The floppy

Following the news that Sony is to stop making 3.25" floppies, I thought it the right moment to scan and post this picture of a real floppy.

As the label says this is an 8" floppy containing part - disk 17 of 18 - of pnx (a version of Unix) for the ICL PERQ. Note the disk capacity - 256 bytes!! (I hope that's not a misinterpretation on my part). I keep the floppy up in the attic, I've no idea whether it would still work as 8" floppy drives are a bit thin on the ground.

I don't think I have a big enough wall

..for this poster of the history of Unix. Looks very nice though!
