Emax

Hello,

I'm going to be adding an internal zip drive to my Emax but I'm trying 
to decide how to go about the power supply.  The details are as follows:

I have an Emax rack and an Emax HD keyboard.  I swapped the Emax HD 
keyboard's boards with the Emax rack's in order to convert the rack 
into an HD version.  The change was a success but now I don't know if 
there is a difference between the Emax and Emax HD's power supply.

I have read in this forum that an internal zip drive will "burn out" a 
power supply and I'm also asuming that the Emax power supply has less 
capacity than the Emax HD's.  

I looked at the Emax HD's power supply and I was able to get these 
specifications:

C50.31E
p4.9.14/+5v/5a
p2.7.12/+12v/1.85a
p1.6.11/12v/0.34a
p3.8.13/dc com
-Max 40w

I also looked in the Emax's power supply, but there weren't any 
specifications like that.

As Does anybody know if the emax hd's power supply and the emax power 
supply are of equal capacity?  Does anybody have any recomendations on 
how to go about having an internal zip drive powered safely?  I'm 
looking for an internal zip drive so I can boot from it.

Thanks.
