I have a cassette unit which installed into a 5¼ drive bay on one of my PCs... it is controlled via the Com Port, and has software which automatically plays both sides of a cassette and converts them to WAV or MP3 format files.

It can make the whole cassette into one file, keep the two sides as separate files, or chop it into tracks (I prefer the manual approach...!).

The beauty of it is that it works unattended, so you don't have to watch it for an hour and a half whilst it rips that C90! I can insert a cassette, go off to work or something equally pointless, and come back to find I forgot to set the thing going...

A cheaper way to do it is to come out of the headphone socket on your Ghetto Blaster, and plug the other end of the lead into the Line In socket on the PC (usually coloured blue these days).

A stereo 3.5 jack to jack often comes with PC speakers or monitors with built in speakers these days - that's the cable you need - just ignore the fact that the plugs are green, or you'll go in the wrong 'ole... so to speak!!
