Well, I wrote that in 2005 and was always intending to read the 
code...but too late! I just unpacked it today as I wanted to see if it 
could help me with a service dog and it is dead, dead, dead. The battery 
backup had failed...

Bummer.

Well, the designer turns out to be still around so I'll be calling him 
to ask if he still has the code and is willing to share it.

Have just posted the manuals to Flippers archive under Alpha 
Electronics...more to come after chatting with Bill.

So, try not to put off backing up data folks!
