X68000 Pro (CZ-652C) Floppy Drive Capacitor Replacement
Unlike the other models in the range, the X68000 Pro uses full-size 5.25“ drives; it's one of the main things that contributes to the significant weight increase of the system compared to the upright models.
Note: The capacitor lists here only apply to the X68000 Pro with floppy drive model “Sharp CMECF0015CE01”, also known as “TEAC FD-55GFR - Part numer 19307350-60”. Do not use this list for any other drive type:
| Number | Location | Capacitance | Voltage | Notes |
|---|---|---|---|---|
| C1 | Edge connector board | ??? | ??? | This is an all-black part with no rating label! |
| C2 | Edge connector board | 22uF | 10v | |
| C3 | Edge connector board | 100uF | 10v | |
| C4 | Edge connector board | 10uF | 25v | |
| C11 | Edge connector board | Ceramic, labelled as: SR 104M 12v | ||
