  NationMaster - Encyclopedia: Macintosh IIsi   (Site not responding. Last check: 2007-11-01)
Motorola 68030 Processor from a Macintosh IIsi The Motorola 68030 is a 32-bit microprocessor in Motorolas 68000 family.
Processor Direct Slot or PDS, was a solution (actually, a whole number of different solutions) introduced by Apple Computer, in several of their Macintosh models, to providing a limited measure of hardware expandibility, without going to the expense (in both desktop space and selling price) of providing full-fledged bus...
It was followed by a more compact version with fewer slots, the Macintosh IIcx, and a version of the Mac SE powered by the 16-MHz 68030, the Macintosh SE/30 in 1989, which did not use the -x designation for obvious reasons.

 PDS: The Processor Direct Slot
Even the new compact model, the SE, had an expansion slot - it was the first Macintosh with a processor direct slot (PDS).
By creating a slot that duplicates each of these, it is as though the card were directly connected to the processor.
This slot was also used in the LC II and Color Classic, both of which used a 16 MHz 68030 CPU.

  Macworld: Upgrade Your Processor
Processor upgrades are available from such companies as PowerLogix (512/795-2978, www.powerlogix.com), Sonnet Technologies (949/587-3500, www.sonnettech.com), and XLR8 (800/513-9744, www.xlr8.com) and range in price from just under $200 to over $1,000 for dual-processor G4 upgrades.
Likewise, where the processor resides in your Mac model is likely to vary from our instructions, but the general process for removing the old processor and inserting a new one applies.
When adding the new processor be sure that the tabs on the bottom of the card line up with the tabs in the processor direct slot.

 Processor Direct Slot - Wikipedia, the free encyclopedia
Processor Direct Slot or PDS, was a solution (actually, a whole number of different solutions) introduced by Apple Computer, in several of their Macintosh models, to providing a limited measure of hardware expandibility, without going to the expense (in both desktop space and selling price) of providing full-fledged bus expansion slots.
Thus, PDS slots tended to be CPU-specific, and a card designed for the PDS slot in the Motorola 68030-based Macintosh SE/30 would not work in the Motorola 68040-based Quadra 700.
The one notable exception to this was the PDS design for the original Motorola 68020-based Macintosh LC.

 mac_ii.html
The Macintosh II family is based around the Motorola 68030 processor with exception of the Macintosh II which had a Motorola 68020 processor.
The direct cache and memory operated at 40Mhz, while the rest of the bus operated at 20Mhz.
This is identical to the Macintosh SE/30 PDS slot.

 Networking Basics: Common Issues to all Architectures
VESA Local Bus: This short-lived technology was essentially a direct line between peripheral slot on the motherboard and the processor, very similar to Macintosh bus technology.
Macintosh developed PDS, processor direct slot, and NuBus both of which involve a direct connection between the processor and peripheral slot.
Direct Memory Access - a little better than the shared method, but it uses up a DMA channel that other devices might need to talk to the processor.

 Processor (Computer Science Course Library Documentation)
Class Processor is the abstract base class for all document processor objects in the Document Workflow System Version 6.
The processor takes a tuple that matches the constant string in slot 0 plus the processor's own name in slot 4.
The processor removes the next remaining processor from the array in slot 5 and makes that the current processor in slot 4.

 PIN-OUT: Apple Macintosh Portable Processor-Direct Slot (PPDS)
The Euro-DIN 96-pin PDS expansion connector on the main logic board is physically and electrically identical to the 68020 Direct Slot used in the Macintosh LC.
This slot provides direct access to all of the 68030/020 data and address signals, and a selection of control signals.
This signal is an input to the processor logic glue.

 Desktop
In microcomputers such as the Mac, the processor is a single integrated circuit called a microprocessor.
Expansion slots are narrow sockets into which you can install expansion cards, which implement special functions not otherwise supported by the computer.
A processor direct slot is connected directly to the system bus on the logic board, giving an expansion card direct access to the CPU and RAM.

 Dale Adams on the Fall '93 '040 Macs
Note that this is not a processor direct slot on these machines, although it is on earlier LC models.
Since the LC slot was defined as a 68020/68030 PDS, and these new machines have a 68040 processor with a different processor bus, there is a bus adapter necessary to convert 68040 bus signals to those required by the LC PDS definition.
Because of this, the LC slot does not actually sit directly on the 68040 processor's bus, and hence is not a true PDS.

 Apple - Mac mini
Inside its petite 2-inch-tall, 6.5-inch-square anodized aluminum enclosure, Mac mini houses the fast Intel Core 2 Duo processor, an 80GB or 120GB hard drive, a slot-loading Combo drive or SuperDrive, as well as built-in wireless — all whisper-quiet.
This modular design lets you upgrade your current system to the elegance, simplicity, and reliability of Macintosh without a lot of extra expense.
Some options must be installed by Apple at the factory; the rest can be added in-store at an Apple Retail Store or an Apple authorized reseller.

 Wikinfo | PDS
It was a solution (actually, a whole number of different solutions) introduced by Apple Computer, in several of their Macintosh models, to providing a limited measure of hardware expandibility, without going to the expense (in both desktop space and selling price) of providing full-fledged bus expansion slots.
This was Apple's first attempt at a "low-cost" Mac, and it was such a success that, when subsequent models replaced the CPU with a 68030, and later even a 68040, ways were found to keep the PDS slot compatible with the original LC, so that the same expansion cards would continue to work.
The current standard for adding video cards to PCs, known as Accelerated Graphics Port or AGP, may be considered to be somewhere in-between a PDS and a bus.

 Power to the Max!
This card, in turn, can be placed in a processor direct slot in a PCI Macintosh or Macintosh Clone, as in my PowerCenter 150 desktop case.
It is VERY important to make sure that the processor card is seated completely i the slot, pressed down as far as it will go.
I know that playing an MP3 file is quite processor intensive, but I never had this problem using my old CPU card, which, as I've said, is slower than the G3 units.

 NiMUG - The Northern Ireland Macintosh User Group
So I have gone down the processor upgrade path and have been exceptionally satisfied with the results.
Let's face it, the Mac itself has a 40MHz bus on board so anything else was likely to mean that the extra expense on the card was a waste of time and money.
So this is what is known as the PDS slot or the Processor Direct Slot.

The IIci has 3 Nubus card slots, a processor direct slot (PDS), and a ROM simm slot, as well as the usual array of Mac ports around back.
The ability to upgrade the processor was what originally attracted me to the IIci - '030, '040 and even PowerPC processor cards are available.
3 PCI slots just doesn't seem like enough to some people, so 6 slot Macs are a prize (the S900 is much cheaper than similar Apple 9500/9600 machines).
