Tascam 424 To Tibook?, hardware set-up Options

[pdiddyod]

Hi,

Thanks in advance for any help!

I recently bought an Mbox to connect to my TiBook 667/30G/512RAM with Pro Tools 6 & OS X.
I had been using a Tascam Portastudio 424 mkII cassette multitrack.

1) Is there a way to connect my 424 (via the Mbox?) to use it as an external mixer with Pro Tolls 6? If so, is there even any benefit to doing that?

2) I also have a BBE264R sonic maximizer, a Korg DDD-1 drum amchine, and a Yamaha REV100 digital reverberator effects unit. Can I make effective of use of these units in the digital realm? If so, how would I connect them...?
I'm recording acoustic/elec. guitar, vocals, harmonica, some basic keyboard.

Thanks!
