Hi Mark;

Dear Milton,My computer (a Mac Mini G4) has only 1, 1394a port. 

(Currently I have it Daisy

chained with a Lacie DVD burner). If when I`m able to afford it, I  

was to connect the Flea 2

camera to it and the IS camera (DBK 21A F04 AS) using one of PGR`s  

1394b hubs, would this

set-up work to your knowledge.

Yes it will. But you don't need a 1394B hub though and it's basically  

a waste of money as your computer only has 1394A. You can just buy a  

1394A hub and run both cameras off that, as PGR includes a 1394A to  

1394B cable for the Flea2 models.

However you can't run both cameras at full frame rate and full size  

video at the same time. There simply isn't enough band width to do  

so. Astro IIDC will tell you if there isn't enough band width if you  

run at too high a frame rate.

Darren Neuhaus from PGR is asking me whether I have the

option to install a 1394 card?

You can't do that in the Mac mini, iMac, Mac Book or Mac Book Air  

models.

This option is available only to PC`s isn`t it?

No. The Mac Pro desktops have PCI slots to install an additional card  

in it. And in the Mac Pro Laptops you can install a PC/34 card which  

is similar.

This is one of the reasons I prefer buying a Pro unit rather than the  

"other" ones. If I lose USB or FireWire or Networking I have  

expansion options to replace that functionality with an inexpensive  

3rd party PCI / PC/34 slot card. Other wise I replace the mother  

board of the other Mac, which Apple may or may not cover depending on  

warranty.
