Hi all,

I am a newbie to the forum, and (almost) newbie to Macintosh systems. I recently acquired a Macintosh SE/30 and a Macintosh Quadra 650, and I'd like to try my hand at software development. In particular, my idea was to port the old Minix OS to the Macintosh SE/30 (for starters) as a native OS, rather than an application running under System.

My stumbling block is documentation on hardware, like memory maps, registers definitions etc.

I found this technical note:

https://developer.apple.com/legacy/library/#technotes/hw/hw_14.html#//apple_ref/doc/uid/DTS10002483

which refers to Macintosh SE/30 Developer Notes (part number M0061LL/A, which I haven't been able to find anywhere.

Some development notes can be found here:

http://developer.apple.com/legacy/library/documentation/Hardware/Developer_Notes/Macintosh_CPUs-68K_Desktop

Which I *think* has the same information as:

http://web.archive.org/web/19990424023012/http://developer.apple.com/techpubs/hardware/hardware2.html

but the former is not directly accessible, so if the contents are the same, there is no trace of specific documentation for the Mac SE/30 (and also the documentation on the Quadra 650 is scant at best.)

I have the Apple Guide to Macintosh Family hardware 2e, but it does not go too deep into details. Would the Designing Cards and Drivers be useful? I have seen the 2e quite cheap, but the price for the 3e is steep. Would the 2e be useful at least for SE/30?

Also, do any of the Inside Macintosh volumes deal with actual hardware of the SE/30 and Quadra 650? I know the first three volumes deal with the early Macintosh, but my understanding is that the architectures changed quite a bit.

Thanks in advance for any and all information you can provide,

Cheers,

Antonio
