High tech sticks

I've found some nice curiosities from years gone by whilst tidying up piles of old computing equipment over the years. Boxes of still sealed 5.25" floppy disks complete with enough tokens to collect a free clock, if the offer hadn't expired 12 years earlier. A still sealed 1MB memory upgrade kit for a Mac Plus, which may have subsequently actually got fitted to a Mac Plus. Earlier I found a particularly obscure example of old computing technology:

Sun cotton buds

They look like something that might have been sold in a 1950s Chemist shop but flip the packet over and their actual origin is revealed

Yep, that's 100 genuine mint condition Sun Microsystems cotton swabs. Why would Sun sell cotton swabs? To use with Sun tape head cleaner of course

You can't see it in the photo but the swab part number on the cleaning fluid matches the part number of the swabs. Because obviously you couldn't just use any old bits of cotton on a stick with your Sun tape header cleaner.

I've no idea how old this stuff is or what kind of tapes drives it was for use with. Early BBC Micro era generic audio cassette tapes in a WH Smiths branded tape deck aside, the only tape storage systems I've ever used have been DDS 3/4 units where the heads were safely inside the box out of the reach of 6 inch sticks. Come to think of it I know where there is a pile of SCSI DDS3/4 drives and still sealed tapes.

    Those will be for use with SUN QIC (Quarter Inch Cartridge) tape drives from the 1980s. They held about 60MB per tape, as I recall. And you cleaned the heads by dipping a stick in the bottle of fluid and giving them a scrub:-)

    I probably left some sticks and fluid behind in Maths when I left…!

    I guess cleaning materials for 20 year old tape drives were small enough to be overlooked in the purge that took place before the Maths dept relocated from Gibbet Hill campus to central campus at the end of 2003!
