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.

They were originally intended to be battery backed SRAM, though they later could have supported flash.

This is just in the Snow emulator at the moment. You could likely fake it on real hardware if you have between 5.5-9MB of RAM, but you would need to fake some of the hardware. You would need to pull high bit 3 of 0xFC0200 and bit 3 of 0xF00000 and/or 0xF00030, and likely make sure other bits...

They do work just fine since the entire driver is in ROM: Getting it in the Powerbook 100 would be tricky, since you need both access to the bus as well as the signals from the CPU GLU, at least to implement it the way Apple intended. As I understand the SLIM cards got delayed because they...

Just in an emulator. I think I got the RAM disk working in it now, looks like there's just a few registers for controlling the address lines on the RAM.

Yeah 8 modules, I tried both 1MB and 4MB modules in the RAM disk slots, as well as none at all, the behavior is always the same. I would open the control panel if the mouse worked. I think the EEPROMs are version 1.2.1, I can't remember if I updated them. I also accidentally discovered that if...
