6300 disk I/O, internal ROMs

[Rich Gopstein]

When I mentioned that I can't get better than a 5:1 interleave with my
WDXT-GEN controller, several people suggested that I use the internal
ATT ROMs to drive the controller.  I am a little confused about exactly
how that will work.

With my existing setup, I have set the 6300 to use the external (controller)
ROM.  If I switch it back to the external ROM, how do I set the disk type?

I believe that the (AT&T) DTC contoller had a set of switches to select
the type of disk, but I was never able to get a list of the supported disks
(for ROM 1.43).  I have a old full length DTC card that I could use to test.

Can the internal ROMs be used with controllers other than the DTC?  If so,
how do you tell the system what kind of disk you have?  (Mine is a st251-1).

Thanks.
