I just realized that I had an old O2 XDA lying in a drawer running Windows Mobile 5. My core is 0810 so the orbiter download links don't work and only after much searching have did I find a link to someone hosting a download for Windows orbiter as well as a Windows CE orbiter here: http://langstonball.com/linuxmce
(since the 0810 lmce doesn't have working download links, could someone edit the wiki to point to some official links to the Windows MSI and Windows CE CAB files please? I also found this one which seems to be just the Windows version: http://www.kbs.org.nz/downloads.html
Having installed the Orbiter_CeNet4_XScale.CAB from langstonball.com on my XDA running Windows Mobile 5, when I run the Pluto Orbiter I can see a screen showing a log window of the XDA trying to conenct to the router and I can see an empty slot for device ID and IP address, but nothing else happens and after a short time the XDA says it is out of storage memory (there's loads of space on the internal memory and the 2GB card I installed it on).
Am I using the wrong installer or is there something more to getting an orbiter working on a WinCE device? I have an old tablet PC that I could re-purpose if this was more likely to yield a result, but not sure which OS to put on it, Windows XP Tablet edition or some version of Windows CE?
