  Hi everyone,
 Can someone please help me find an RS232 serial interface converter for
 the 64?
 Cheers

  Good luck, they weren't too common.  You might have to bash together some
 1488-1489 chips and a 555 negative voltage circuit to get what you need. 
I remember there being a circuit for this in 'Electronics -- The Maplin 
Magazine' <mumble> years ago. IIRC, it was mostly discrete components, I 
don't remember there being any ICs. 

I can try to find the article, I should have it somewhere. I know I don't 
have the PCBm, though. 

This is a ciecuit to convert the bit-banged serial port on the user port 
connector to RS232 levels. I assume that's what you're looking for.
