The flash module in my 368 is a 512MB Apacer, Model Number AP-FM0512ALOC5-NJ
I found the following page on the Apacer site, with links to a slightly generic datasheet.
Interestingly, the data sheet says this module works at 3.3 or 5volts. This puzzles me, as other posts seem to indicate a voltage issue.
These are very similar to the modules used in HP thin clients.
