- E418: The 23$ Amiga Flicker fixer/Scan doubler? This is the GBS8200, a super inexpensive board on ebay (and elsewhere) that you can wire a DB23 Amiga connector to and play on a normal VGA display. with multiple inputs and settings, you can finally run your "newer" monitor with your old 15khz amiga rgb port.
the gbs8200 was 23$ and the db23 connectors were $8.75 each
it took me 5 minutes to solder in the wires shown where in the video.
Thanks for watching!
here are some general ebay searches from ebay usa.

modding with GBS Control is the way to go. There are multiple options to the mod process beyond adding the ESP controller. The 3 control pots are terrible, and nearly every mod starts with cutting those out and replacing them, as well as a few strategically placed capacitors. Once done, they become pretty GOOD devices, at a much lower cost. For all of us with faulty mk.1 eyeballs, more than sufficient.
I just wanted to write that. Gbs-control is whole new level for crappy stock GBS8200
I second all this, gbs control and all the mods makes a massive difference! 👍
1. There is a alternative firmware for it called gbs-control.
2. I think you can use VGA DB15 input insted of this pin connector. Take good old quality VGA monitor cable (proper shilding) and solder DB23 on one side or use DB23 adapter.
3. I bought mine few years ago for 16$ but never used it ;)
For testing and moving icons is great. For dynamic games...ehh after mods can be usable. 23$ + some work its a win win
Another great video, and another amiga saved your workmanship is outstanding.
You can get a much better picture by covering the bus lines on the bottom of the pcb with aluminum sticker tape to reduce interference. Check one of the Retro Caveman videos

The amiga RGB cable need some resistors to not risk blowing up the monitors/tvs RGB input. It may work without resistors for an extended time but eventually somerhing may blow. 😞
I suspect you already know about the mod to this, gbs-control, it will make the image quality 10 times better. It is well worth the job.
10 times?
Todd would have told us 16x
"Why'd they write up and down?" - brilliant :). Always enjoy your vids Chris.
You can mod it, to get better image and almost no artefacts.
Nice man! I will try this soon. Otherwise ive just been using the HDMI mod instead. But still nice to have even more options.
Nice. Interesting project.
Chris you rock!!!!
i wish these had a nicer, crispy image to it but it washes out and makes everything soft. Also someone should really make a compact version that could fit inside a amiga to make a cheap hdmi conversion with audio
Just did mine with making new cable per your instructions. Finally get a pic but flickering at very top and washed out colors
Thank you 👍👍👍
nice video
Been using one for a few years now coupled with the GBS Control firmware. The 2A power requirement is a myth, it quite happily runs 0.5A power supply also. I used an old nokia power supply for mine.
The little wavey lines can be eliminated by covering the data lines from the ram on the rear of the card.
Use copper tape to cover just the length of the data line.
Cheap and works.
Sorry posted it before you mentioned it 😉
Done!
Cool! -Mark.
Nice!
That unit link was $23…
But still better than a scan plus AGA over $200!!
Maybe Not that much
The copper tape worked on mine. The hardest bit is printing a case for it, to make it look priddy and ready for prom night.
Where does the copper tape sit exactly?
@@hidden_vault on the underside, its a bit trial and error but mine is in the area where the signal tracks goto the silicon. I also soldered a tab to ground for both my squares of tape, with a short bit of single core cable.
@@pkf4124 thx
that must be the guts of my Domcade Scandubler which has had it's input die, or my amigas output just died
Done this for my Amigas a few yrs back , funny thing is mine gives ghosting with mouse pointer on a normal HDMI screen that has VGA connection but if I plug it into a 15 hz modern screen ghosting isn't there.
I put copper tape on mine and soldered it to ground, it got rid of 80% of the noise.
I got a usb to pin. just use a basic USB changer which is 5v 2a
Yeah my MiniMig1.97ITX needs a flicker fixer, no matter what mode I put it on it flickers. Even flickers on the VGa to HDMI.
weird mines crystal clear on 31 khz, make sure your jumper is set to 31 khz not 15!
Al-you-minny-um, like Jesus pronounces it ;-)
I have noticed that if you use the Amiga DB23 to DB15 (390682-01) on the GBS picture will flickers in interlaced modes but if you use the homemade cable there is no flicker. Anyone know why or how to make the Commodore 390682-01 or -03 work with interlaced modes with no flicker on the GBS?
Hiyauuuu power adapter! 😊

Chris which 3d printed case did you end up using ?

@@ChrisEdwardsRestoration thanks Chris..
Got my GBS and DB23, great valentine's present from my wife, set it up and yeah an improvement in picture quality. the copper tape work around worked well. just need to do the printing. what colour?. have a black a1200 and out of black filament so looks like silver it is. Thanks Chris for video...
Hi Chris, Could you share your Dell monitor model please?
Dell U2410-F
Go Jing jingba😂 is Great
I have bee using the GBS8200 on my Amiga 1000 for years. It works great! I purchased a special version from a Canadian team, and it came with some resistor fixes. And all the 'updates' to give it a really solid image. It also came in 3d printed case, along with the Amiga RGB cable built in. It works great! I love it.

Yeah there are NO instructions besides yours! I connected up an old wall wart plug +5V 2A supply, and ...nothing! Prob my old PS. The multivoltage PSU jobbers on amazon are smart but I seem to lose just the right connector plug on every one of them...sigh
(😢2 weeks later...) This unit *does not* work with my PAL A1200- I can't get into the geometry menu to change anything, and it shows 60 Hz on my eyoyo mini monitor- so i guess anyone with PAL is SOL.
China!
Great video!!!!! Thank you so much!
Hero topic... years ago... my amiga and c128 monitors... my vga pc crap and amiga 1000 and a sweet 500..... the headaches!!!
