- Macintosh IIfx Question & Answer
-
-
- Q: Do all Macintosh applications run on IIfx?
-
- A: Virtually all Macintosh applications run on the Macintosh IIfx, as do
- virtually all NuBus cards.
-
- Q: Which applications will take advantage of the new power of the Macintosh
- IIfx?
-
- A: All Macintosh applications will take advantage of the new power.
- Mainstream applications like word processing and spreadsheets will be faster
- and more responsive, as will computing-intensive tasks like scientific and
- engineering activities.
-
- Q: Do you have to be a specialized Apple reseller to sell the Macintosh IIf
-
- A: All authorized Apple resellers can sell the Macintosh IIfx.
-
- Q: With all this integration on the Macintosh IIfx, why didn't you put it i
- a three-slot design?
-
- A: There are three key reasons. First, many of our customers are OEMs and
- VARs, who take Macintosh technology and add significant value with special
- solutions. These solutions require the system's six-slot design and Processor
- Direct Slot (PDS) either for maximum expandability or maximum NuBus power.
- Second, we wanted to provide an upgrade path for Macintosh II and Macintosh IIx
- owners, hence the Macintosh IIfx upgrade kit. Third, to achieve fully balanced
- system design, we needed to integrate the built-in 32-bit cache, Processor
- Direct Slot and other features that wouldn't have been possible in a IIcx
- design.
-
- Q: How many new Application Specific Integrated Chips (ASICs) are on the
- Macintosh IIfx board?
-
- A: There are a total of seven new ASICs. Two are Peripheral Interface
- Control (PIC) Chips, which are dedicated to controlling low-level routines such
- as serial communication and floppy disk access. There is one Small Computer
- System Interface/Direct Memory Access (SCSI/DMA) chip, which controls the SCSI
- bus. There is one Operating System Support chip, which is a multipurpose ASIC,
- dedicated to managing interrupts from external sources so they are synchronized
- with the internal bus. There is one Bus Interface Unit 30 chip and a Bus
- Interface Unit 2 chip, which drive NuBus processes and bus synchronization,
- respectively. There is one Faster Memory Controller chip, which controls
- access from the cache, ROM, and RAM to the system's main processor.
- Additionally, there are four ASICs which also appeared in the Macintosh IIci
- design.
-
- Q: What are the benefits of all this integration?
-
- A: This high level of integration yields four major benefits. First, it
- opens up more space on the board for future functionality. Second, it yields
- more efficient use of power. Third, it increases overall system performance.
- And fourth, it increases system reliability.
-
- Q: What sort of advantages does the Macintosh IIfx get from the Peripheral
- Interface Control (PIC) chips?
-
- A: The PIC chips are important to the overall performance of the Macintosh
- IIfx system, as they balance the increase in clockspeed to 40 MHz by ensuring
- that I/O processes keep pace with the processor's speed. Additionally, they
- free the main processor from processing low-level interrupts. As a result, the
- PIC chips provide high levels of dedicated and predictable performance for
- standard I/O routines. For example, network routing techniques on the Macintosh
- IIfx are completely transparent to users performing any number of Macintosh
- applications. In future versions of the Macintosh operating system, the
- Macintosh IIfx will take greater advantage of the PIC chips' capabilities.
-
- Q: Why are you shipping a floppy-only version?
-
- A: By shipping a floppy-only version, we provide a system upon which
- resellers, VARs, OEMs, and other third parties can add value.
-
- Q: Are you going to be shipping the Macintosh IIfx system with NuBus cards
- installed?
-
- A: The top cover of the IIfx has a special, improved design that allows App
- factories to preconfigure the systems with NuBus cards installed as determined
- by customer demands. As manufacturing processes evolve to utilize this
- hardware capability, we will start shipping systems with customer-demanded
- NuBus cards preinstalled.
-
- Q: Are you shipping system software preinstalled like you did with the
- Portable?
-
- A: System Software version 6.0.5 and HyperCard version 1.2.5 are preinstall
- on Macintosh IIfx systems that have 80MB and 160MB internal hard drives,
- further enhancing ease of set up.
-
- Q: Will the Macintosh IIfx run System 7.0?
-
- A: The Macintosh IIfx is System 7.0-ready. It supports the virtual memory a
- 32-bit addressing capabilities of System 7.0.
-
- Q: Why did you choose to use new DRAM for the Macintosh IIfx?
-
- A: Optimizing the system's 40 MHz capabilities requires balancing the
- system's entire architecture, including DRAM access. We chose new 64-pin DRAM
- for the Macintosh IIfx because it provides a higher level of DRAM-access
- performance, as it allows the system to perform overlapped writes to DRAM
- concurrent with reads from the cache or ROM.
-
- Q: Does this mean that Macintosh II and IIx customers who wish to upgrade t
- the Macintosh IIfx have to buy new DRAM, also?
-
- A: Yes. The Macintosh IIfx-specific DRAM (which is faster and features a n
- SIMM module) is available from Apple and third parties.
-
- Q: With the Macintosh IIfx, why would anybody buy a Macintosh IIci?
