This is not hardcoded. The base is taken from the VR (vector register
$fffa17), which happens to be initalized to $48 by TOS ($40 for the base, $08
for software EOI). Similar for the TT-MFP, where it is initialized to $58.
Multiplied by 4, that results in vectors $100-$140 for the MFP, and $140-$180
for the TT-MFP.
But i think this is already handled somewhere.
