Changes
The ROMs are allocated numbers from 0 to 1F. The firmware will only initialize ROMs from F to 0 at boot, so it completely ignores half of the available memory. To solve this problem, ROM slot F comes pre-programmed with a boot program that will initialize the 16 remaining ROMs, and also allows more control over them.
