I've got three Verbatim ST-600 "High Density Streamer Cassette" and five
Maxell CS-600HD "High density data cassette back coated 183m/600ft"
audio-cassette-like tapes with the notch on the back edge.  Most have data
written on them from around 1994 but one of each type is unused and still in
plastic wrapping.  Another of the Verbatim tapes is missing the box.

If they are of any use, they are available for postage from Ireland.
