Most clock cards don't follow a Pascal 1.1 protocol for their firmware.  Why?
Well, ProDOS 8 had a ThunderClock driver, and looked for non-Pascal ID bytes.
Combining those (listed in the P8 Manual) with the Pascal ID bytes would have
made for some pretty weird code (remember, this starts at $Cn00 and is usually
executed by BASIC programs to read the clock).

I have this information in a book, but it's at work and I'm at home.  If no
one has posted this within a day or two (like by Monday), please ask again
and I'll post it (since I'll be at work then, hopefully).
