Cassette Collection

My yesterday's Blip got me thinking ...... so I got out the USB Cassette Converter and plugged it into my computer.  Thwarted - the instruction book tells me I need software - and it only mentions Windows and I have a MacBook :-(  More research is needed.
No matter, this made me delve into my cassettes and one part I am particularly proud of is that, from Feb 1973 to May 1991 I recorded the BBC Top 20 on the 1st Sunday of every month!!  All the recordings are on these cassettes - so very, very nostalgic (and maybe a bit of Radio history).
