I just tried the Multiscan 31KHz 640x480 mode, and looks like it worked, but it was not perfect.


Sounds encouraging though, thanks for testing!

The $5 DB9 is a worst case scenario, if I needed today at Radio Shack, I actually got it for FREE.
The 5V PS is also free from my LAB's IP Phone,the pricing is based on my local Goodwill store, and I dont think that I can find it locally any cheaper then that.:insane:

All the thrift stores near me charge a dollar or less for loose power bricks and stuff, but I could see paying $5 at a surplus store.

Has anyone managed to get the board powered from the power provided by Amiga's DB23 video port?

I wouldn't try it as the Amiga port doesn't really supply enough current.

The +5volt from the Amiga video port is meant to be 100ma max, the GBS video converter needs about 400ma minimum.

The unit draws 400mA and max draw for the video port at 5V is 100mA http://old.pinouts.ru/Video/AmigaVideo_pinout.shtml
So, I would not recommend it.

There was a guy selling these units on eBay and from memory, it was powered by the DB23 video port.

I wonder how he did it?

I'm pretty sure he stated it in the auction - a DB23 cable was soldered onto the board and that was the only cable...

the power figures from the amiga are probably fairly "safe" figures...

if you were to regulate the 12v @ 100ma, you'd probably be able to get 5volts @ 200ma ;)

combine that with the 5volts @ 100ma...

I still wouldn't do it though! lol

Fair call...  a 5V PSU isn't that much trouble to hook up to the board... :)

I totally agree it's not a bad deal assembled.

I built mine super cheap tho..  (Because I am super cheap..)

GBS-8200 - c. $32
5v2A PSU - c. $2
Black Plastic case - Free  (It came with a bunch of CA (Computer Associates) CDs in it, but we get a new pack every year..)
DB23 - Free  (Gutted an A520 RF Modulator)
Maybe 2 hours tech time - Free (and overcharged at that, if you saw my solder skills, or lack thereof..)

Ain't the purtiest, but it's working..  ;-)

TBH, I haven't used it all that much yet..  I really like my 1084s monitors.
This is more of a back up, in case of 1084s tragedy at some time in the future..

It's no Indivision, but for the money....  Not too shabby...  ;-)

I am definitely going to get one of these video converter's but I am still a little confused about inputing the RGB signal and the type of power supply used.  
Isn't it possible just to use the external RGB input on the front of the board?
Also, what are the exact specs of the power supply?  I see it's 5v and 2A, but what is the tip polarity (+ or -).  Thanks.

Any body try one of these?


For that price I prefer to buy a new Indivision.
