The Fossil WristPDA has 8 megabytes of RAM – this was extremely much a few years ago(in the days of the Palm m5xx series, for example). However, the WristPDA does not support VFS – so, Palm OS applications that demand an SD or MMC card can not work on the WristPDA. Installing a RAM disk application doesnt work either, as the WristPDA lacks the Palm OS expansion manager – but Alexander Gratz and I managed to fix that up!

The first step involves installing the VFS manager from a Palm OS 4 PDA. Get the following files(for an english WristPDA), and install them:

  • Card Info.prc(optional)
  • Card Info_enUS.prc(optional)
  • ExpansionMgr.prc
  • ExpansionMgr_enUS.prc
  • FATFS.prc

Afterwards, you need a RAM Disk aplication. RAM Disk applications snatch up a bit of RAM, and then make the Palm OS believe this area of RAM is a memory stick or SD card. We decided to use RAM Disk from Handwatch, and it worked really well – the picture below shows Card Info running on the WristPDA:

The launcher supports launching programs from card, however, it does not support moving files over, etc. Use a freeware like FileZ to accomplish that, and all should be done!

  1. Hi Tam,
    I read about VFS over on the Yahoo Forum for the wristPDA and linked over to the article. Googled VFS and found out that it stood for Virtual File System. Googled card info.prc for down loading but couldn’t find it. A first for not finding something. Then I realized I readly didn’t understand what I was trying to do.

    Could you elaborate for the neophyte what these apps and the memory stick will do for me – what do I use for. If you would please, tell me in more detail where to find this stuff and its benefits.

    I have an AU5005 and works quite well although evry once in a while there is a bug. I have learned from the Yahoo forum how to do a lot of stuff like how to use hacks. For instance I use a font hack to increase the font size of the OS. I use a lot of HALs stuff and I fool aruound with an app called A5. Obviously, know one has solved the battery problem although every once in a while I consider Mike’s approach of an external battery. Anyway I wander. Can you help me with more information about your article so I can get started or at least consider it.

    Regards,
    Richard Locke

  3. Hi,
    first of all, no problem with the spelling.

    As for VFS; I basically explained most of it here:
    http://tamspalm.tamoggemon.com/2006/08/11/mysteries-of-palm-os-memory-part-two-sd-card-or-internal-ram/
    http://tamspalm.tamoggemon.com/2004/11/26/the-treo-650-sd-card-giveaway-mysteries-of-memory-explained/

    VFS alows you to store PC files on your PDA without conversion – for example, a Palm cannot keep a true JPG file in RAM without an app to convert it.

    Best regards and enjoy

  4. That Font hack sounds good. Where can we get it?
