ECS EPD30 Penbex OS ROM Dump

The Penbex OS ROM dump from an English language ECS EPD30 PDA. The EPD30 is a Palm IIIxe clone with Sony Memory Stick hardware that seems like it was never fitted to production versions. Penbex was shipped on a handful of devices mostly meant for the Asian market, and has almost completely vanished.

As such, this should run on any IIIx-like device with a 68EZ328. It also runs, somewhat incorrectly (buttons improperly mapped, backlight always on) on the Palm V(x).

This replaces the Palm SmallROM - risk of bricking. If attempting to use on a real device, make sure you know what you're doing, the consequences of failure, and how to recover.
