<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">Well, as you will find out I don't
design in hardware or software, but sort of just a devils advocate. Also
thoroughly addicted to reading spec sheets and web links you guys come up with
. One thing I'm sure of is that it is not going to be trivial or someone
would have started with a Gb Ethernet port and stacks instead of, or in
addition to the High Speed USB. </span></font></p>

<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">I dabble in Access programming on
occasion, and one thing I have found is that it is most times harder for me to
copy an entire database program and make it a different program by 'removing
and replacing parts'. After attempting it too many times, I have realized
it was just better to do a new design and use the 'experience' from
previous databases and small parts of the database to generate something new
and better. </span></font></p>

<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">Hence my suggestion of something
along the lines of Epimethius. I find the description of Epi on the Wiki
interesting!</span></font></p>
<p><font face="Times New Roman" size="3"><span style="font-size: 12pt;" lang="EN">From
Encyclopedia Mythica? "Epimetheus ("afterthought") is the son of
Iapetus and Clymene. He foolishly ignored his brother Prometheus' warnings to
beware of any gifts from Zeus*. He accepted Pandora as his wife, thereby
bringing ills and sorrows to the world". </span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">Or just start from scratch and rename to something
original. Use the best from all ideas! Your honors!</span></font></p>

<br>
Thanks for the welcome. <br>
<br>
Why an Ozy... Well, in looking through the list archives, I found Lyle's
message from February 11th calling for project leaders. He mentioned the Ozy
with a Gb Ethernet controller. If there is a better/different idea, I'm open. <br>
<br>
One thing about a Gb Ethernet board, it's not going to be simple.<br>

<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">Ozy is pretty dedicated (at the moment) to Interfacing the
SDR-1000 with it's large DB-25 and a number of other custom devices dedicated
to the purpose of talking with SDR-1000.</span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"> </span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">Why not an Epimetheus? Dedicated to 'other I/O' functions? I
think I've seen quite a number of chips dedicated to making dumb devices like
table lamps and such, into web servers etc, why not an HPSDR i/o board?. Aside
from the Atlas being a little 'slow' for a Gig backbone that is true whatever
board it is put on. </span></font></p>

<p><font face="Times New Roman" size="3"><span style="font-size: 12pt;">Hi to the
list,<br>
<br>
My name is Warren Walsh - K2BM, I'm new to the list and the hpsdr site. That
being said, I have volunteered to look into an Ozy board with a Gb Ethernet
interface instead of the USB port. Are there any general guidelines that I
should following? If anyone has any ideas already, I'd be happy to hear them. <br>
<br>
Thanks and 73,<br>
