The Amiga graphics overlay with a Genlock had a very interesting purpose back in the 90s. There were people out there who would get copies of anime (usually via very expensive laserdiscs or even just tapes copied off of Japanese TV) and would use the Amiga to put fan subtitles on these and then output it to a VCR. It was incredibly manual and tedious work but once you had a master copy you were gold. The US (and in many ways global) anime market owes a lot to those nerdy bootleggers messing with Amigas in their college dorms.
I've thought about doing this exact thing with some of the anime laserdiscs I have and doing high quality hard subbed LDrips with my pc capture card lol
When I was at uni I used to watch these bootlegs in the '90s at a lecture theater on a Saturday night. These nights always sold out really quick, whereas the nights without the subtitles had empty seats! The humor of Japanese anime blew my mind and left me in hysterics! :-).
I appreciate you having time stamps on your videos. Even though it’ll all get eventually watched, when I’m just taking a 5 or 10 min break to “check emails” at work, having the time stamps is pivotal to seeing what drew me initially to the video quickly.
@@cubey The HDMI Output is much better than the Amber output. Modern HDMI flatscreen monitors have some problems with the old analog VGA flicker fixers (And Amber is one of those) The linear scaling mode is so awesome good, the picture is as sharp as in an Emulator and you can add variable scanlines if you want.
The performance of the shared video improves markedly with the addition of (1) fast RAM, and (2) a faster CPU. If you only have chip ram, the bus is contended with Agnus DMA requests coming from the main system, as well as the bridge card.
Very interesting. It was also nice to test and see frame by frame opening and closing windows (in your video) and see how it draws in hdmi (use . and , keys for frame by frame view in TH-cam player). Thanks for the video :)
It never ceases to amaze me with all the projects Raspberry Pi's can do nowadays, either with vintage hardware or (in my case) just having a nice modern retro station to be able to play all the old school video games from the past.
Nice video and very interesting, thanks. It's cool to see all the new hardware solutions people create for these classic machines! Back in the '90s I managed to get a Commodore 1960 Multisync monitor that let me use higher res screen modes with no flicker on my A1200. Wish I still had that...they seem very rare these days!
I got kind of a late start to the world of computing, my first computer being a Macintosh Performa 630CD so I missed out on all the cool hardware I've always been fascinated by from Sun, SGI and Amiga. Thanks for making these videos!
Great video as always Adrian. I seem to recall, back in the last days I had an Amiga, there was a very hacky monitor driver that I got off Aminet that let you drive a 1084s up to 640x480 with relatively low flicker in WB, but it would cost you like 9 pixels of vertical resolution, plus it would dim the display somewhat. It's what I used up until I sold my 1200 (which I wish I had back :/ ).
Makes me miss my last Amiga. A 1200 with a Blizzard 060, 32MB RAM, 2GB HD, 28k8 US Robotics modem, some highres monitor. That beast worked fine for surfing the internet. The processor melted the plastic lid on the bottom so I had to make a vent for it 😂... Keep up the good work!
Most LCD televisions will accept a 15Khz RGB signal, so you can use one of those as a monitor with an Amiga to SCART cable. The hardest part is the 23 pin D-Sub connector. Although a flicker fixer/scandoubler is the best option.
North American televisions do not have SCART, unfortunately. In the vintage computing and retrogaming circles we're pretty jealous of its ubiquity in Europe.
You're still dealing with a soft picture due to the digitizer and scaling -- plus pretty significant delay in the video pipeline as well -- but it definitely works.
I would move the header connector far to the right and rotate it 90 degrees, to line up raspberry pi hdmi socket with the amiga slot in the case. Then you could be able to plug the cable natively.
That is absolutely stunning to see. I have to try and get my Amiga 500 back from my friend, though to my sadness i left my 1084 monitor behind to be junked in my last move. But at least this will let me use my machine again!
I'm guessing the mode I used for Workbench must be AGA only, it's called DBLPAL and allows for progressive scan at 676x540(this, of course, with gratuitous use of overscan) at 50Hz by the RGB out. I currently use it plugged into a modern multi input LED TV via VGA cable, which can autodetect what I'm running and switch modes automatically. Back in the day I had to have dual screens, one a regular TV hooked up via RF if I wanted to play a game in regular PAL and the second a VGA monitor for using Workbench and productivity stuff.
