About to dump a bunch of Compaq SCSI disk caddies (and disks)

Johan Helsingius wrote: I have a shoe box full of similar Compaq caddies, blanks and one or two slightly different caddies. I am interested in swapping what I have for SCA disk carrier plates which fit in the slots in the front of my DEC Alphaserver 800. These are a much simpler device consisting of a steel base with a honeycomb of ventilation holes, no top, clear plastic runners on the sides and a flexible clear plastic pull handle at the front. See figure 10-10 on page 240 of: http://vaxhaven.com/images/5/55/EK-ASV80-UG.B01.pdf I don't have any disks to include unless someone wants a couple of failed 18GB examples. (I also have an unidentified 4 slot SCA disk cage which I have no caddies/ carriers for and I have no idea what to look for except that they seem to be slightly larger (wider) than either the Compaq type or the Alphaserver 800 type.) I am in Dublin, Ireland. Regards, Peter Coghlan.
