    It is now displaying stuff on the screen but all garbled and it feels like the clock is running at the wrong speed.

    DEFINE OSC 32 '8mhz Clock (x4 = 32mhz) Note max speed is 64mhz..
    OSCCON = %01100010 'Internal 8 mhz Osc and stable
    OSCCON2 = %00000000
    OSCTUNE = %01000000 'Enable PLL 8mhz x 4 = 32mhz
    It should be running at 32mhz :?

    Apologies. Operator error.
    Just realised the 18F26K80 is not pin compatible with the 18F2680.
    It has extra power pins and requires extra decoupling caps blah blah..
    Never assume anything.. This explains why it wasn't working in my 18F2680 pcb...
