The PCI bus arbiters are also identical (343S0182). On the PCI bus, as mentioned above, the ANS uses the Bandit PCI bridge, just as the PM9500 does. The ANS does have eight memory DIMM slots instead of the PM9500's twelve, but other Hammerhead-based machines such as the PM8500 also carry only eight memory DIMM slots. However, the memory structure is the same with two banks of DIMM slots and support for memory interleaving when corresponding slots in different banks contain identical memory DIMMs.
The ANS memory data lane controllers are 343S1161 instead of 343S1141 as on the PM9500. The memory data lane controllers are different on the ANS from the ones on the PM9500, presumably because of added support for parity memory. However, on the ANS the clock buffer which splits the System Clock for all the CPU Bus Devices is on the logic board, whereas on the PowerMac 9500 the clock buffer is on the CPU card. On both systems the CPU Bus Clock is supplied by the removable CPU card. All devices at the CPU bus level are identical between the ANS and PM9500. Both the ANS and the PM9500 have two Bandit controllers and two separate PCI busses. The CPU bus-to-PCI bus bridges are Bandit controllers (343S0020). The CPU, as mentioned, is a PowerPC 604 or 604e. Starting at the top level bus and working downward in the bus hierarchy, at the top level is the CPU bus with a Hammerhead controller (Apple Part # 343S1190) which is also found on the PM9500. While the circuit board layout of the Apple Network Server (ANS) may resemble RS/6000 systems, logically and physically it is almost identical to a Power Macintosh 9500 (PM9500), although running quite different firmware, and which is specific to its unique mission function. On the other hand, many logic board components, especially the Open Firmware boot ROM, are similar to the "Tsunami" board used in the Power Macintosh 9500 and some Macintosh clones. The general logic board layout seems to suggest a close relationship with PowerPC-based RS/6000 systems by IBM, which also were designed to run AIX. Whether related to the hardware change or by coincidence, Apple also abandoned its NetWare on PowerPC development (codename: Wormhole) at this time.
USED APPLE SERVER MAC OS
In order to move forward and ship the product, Apple made modifications to the Power Macintosh 9500 logic board and ROM (locking out all Mac OS calls) and ported AIX to the new hardware. During the development of the hardware, Apple abandoned the original mainboard design for unconfirmed reasons. The Apple Network Server's hardware was supposed to be based on a new logic board design specific to the product. CEO Gil Amelio cancelled both Network Server and OpenDoc in the same meeting as it was determined that they were low priorities.
The product's short lifespan is attributed to significant financial troubles at Apple in early 1997. Apple did not have comparable server hardware in their product lineup again until the introduction of the Xserve in 2002.
USED APPLE SERVER SOFTWARE
market for $11,000, $15,000 and $19,000, respectively.Īpple Network Servers are not to be confused with the Apple Workgroup Servers and the Macintosh Servers, which were Macintosh workstations that shipped with server software and used Mac OS the sole exception, the Workgroup Server 95-a Quadra 950 with an added SCSI controller that shipped with A/UX-was also capable of running Mac OS. This makes them the last non-Macintosh desktop computers made by Apple to date. The machines were not a part of the Apple Macintosh line of computers they were designed to run IBM's AIX operating system and their ROM specifically prevented booting the classic Mac OS. It was codenamed "Shiner" and originally consisted of two models, the Network Server 500/132 ("Shiner LE", i.e., "low-end") and the Network Server 700/150 ("Shiner HE", i.e., "high-end"), which got a companion model, the Network Server 700/200 (also "Shiner HE") with a faster CPU in November 1996. The Apple Network Server (ANS) was a line of PowerPC-based server computers designed, manufactured and sold by Apple Computer, Inc.
