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 knew where this was going from how it started but I’m so happy that 90s VHS anime bootlegs used Amiga for subtitles haha
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
I had quite a few genloc fansub anime taken from laserdisc back in the day.
I know people who did this, back in VTAS. ^_^
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! :-).
Loved my Amiga back in the day. I have to recognize the genius of Jay miner whenever Amiga or Commodore comes up...
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.
You're having such a love/hate relationship with that little monitor. LOL
Very informative video. BTW, Amiga 3000 has flicker-fixer built-in (“Amber” chip), as well as coming with ECS and 2M chip ram.
Yep. I have a 3000 tower and it has a factory VGA port.
@@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.
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 CZcams 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.
Appreciate all your hard work creating these videos.
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.
Something tells me that a 32-bit AMD Ryzen 9 5950X overclocked to 4.9 GHz with 4 GB of DDR4-3200 RAM would be _too_ fast...
Every time the intro music starts my foot begins tapping along! ;-)
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!
This channel is basically Xanax without a prescription.
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 :/ ).
As Adrian showcases the candy, "I Want Candy" by MC Chris or Bow Wow Wow playing in the background. I couldn't resist...
Interesting explanation, thank you for sharing.
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!
Sure wish I had one of the hdmi converters a few years ago. What a great project!
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
Well hello Adrian and thank you for inviting me to your basement for another informative and interesting video 😀
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!
I love the Save / Use buttons on Amiga OS.
That's super cool, man I need to get some amigas in!
Gee and I was blown away as a kid on how good the coco 3 look with a rgb monitor.
nice old amiga
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
Great videos.
I honestly can't wait for the Amiga mini
Ironic that you could also probably just use that Pi Zero to emulate the entire Amiga
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.
@@nilswegner2881 And don't forget how crazy expensive a little RAM was back then.
@@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.
@@nilswegner2881 didn't stop them failing in the US, the ST was rubbish but still got better market share in the states.
I got the Amiga 1200 with an Indivision AGA Mk3 scanline doubler. Granted, it was expensive, but looks extremely crisp on my 50" TV.
Hai ragione,il segnale video dell'A2000 in HDMI e' perfetto,gran computer.ottimo lavoro adrian
I ran a computer bulletin board (BBS) using the bridge card on an Amiga 2000 for several years. I believe it was running BBS-PC.
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 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.
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.
5:42 glad you didn't give up...
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.
awesome video.. nothing like seeing success.. yeesss....
Adrian's definition of a very fast PC: Anything above 4.77mhz :) Have fun!
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.
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!
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 ?
There was the A500, that I also had, as well as A1200 before migrating to PC
Hmmm, the hdmi to vga was a nice extra piece of info. That’s given me an idea 👍
Without the internet, I would’ve assume the Amiga was a long dead PC that was nothing more than a footnote
Oh how wrong that is! What a beautiful machine the Amiga was... So unbelievably superior to a PC of the same generation.
i thought you we're my amiga
@@10MARC Wrong. What a beautiful machine the Amiga IS !!!! :) I have 2 A1200's in my home music studio.
@@frankowalker4662 I stand corrected. What a beautiful machine the Amiga IS! All my Amiga's are more fun to use than my modern machines.
@@10MARC Agreed, and easier to use.
That is so cool.
I love that PlanetX3 has become a de facto standard to show that "normal software runs"
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.
Hey Adrian, what is the story behind the packet of Smarties in the background? We have Smarties in Australia
Wonder if a video toaster version of the card would be done.
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.
@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.
14:58 - Isn't that chip 'Fat Agnus'. The one that does the DMA and hence the one that needs to be capable of access the 2Mb of chip ram.
Yes Maynards are made here in the UK
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.
There were external solutions Back in the day that could be plugged into the 23 Pin port
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.
@@adriansdigitalbasement The ICD Flicker Free Video cost about $250 to $300 in 1992
yay. a new video
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.
I've got a Toaster, but haven't used it yet, it's really neat hardware though
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.
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.
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'.
I wish amigas came out a bit earlier by the time they were out I was to busy with adult life to play games.
4:11 Is that tiny screen in the background Rickrolling me?
yes, its in every video lol
🤣🤣🤣🤣
I saw a little 3D Printed #MARCHintosh at the start of the video,
Seems like the month of March 2022 is going to be a nice one :p
Playing Dave's planet X3 very cool
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.
I just saw your OBS Studio Screen Capture flicker between 25:52 and 25:54. Also it does again between 27:33 and 27:35.
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.
awesome
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 loved my Amigas and still have them but never got passed the 2000. I'd like to have a 3000 and a 4000 but they are just too expensive.
The custom chip responsible for the maximum chip RAM amount is the Agnus.
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
Maynards candy and Humpty Dumpty chips are/were two of the best things ever to come out of Canada.
I respect the efforts to improve Amiga video.. I guess I'm old school and just prefer to have it running on an Amiga RGB monitor, imperfections and all, although I know CRTs are generally getting pretty rare.
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)
Beautiful!!! can you try some games on it?
can old laptops, those from the 90s, LCD display be replaced with today's LCD?
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.
What’s that small 4:3 screen? Does it say: Evovo?
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.
Is there any comparable solution for the A600 ?
? 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
I like some artifating :-D
PCB Card... love it!!!!!!. Maynard's ...OK
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. 🥺
I just want to say that using edibles as packaging fluff is an amazing idea.
Where's the review for the small monitor?
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
Does the a1200 have an expansion port?
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.
And we now have an A1000 version....which you probably already know by the time this video was released. :)
Ah nice! yeah figured that would be a matter of time
3:38 The timestamp says "Brideboard" lol
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.
I wonder whatever happened to my Amiga 1000. I don't really remember.
I remember interlacing. It gave me a headache.
Folks using the OSSC found a use for the SuperHiRes modes. Turns out they are perfect for modern wide-screen monitors, no squished aspect ratio.
Another 15khz machine has been enabled with the RGB2HDMI, the Apple IIgs. It requires some signal tapping off of the VGC though. Also hopefully the AGA Amigas get some love in the future although the 24-bit DAC signaling might be a bit much to handle.
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.
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.
The funny thing is this Pi Zero must be faster than 100 Amigas
Will it work for the C128?!
