=== Chipset Notes ===&lt;br /&gt;
&lt;br /&gt;
* The part numbers printed on the chips may look like &amp;quot;KPxxx&amp;quot; (cyrillic) instead of &amp;quot;KRxxx&amp;quot; (latin).&lt;br /&gt;
* As mentioned at chipdir, KR1802IR1 is similar to AM29705, but '''NOT''' the same (the AM29705 has four additional data pins).&lt;/div&gt;</summary>
