Thanks Carlos, this is the clearest explanation I've found, and seems to
follow the line of thought that my issue may well be pull-ups. Although
the text still suggests only that a lack of these on the data lines will
only result in higher current drain, and that alone would not be an
issue for me, since my circuit is capable of supplying well over 200mA
if necessary.

Hi guys,
When posting long urls to a list brackets keep them from getting busted:
I make it a habit even if it is really short.
Best, Dan.

Got it. Thanks. A space got added right at the line wrap in Mathias'
post, so I didn't spot it until your post moved things.

Great point. Thanks!
Probably important w/ any web based mail application w/ autowrap "features".

Hi, Al. I've been busy and not following the group. But SD
cards are interesting to me and I just noticed all the notes.
I looked at the 40-page spec cited by Matthias Weingart
(v2.2) and saw that it references an SDA Physical Layer
Specification. I assumed you have to pay for that and I've
seen that it is at least in V3.0 by now. I haven't been able
to find that one. But I did find v1.01 and v1.10. Weird
thing is, v1.01 is almost 900 pages long, while v1.10 that I
got (and haven't read yet) is slightly over 130 pages.
Another weird thing is that Matthias' v2.2 is shorter than
another v1.9 I found, which is about 3 times longer.
The SD Card association has some freely available "simplfied
versions" which I also grabbed.
Anyway, here are some links:
The MONSTER one, almost 900 pages, is the first link above.
And since I was rummaging around, I figured I'd also dump out
this link:
That is a PDF that can be printed out "actual size" on a
printer being fed with construction paper and then cut out
and glued with Elmer's to make a spectrophotometer box that
uses either a DVD-RW or a CD-ROM disk. (Use blanks, if you
can.) The DVD-R and DVD+R have a huge absorption band in the
visible red, so don't use those. The DVD-RW is great.
