• Remarques

• The V370 module is a VMEbus master that allows Macintosh computers direct memory-mapped access to modules in up to 8 VMEbus crates interconnected by a twisted pair ribbon cable bus that can be over 50m long. With the appropriate interface cards it can be connected to all models of the original closed Macs, and all the later open Macs that used the Apple NuBus. 7323 MacPlinth is used for the 'compact' 68000-based Macintosh, Macintosh Enhanced, Macintosh Plus and Macintosh SE computers, and A410 MICRON for the 'modular' 68020-base Macintosh II and the 68030-based Macintosh IIx, IIcx, IIci and IIfx.

  The double-height single-width module includes VMEbus slot-1 functions (system clock, SGL bus arbiter, and global crate data-transfer timeout). It incorporates a release-on-request (ROR) data transfer bus (DTB) requester and a 3-level interrupt handler, and can be employed as a system controller, or as a normal DTB master in a multi-processor system. The module is powered from the VMEbus.

  The VME crates appear within the address space of the Mac's 68000, 68020 or 68030 microprocessor, so that no special software drivers are required to access them. The interfaces are largely transparent to the user, and can be used by any resident Macintosh programming system capable of reading and writing at known absolute addresses. The Macintosh can even execute code in VME RAM or EPROM, and programs resident in one crate can access facilities any of the others.

  The VMEbus controller was designed by Bruce Taylor and manufactured by Siemens-Albis SA. The controllers were used from 1984 until the mid-1990s, when new Macintosh models changed from Apple NuBus to PCI bus.
