Unfortunately, most of Apple's technical notes following the Guide to the
Macintosh Family Hardware tend to be along the lines of "the EASC is an
enhanced version of the original ASC chip found in earlier Macintosh
models and maintains backwards compatibility with the ASC".

Needless to say, not all that useful :-(

Of course, you never know, it might actually document the SWIMII....

Later.
