Hallo Bill,

> If I sent you a copy of this software, would it help?

I doubt this. But the problem wouldn't be the software but the hardware.
The IEEE drives have have an electronic gadget on board what I call the
ATN-trap. The moment the computer sends an ATN, the NRFD and NDAC lines
are pulled (L) telling the computer the drive isn't ready yet. This
gives the drive some air to find out that ATN has been activated and
pulling NRFD and NDAC (L) using software. Believe me, I know where I'm
talking about because I spent years on this item :(

If you want more details, please se:
