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.
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. 😞
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
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 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
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 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.
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 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.
So, I received mine from Aliexpress and wanted to pair it with my PC CRT monitor and Amiga 500. PSU I used is 5.2V 1.35A. After connecting it with the VGA to DB23 cable on input side and VGA output to monitor I received jumping, flicker screen. Started to research internet for solution whilst everything was on to notice after 10-15 minutes that monitor went off, was very hot and quiet ticking sound was coming out of it. That's how the CRT monitor ended his career, so I obtained LCD 4:3 monitor in it's place, to continue the battle. This monitor withstands the research process much better, though, the effect the GBS provides is pretty much the same as on previous monitor. Been trying to fiddle with Geometry to yours and other sites/videos settings but nothing seems to work... Any clue on your mind or it's just garbage to be returned?
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...
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?
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. th-cam.com/video/k5FwfJhcQXI/w-d-xo.html
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.
hahahaha lovely voise from that box... i got a 4000 dollar HP elitebook repaired in bangkok by some chinese genius in an electronic appartment store.... oh boy.. i payed him 35 dollar for the magic... love the man and his little solder shop... what a kind man and his shop workers.... i went walking in the hot sun to get his team a fresh coconut milkshake... i kid you not... my HP elitebook was fixed!!!!!! next time i fly i bet he is still there and i will again get him a bunch of milkshakes even i not have a job or order from him.... i dtill have a headache tho

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! 👍
Your no-nonsense plain speaking style is excellent. Keep up the great work. Thanks for this info.

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

Another great video, and another amiga saved your workmanship is outstanding.

Just did mine with making new cable per your instructions. Finally get a pic but flickering at very top and washed out colors
"Why'd they write up and down?" - brilliant :). Always enjoy your vids Chris.
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
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!
Nice man! I will try this soon. Otherwise ive just been using the HDMI mod instead. But still nice to have even more options.
You can mod it, to get better image and almost no artefacts.

I put copper tape on mine and soldered it to ground, it got rid of 80% of the noise.
that must be the guts of my Domcade Scandubler which has had it's input die, or my amigas output just died

maybe its the vga converter, i made a db23 for my unput.
That unit link was $23…
But still better than a scan plus AGA over $200!!
Maybe Not that much
Nice. Interesting project.
I got a usb to pin. just use a basic USB changer which is 5v 2a
Thank you 👍👍👍

Hi Chris, Could you share your Dell monitor model please?

Chris you rock!!!!
Cool! -Mark.
