		<summary type="html">&lt;p&gt;Adding stub TDC 3640 page&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;The &amp;#039;&amp;#039;&amp;#039;TANDBERG TDC 3640&amp;#039;&amp;#039;&amp;#039; is a [[wikipedia:quarter-inch_cartridge|QIC]]-120 SCSI tape streamer, used in some ND systems.&lt;br /&gt;
It can record up to 125 megabytes on a cartridge.&lt;br /&gt;
&lt;br /&gt;
== Tape format ==&lt;br /&gt;
* The QIC-120 format used by the 3640 model uses a 1/4&amp;quot; 15-track 125MB DC6150 cartridge&lt;br /&gt;
&lt;br /&gt;
== Electronics ==&lt;br /&gt;
* Two printed circuit boards: Mainboard and Sensorboard&lt;br /&gt;
* Drive electronics: [http://controls.ame.nd.edu/microcontroller/main/node3.html Motorola 68HC11] plus two custom ASICs&lt;br /&gt;
* 64KB read/write RAM buffer&lt;br /&gt;
* I/F to host: SCSI standard, revision 17B&lt;br /&gt;
* Power requirements: +5V 250mA, +12V up to 3.9A peak (start-up) (2.25W (idle) - 15W (motor running)&lt;br /&gt;
&lt;br /&gt;
== Recommended media ==&lt;br /&gt;
* QIC-120 &amp;#039;&amp;#039;&amp;#039;3M DC600A&amp;#039;&amp;#039;&amp;#039; or &amp;#039;&amp;#039;&amp;#039;3M DC600XTD&amp;#039;&amp;#039;&amp;#039; tapes (183m/600-foot)&lt;br /&gt;
* Alternatively, other high quality tapes with equal mechanical tolerances, certified for 12500 FRPI (&amp;#039;Flux Reversals Per Inch&amp;#039;)&lt;br /&gt;
The documentation is pretty insistent about this.&lt;br /&gt;
&lt;br /&gt;
== References ==&lt;br /&gt;
* [http://bitsavers.informatik.uni-stuttgart.de/pdf/tandbergData/TDC_3620_3640_3660_Reference_Manual.pdf Tandberg 3620/3640/3660 manual on bitsavers]&lt;br /&gt;
