    There are 2 reasons I would like to get it going on the 16F84. First its the most avaliable chip to me (can get them at my local electronics store), and secondly ive got a programmer for it. However, if need be i could modify the programmer to suit a different processor.

    Anyway, ive been through the code to get familiar with it, and changed anything that would be different for a 16F84 (i dont think i missed anything). When I compile I get these warnings:

    warning: unable to fit variable fsave in requested bank 16.
    warning: unable to fit variable t1 in requested bank 16.
    warning: unable to fit variable ssave in requested bank 16.
    warning: unable to fit variable wsave in requested bank 16.
    warning: unable to fit variable kbcnt in requested bank 16.
    warning: unable to fit variable kbcode in requested bank 16.
    warning: unable to fit variable kbindxi in requested bank 16.
    warning: unable to fit variable kbindxo in requested bank 16.
    warning: unable to fit variable kbbuf in requested bank 16.


    *edit* Was just reading the F84 data sheet and looks like it labels the banks Bank0 and Bank1, so I changed the BankA's to Bank0's and the warnings disapeared... Got a bunch of new errors now, so will have to look at whats happening with them
