Curious as I don't think it was addressed. But to make this work with an average VGA monitor will I need a GBS8200 (or similar device)? Will I lose any quality or colour?

Oh and any NTSC concerns?

Anyone has tried this with a Tandy 1000 machine? AFAIK, it should work.

I got a Tandy 1000 SL motherboard and unfortunately i couldn't get any signal from the internal Tandy RGB output, so i still do not know if this DAC cannot decode Tandy video (which is technically the same as IBM CGA) or there's a problem with the video output on the motherboard. The board is booting just fine, just can't get Tandy video. I could get video with a VGA card though.


Let me know if someone has tried this with a Tandy 1000 and got this to work or not.
 
Yes, this should let you use an Amiga monitor. They will have RGB input which this outputs. It's up to you to connect from the 15pin D on this to your Amiga monitors input however.

Also to note, some monitors will support RGBi native and do NOT require this adapter. Probably worth checking first :) (they have a button on the back for TTL/Analogue RGB).
 
Also, I would love people to post pictures of their setup using my adapter!

Photos showing how you have it plugged in and the monitor/image you are using. This obviously applies to people who I have actually sent one to :)

Lovely photos!

I like the Amiga monitor cable adapter. Is the 23pin cable hard wired at the other end? Most of the Amiga monitors I saw had plugs on the back so you could make a 15pin to monitor cable if needed.

Yeah,hardwired..no vertical moving either as you can see. I also have a 1084S-D2 that i had to make my own 15pin to 9pin cable for..worked nicely aswell,though picture isn't as nice as the m1438S in my opinion.

The 1084S-D2 also didn't like some of the VDC Mania modes, picture scrolled vertically..the m1438s feels more versatile in this regard.

There are still a few people I have emailed that didn't reply with a yes/no at all. If you are one of them, please let me know so I can offer the board along to the next person if you don't want it.
 
I'm only up to like November 2016 :( My apologies again but the bad board batches and hard to get parts really held this back.
I've posted out a dozen units in the last week so we are moving again at least. More parts are on their way with (hopefully) the last PCB revision which should speed things up a lot if I don't have to keep fixing up the board layout.

I would ask again for people to please post their photos :) I love seeing what you guys are doing with this adapter.
