My Commodore 8250LP disk drive has an official kludgeboard in what seems 
to be a socket designed for an 6530. It contains a 6532, a ROM, and a 
simple TTL chip ('04 or something like that).

IIRC, though, the chip select levels of the 6530 were mask-programmable, 
so this might not work in all cases. And I don't think I can get any 
details of this to you by tomorrow anyway.
