Well I've sourced a machine and will pick it up on Thursday. Original owner has never opened the case so it will be interesting to see which revision of the SID chip (6581) it will have.

Since my original post I have managed to obtain a job lot of Commodore and other 8 bit microchips. Apart from a large number of devices used in the Commodore PET, I now have 2 off 6581 Revision 4 SID chips. Not sure if they work as I'm unable to test but at least I'll have a spare!
