I'm totally confused about the Compaq model numbers because the
Compaq web pages seem so hard to navigate (missing pages etc).
The model we've developed on is the H3650 that is shipped in the
US with a USB base.  I was told that in some other parts of the world, it ships
with a serial base.   We had to order serial cables for it (just soldered
together the first one and got a few more from Jim Gettys till
more arrived).  The H3650 has 32 MB ram and 16 MB of flash.  If
you were really lucky and got the first batch of H3650's they had
32 MB of flash because Compaq was having a hard time getting 8 MB
flashes and ended up using 16MB chips (the flash is interleaved
across 2 16 bit wide chips to create a 32 bit wide word).

There is now an H3670 that is the same as the H3650 but with
64MB of ram.

Looking at the Compaq site, the H3635 appears to be an H3650
that just costs more.  I'm not sure why, neither was Consumer
Reports.  It may be that it comes prepackaged with an expansion
sleeve, or more software or something, I really don't know.  It
does claim to be the Internet solution so maybe it comes with
a modem.  I've sent mail to compaq asking about the models but
haven't gotten a reply yet, I'll try Jim Gettys later today.

Jim Gettys and George France from Compaq have been incredibly
helpful in getting things going.  They even came down and
visited for a few days.

There's also a cheaper H3100 series that has a 15 level grey
scale screen instead of the 12 bit color of
the H3600 series.  The H3150 has 16MB of RAM and costs
noticably less than the H3650.  We haven't seen one
to play with.  I assume the major diff is just figuring
out the display.  There are linux sources available
from the Compaq guys at www.handhelds.org and once
you know the chips, all of the info is on the net from
the manufacturers.  It was the least painful port for
me to date.

I have constant orders out for more Bitsies.  They are
always backordered and every now and then one filters in.
The most amazing was the first order I placed that filtered
in 10 months later.  I also managed to find a few in a truck
arriving at a Circuit City.  It helps to just ask when
they're expecting more, buy them before they show, and then
wait with your arms out when the truck shows up.

I remember from 9fans that the flash had to be erased
to run Plan 9 on the 3635. Would that be still the case
on the 3660?
