<p>Documentation page for newly hosted Apple developer documentation</p> <p><b>New page</b></p><div>&lt;pdf width=&quot;800&quot; height=&quot;500&quot;&gt;File:Macintosh IIfx Special Options and Technical Information.pdf&lt;/pdf&gt;<br /> <br /> Download it here: [[:File:Macintosh IIfx Special Options and Technical Information.pdf|Macintosh IIfx Special Options and Technical Information.pdf]]<br /> <br /> This is Apple Computer&#039;s own developer documentation for [[Macintosh IIfx]], published in 1990. It covers the IIfx&#039;s proprietary 64-pin SIMMs, its SCSI arrangement and termination requirements, and the options Apple offered on the machine. This copy is a scan and has no searchable text layer.<br /> <br /> Apple&#039;s developer notes are a different document from the &#039;&#039;Service Source&#039;&#039; repair manuals: the Service Source tells a technician which module to swap, while the developer note gives the electrical and architectural detail — rail currents, connector pinouts, power budgets and chip functions — that a repairer needs in order to make a go/no-go measurement. Several figures on this wiki are cited to this document.<br /> <br /> == See Also ==<br /> * [[:Category:Apple Documentation|Apple Documentation]]<br /> <br /> [[Category:Apple Documentation]]<br /> [[Category:Apple Vintage Computers]]</div>
