@Melkhior Could you also mix in an LC PDS slot? You could use that slot for ethernet. LC PDS ethernet cards can still be had for just $15. Although I guess you could just integrate ethernet onto the motherboard. However, having a //e Card inside a II-style machine would be cool.

Would it be possible to make the NuBus slots 40 MHz? They could slow down 1/4 speed to 10 MHz or 1/2 speed to 20 MHz for NuBus 90. This would give it PCI speed & bandwidth for any new cards designed to take advantage of it.

@willmurray461 Well with no one posting links, would you mind posting the AC ROM?

It did as I predicted. :) I'm guessing the disk header tells the drive to just ignore the other head when it thinks it's a single sided. Whichever platter is face up, that's the side it reads. So this would require some low level floppy hacking to make a double-formatted disk. Or design a...

@willmurray461 Ah, thanks. Although I'm pretty sure it's already been dumped. I was wondering if someone had all the ROMs stored someplace. I just recently picked up a ROM programmer (for arcade ROMs), so I can finally dump and program other ROMs. I was keen on installing the Apple ROM on my...

Does anyone have a link to all the Radius ROMs plus the Apple 24AC ROM?

I really like those EIZOs, but they appear to be rather expensive.

No, no! Just rest a pair of thick black rimmed taped glasses on top of the case. :)

@killvore Your Quadra 700 is such a nerd with its pocket protector.

I wonder what would happen if you erased an 800K floppy as 400K single sided, then physically flipped the platter inside the disk, and formatted the other side. Would need to separate the hub from the disk as well, flip it, and reattach it with some glue. I think the disk would probably work...

I don't recall if it was that disk specifically, but the Famicom on Japan used a similar one that they modified. That's what I was thinking. As I said, in an alternate universe, I could've seen the original Sony 400K becoming flippable to save money on having an extra head for double sided...

PlaysForSure is an interesting one. I wonder how much music people could recover if they had access to it.

As a side note: I think it'd be fun as a general hobby to invent your own media. 3D print your own floppy disk and drive. Like some alternate universe. A flippy 3.5" disk and drive would be fun. It would also make some sense given the original 400K single sided disks and the way that the...

@joevt I do know they can be formatted in cleaver ways. There are floppy disks that are formatted for Amiga / C64 / Atari. They have a single area where the respective files are stored, then there's some fancy ways they write the tracks, headers, etc. so that the disk appears to be one format...

Was the Macintosh used at the premiere a 512K fat Mac? Or was it a 256K Mac? Because it only need a little bit more to do the demo.

I was just curious if it's possible to format each individual side of a double sided disk. For example, format an 800K disk as two 400K single sides. Or a 1.4MB disk as two 720K sides.

Holy cow. Nice find.

I saw someone make an SD card floppy drive. I think it'd be cool to build something that can do that. Take a real 800K drive mechanism and motor, modify it so when you insert a special floppy disk with an SD card instead of a floppy platter, it connects perfectly to the SD slot pins. Then...
