re: MBox and 233 Wallstreet G3 powerbooks. I have the same laptop and was trying to find out if I could use an MBOX via a USB cardbus, so was delighted to read your info. I do simple radio spot-type work too, but was wondering just how far you had pushed this setup. I have a SCSI accelerator in the other cardbus slot, hooked up to a Glyph 9GB. One other concern I had was whether the 16bit PT4.1 sessions I have from previous work will open and play with an MBOX and PT5.2, or would I face extensive bouncing of previous work? And also: can I digitally transfer from my 16bit SPDIF DAT output into the MBOX? Or only resample via analog? I'd appreciate very much any info... cheers
