The Apple Development Platform ADP2,1, as the systems are officially designated, features 3.6GHz Pentium 4 processors with 2MB of L2 cache operating on an 800MHz bus with 1GB of RAM.
The Intel systems run Mac OS X 10.4 Tiger identically on the surface as ordinary Macs, with the exception of a modified Processor System Preference (from Apple's CHUD tools) that allows the user to toggle Hyper-Threading on or off. Apple System Profiler includes a new line under Hardware listing CPU Features; for the 3.6GHz Pentium 4 this comprises a rather lengthy list of technical acronyms: FPU, VME, DE, PSE, TSC, MSR, PAE, MCE, CX8, APIC, SEP, MTRR, PGE, MCA, CMOV, PAT, PSE36, CLFSH, DS, SCPI, MMX, FXSR, SSE, SEE2, SS, HTT, TM, SSE3, MON, DSCPL, EST, TM2, CX16, and TPR.
Apple's System Profiler reports the graphics card as an Intel Graphics Media Accelerator 800. Inside the Intel Mac, DVI support for the video card is provided by a Silicon Image Orion ADD2-N Dual Pad x16. Oddly, neither Silicon Image's Web site nor Google turns up much information on the latter card, the latter yielding a single link to a recent Dell support forum posting.
The motherboard on the system is unmarked except for the word Barracuda. The system's internals are housed inside a case similar to Apple's Power Mac G5 systems but with a different configuration of fans.
Along with running Mac OS X, Windows XP installs without hitch on the Intel-based Mac, just as it would on any other PC, and booted without issue when installed on an NTFS-formatted partition. The only misbehavior sources encountered involved the video card. Initially, Windows refused to budge from an 800x600 setting on a 23-inch Cinema Display. Some prodding managed to get the screen to 1600x1200, but sources were unable to get Windows to take advantage of the entire screen.
