The info is on my site. I also did some measuring on the IEEE-signals.
The 3.3V is correct. But the ATN signal measured only 1.8V when (H). I know 
that this sounds absurd but I know what I saw. And I also know that the signal 
was in rest because I measured it while running a BASIC program enabling me to 
toggle every line by hand. Again, I know what I measured, but to be honest, I 
have my doubts.
