Woops sorry, brain is still waking up. So addendum it does require
that the ISP be already programed into the device so if you want to
use a laptop, with usb interface to program it, and you do not have a
device programmer borrow someones prior and put the uart ISP into
it.&lt;br /&gt;
(they have this note too &lt;a href="http://www.atmel.com/dyn/resources/prod_documents/doc4218.pdf"&gt;www.atmel.com/.../doc4218.pdf&lt;/a&gt;)&lt;/p&gt;

&lt;p&gt;
The other option is to use an FTDI device that supports SPI (see
the data sheet &lt;a href="http://www.atmel.com/dyn/resources/prod_documents/doc2487.pdf"&gt;www.atmel.com/.../doc2487.pdf&lt;/a&gt;).
You will have to either &amp;#39;do it yourself&amp;#39; for the programming or find
someone who has already written the software to program it this
way.&lt;/p&gt;

&lt;p&gt;
However this thread&lt;br /&gt;
&lt;a href="http://www.keil.com/forum/docs/thread6177.asp"&gt;http://www.keil.com/forum/docs/thread6177.asp&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;
and this company might be a start as well&lt;br /&gt;
&lt;a href="http://www.xeltek.com"&gt;http://www.xeltek.com&lt;/a&gt;&lt;br /&gt;
Search for your device&lt;br /&gt;
&lt;a target="_blank" href="http://www.xeltek.com/device_search/page2.php?from_page=0&amp;amp;search_str=AT89S51&amp;amp;package="&gt;www.xeltek.com/.../page2.php&lt;/a&gt;*&amp;amp;prog_type=1000&amp;amp;manufacturer=ATMEL&amp;amp;company=0&lt;/p&gt;

&lt;p&gt;
have fun&lt;/p&gt;

&lt;p&gt;

Why did you not look at the manufacturers web site first?&lt;/p&gt;

&lt;p&gt;
Part page:&lt;br /&gt;
&lt;a target="_blank" href="http://www.atmel.com/dyn/products/Product_card.asp?part_id=1917"&gt;&amp;quot; href=
&amp;quot;http://www.atmel.com/dyn/resources/prod_documents/doc3ae686c15593f.pdf&amp;quot;&amp;gt;
&lt;a href="http://www.atmel.com/dyn/resources/prod_documents/doc3ae686c15593f.pdf"&gt;www.atmel.com/.../doc3ae686c15593f.pdf&lt;/a&gt;&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;
You should have the data sheet handy (in case there is
documentation in there that isn&amp;#39;t in the above).&lt;/p&gt;
