Hallo allemaal,


This morning I discovered quite some emails in my emailbox all with from the
beginning of July. I remember Per mentioning a problem with the server so
that could be the reason.


Hallo Nick,


I already wondered why you didn't answer my email but now it seems it has
stuck somewhere.

I do.

I didn't know that. I already checked the keyboard once every thousand loops
but activating my ATN-trap only in this loop improved the situation about a
1000%.


> I think that's it.... some of its not elegant, but necessary.

As said before, CBM-HD is based on PC-DISK which was meant for the C64. And
there I hadn't these problems. I'm quite sure that the C64 is much much more
flexible regarding the timing of the transfers.
