一位技术爱好者对1994年产的Apple Workgroup Server 9150进行了一次全面的重建与升级。[1]这台机器原配80MHz PowerPC 601处理器、512K L2缓存和最多264MB内存，配备DDS-2磁带驱动器、2倍AppleCD 300i Plus光驱以及原厂A/UX能力。[1]经过修复和改造，作者将其升级为配备Sonnet 400MHz G3 NuBus处理器卡、HPV PDS视频卡和ZuluSCSI存储模拟器的系统，后者集成了三个4GB磁盘镜像。[1]
升级过程涉及多项技术挑战。[1]原机器的塑料外壳因增塑剂挥发而变脆，作者采用尼龙螺钉和活页夹重新固定逻辑板。[1]最终系统成功配置为Mac OS 8.6与MkLinux R2双启动。[1]MkLinux R2基于Linux 2.0.38-osfmach3内核，集成Mach 3.0微内核、glibc 2.1.3和XFree86 3.3.6。[1]由于Mach内核对虚拟内存哈希桶的硬性限制，内存配置被设定为-m191作为最大可靠方案。[1]
值得注意的是，MkLinux官方仅声称支持NuBus Power Mac 6100/7100/8100系列，但实际上与WGS系列也兼容。[1]
An enthusiast has completed a comprehensive restoration and upgrade of a 1994 Apple Workgroup Server 9150, transforming the aging workstation into a dual-boot system running both Mac OS 8.6 and MkLinux R2 [1]. The machine originally shipped with an 80MHz PowerPC 601 processor, 512K L2 cache, and support for up to 264MB of RAM, paired with a DDS-2 tape drive and 2x AppleCD 300i Plus optical drive [1]. The restoration process addressed hardware deterioration caused by volatile plasticizers; the original plastic components became brittle and required replacement with nylon fasteners and binder clips to secure the logic board [1].
The upgrade involved significant enhancements across multiple subsystems [1]. A Sonnet 400MHz G3 NuBus processor card replaced the original CPU, while a ZuluSCSI storage emulator was integrated with three 4GB disk images and an HPV PDS video card was added to the system [1]. The MkLinux installation runs version R2, built on Linux 2.0.38-osfmach3 with Mach 3.0 microkernel, glibc 2.1.3, and XFree86 3.3.6 [1]. A critical memory constraint emerged during configuration: the Mach kernel applies a hard limit on VM hash buckets, making -m191 the maximum reliable memory setting for stable operation [1]. Though MkLinux's official support documentation lists only NuBus Power Mac models (6100/7100/8100 series), the Workgroup Server 9150 proved compatible with the distribution [1].
