Integer BASIC leaves the D0 and D8 ROM sockets empty; Applesoft BASIC
fills all the ROM sockets. In Integer BASIC systems, D0 may be filled
with the Programmer's Aid #1 ROM.

The difference between 13-sector and 16-sector Disk ][ controllers is
the two ROMs on the card -- I believe the 13-sector ROMs are called
"P5" and "P6" while the 16-sector ROMs are called "P5A" and "P6A". I
can't remember whether the ICs are stamped with this however.
