Ok found it. The reference to the icon is at offset 0xfefe0d78 and I see the CopyBits call near there. It's also near some SCSI trap calls so feels like it will be SCSI related which makes sense since I saw the behavior with the ZuluSCSI but not a spinning disk. And I don't see this specific...

There are two SCSI related calls that utilize the _DockingDispatch trap. One is to get the SCSI disk mode and the other is something with a SCSI interrupt handler. The docking handler is probably the code in that sRsrc with ID=50.

The Docking Manager implements a _DockingDispatch trap, and one of the operations seems to be to get a special floppy icon. This calls a docking handler which I believe calls into the duo dock ROM and returns one of the icons that @joevt extracted, but not the two I'm looking for. This sequence...

Cool thanks. Last night I mapped out the code chunks in the Duo Dock ROM, looking specifically for 4E75 (RTS) and Slot Manager calls (A06E). I had most of the valid code regions disassembled. Your earlier post this morning helped me identify the data region that had the icons I was interested...

@joevt in your post #11 (in the other thread) the BBEdit file you attached has the icon I'm looking for. Of the five icons in that doc, it's #2 and #3 (it's animated). This is great and means what I'm looking for is in the Duo Dock rom. Thanks for the help!

Thanks!

@joevt @cheesestraws you guys rock as usual! Didn't even think to look at Resourcerer. Oh well, it was fun looking into PICT format and playing with it :) Ah neat! Good call. Ok. Thanks!

So that was really useful. Appreciate the help @dougg3! I was able to use the more textual doc you linked (which was actually easier to follow) and implement enough opcodes including the run length encoded bits to get what I needed. Alas, the images are cool but not the one I was specifically...

Aww man, buried down there. I see it now. But yeah, still confusing on the additional data. Thanks for the pointers though!

Thanks @chelseayr @dougg3. Maybe I need to just be more open minded :) The stuff that was confusing me as I was looking at the opcodes was for example the title of the table in that link is Table A-2Opcodes for extended version 2 and version 2 pictures so I was thinking it was specific to a v2...

I was looking through the system ROM for a PowerBook Duo 280c as part of looking into a strange icon using my duo dock. I saw what looked to be images in the ROM so I extracted out that data for 13 images and wrote a quick program that would render the images as ASCII. Here's an example of one...

From what I read in an article, the 8*24GC acceleration handles drawing asynchronously and thus expects applications to be using QuickDraw calls which have all been trapped. If any application writes directly to the frame buffer, you get issues.

I need to take more advantage of @3lectr1cPPC's vast library of documents. I keep forgetting to check the developer notes. Thanks for sharing @Fizzbinn. Should have realized that a lot of stuff is off boarded from the Duo logic board. Unrelated, but looks like even the mini dock has its own...

Unfortunately, I don't. I only have ZuluSCSI devices. Also read a blurb about ensuring the driver is updated on the disk so I ran an update of the disk driver with HD Setup and that also didn't help. Note that I don't see this issue when I'm using the Duo standalone with the same ZuluSCSI...

Yup. Brand new one that I made using new Panasonic cells. It’s working. Didn’t help. Tried this as my first step and then tried it again in my last post. Yeah, I think that’s right. But I have a working rebuilt main battery as well and my PRAM battery is brand new and charged. Does your...

You two are nuts :love:

Yeah, unfortunately that info did not help. Appreciate the link though.

I've got the driver installed (v7.0.1) and acceleration enabled. I also have the Macintosh Drag and Drop extension (v1.1) loaded. This is running in my IIfx which is using System 7.1.1. I have it set to millions of colors on a 13" monitor. TattleTech says this card is revision 1 so I assume...

Played with a bunch of the configurable settings but nothing seems to help. Don't have the cycles to debug this right now and 10 seconds isn't a big deal so going to leave it for now.

Some more interesting observations. Icon is related to SCSI, not the floppy - I disconnected the ZuluSCSI and I no longer get that icon, I get the usual question mark floppy icon. That suggests this icon is related to SCSI devices. Time for Zulu to get ready - the Zulu is ready to go super...
