mod 000Ah.

2- where is the SPT in which module ?

number of SA_tracks * SPT ~ region_SIZE (from mod.000Bh) ===> SPT~ region_SIZE/ number of SA_tracks

if permanent ovl is active then SPT is taken from mem_table 0Dh

mod 000Ah is a part of ROM, so SPT is not required.

Its copy mod 0102h can be read from SA.
