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)
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!
