Here is a photo of a PDP 8/A 620 with the style of card guides that
Vince is referring to: (I think)

Different than the 8/A 400.
Here is a very clear photo of the card guides and cage for that beast.

   do you have
pictures? 
 Here is a photo of one of the sides of the 8/A (which I will have to
 try to straighten).  It is one of the strips of vertical bands with
 round card guides standing off for the cards to slide between.
 This is a 8/A 400 cage.  The larger 8A 600 and larger cage may have
 different guides.  A friend has one of those and I will get him to
 photograph it.

  I googled but get different guides.
 Are they small, like 5mm, and colored maroon or white?
 Those are also used in the 11/44 box and expansion boxes,
 I guess every BA11-K.
 The BA11-L has white hard"plastic" blocks some 2" long
 and has slits for 4 boards.
 So, a picture or description would be helpful.
