An Apple 3.5 Drive (A9M0106) looks similar but has no internal processor; if a drive is being sold as a UniDisk, the model number on the label is the thing to check. | An Apple 3.5 Drive (A9M0106) looks similar but has no internal processor; if a drive is being sold as a UniDisk, the model number on the label is the thing to check. | ||

Apple published an '''Illustrated Parts List''' for the UniDisk as Section 4 of its ''UniDisk | |||
Technical Procedures'', which is held here inside the Service Support Training Programs binder | |||
described at [[Service Support Tranning Programs Laserwriter Technical Procedures Jan 1985]].<ref name="lwtp85">Apple Computer, ''Apple LaserWriter Printer Technical Procedures'', preliminary version for internal use only, sections stamped rev. Jan 85 and rev. Feb 85.

The same binder carries the '''DuoDisk Analog Card Chip Swapping Chart''', which is component-level | |||
and applies to the closely related DuoDisk analogue card. Apple's warning there is worth carrying | |||
across to this drive as well: inspect the card for melted or broken components before changing | |||
anything, because a card connected to a computer '''with the power on''' typically shows "fuzz" and | |||
an exploded capacitor.<ref name="lwtp85" /> | |||
