> Looked on everymac.com ... The information ... http://www.everymac.com/systems/apple/network_server/stats/ networkserver_700_200.html ... is only partly correct. The standard processor for the 700 was a 150 MHz 604e, not 200 MHz. The accessory processor card for the 700 was a 200 MHz 604e. The standard processor card for the 500 was a 132 MHz 604e. The elusive 300 was never released as a model; it was only a prototype, but it did use otherwise standard ANS components in a rack mounted case. A rack mounting adapter was made for the 500 and 700. This is probably the rarest accessory item. The 700 has one or two "hot pluggable" power supply units and are fully redundant when two are installed. The 500 had a fixed supply of lower capacity. It is possible, with great difficulty, to convert a 500 to a 700 and vice versa. Here's a list of corrected notes to the everymac page on the ANS: 1. Supports parity 60 ns 168-pin and nonparity 70 ns 168-pin DIMMs. Correction: May be FPM or EDO, and these may be mixed as the DRAM controller cannot distinguish between them as all RAM accesses are as FPM, anyway. If even one RAM stick is non-parity, then parity checking is turned off for the entire machine. 2. RAM must be installed in pairs. Correction: Incorrect. May be installed in pairs for best performance, but may be installed as singles, too. Standard RAM was 32 MB for a 500, 48 MB for a 700. 512 MB is the absolute maximum, not withstanding the fact that the ANS uses a 9500 DRAM controller which has a maximum of 1.5 GB. The flaw is in the POST code within the ANS's ROM and cannot be overcome by using O.F. O.F. is particularly unstable on the ANS. It is adequate for A/IX but may not be stable enough for any but a customized version of YDL. 3. Built-in VRAM cannot be upgraded, but a PCI video card can be used. Correction: Video is proprietary to the ANS. To use anything besides A/IX, a video card which is supported by Linux must be installed. 4. Nine drive bays, seven free with one HD and CD-ROM pre-installed. Correction: The seven "free" bays are completely empty, and require a proprietary board and cable kit (sold separately and individually, in 68-pin and 50-pin versions) to enable their use. The 700 may also install two 5.25" full-height (3-1/8" high) UW-SCSI drives internally, using an accessory bracket and cable kit. The 500 does not support 5.25" hard drives. 5. Designed for use with AIX 4.1.4 (originally $1600 US), also runs Linux. Correction: Yes, but IBM will no longer sell or transfer A/IX licenses. Linux will work on the ANS, particularly if a PCI video card and a PCI E-net card are used. A Rage 128 for video and any of the DEC "Tulip" cards for E-net are fine. The video card and the accessory 10/100 E-net card for a 9500 would work well. Apple used these for an internal project to convert the ANS to Linux, but the project was abruptly canceled. YDL 3 or 4 is probably the best choice. Precompiled kernels are available, as is support for the front panel LCD status display. Linux support for the ANS's accessory RAID card is available. A standard 1/2 AA 3.6 volt Li cell is used for NVRAM backup, the same as on most Macs. The "CUDA" switch is available, but special procedures are required when installing Linux. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Vintage Macs group.
