According to the Archived version of the website, it only seems like 4.0.0 works with Handspring devices. It also seems like 3.5.3 is the highest OS supported on handspring devices. I'll have to try on Windows... Also, have any suggestions for software to make it useful? I'd love to use it as a remote for stuff, but the remote apps are all paid. Also, I got a GameBoy emulator for it that seems to work well. Idk what else I could use it for.
I've just checked my big box of Palm software: sorry, not a single PalmDesktop-version for Mac coming close to your needs...
Most of the software, especially that one with "Conduits" had been Windows-centric.
For the best experience I'd also recommend to run Palm Desktop from Win2k or WinXP in a VM.
Beyond WinXP it's starts to be a hassle to get PalmDesktop and Conduits work properly without help from 3rd-party software, so I started to sync all my legacy devices with WinXP/VMwareFusion.
I still have a couple of old devices: Centro, TX, m515, TRGpro, IIIx, IIIe, Pilot. To synch them all with the same ("my") Hotsync-User-name I have a separate corresponding Windows-user for each device.
Since iCal/Calendar-sync is close to impossible (and even the advanced synchronisation (PocketMirror, MissingSync had a lot of problems and restrictions) I left PalmDesktop for good in 2009, when I got my first MacBook and iPhone.
The most advanced Remote-Control software had been NoviiRemote (I didn't like it much).
If you think about the usefulness of PalmOS let's start with this scenario: trapped with the iPhone or any other smartphone in a "black spot" in the middle of nowhere - that's where PalmOS and iOS meet, when it comes to productivity software on a stand-alone handheld device.
That's the occasion, where PalmOS may show it's strong sides.
- Database-Software with Excel-Sync: SmartList2Go, HanDBase
- Office-Software: Docs2Go(v.6.x for PalmOS3.5.x) with native Excel/Word/PowerPoint-support (forget about graphics for Word/PPT without the Conduit)
- Text-Input and Memo-Database: MemoLeaf is my favourite with most advanced searching option.
- Outliner: Bonsai (Handheld-files only useful with conduit and after Sync), ThoughtManager (the Desktop-Client may read the outlines without sync - my favourite), ShadowPlan (no experience)
- Basic IrDA-printing (I bought my first 2nd-hand HP2200-Laser years ago for this purpose and I still keep a bunch of those as replacement for my office. They are cheap and close to indestructable...)
- TealPrint: jot down anything - I created 3d-pictures of future rooms in our new home ...
- CAD: there had been a very advance CAD program as well, which is no more available
- ebook Reader
- email: SnapperMail (I don't believe it will be working at all after all these years. The site is down, too)
- MindMaps/Outlines/Organigrams: Inspiration8 (with Windows and Mac-PPC Desktop-Application) good for fast "rapid fire" input on the handheld.
