I would also recommend redesigning the battery circuit to use a safer chemistry. The chemistry that the 3.6 volt lithium batteries use is extremely toxic in addition to being corrosive.
A single-session disc can still have a partition table with multiple partitions, and this is common with classic Mac discs, as well as tricky stuff like ISO9660/Mac hybrid discs.
cue/bin is preferred in general, but conversions to iso are fine. Even so, special handling (e.g. mounting...
Is this "iso" file a full disc image, or a volume image? A full disk image needs to be mounted with
hdiutil attach -imagekey diskimage-class=CRawDiskImage
for it to work.
A cue/bin image would have to be converted/extracted; I usually use bchunk for these conversions.
cdrdao can be used...
Sorry — I'm referring to the component that takes the analog magnetic data off the disk, as read by the head amp, and converts it to a digital "0" or "1".
The rotational speed can be measured from the flux data, but the tracks can't be aligned as there is no absolute reference to go by. As the built-in tachometer output on the Sony 3.5" drive isn't that good, the index sensor is necessary to capture this data. But as referenced above — the index...
Not being able to vary the disk drive speed causes issues where the data separator / transition detector circuitry in the floppy drive has trouble detecting the transitions correctly. This makes it more difficult to read and especially write Macintosh GCR disks with a PC floppy drive — I believe...
It is USB 3.0 SuperSpeed. It uses an FPGA board and a Cypress FX3 board.

Yes, it should be able to convert to DC42 or cooked image, and...
Looking at the schematic on the last page of the PDF, specifically the lower right hand corner:
J1 10PINPWRCON is the connection to the internal greyscale board
U12 IH5341 is the switch that controls whether built-in SE/30 monochrome or graphics card greyscale is used
The internal greyscale...
I’ve recently used one of these with a Linux VM on a modern Mac to image an 80GB SCSI hard disk. Yes it took a while.
Key takeaway: the adapter is not USB powered, but rather is powered by SCSI termination power. I used a Jaz drive to inject termination power, but another method could be used...
That’s the awesome part about the Applesauce — it hooks up to a real Apple floppy drive.
As for software support of WOZ imaging, I’m afraid the SWIM isn’t quite good enough for that, but if someone wants to do it please be my guest!
Best way is probably an AppleSauce controller paired with the appropriate floppy drive. It can handle 5.25" Apple II, 3.5" 400K/800K, and soon 1.44MB as well.

This is how the 3.5" flux-level disk imager looks:
Don't use DC 6.x, it does not preserve all the data on...
I finally uploaded the Micron Xceed schematics and source code that I have and they can be found at the below archive.org URL.
I believe these are for the Color 30 card, but I'm not certain. Hope this makes for useful information!

There's some information here about this thing that's fairly useful:

The structure of this ROM is as follows:
3 MB on ROM SIMM
1 MB on flash chips
The ROM SIMM is not supposed to change, but the Flash chip can and did during development. This was the reason for only 3MB being checksummed: the last 1MB, which resided on the Flash chips, could easily be changed...
None of these dumps seem have valid checksums. Could they possibly be redumped?
When dumping, always take multiple dumps and verify that they match. If you've done this and they do match, then something weird is going on.
Thanks!
