Field notes

The homepage separates the Series 3 family, which runs SIBO (EPOC16), from the Series 5, 5mx, and 7 EPOC32 machines, warning that the software families are not interchangeable. It also gives model-level specifications, including screen resolution and processor details. The installation instructions name three transfer routes: CompactFlash card reader, PsiWin over serial, and infrared.
