Walt,
The LL comes with a set of headphones which allows you to here the audio
via a headphone jack on the front of the drive. There are also audio jacks
on the back of the drive which allow you to hook up to external amps or
speakers. I'm not too much of a hardware techie so I'm not too sure about
the interrupts. I do know that the DMA and IRQ interrrupts are not set on
the interface card but you do have the option of setting them. The base
address is set to 340 Hex but you can change that if needed. The system
does come with on caddy.
