It looks like one of these put in a box with a DB23 cable.

It looks like a fairly nice job. There are several posts on them recently. They are supposed to work fairly well and are 24 bit.

so he buys @$40 US and sells @$160 US?

Yeah, the US dollar is really weak in Europe these days! LOL

I think he's earning his money. He has to buy the rgb board, chassis, db23 connector, switches and whatever else he puts inside the box and I'm sure it takes him a couple of hours to put one together and test it. Not to mention the time he spent figuring out how to do it and make it work. If you buy the raw board, you have to figure out how to make it work with an Amiga in a stable configuration. Then, if one gets damaged in shipping, he has to take it back and either fix or replace it and probably has to swallow the shipping charge.

I've thought about trying one of these Arcade converters but I've got too many projects going on right now. I know I'd spend some time putting it into a chassis if I got one.

I've used this scan converter before. it's ok, but requires a little setup (thru the built-in menu).

amiman99 · « **Reply #6 on:** November 12, 2011, 02:29:52 AM »

I have the same board, works OK for $35, not worth $160.

I put mine in Radio Shack box, added 9pin connector for Amiga RGB, and I'm using 25pin-9pin Amiga monitor cable.

Have problems with PAL resolutions.

amiman99 · « **Reply #7 on:** February 18, 2012, 04:35:35 AM »

I was playing with this board again to see if I can get it to work in PAL and finally success.
The problem was with the H V Position and H V Size settings.
The main issue is that if you set the NTSC side first then the PAL will be screwed up. So I messed with settings in PAL resolution till I got good picture, then modified the settings that will work on NTSC side at the same time.
My setting for future reference:
H POS 56
V POS 16
H Size 48
V Size 59

So, not bad for $35.

Just ask if it's V4.0.

Agree!

Plus powersupply and cables. Plus time. All YOU have to do is plug it in. Why would people think that price is expensive? That's why each batch he makes sells out in no time.

Previous posts sound like a case of; "I want it all and I want it for zip!" If you want it cheaper get the card and do it yourself. For the same raw materials I bet you find yourself up around the $80us mark add the time you take to build it and,,, yep $150us.

It obviously is worth $160 because it sells for that like hot cakes..

amiman99 · « **Reply #11 on:** February 19, 2012, 04:10:19 AM »

Most of us tinker with stuff, so it shouldn't be a problem make it work. Those that can't do it, must pay the price.

My original idea and this is how I made it, see pictures:
$32 GBS
$10 Case from Radio Shack
$5 DB9 connector
$5 5v 2A PS from Goodwill
Some cutting tools and sharp knife

Pin 1 - BLACK (GND)
PIN 3 - RED
PIN 3 - GREEN
PIN 5 - BLUE
PIN 7 - GRAY (SYNC)
This is made so that you can use your existing 1084 Amiga monitor cable.
There are some 1084 cables with DIN connector, with those you are out of luck.

Any idea what happens if one of these is fed a genuine VGA signal, e.g. a productivity 640x480 screenmode? Does it pass it through unaltered? Thanks.

I just tried the Multiscan 31KHz 640x480 mode, and looks like it worked, but it was not perfect. The screen was shifter up from NTSC position, so the menu bar was not seen.
You need to play with screen controls to center the picture, also I noticed that the screen was getting brighter every few seconds.
Because Amiga can generate custom screen modes, it's kinda hard to pre-adjust all screen modes to work w/o some adjustments.
That's why I had hard time getting NTSC and PAL to work together. I have adjusted for a perfect picture using NTSC, but then PAL was screw up.
Also DBLPAL and DBLNTSC does not work, but you don't need it.

Sounds encouraging though, thanks for testing!
