Sure, excuse me. I got this pop-up window which says: "This disk is unreadable by Macintosh. Do you want to initialize the disk?".

Well I burned it in x8 speed (the lowest Snow Leopard burning speed I can choose) and it doesn't work. Click to expand... Can you be more specific than "it doesn't work"? Does …

Well I burned it in x8 speed (the lowest Snow Leopard burning speed I can choose) and it doesn't work.

It's a disk 'image'. It contains all of the neccisary HFS formatting. THe disk burning app reads byte 1, writes byte 1. reads byte 2, writes... etc

Ah.... so it's actually the paper copies before (and including?) Vol VI that are worth picking up, assuming you want to do any development for System 6 or lower? The hardware info…

my original idea which i never started or attempted, but ill throw it out there for you if you want to do it this way: My idea was to make an external floppy emulator that plugs i…

Just got hold of Apple Recovery CD, Booted it with the help of an external CD and voila !It was a dream. Now all I need are the Diagnostics for LC III so I can check if all is ok.…

I've got the opportunity to pick up the paper edition of Inside Mac vol. VI - the huge one. Click to expand... It contains all the System 7 introductions, eg process Manager, A…

Just as a whiney aside, I'd love to find PDFs of "Inside Macintosh" volumes IV and V, IV particularly. My Google-Fu has failed me miserably on those... no, wait, I'd never just Goo…

I'd assume that your Q605 uses a Mitsubishi, since a lot of manual-inject Macs from that era have Mitsubishis. Click to expand... Yes, that does sound familiar. I haven't opene…

That's likely. Apple probably got a different manufacturer to create the slimmer drive needed in the laptop. I noticed that the drive in the Quadra 605 (with dust flap and differen…

Dog Cow, there is no way the UniDisk will work on a Mac with it's "smart" circuitry intact. It's the equivalent of hooking an electrically compatible Disk II. As for the Lombard P…

While we're on the subject: I've got the opportunity to pick up the paper edition of Inside Mac vol. VI - the huge one. Is it worth it, compared to a PDF? Yes, I do prefer to re…

Just to be clear on these points: The 800K 3.5" drive for Apple II (UniDisk) is identical to the drive mechanism used in the Macintosh. The only difference is that the Apple II ver…

I'm going to be putting some old Mac tech notes which had been posted in comp.binaries.mac on my site later this month, but there's probably all of them on Apple's site already. Th…

I used to have the URL for where Apple keeps the PDFs of Inside macintosh and the tech notes. I can't find my bookmark and my google-fu is failing me. Anyone have it handy?

Well good news and bad news. I decided to take a look at the Developer Note for the LCIII and it states this. The Macintosh LC III uses a new floppy disk controller circuit,…

There is the early 800K 3.5" drive for the Apple II which has its own 6502, buffer RAM, and IWM chip inside and which talks to the host like a HD20. There is the 400K Sony drive in…

I wonder if I still have that. Click to expand... While searching for it, please also remember to keep an eye out for your MacDraw schematics.

Just to make things interesting, Apple has a bunch of different floppy drives with different software interfaces which all plug into the floppy port / IWM / SWIM / IBM chips. There…

Well about the time I pulled out the soldering iron I realized something. If I want to understand how the drive works it would be much better to spy on it while the Mac is using it…

I did some research and found that the SWIM and pretty close to the IWM. I took a look at the Linux Mac floppy driver code and apparently a command is sent to the drive it switch i…

If anyone has a link to a document chronicling the secret recipe for speaking to an HD-20 it might be an apropos time to trot it out. Click to expand... We've been begging for…

Anders, That's a very generous offer - and I may very well take you up on it. I'll see about buying the caps off Trag first though. It's be nice to get my SE/30's going again - e…
