* The C64 tape loading is done through interrupts so is not intensive on the cpc. The CPC tape loading is intensive on the CPU.
- * The C64 communicates with the disc drive through a wired serial connection. This means loading from disc is slow unless a special loader is used.The CPC's disc interface uses a NEC765 disc controller and loads quickmuch quicker.* The C64 can easily play music while loading from tape or disc and do other graphical effects at the same time. The CPC can play music during tape or disc loading but it's more processor intensive and is restricted to no other effects when this is done.
* The CPC can do overscan (rupture or 32K screen method), the C64 can do it, but only sprites can be displayed where the border was.
