the best for everyone, however, I’ll drop back to a group buy on the

changed to dropping the (now Atlas) right into a PC enclosure and using the ATX
power supply for power. Just need 4 stand-offs for the PC solution. <o:p></o:p></span></font></p>

font-family:Arial'>>While the layouts may be wrong for a PC they are right
for a standard rack mount (not pc) .<br>
>If the connectors are moved adjacent to the Din connectors you will now
ONLY have a PC mount.<br>
>Not a board which may be mounted in either case (chassis).. VME and cPCI
all have their boards mounted with connectors opposite >the Din...They seem
to still work..The company I work for, DRS-SS makes a VERY good living using
those type of boards.<br>
>Contrary to what Alex mentioned ATLAS may still be mounted in a PC in the
normal manner allowing the boards to be inserted and >removed without
removing ATLAS with the addition of a simple harness to the back connector.<br>
>If it is absolutely necessary to make these boards "PC" only then
at least KEEP the current designs as an alternate for the rest of >the
world...and the Antarctic.<br>

>No I don't have a SDR-1000. I have no vested interest in either method. And
no I wasn't here at the beginning. I do have a strong >interest in SDR and I
just don't think a mistake should be compounded to exclude other uses.<br>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I tend to agree with Peter’s comments. Depending on
whether the i/o connectors are located opposite the DIN or on the adjacent side
from the DIN the boards will be optimized for different uses. Personally, my
goal is to put together a compact stand alone portable rig that doesn’t
depend on an external PC. To than end, I think a more compact housing can be
found/built that is not a PC specific chassis.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

mechanical issues and very well may be preferred for some applications. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I back the proposal to fab at least some of the Janus and
Ozy boards with the connector opposite the DIN configuration (as they are
presently laid out). A second layout could always be done to move the
connectors by those so inclined (open designs encourage derivative works).<o:p></o:p></span></font></p>
