[A83] Re: 83-Plus Assembly programming header
ROM calls need to use the macro bcall instead of just doing explicit calls.
Try:
yes:
ld a,1
bcall(_setxxop1)
bcall(_stox)
ret
And do the same for all the other ROM calls. Calls to subroutines within
your own program can use regular call, but all ROM calls need to use bcall.
