Editing IBM 5114 Diskette Unit Parts Catalog

The '''IBM 5114 Diskette Unit Parts Catalog''', order number '''S131-0626-1''' (September 1978), is IBM's illustrated parts breakdown for the IBM 5114 Diskette Unit. 59 pages.

'''Figure 13, Power Supply Assembly''', is the reason this catalogue matters for restoration. It is the only document on this wiki that lists the individual capacitors of a 51xx-family power supply as separate orderable parts:

'''No capacitance or voltage rating is given for any of them.''' The catalogue is a stores-ordering document.

The one- versus two-capacitor variant matters: the [[IBM 5110 System Logic Manual]] notes on sheet 440 that some power supplies do not have C2, and that on those machines fuse F1 is 8 A rather than 10 A.
