Excitement anf faith in a technical project only get you so far, sometimes it
clouds judgement. <br>
<br>
What I'm advocating is the same thing Bob said in his reply to my post. We need
to use sound engineering practices and reviews to go through the designs. There
is no hurry to get a passive backplane out the door, better to wait and get a
high quality, working system sometime "this summer". Just building
something without making sure it works does not help to advance the
state-of-the-art for amateur radio. If there are unforseen design problems, it
will only frustrate people trying to use the HPDSR and hurt the process.<br>
<br>
There are still a number of basic questions unanswered, things like, but not
limited to:<br>
What are the form factors for the plug-in cards? <br>
What are the specifics of the ATLAS bus (some of it is written down, but there
are a bunch of blanks)?<br>
Is a 10MHz or a 1pps reference signal going to be supported? If so, it it going
to be distributed over the backplane? <br>
Are the JTAG connectors going to be put in a common location on the top of each
plug-in card? <br>
Does OZY have the throughput to handle both a MERCURY and a JANUS board
operating at the same time? <br>
<br>
What the project need is some design documentation, so that folks who want to
design a curcuit know how to integrate it in. I'd be tickled pink with some
block diagrams!<br>
<br>
So, yes, I would hold my order until the group has a baselined design for
JANUS, OZY and ATLAS. JANUS is going through a redesign currently! If I have to
I'll run a set of boards myself.<br>
<br>
I am more than happy to work on documentation, but it's going to take lots of
questions and the corresponding answers.<br>
A valid answer to a question can be "we don't know yet".<br>

blanket on the enthusiasm, but why order the boards for ATLAS when there isn't
a reviewed and baselined design for the JANUS and OZYMANDIAS cards? The better
thing to do would be order the three board set at once. <br>
<br>
What if a date is sat to complete design reviews on OZYMANDIAS v1.0 and
JANUS v1.0? How about June 8th?<br>
If the date is met, then shoot for board ordering in mid-june.<br>
<br>
Personally, I'm thinking of ordering a couple, but I'd like to see that there
is a working system, not just a passive backplane.<br>
<br>
I've read that the ATLAS is using standard PC case spacing between cards. Are
the actual cards going to have a physical size of a full-height, half-length
PCI card (so as to effectively use the PC-case)? <br>
<br>
What is being done is good, but just like building Eagle, there has to be a
little order and structure and documentation.<br>
I'm willing to contribute with the documentation and coordination, because this
is one of the "skunkworks" of amateur radio.<br>
