Hello, I have read some of your pstings at classiccmp.org. I got a HP 7958B drive of the trash (still working) and would like to get it running on an IEEE488 Interface. You wrote you got it so far to read/write sector this would help me alot. Also an interesting command would be to park the head before switching off. Maybe you know where to get some resources or you have something yourself. Thanks in advance, Michael
