At page A-6 3.4 are the absolute,x addressing cycles.
There is also a T3 cycle (always - not only at page boundarys) with
discarded read. But I measured this with my 6509 and had no dummy read!!!

Also interesting to read, that at 3.6 with sta indirect,y there is no carry
to the address highbyte and it needs always 6 cycles.
Is this an error in the manual?

At 2.7 the lda indirect,y has carry to the address-highbyte and has 5/6
cycles dependent of the page boundary.
