I currently don't have time to update my website, but the latest ACAtune tool, which also supports the ACA1231, is available from the Vesalia website:
It should also work with the older cards, but doesn't do anything different, apart from some changed output. Not tested with ACA630-30, because I don't have that any more. New: The -help option is filled with life, and it can also be called with "?" (which is the more common standard with Amiga commandline tools).
