			The embedded file is Apple's ''Macintosh Classic/Classic II/Performa 200'' ''Service Source''. Two copies are hosted here: [[Macintosh Classic/ Classic II/Performa 200 Service Source]] (115 pages) and [[Macintosh Classic / Classic II Service Source]] (113 pages, the copy embedded above). They are the same manual; the longer copy's '''Light Meter Setup''' topic covers three meter models (R77, L-248 and 246) where the shorter covers two.

			Two things the manual settles for this machine: the PRAM cell is '''lithium and is replaced below 3.0 V''', measured with the logic board out and the CRT discharged;<ref name="ssclassicbatt">''Macintosh Classic/Classic II/Performa 200'', Apple ''Service Source'', Additional Procedures, Battery Verification - hosted on this wiki as [[Macintosh Classic/ Classic II/Performa 200 Service Source]]. "If the battery voltage is below 3.0 volts, replace the battery." The procedure's "before you begin" is remove the cover, discharge the CRT, remove the logic board.</ref> and there is '''no power-supply voltage adjustment''' for this family - Apple's Adjustments chapter is light-meter setup, video and yoke only, so the rail-tolerance figures published for the Macintosh 128K, 512K and Plus do not apply here.

	The '''Macintosh Classic''' was introduced by Apple on October 15, 1990, as a low-cost alternative in the Macintosh lineup and a spiritual successor to the original Macintosh 128K and SE. It retained the same 9-inch monochrome display and compact form factor, but included a 1.44 MB SuperDrive and optional internal SCSI hard drive. It was the first Macintosh to sell for under $1,000, making it a popular choice for schools and home users.
