These are the ones I don't know:
Super-8 movies and cine film of all kinds.
Using jumpers to set IRQs.
Daisy chaining your SCSI devices and making sure they’ve all got a different ID.
NCSA Mosaic.
Concatenating and UUDecoding binaries from Usenet.
They are computer ones so I am not surprised that I don't know them. Can anyone tell me what these are (I would ask GA but I think he is too young)?
Also
Vacuum cleaners with bags in them. Vacuum cleaner bags are now seen as the the thing to use in vacuums now. The filters on bagless cleaners degrade over time and are expensive to replace. So now the bags are of the disposable sort.