Oh, yes, I well remember that interlace flicker… but I never got around to getting one of those flickerFixer boards, I think because they weren’t then available for the A500 or A1200.
The ICD Flicker Free Video board I have in the A2000 does work in the A500 too -- but it was probably a very expensive part. This project also has an internal board for the A500 and A1000 so if you still want to get HDMI, you can finally do it.
Maynard's was originally a UK company... they are probably best known as the inventors of Wine Gums. Charles Maynard was a teetotaller, and devised the sweets as an alternative to after-dinner drinks
The Amiga 3000 had a scan doubler built in so you could run a standard VGA monitor. It had a separate VGA port and a enable / disable switch. When you connected a VGA monitor to the Amiga 3000 you would set the switch to enable and it automatically scan doubled the slower signal to a signal compatible with VGA monitors
I so so wish all this modding was around when I began programming and tinkering with computers back in the 1980s .. omg people of today dont understand the stress it was trying and patience we had growing up with this tech compared to a mobile phone being more powerful than what we had back then lol
And definitely the Mac Classic, considering the Amiga was the much better Machine IMO. I never understood why Apple only had monochrome Video on a 16 Bit Machine.
@@nilswegner2881 Monochrome graphics were a lot less intensive to run apps on. People were still using Hercules/MDA PCs into the late 80s because they didn't need colours to do standard office work like word processing.
@@amirpourghoureiyan1637 mhh, funny how the Amiga still managed to be cheaper than Macs and PCs... With color graphics and awesome Sound already Out of the Box.
I had tons of sparkles on the original type adapters for my A500. After three (yes three!) from different vendors / makers claiming to use parts rated for better signal latch tolerances and trying small capacitors, etc I finally bought a LinuxJedi CPLD based RGBtoHDMI solution and I have only seen a sparkle once and even then I wasn't able to reproduce it. On all the boards the sparkles were highly dependent on specific color values and transitions as the sparkles are subpixel sizes.
13:25 - it's not perfectly clear what the sales distribution of Amigas were by model as there aren't records from all branches, but the German branch did keep full records and the A500 outsold everything else by a huge margin, so I'd say it's a safe assumption. Lines up with my personal experience: everybody I knew had an A500 or A500+A590, and only one family had an A2000, and only the high school had an A1000.
My A600 shares my PC Monitor (NEC Multisync LCD 1970NXp). Amiga on the VGA port, PC on the DVI port. The manual says it only does 31.5 to 81.1 kHz but it lies --- it does 15 kHz but some screens have 'Jail Bars'.
HDMI to VGA adapter. You're looking for an "active" adapter and a slight warning, active adapters are finicky. Some will work, some wont. I've had the most luck with StarTech.
Looks great on those displays. How does the Flixer Fixed scale to the native resolutions of the LCD to provide the most detailed resolution and crisp image ?
CSG 8372B or AB, a.k.a. "Enhanced Agnus", a.k.a. "Obese Agnus" (unoficial moniker ;-) ) is the name of the Address Generator IC you tried to recall ;-) It may also be a 8375, like the one I have in my A500+ which is also able to address 2 megs of chip RAM.
Well the Genlock feature was used extensively in video production. There were lots of animation studios doing animation on Amigas. The most famous one today is of course Dingo Pictures. At least in Germany getting a 15kHz CRT is incredibly simple, people just throw those out and any newer one will have an RGB input. The only problem, however, is that those are mostly low resolution ones.
I had a A2320 flicker fixer when I had an Amiga 2000. This A2320 never worked properly. Flashing pixel. Had a screw on the back to fix it but it never worked. 🥺
It is still missing the SPDIF input so that the sound can be combined with the HDMI signal, What about using an ASUS TECH EN9500GT which has VGA,DVI and HDMI and has a SPDIF input for feeding the Digital Audio into the HDMI signal.
@@trondmm Then there will be no sound on the HDMI that needs to be sorted possible installing a STEREO2SPDIF adapter so you get the SPDIF signal so that too can be send the HDMI cable via that Raspberry Pi HDMI adapter.
@@DAVIDGREGORYKERR As far as I know, the RGB2HDMI is a video only solution. If you want to include audio, you'll need additional adapters. It would have been nice to have audio support, but I don't think it's a priority.
