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.

@lokz9632 11 месяцев назад

I just wanted to write that. Gbs-control is whole new level for crappy stock GBS8200

@NEOGEOJunkie 11 месяцев назад

I second all this, gbs control and all the mods makes a massive difference! 👍

@mophus6461 11 месяцев назад

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

@daw7563 11 месяцев назад

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. 😞

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

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?

@DatBlueHusky 11 месяцев назад

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

@C64_and_Amiga_Memories 11 месяцев назад

Nice man! I will try this soon. Otherwise ive just been using the HDMI mod instead. But still nice to have even more options.

@davidwright9166 11 месяцев назад

Just did mine with making new cable per your instructions. Finally get a pic but flickering at very top and washed out colors

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.

@hidden_vault 11 месяцев назад

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.

@technretro7115 11 месяцев назад

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 😉

@ChrisEdwardsRestoration 9 месяцев назад

Done!

@wowtechniplex 11 месяцев назад

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?

@wimwiddershins 11 месяцев назад

I put copper tape on mine and soldered it to ground, it got rid of 80% of the noise.

@pkf4124 11 месяцев назад

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.

@hidden_vault 11 месяцев назад

Where does the copper tape sit exactly?

@pkf4124 11 месяцев назад

@@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.

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.

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. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-k5FwfJhcQXI.html

@drphilxr 11 месяцев назад

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.
