Those are different than the ones I have in my cage. Marc, do you have
ones like mine, or Vince's? Again I've not seen the ones in the 600
chassis, so don't know if they are what Vince printed or not.
These are more like the ones that were used in most of the Microdata
1600 card cages. They used one piece ones like this, and ones with two
slotted guides / slot as well in those.
As I said in my reply the ones in the 400 card cage are the ones which
have the round blisters with two strips composing all the card guides on
each side, rather than one / slot.
