Macintosh Performa 6400: Difference between revisions
Apple Service Source: the processor is a PowerPC 603ev, not a 603e; the DIMM specification differs between the Performa (168-pin fast-page 70 ns) and the Power Macintosh (168-pin EDO 60 ns) versions of the same machine; the 6420 ships with up to 24 MB and has 256K L2 as standard; the 6400/180 shipped a 4X AppleCD 600i and a 1.2 GB drive; the built-in speaker is a single MONO full-range speaker/subwoofer, stereo only via external speakers; and the input is 90-130 or 180-264 VAC set MANUALLY on... |
Red-link sweep: retarget delegation links to the pages that actually exist (LC 550/LC 580/Performa 6100 sub-pages do not, the Performa 550/580 and Power Macintosh 6100 ones do), fix the malformed 'Macintosh Power Macintosh 5400' title, and de-link targets with no page |
