<span style="font-family:arial,helvetica,sans-serif; font-size:12px">Hi,<br> <br> I've been working on this in the starting of the year and fixed this for XT based Janus.

Not<br> Amiga related but I have a Panasonic luggable PC compatible (with CRT)<br> that could benefit from some kind of XTIDE too.<br> <br> > Do you mean a 16-bit ISA card would work if I would get the XTIDE ROM<br> > loaded? Are they all 16-bit compatible of just some of them?<br> <br> Afaik that works. The IDE interface uses 8-bit communications for<br> everything except the actual data transfers, and CF cards can be set to<br> an 8-bit transfer mode. The result is that every second byte is lost on<br> a mechanical disk, while a CF card can be used directly.<br> <br> > > P.S. what other hardware does your A1000/A1060 setup have?