@@trondmm if you are going to use the Bridge board that allows you to run 80586 code then the ASUS TECH EN9500GT actually has the SPDIF input but then you need to add a sound card into the Bridge board and the SPDIF can connect to the EN9500GT.
20:12 it could be due to the monitor itself but the hdmi seemed slightly faster or slower? Was it noticeable during use? Do you have any measurements about that latency? It could matter in games off. Thanks for the great video regardless this is really cool!
The most expensive part about putting one of these together would probably be the components. It's a lot more efficient to order (at least the basic stuff) in bulk, when I build keyboards I get enough parts to put together most of 4 or 5 for the price of ~2. Then again I only do that because it cost the same to order 5 pcb's as 1 on most places too, cheaper in bulk all around. If you're good at soldering (this project looks fairly straight forward, the smaller SMD stuff can take practice) a person could probably put together a few of them at the same time and sell the extras to easily cover the RasPi and parts.
regarding that hdmi to vga adapter, pretty much every one of those I've tried do not work with "smart" CRT monitors - that is the ones with an OSD and remember settings for different resolutions
Hmmm interesting. I haven't had that particular issue but on the other hand I haven't tried many adapters. I just have one that I use all the time and so far has never not worked correctly. (With LCD and CRTs)
@Adrian black: Which dos program do you use to revive old floppy / diskettes to image file? I have seen you have done in one of the videos. But dont know anymore it was.
I think this is a great project. Unfortunately, I have an Amiga 1000. I'm not sure there's enough room to fit the A500 solution inside the case, with the denise chip right up against the PSU.
I don't really think so -- once the OSSC has the right profile, it seems to work just as well. Only benefit would it would be all integrated inside :-)
@@adriansdigitalbasement Thanks. Any tips on applying the profile? I think you mentioned in one of your recent videos that you adjusted the phase to 90 degrees. Is there any more to it?
An OSSC should have lower latency than RGB2HDMI, so the only advantage would be convenience. And price of course; if you want to use more than one machine at a time.
The Chip that does the memory Management is called Agnus in OCS amigas Like the 2000 and 500 and the Upgrade you have on that 2000 introduces an ECS memory Controller that's called fat Agnus that would normally only be found on an A3000, an A500 plus or an A600. Although there are some exceptions Like in everything that has to do with Commodore...
Not quite accurate. Agnus was the ICS/OCS DIP package version of the Agnus. Fat Agnus was the OCS PLCC package version of the same chip introduced in the A500/A2000. It was functionally the same as Agnus, it was just in a square package (hence it looking "fat"). Later ECS versions of Agnus didn't really have a proper name but were often called "Fatter Agnus", "Obese Agnus" (for the 2M version), or "Super Agnus" colloquially. The ECS Agnus was mostly identical to classic Fat Agnus, but had the ability to access more memory, allowed arbitrary vertical refresh rates, and allowed larger blitter operations (the blitter didn't work any faster, but you could blit more with just one command -- nothing really used this feature until AGA, but you could theoretically reduce how often the CPU had to talk to the blitter and work in fastmem or cache instead).
@@nilswegner2881 Yup. DIP non-fat Agnus is getting pretty rare now since they were only released in the A1000, so there are adapter boards to take the very common OCS Fat Agnus and insert it into the A1000's regular Agnus socket.
Google that damn! it's depending of motherboard, google motherboard model, and find flasher for your motherboard, put on floppy disk with bios image, and boot from floppy,than flash bios, u need to turn off flash protection in bios before that. Every motherboard have specific flash program.
@@adriansdigitalbasement that's what I meant by "would First have to be modded". You'd need to Open the Machine Up and Install this Component Adapter board.
@@neophytealpha while that's true I don't quite See the Connection to this Threads topic in this information. Would that Vic 2 replacement have an RGB Output that one can just Connect a cable to or why did you Bring this Up?
When I seen Pixel Perfect, I was thinking about one of my old televisions. It’s an 52PFL7422D/37, it’s got it’s quarks, but it old. I was thinking that one/part of a board was modded to be used.
Yeah the Flicker fixer doesn't need to go into the 3000. The 3000 had its own flicker fixer built-in to the motherboard As for the 4000 ... it had a different chipset (AGA)... but incredibly, didn't have flicker fixer like the 3000. Guess they assumed people would get video cards with it already built in. Picasso IV video/graphics card for example. There were external... flicker fixers available too. they usually went in between the monitor and the pc on various ways... usually any video output and then the monitor(s) plugged into it. These alternatives were useful if one didn't want to open their machine... several types were made including one (can't remember the name) that actually gave a lot more modes and colors.
