I am trying to get my ACE2b installed into my Amiga 2000 rev 4.1 motherboard. I've pulled Gary out and seated the socket correctly, also cleaned the contacts in there. Also cleaned out the Agnus socket as well. Did that a few times actually. But the machine won't display anything on the screen with it installed. As a sanity check I reinstalled Gary and Agnus directly and it will display the screen again at boot.
Another thing to note, I have a 3.1.4 kickstart rom.

Not that it matters, but the agnus I have is a PAL one. I'm in the USA. From what the manual stated the ACE2b should start in NTSC. So I don't think that would be it?
-
Every product that leaves here has passed a single-unit test. I does not matter if your board currently has a PAL or an NTSC Agnus.
Please take a picture of the board without and with ACE2b installed - maybe I can spot something.

So I reinstalled it again. It's something with my monitor and the ntsc and frequency. I loaded up amiga test kit and hit escape to jump to pal. I can see the screen.
-
Funny - normally it's the PAL frequency that monitors don't like. If you describe your monitor setup (monitor type, connector used on the Amiga), we may be able to find a fix.
-
It is a AOC e2051n monitor connected to a db23 to vga adapter. (Buffered i think)
-
So J102 is open on this mobo. I think I might have opened it for the PAL chip that was in there. Should I jumper it back?
-
Should I jumper it back?
The Agnus on ACE2b does not see this jumper setting. It doesn't even have an input pin for it
Google doesn't return anything with the monitor type "e2051n". Do you have a paper manual that shows the technical data, specifically the supported H/V frequencies?
-
No, I'm not even sure where I came up with this monitor. And I haven't found anything about it either. I guess I'll just build a rgbtohdmi for it. I know my other 2000 has been picky on what shows up.
-
I robbed my video slot rgbtohdmi card out of the other 2000 and I can see NTSC from this one. So it's just something weird about my 2000's and the modern monitors. I'm just going to build another card for this box and set it up like this as well. Opens up more monitor options anyhow. Also was able to install 3.1.4 on it and get that working. So no fault of the ace2b.

Try Indivision ECS V3
