I'm curious about how the C64 IEEE-488 interfaces make disk
accesses faster.  Are these interfaces just "converters" from the
serial port to the 488 bus?  (If so, all the speedup would come from
faster disks, I assume.  The C64 kernel firmware would still handshake
the serial bus at the same speed as always;  only the wait-for-data
times would decrease.  Does that sound correct?)

If 488 interfaces are not hooked to the serial port, how *are* they
interfaced?  Wouldn't some new disk driver code have to be added to
the kernel before the interface could be used?

Thanks.  Obviously, I've never seen one of these converters.
