Hallo, > The chips in the drive are 75160/75161, especially made for IEEE488 bus. > The data direction can be switched, so you need only one 8-bit port. > Sorry, don´t have much more info on them. 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. Groetjes, Ruud - This message was sent through the cbm-hackers mailing list.
