My girlfriend owns a PS2 55sx and I am trying to help her put a HD 
in it without paying IBM to much $$$$$$. I am coming in to this from 
a point of ignorance and because it is not my computer, I have not been
reading all the news so sorry if this has been dealt with before... 

Anyway, does what you are saying suggest that, although you have to stick 
the logic of and ESDI controller between the PS2 and an ESDI(controllerless
drive), could you somehow bypass the ESDI controller and stick a standard
IDE drive into a PS2?

Secondly, for there to be any relevance to my situation, does the PS2 55sx
use ESDI to control its 60MB (standard?) HD?

If not, is there any way to put an IDE drive into a PS2 55sx?

As an aside: is there anyway to put a Colorado Memory Systems Jumbo Tape
drive (which generally connects (I think) to a standard ISA floppy controller)
into the 55sx?
