Ha ha, yes! The sorry part is I may well have been involved in those threads! Technical details like this tend to flee the memory. I'm about to post a whole series of questions/mysteries/theories about the early Mac Software disks, and I keep getting this sense of deja vu as I pull it together...

Yes. General information on MFS and System 7.5 at "System 7.x: Limitations on Use of 400k Disks" -- https://support.apple.com/kb/TA47951 System 7.5 can't directly format MFS disks, but Disk Copy 4.2 does it in the process of making the disk. It sounds like maybe you've stripped the resource...

Nice. Keep the rev A ROMs, obviously. Thanks for pointing to that 2016 thread. I knew about the three different Macintosh Plus 128k ROMs, but not about the revision of the 64k ROMs in the 128K/512K -- which makes perfect sense. I gather the switch from rev A to rev B occurred in August 1984...

Thanks! This is quite useful. Sounds like you will have to rewrite the last page of the Floppy Emu user manual!? I imagine this is old news to many here, but here's the current work flow I'm using to move my Disk Copy 4.2 disk images from the SE FDHD ("SuperDrive") running 6.0.8 that I've used...

That sounds like the ImageWriter I cord (not sure about II), and maybe other Japanese-made peripherals. LaserWriter (Canon)? If you put them in a Mac, they point up instead of down.

Something I learned today, which makes sense, is that if you create a .dmg in High Sierra on an APFS system, you get a APFS-formatted .dmg! This is of course obvious, but somehow it hadn't occurred to me. They're fine for people running Sierra or High Sierra, but anyone using OS X 10.11 and...

I'm sorry, I'm an idiot. Of course the "rear panels" (buckets) were empty and the "identifying marks" (badges) were glued in at some point. So if there was remaining inventory as I claimed, it would have just been of badges, not whole buckets! I think it makes sense that the "Macintosh 128K"...

I believe that week 47 date for the last of the "Macintosh" buckets and the first of the "Macintosh 128K" buckets is accurate. I don't know if the week when they started using the redesigned 820-0086-F motherboards inside 128K Macs is known. If it was like the buckets, they had inventory to get...

Note: FWIW, this appears to have happened in the 47th week of 1984 (November). Apparently, the serial numbers support this conclusion. You don't find the "Macintosh" badge on the back after that week. So the second-generation 128Ks were shipping by December 1984.

A few more comments on this disk. I'm confident that this is an Apple disk (I own the copy shown above), even though it doesn't come from Manufacturing and thus doesn't have a part number and so on. I've seen other copies of this particular disk, from other sources, and there's a Printer...

This one I'm not at all sure about (the additional label could easily just be something a dealer made, rather than Apple's doing -- the use of "upgrade" instead of "update" makes me think that), but this may have been what the April 1985 "System Update" (System 2.0 Finder 4.1) disk sent to...

On the topic of missed chances to preserve something interesting and increasingly difficult to find again, here's a photo I pulled from eBay long ago: This was probably System 3.0 Finder 5.1 (1.0a1) and I know for sure there was a second one of these, version 1.0a2 (likely System 3.2 Finder...

Here's what the dealer used to do that:

That disk wasn't what we were talking about, but it does have an interesting story. It's one of only two disks that have Finder 5.2 on it -- the other one is version 1.0 of the Printer Installation disk (basically just an update for the LaserWriter). System 3.1 Finder 5.2 was supposed to be...

Yes, "System 0.97" is System 1.0. Basically they weren't sure if it was going to be considered the final version or a demo version when they brought it to the factory at the manufacturing deadline, so it still had its beta number (hidden from most users, but they would have changed it if they...
