On most Mac II and later machines, it's like this:
</p>
<ul>
<li class="level1"><div class="li"> 0x00000000-0x3fffffff = RAM</div>
</li>
<li class="level1"><div class="li"> 0x40000000-0x4fffffff = ROM</div>
</li>
<li class="level1"><div class="li"> 0x50000000-0x5fffffff = I/O</div>
</li>
<li class="level1"><div class="li"> 0x60000000-0xefffffff = NuBus “super slot” space</div>
</li>
<li class="level1"><div class="li"> 0xf1000000-0xffffffff = NuBus “standard slot” space</div>
</li>
</ul>
<ul>
<li class="level1"><div class="li"> 0xfe000000 = VRAM (SE/30 only)</div>
</li>
<li class="level1"><div class="li"> 0xfeff0000 = VROM (SE/30) (note that
while the main ROM has a valid driver at the end, SE/30 has a separate
64 kbit VROM on the board which I dumped. The actual driver is very
small, it contains mostly hardware credits for the SE/30)</div>
</li>
</ul>
<p>
Note that Macs with on board video except for the SE/30 typically
contain one or more valid video drivers in ROM; the correct one is used
when the machine type is identified.
</p>
<p>
I/O devices are given as offsets from 0x50000000. Each device is mapped across 0x2000 bytes unless noted otherwise.
</p>
<ul>
<li class="level1"><div class="li"> VIA1 at offset 0. May also be mirrored at 0x20000 and 0x40000.</div>
</li>
<li class="level1"><div class="li"> VIA2 at offset 0x2000 on II, IIx, IIcx, and SE/30</div>
</li>
<li class="level1"><div class="li"> SCC (Z8530) at offset 0x4000</div>
</li>
<li class="level1"><div class="li"> SCSI (pseudo-DMA w/DRQ on II, handshake on SE/30) at offset 0x6000</div>
</li>
<li class="level1"><div class="li"> SCSI (normal) at 0x10000</div>
</li>
<li class="level1"><div class="li"> SCSI (pseudo-DMA, no DRQ) at offset 0x12000</div>
</li>
<li class="level1"><div class="li"> ASC (Apple Sound Chip) at 0x14000</div>
</li>
<li class="level1"><div class="li"> IWM/SWIM (floppy) at 0x16000</div>
</li>
</ul>
<ul>
<li class="level1"><div class="li"> VDAC (palette) at 0x24000 (IIci, IIsi, LC series, Color Classic)</div>
</li>
<li class="level1"><div class="li"> RBV/V8/etc registers (partially emulates VIA2, also video registers) at 0x26000 (IIci & IIsi, LC series, Color Classic)</div>
</li>
<li class="level1"><div class="li"> RBV VRAM at 0x1000000 (IIci)</div>
</li>
</ul>
<p>
The entire I/O space mirrors every 0x20000 on Mac II, IIx, IIcx, and
SE/30. IIsi and IIfx mirror every 0x40000. IIci and Color Classic (and
LC series?) do not mirror. The ROMs use this mirroring behavior along
with other markers to determine the model they're running on.
</p>
<p>
The bottom 8k or so of RAM contains significant system data on these Macs. See <a href="http://www.osdata.com/system/physical/lowmem.htm#Mac" class="urlextern" title="http://www.osdata.com/system/physical/lowmem.htm#Mac" rel="nofollow">Low Memory Globals</a> and <a href="http://www.mac.linux-m68k.org/devel/macalmanac.php" class="urlextern" title="http://www.mac.linux-m68k.org/devel/macalmanac.php" rel="nofollow">Mac Almanac</a>
for lists. Note that on the IIci/IIsi the video frame buffer is at
physical address 0; the 68030 MMU is used to remap addresses so software
sees address 0 elsewhere and thus the low-memory globals work as usual.

<h1 class="sectionedit6" id="hardware_ids">Hardware IDs</h1>
<div class="level1">
<p>
There are 3 ID schemes used on the various 68020/030/040 Macs. The first
uses bit 6 of port A on VIA1 (PA6) and bit 3 of port B on VIA 2 (PB3)
and works like this:
</p>
<div class="table sectionedit7"><table class="inline">
<thead>
<tr class="row0">
<th class="col0 leftalign"> Model </th><th class="col1">PA6 </th><th class="col2">PB3 </th>
</tr>
</thead>
<tbody><tr class="row1">
<td class="col0 leftalign"> Mac IIx </td><td class="col1 leftalign">0 </td><td class="col2 leftalign">0 </td>

<tr class="row2">
<td class="col0 leftalign"> Mac II </td><td class="col1 leftalign">0 </td><td class="col2 leftalign">1 </td>

</tr>
<tr class="row4">
<td class="col0"> Mac IIcx </td><td class="col1 leftalign">1 </td><td class="col2 leftalign">1 </td>
</tr>
</tbody></table></div>
<p>
The second uses 4 bits in VIA1 port A: bits 6, 4, 2, and 1 (PA6, PA4, PA2, and PA1, respectively).
</p>
<p>
This second scheme is further indexed by the core ASIC type detected by
the Universal ROM. The PowerBook 170 and Classic II have the same ID
bits, but that works because the PB170 and Classic II have very
different core ASICs that are easily detected as different. These bits
also are used to differentiate machines with the same ID word such as
the Quadra and Centris 610/650/800.

The third and most scalable is a machine ID register at 0x5ffffffc. The
top word must be 0xa55a to be valid. Then bits 15-11 are 0 for consumer
Macs, 1 for portables, 2 for high-end 68k, and 3 for high-end PowerPC.
Bit 10 is 1 if additional ID bits appear elsewhere (e.g. in VIA1). The
rest of the bits are a per-model identifier. Updated and corrected
January 2, 2012: confusion between “Blackbird” the IIfx codename and
“Blackbird” the PowerBook 5×0 codename resolved, and many new ID values
added on through the end of the Old World.

<li class="level1"><div class="li"> IWM (Integrated Woz Machine) -
original controller, simply a small ASIC encapsulating a slightly
enhanced version of Woz's original Disk II state machine. Used in Apple
IIs, the Lisa, and the Mac 128/512/Plus/SE/II.</div>
</li>
<li class="level1"><div class="li"> SWIM (Sander/Woz Integrated Machine)
- IWM with significant additional capabilities for MFM disks. 100%
back-compatible with the IWM (actually contains 2 complete controllers:
an original IWM and the new MFM-capable Integrated Sander Machine, or
ISM. A crossbar switch inside the chip determines which of the cores is
connected to the inputs and outputs). Even in MFM and 1.44M modes,
requires the CPU to do all the low-level timing-intensive work of disk
I/O, just like the original Disk II.</div>
</li>
<li class="level1"><div class="li"> SWIM2 - Cost-reduced SWIM. Apple
figured out how to use the ISM side to read/write GCR disks as well so
there's no IWM or crossbar switch, and the GCR-side software drivers are
very different as a result (MFM is the same). Some ISM-side advanced
features that were never actually used went away also.</div>
</li>
<li class="level1"><div class="li"> New Age - Apple/NEC co-designed
controller based on the PC standard NEC765 controller with GCR
capability added. Was used in only a few machines and quickly replaced
by SWIM3.</div>
</li>
<li class="level1"><div class="li"> SWIM3 - SWIM2 with a state machine
front end and DMA capability. Similar overall capability to New Age, but
a very different programming model (and probably a lot cheaper).</div>