-
- A: The Macintosh IIci has been an extremely well-received new product for
- Apple and the company expects it to remain in high demand. It offers customers
- high-performance and enhanced functionality in a IIcx design. With 68030/68882
- processor/coprocessor combination running at 25 MHz, and a balanced system
- architecture, it is a high-performance system. The IIcx design provides users
- with a flexible, small footprint. And its built-in video capabilities provide
- enhanced functionality. The Macintosh IIci fills an important role in the
- Macintosh product line by providing high-performance in the Macintosh IIcx
- design.
-
- Q: Are the I/O processors and SCSI/DMA fully utilized by both A/UX and the
- Macintosh operating system?
-
- A: A/UX takes full advantage of the I/O processors and the SCSI/DMA chip.
- The Macintosh operating system also recognizes significant benefit from the I/O
- processors and the SCSI/DMA as these devices relieve the 68030 CPU from
- low-level interupts and routines for serial communication, Apple Desktop Bus
- processes, floppy control, and SCSI routines. Consequently, Macintosh IIfx
- users will experience greater performance when using the system as a network
- router (managing the interaction between two separate networks) and smoother
- mouse movement, among other benefits. As the Macintosh operating system
- evolves, it will take even greater advantage of these hardware enhancements,
- just as A/UX does today. The I/O processors should be viewed as an
- architectural stake in the ground for future Macintosh operating systems.
-
- Q: Are you creating a new bus with the PDS?
-
- A: PDS, by definition, is linked to the processor. So when a vendor change
- a processor clockspeed, of course, the PDS architecture must be different as
- well. The Macintosh IIfx PDS is a superset of the Macintosh SE/30 PDS. As a
- result, it will be relatively easy for third parties to revamp an SE/30 card to
- work on the IIfx. We should point out, as well, that Processor Direct Slots
- tend to be created for very job-specific work and a hardware-specific platform.
-
- Q: What's the internal storage strategy for the Macintosh IIfx?
-
- A: We offer the IIfx in three standard internal storage configurations: a
- floppy-only version with a SuperDrive disk drive; a IIfx with an 80MB internal
- hard drive; and one with a 160MB internal hard drive. This provides customers
- and resellers with flexibility and a range of options. We believe the most
- popular IIfx configurations will be the 80MB and 160MB versions, but by
- creating a floppy-only configuration, we give customers and resellers the
- option to configure a system with more internal storage, if they want it.
-
- Q: Are there plans for a three-slot version of the Macintosh IIfx?
-
- A: We expect the Macintosh IIfx to appeal to customers who have
- high-performance computing needs. And usually these customers want maximum
- expandability as well as high-performance. So a six-slot system makes sense
- for them. The Macintosh IIci is a three-slot, 25 MHz '030 system and has been
- very popular with people who want high-performance in a three-slot design
- center.
-
- Q: Can users upgrade from Macintosh II to the Macintosh IIfx?
-
- A: A logic board upgrade is available for both Macintosh II and Macintosh I
- customers. All that's necessary is a logic board swap, as the form factor of
- the Macintosh IIfx is the same as the Macintosh II and IIx. The upgrade costs
- $2,999, manufacturer's suggested U.S. retail price.
-
- Q: Why is there no onboard video for the Macintosh IIfx?
-
- Onboard video makes sense for a more mainstream product like the Macintosh
- IIci. But with the Macintosh IIfx, we believe our high-performance customers
- will opt for as much power and flexibility as possible. As a result, one of
- the six NuBus slots can be used for the customers' video card of choice,
- including 24-bit color cards from Apple and third-party vendors. The Macintosh
- IIfx also runs the new family of Macintosh Display Cards, including the 8.24 GC
- card.
-
- Q: Why is there no Ethernet card on the logic board of the Macintosh IIfx?
-
- A: Ethernet is an important direction for the future. But until we can bot
- fit the right Ethernet control logic on the logic board while offering the same
- level of plug-and-play functionality provided by LocalTalk, we will continue
- with LocalTalk as our built-in networking interface of choice. Currently,
- NuBus provides a powerful and flexible connectivity solution. Additionally,
- AppleTalk is built into every Macintosh system, including the Macintosh IIfx.
-
- Q: Is the IIfx a workstation?
-
- At Apple Computer, we are in the personal computing business. That means we
- make broad-based tools that help people perform a wide sweep of mainstream and
- general purpose tasks: from word processing to database management; from
- desktop publishing to personal productivity. Clearly, as we add more power and
- functionality to our Macintosh architecture, Macintosh will include many of the
- features found in workstations. And consequently, Macintosh users will
- increasingly be able to perform many of the tasks that many workstation users
- perform––especially in the scientific and engineering markets. And they'll be
- able to perform these tasks in the distinctive Macintosh fashion.
-
- We view this inclusion of new customers, markets and usages as part of the
- natural evolution of the Macintosh system architecture: As Macintosh becomes
- more and more powerful, it will become the computing platform of choice for an
- ever-broadening group of people.
-
- Q: When will Apple include a Motorola '040 chip in a Macintosh?
-
- A: We have a long and successful relationship with Motorola and we will
- incorporate its new technology into our systems when it is appropriate for us
- to do so and when those components are available in enough volume to meet
- expected customer demand.
