Palm, Inc. and Handspring, Inc. have released updates to the Palm OS which fix a problem caused by faulty DRAM chips in some Palm Vx, IIIc, IIIxe, and Handspring Visor Deluxe handhelds (see "Tests & Fixes for Defective Palm DRAM" in TidBITS 537). The patch released by Palm now operates on Palm IIIxe devices; previously, a fix was available only for the Vx and IIIc models. You’ll need the serial number from the back of your device in order to download a testing application and (if your device is affected) the patch. A similar solution exists for owners of the IBM-branded WorkPad c3.
Handspring’s Updater V1.0.0 not only provides a solution to the DRAM problem, but also corrects bugs when launching the Calculator application and using a serial cradle when a Springboard modem is installed in the device. Handspring recommends that all Visor and Visor Deluxe owners apply the upgrade.
