Editing Amstrad PC1512 Service Manual (section)

== What it settles ==

'''The FD-3 floppy drive is documented at a level no other Amstrad manual here matches.''' Pages 3&ndash;14 give a full diagnostic flowchart, a diagnosis procedure, '''parts exchange procedures''' (printed circuit board, lever frame assembly, stepping motor assembly, and the rest, each with its own figure), and then '''adjustments and checks''' — spindle speed adjustment, track sensor adjustment, '''index burst time adjustment''' and a '''resolution check''', each with the CE diskette and equipment required. This is a real alignment procedure, not a description of one.

Amstrad's own warning is printed at the head of it: the flowcharts are for information only, and for warranty purposes the drive is an exchange item.

'''Technical specification''' (page 2): 512K system unit with all circuitry on a single motherboard; '''8&nbsp;MHz 8086'''; expandable on the motherboard to 640K; integral colour graphics adaptor with a special 16-colour high-resolution mode; '''three full-size compatible expansion slots''' with power available in the standard unit for a hard disc and controller; one or two 360K 5.25-inch floppies, or one floppy with a 10 or 20&nbsp;MB hard disc; RS232 and parallel interfaces with standard connectors; loudspeaker with volume control; '''battery-backed real time clock and configuration RAM'''; socket for an 8087; light pen connector.

The two monitors have their own '''alignment instructions''', and the colour monitor has its own '''power supply schematic''' — which matters, because on the PC1512 the power supply is in the monitor.
