[comp.sys.apple2] Unidisk in a //

bchurch@oucsace.cs.OHIOU.EDU (Bob Church) (07/03/90)

I just read a reveiw of the AI internal hard drive for the //c in 
Apple // at work. It said that since the hard drive was read from
directly that it was much faster than the unidisk. Does anyone know
how they do this? Is there a special controller built into the drive
itself? Otherwise this would seem to imply that you could hook a Mac
3.5 drive directly to the internal drive port.(yes, it's there, you
just can't see it because it's internal. I've swapped connections in
the past so that my external drive was the boot drive but they were
both 5 1/4 drives at the time. I now have a Unidisk external. I'd like
to be able to boot from it without the 5 1/4 searching for a disk.
I'm afraid to try any more experimenting since letting the smoke out
of the logic board twice. Perhaps someone knows of a place that will 
modify my ROM for me. It would only require a few bytes changed but
I have no way to do it.
