@@ -12,7 +12,7 @@ PaulaNet is a WiFi network adapter for the Amiga that uses the floppy disk port
 
 The Amiga's floppy port provides a 500kbps MFM bitstream driven by Paula's DMA engine. PaulaNet exploits this as a data channel:
 
-- A **Raspberry Pi Pico W** (or Pico 2W) sits between the Amiga's floppy port and the WiFi radio
+- A **Raspberry Pi Pico 2 W** (Original Pico W is not compatable) sits between the Amiga's floppy port and the WiFi radio
 - The Amiga sees PaulaNet as a standard floppy drive (eg DF1:)
 - Special tracks (76, 77 and 78) are used as command/data channels
 - The Pico handles WiFi via the onboard CYW43439 chip and forwards raw ethernet frames to and from the Amiga
