Indivision AGA Mk3 / CD32 - default output is beyond monitor sync range

I have an NTSC CD32 and just received my Indivision AGA Mk3 today. Aside from the cable issue that I posted about in another thread, I'm having a hard time getting output on HDMI connection. My monitor sends a notification that the signal is out of scan range and tells me to set the output mode to 1920x1200@60Hz.

Is this because the Indivision outputs at 50Hz by default? If so, is there an easy way to switch it to NTSC refresh rates? If so, where would I find the software for the CD32/4000D version? It looks like the downloads are all geared toward the A1200 version.

Quote from Jens

The default output is a 60Hz async mode that every single monitor should be able to display. We do NOT switch on VSync by default because not all monitors support it. The goal of Indivision AGA has always been to be plug&play.

Did you buy directly from us, or from a reseller?

Jens

I bought it from a reseller - Amiga of Rochester here in the US.

Hi Jens. Thank you for looking into this. As it turns out, the crystal oscillator was mounted in such a way that it prevented the socket from fully seating against the Lisa chip. With encouragement from Thomas, I was able to move the oscillator just slightly to the right, which allowed the Indivision to sit flush with the board. It is working as I write this.

The only issue at the moment is that on HDMI, the screen is offset to the right by a fair bit on my Dell U2410. It is operating at 800x600@60Hz while the native resolution is something like 1920x1200@60Hz -- so I think this is just a monitor issue, or perhaps there is a better resolution to set it to.

I did run the recovery disc for CD32 and it flashed the unit. However, the software on that disc (Indivision Prefs) crashes when launched from the AmigaOS version that shipped with my TF330. I am continuing to experiment with this, but I am confident that the board is good from a hardware perspective.

Again, thank you so much for your support!

I'm still having a bunch of odd behavior with this thing and I'm not sure what the deal is, but it seems to reset to some kind of bad state when the power has been off for more than a few minutes. Here's the scenario...

1. Cold boot the system = no display

2. Switch monitor input to RGB - display is up, but not provided by Indivision

3. Open Indivision.prefs and it warns "IndivisionAGAmk3 hardware not found. Continue?".

4. Switch the system off, boot from recovery CD. Flash happens automatically and Indivision displays as expected, but output are offset to the right.

5. Boot into Workbench, run games, whatever - everything is fine, but offset to the right.

6. Power down system, walk away for 10 minutes, turn back on. No video until I use the recovery disc again.

It's almost like when it's powered down it reverts to some mode the monitor doesn't like. Is it possible the NV memory is corrupt?

Also, when trying to save firmware to the device, I get "The configuration is not saved to the device", but no explanation as to why.

Between myself and Thomas from Amiga of Rochester, we figured out the issue - it's PSU related.

Long story short, I needed a slight voltage bump on the 5V rail. Clues to the resolution were found in this thread:

I just wanted to take a moment once more to thank you for all you do for the retrocomputing community. I appreciate your time and guidance.

That's a common theme in the retro computing world. I'll make a version of the CA-PSU for the CD32 later this year, then this problem will be solved.

Jens

Yeah, I'm discovering that not just with my Amigas, but also my C64.

Both of my Amiga PSUs are based on the Meanwell PT65b. One was built by Ray Carlsen (somewhat famous here in the US as a power supply builder) and the other is retrofitted into a stock Commodore PSU case. Both PSUs use the same square DIN connector required for the A500/600/1200, but I have a Keelog adapter for the CD32's 4-pin round DIN.

With my A1200, I had to bump the +5V rail in order to ensure the PiStorm/rPi had enough voltage to operate at full speed. I assumed the same would be required for the Ray Carlsen supply, which I was using with the CD32 -- but that was not the case after I wrote here last night. Switching back to the original CD32 PSU pretty much solved this problem (there are still some occasional no video conditions, but they are often solved with a toggle of the power switch). I'm a little hesitant to use the original PSU as it looks identical to the old C64 PSU that I know is infamous for failure-related damage to connected devices.

In the thread I cited earlier, I see that you provided a quick utility to wake the Indivision at boot. I am going to integrate that into my startup-sequence - once the Indi is awake, it's good until the next cold boot regardless of the PSU used, so I think that solves my problem.
