try an acurracy of about 15 t-states! the only problem with this is the
unknown timing of in f,(c); does someone want to test this?  (I'm unable to
link)

.org _asm_exec_ram

 call get
 ld a,r
 ld l,a
 sub a
 ld h,a
 jp $4a33

get:
 ld a,r
 or a
 jr nz,get
 ld a,%1111111        ;test bit 7
 out (1),a
 ld c,1
 nop
 nop
loop:
 in f,(c)                ;undoc
 jp nz,loop
 ret

.end