I loved my amiga 500, 600 and 1200 but i used them only for games. I used to like colelcting the Originals to play them OG style but i found WinUAE is my jam now.
Regarding the pixel dropping, sampling at 70ns instead of 35ns just means you lose the 35ns modes in ECS,, but it's a huge problem in AGA where games could use subpixel scrolling. There are games like Worms: Director's Cut where the display, while only being lores pixels, is actually effectively a 1280+ pixel wide display because the wider pixels are scrolled at finer increments than the pixels themselves. Sampling at a lower resolution effectively destroys the smooth scrolling.
What about the RGB hooked up to an HD TV with an RGB to SCART cable? I know it's not a monitor, but still cool, I use my Amiga 500 that way. Or SCART is not a thing in the US? I wanted to see some game running on it :(
SCART is not a USA thing! They mainly use/used composite, and component, and also S-Video in some instances. The SCART socket is a UK/European thing, and yes, it gives perfect RGB if used with the correct cables! :-)

Hmmm interesting. I haven't had that particular issue but on the other hand I haven't tried many adapters. I just have one that I use all the time and so far has never not worked correctly. (With LCD and CRTs)
That is so cool.
Hmmm, the hdmi to vga was a nice extra piece of info. That’s given me an idea 👍
@Adrian black: Which dos program do you use to revive old floppy / diskettes to image file? I have seen you have done in one of the videos. But dont know anymore it was.
I think this is a great project. Unfortunately, I have an Amiga 1000. I'm not sure there's enough room to fit the A500 solution inside the case, with the denise chip right up against the PSU.
What’s that small 4:3 screen? Does it say: Evovo?
I've been toying with the idea of getting the A500 version but I wonder if it has any benefits over using my OSSC?
I don't really think so -- once the OSSC has the right profile, it seems to work just as well. Only benefit would it would be all integrated inside :-)
@@adriansdigitalbasement Thanks. Any tips on applying the profile? I think you mentioned in one of your recent videos that you adjusted the phase to 90 degrees. Is there any more to it?
An OSSC should have lower latency than RGB2HDMI, so the only advantage would be convenience. And price of course; if you want to use more than one machine at a time.
5:42 glad you didn't give up...
The Chip that does the memory Management is called Agnus in OCS amigas Like the 2000 and 500 and the Upgrade you have on that 2000 introduces an ECS memory Controller that's called fat Agnus that would normally only be found on an A3000, an A500 plus or an A600. Although there are some exceptions Like in everything that has to do with Commodore...
Not quite accurate. Agnus was the ICS/OCS DIP package version of the Agnus. Fat Agnus was the OCS PLCC package version of the same chip introduced in the A500/A2000. It was functionally the same as Agnus, it was just in a square package (hence it looking "fat"). Later ECS versions of Agnus didn't really have a proper name but were often called "Fatter Agnus", "Obese Agnus" (for the 2M version), or "Super Agnus" colloquially. The ECS Agnus was mostly identical to classic Fat Agnus, but had the ability to access more memory, allowed arbitrary vertical refresh rates, and allowed larger blitter operations (the blitter didn't work any faster, but you could blit more with just one command -- nothing really used this feature until AGA, but you could theoretically reduce how often the CPU had to talk to the blitter and work in fastmem or cache instead).
@@NozomuYume I actually didn't know that but it makes a whole Lot of sense. Thanks for Clearing that Up.
@@nilswegner2881 Yup. DIP non-fat Agnus is getting pretty rare now since they were only released in the A1000, so there are adapter boards to take the very common OCS Fat Agnus and insert it into the A1000's regular Agnus socket.
@@NozomuYume interesting, I have to Open Up my two 500s again to refresh my memory.
This converter is very cool. But if I use a Raspberry pi I would wait for the Pistorm. I don't know when the Pistorm is available here in Germany.
Ye, maynards make wine gums in the UK. I was always jealous of hardware sprites on the Amiga, my Ataris didn't have them at first.
Is there any comparable solution for the A600 ?
Hi Adrian!
I want flash bios on a 386dx machine. Ami bios. Witch version of Ami flasher must i use? Please help!
