for every game change...
Thibaut Allender (27 days ago)
You can do that in Windows using CRT_EmuDriver and specific cards. That's well known in the emulation scene when you want to use an original arcade monitor, or, like here, a cheap TV that accepts RGB.

I don't think he'd care too much if it was almost 30 years since he made it. Also, no money goes to the creator when used games are purchased. I don't think it makes any difference if you get something on ebay, or the Pirate Bay, the creator doesn't get the money either way.
