The config tool can import that file (it's a human-readable text file).

There needs to be a disclaimer about audio through HDMI, as we are re-implementing parts of Paula in the FPGA in order to generate digital audio. Further, the CIA adapter must be installed to get the information about the power LED status for filter emulation (which also needs to be digital).
The audio feature wasn't in from the very start, but it was planned from the beginning. With the very few reports of audio sounding wrong or even not working, I guess we can at least list the "experimental" status and call it "beta" until a few people with very good knowledge about the real Amiga sound confirm that it's "just right"

Indivision ECS V3 has VGA-out only.
The only product we have with HDMI output is Indivision AGA MK3. This can be set to "DVI signalling" by disabling audio in the config tool.

Is there a particular reason P96 Prefs needs OS 3.2 and can't run on 3. 9 or earlier versions?
scalabilty, on top of font sensitivity. Older OS versions can't do that if I remember right.

Would be nice if you get back to us with a success/no success info and the warranty ID, then we can update that in the history of the board.

A diode for protection got shorted that was inbetween the plus and the minus.
That's D8, a 12V Zener diode that will short anything above 12V or below 0V (reversed). Part# is 1SMB5927BT3G, where the "T3G" at the end means "tape and reel", so not a requirement for your one-off-repair.
This is Q11 with the marking text H7DUQ on it,
IRLML5203 in SOT23 package.
But it only measures a diode value in one direction of all 3 pins (checked in all possible combinations).. Normally bad mosfets will shortout as far as i know?
With enough current, you can easily melt a bonding wire and have an open pin.

Yes, this is a manual process, which I'll do later today. I have relayed this additional info through the back end of the shop system - thanks.
The code will be sent to you via eMail, and it'll be available in the order history of your member login as well.

Yes, you can mount local samba shares as well. Just have a look into the mount list of the iComp drive and change the IP addresses and ports (naturally, we need to use a non-standard Samba port, so we're not filtered on the internet).

Because of the IDE speeder thing. Which would be wasted if you put it in your ACA 500 Plus.
"kind of" - while the actual IDE speeder doesn't do anything on the ACA500plus, it has it's own way of improving CF card speed that works with all ACA12xx accelerators. You will see considerable CF card speed increase with any A1200 accelerator.

I tried to load the Indivision recovery disk, but that didn't work. The Amiga wouldn't boot because of the blinking powerled.
We could not reproduce that behaviour.
Could it be because of the heat that something went wrong? It was about 30°C in the room when I turned off the Amiga the last time and so it didn't work the next day.
Temperature will only be a problem if ambient gets above 85 degrees C: This will let the junction temperature of the FPGA rise above 165 degrees C and cause it to fail at higher frequencies which are required for 1080p output. However, it should never keep the Amiga from starting. You'll see flickering after some time, but the computer should always start up.
Could I do the reflash in another way?
This is already done, the unit is back to working state. One explanation I have for your computer not starting is that you either installed it on the wrong chip (which you wrote didn't happen), or some other contact/short circuit problem that coincided with removal of Indivision. "Green screen" usually means that less than 256k of chip ram was found, in which case the computer refuses to start. You may also see such a green screen if your upper shield touches the Lisa socket pins - this is why we're writing in the manual that the shield should be modified/cut out for Indivision.

Could something like this be done for the MK4?
We're not planning any new version of the flicker fixer(s). What you're referring to is shader-based emulation output, which has no other choice than adding lag, because a full frame needs to be processed to be able to calculate the stretching/bulging of the CRT. This is nothing we actually *want* to achieve, as low-latency is top priority.
The idea of having static graphics in the left/right borders is a nice one. While we don't have space for that left in the flash, we may be able to "fake" something on the existing MK3 hardware - I'll talk to Peter about that.

Thanks for reporting back. Was it "cleaning" in the end?
-
You can/should still tie the cable down, so it does not touch the rotor.
-
Sorry for the delay - I'll send you an eMail with the offer early next week.

It was repaired today - just a re-flash, nothing else. Are you sure that you've installed it on the right chip?

Did I post 5.08v with a comma?
Sorry, that's a cultural difference: While most English-speaking countries use "point" as the delimiter after whole-numbers, many European countries (including Germany) use a comma. So if you say "one point five" in English, we translate it to "eins komma fünf", so the "point" becomes a "comma".
When a German engineer speaks of "digits after the comma", he most certainly refers to the precision given in a drawing. It does happen to me as wekk: I like to use two digit precision in my CAD system, as that's what I need for traces/spaces on the copper side. However, precision of the milling machines that make the outline of the boards is much less. Naturally, you have to design for tolerances, and PCB manufacturers check that.
However, if you're leaving the PCB manufacturing bubble and go to service companies that also make non-electronics stuff (such as the plexi things I like to use), you either have to change the drawing to only use one digit precision, or you have to do some explaining first before you send out the drawing. If you don't, you either don't get an offer at all, or it's like "looks like for a medical/military product, let's add a few hundred EUR per unit" - or they get back to you and say "we can't make it according to this drawing".
There's a lot more not-so-obvious differences in communication between Europe and other cultures - what you often see in press articles is a wrong translation of million/billion/trillion: In the US, this is 10-to-the-6, 10-to-the-9 and 10-to-the-12. However, the German word "billionen" means ten-to-the-12, because we're making a difference between "millionen" (same as in English) and "milliarden", which is 10-to-the-9 (lazy me: "to the" is short for "to the power of").
And of course there's the whole metric vs. imperial dimensions topic.. let's not go there
Just let me know what I *should* have written instead of "after the comma" in order to not be misunderstood?
I take it the safest bet for a reliable Amiga external PSU is an original Commodore unit freshly recapped with quality Japanese capacitors?
Yes, that's what I recommend until we can deliver the CA-PSU again.

but certain programs do this? 🤷🏻♂️
This screenmode is indeed weird: It has >1000 pixels on the X-axis, but a horizontal frequency of 27.64kHz. Since you are trying to map this screen to a lower-resolution screen, this is doomed to fail. Could it be that you still ahve a screen promoter running that makes the old GVP program open a non-standard screen mode? I'd expect these old programs to only open a standard PAL or NTSC screen.
In any case, you should be able to get that screen to the right proportions with live config. If you then go back to the config tool, it'll notify you about unsaved changes.

I measured the 5v rail and got 5.08v,
I'm impresse that you have a multimeter that is calibrated to be this accurate. I guess it's 6000-count at least? Where did you measure, and under what load conditions?
(yes, this is the intentional poking "do you actually realize what you're saying by quoting two digits after the comma")
I highly doublt the 50mV ripple. These after market PSUs use MeanWell chassis, and they have changed their spec to "worse than 50mV" years ago. They also don't do cable drop compensation.
I am starting to think that it might have always been on the very brink of functioning at 42mhz, and just some tiny variable has changed enough that it is now over the brink of working.
Yes, it can really be tiny things, such as a mouse adapter, a monitor solution (especially if it uses it's own power supply: These can introduce ground loops) or an internal memory expansion.
To reduce bus load, the ACA500plus has a solder-option that lets you remove the A500 68000 CPU. There is a solder-jumper near U24 that says "close jumper if 68000 removed" - this will generate the E-Clok on the ACA500plus and feed it into the machine. This is an expert's mod only, and it is absolutely necessary to remove the 68000 CPU from the A500 main board before you can connect an ACA500plus that is modified in this way. However, if bus load and/or power is the problem, then every tiny bit helps.