Greetings from Hungary!
Google that damn! it's depending of motherboard, google motherboard model, and find flasher for your motherboard, put on floppy disk with bios image, and boot from floppy,than flash bios, u need to turn off flash protection in bios before that. Every motherboard have specific flash program.
I wonder whatever happened to my Amiga 1000. I don't really remember.
? ive got a brand new 250gb eide hard drive from western digital i was wondering if u had a use for it as i do not
12:58 I think you meant to type "artifacting"?
Do you repair Amigas I have a 2000 that will not turn on after my son pluged the external drive cable back into the machine making a loop.
Lol! in wich port he pluged in external drive cable? is that usb cable of that external drive?
I have a big as question can you run a Linux distro on an amiga I know ms-dos is sort of like Linux but can you run any kind of Linux distros
What about RGB to HDMI for the Commodore 64?
A Commodore 64 would First have to be modded to even Output any RGB Video. It only Supports S-Video in the Stock config.
@@nilswegner2881 There are already people working on a VIC2 replacement.
You can use the RGB2HDMI on the C64 but you first need the Component output board. See more here: th-cam.com/video/oo_gWjK-gGw/w-d-xo.html
@@adriansdigitalbasement that's what I meant by "would First have to be modded". You'd need to Open the Machine Up and Install this Component Adapter board.
@@neophytealpha while that's true I don't quite See the Connection to this Threads topic in this information. Would that Vic 2 replacement have an RGB Output that one can just Connect a cable to or why did you Bring this Up?
Ouch I just bought that Eyoyo LCD with bad firmware.
When I seen Pixel Perfect, I was thinking about one of my old televisions. It’s an 52PFL7422D/37, it’s got it’s quarks, but it old. I was thinking that one/part of a board was modded to be used.
I remember interlacing. It gave me a headache.
I love that PlanetX3 has become a de facto standard to show that "normal software runs"
PAL is 640 x 512; 640 x 480 is the PC-bucket.
I've got a Toaster, but haven't used it yet, it's really neat hardware though
Does the a1200 have an expansion port?
Yeah the Flicker fixer doesn't need to go into the 3000.
The 3000 had its own flicker fixer built-in to the motherboard
As for the 4000 ... it had a different chipset (AGA)... but incredibly, didn't have flicker fixer like the 3000.
Guess they assumed people would get video cards with it already built in.
Picasso IV video/graphics card for example.
There were external... flicker fixers available too. they usually went in between the monitor and the pc on various ways... usually any video output and then the monitor(s) plugged into it.
These alternatives were useful if one didn't want to open their machine... several types were made including one (can't remember the name) that actually gave a lot more modes and colors.
I loved my amiga 500, 600 and 1200 but i used them only for games. I used to like colelcting the Originals to play them OG style but i found WinUAE is my jam now.
nice old amiga
Would something like that work on an Amiga 1200? Id love to hook mine up to a modern LCD monitor via HDMI :D
Perhaps the Amiga 600 version works on the 1200. Check Jan Beta.

Isn't it weird how the computer that is digitizing and converting the graphics has more capability than the computer it's connected to?
Will it work for the C128?!
Regarding the pixel dropping, sampling at 70ns instead of 35ns just means you lose the 35ns modes in ECS,, but it's a huge problem in AGA where games could use subpixel scrolling. There are games like Worms: Director's Cut where the display, while only being lores pixels, is actually effectively a 1280+ pixel wide display because the wider pixels are scrolled at finer increments than the pixels themselves. Sampling at a lower resolution effectively destroys the smooth scrolling.
Wooooooow just freaking awesome DID YOU SAY IT WORKS WITH THE A500
Yes, it is an internal mod. (well, the hdmi cable needs to come out somewhere. Perifractic / Retro Recipies has a video on it)
There is a A1000 version now it seems
What about the RGB hooked up to an HD TV with an RGB to SCART cable? I know it's not a monitor, but still cool, I use my Amiga 500 that way. Or SCART is not a thing in the US?
I wanted to see some game running on it :(
SCART is not a USA thing! They mainly use/used composite, and component, and also S-Video in some instances.
The SCART socket is a UK/European thing, and yes, it gives perfect RGB if used with the correct cables! :-)
I just want to say that using edibles as packaging fluff is an amazing idea.
