How to play music on an old music system ??

I was recently given an amplifier, a cassette deck and a pair of (huge) speakers by my dad, which he had bought way back in '84. Anyway, I thought that it would be cool to have a vintage music system and am therefore looking forward to setting it up. But the problem is that the system is almost 28 years old so I'm not sure whether the inputs/outputs on it will be compatible with the modern day audio connectors.

So basically what I'm asking is for a way to allow me to play music form my iPod on the aforementioned system.

I've given below the specs and photos relating to the cassette deck, amplifier and speakers.

P.S. - I'm new to this and am not familiar with the jargon, so it would be a big help if you guys could dumb down your answers for me.

Thanks.
