It's basically a floppy emulator using a ST or Artery microcontroller. There isn't much else to them hardware wise. Commonly used for replacing floppy drives in pretty much anything that uses an IBM/Shugart interface or variations.

I'm not entirely sure about compatibility with all standard PC drives, I haven't done much testing there. I've heard others have tried standard PC drives, some worked and some didn't. I don't really have enough variety of 3.5" drives around to test it. Floppy emulators work with 1.44MB MFM disk...

You still need the Outbound floppy controller board, since that's where the floppy controller chips live. But it works with both the internal and external floppy boards.

They're only for providing the original LCD panel the signals it needs, the external output leaves those signals out and expects whatever device is on the other end to get by with the bare minimum of just the byte clock and frame clock, which technically the other two clocks could be derived...

I think I'm just going to throw together an adapter to use an optical mouse for the VCF display. Probably more reliable than the ball mouse at least.

Apple made a ROM card, but I haven't ever seen it used outside of the prototypes.

The part number for the receptacle is 535697-6. I think NTI is a good supplier of them. The part number for the other connector on the CPU board that goes to the motherboard should be 104652-8. Here is TE's page: https://www.te.com/en/product-104652-8.html I believe 5-104652-8 should be the...

After buying around 5 random mice off eBay with very little description or pictures, I finally found a mechanical one: It has the FCC ID E6Q5J8BUSMOUSE and not much else on it. I still have the one floppy drive I can't seem to get working. I think it used to do more, but now only the motor...

It's totally possible. Although as you can see in those pictures the 9.7" iPad display is a bit too small for the bezel, so you lose a good bit of the display area. With a larger display, you can fill more of the bezel at least: The capacity of the battery doesn't matter that much, just as...

I doubt it would have been Apple since this was just a standard connector AMP would have sold to others as well, as with most of their massive catalog. It's interesting since that's the one that's easy to get today. I have a few of them in their original tape. It's the connector that goes on...

It appears it just tests each format one by one until it finds a match. https://github.com/rezafouladian/OutboundRE/blob/ccec0bcc17a2ccefbd3f50eb772de7d652414cfc/FloppyEEPROM_1.3.s#L2928

Well if you mean the assembly text files themselves, that's all done by hand. I've only tested external so far. I'll have to see if I can put an internal floppy setup back together again. I have this weird issue with one of my internal power boards. It was likely caused by the main battery...

I'll have to see if I can find where the floppy emulator went, that image does work fine on an original drive at least. For the disassembly? Just Ghidra.

Actually now that I go back to look at my code, I did have to tweak it since it's a DSTN display output and scans both halves of the screen in each clock.

The video signal is basically the same as the one from the Macintosh Portable (aside from the different pinout) though it also supplies HSYNC and also runs at more like 76Hz rather than 61Hz it seems. For my video decoder setup at least I don't even have to change the code, just the pinout.
