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's own parts list for this drive ==
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. Held on this wiki inside the Service Support Training Programs binder scan, described at [[Service Support Tranning Programs Laserwriter Technical Procedures Jan 1985]] ([[:File:Service_Support_Tranning_Programs_Laserwriter_Technical_Procedures_Jan_1985.pdf]]).</ref>

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" />
