AT&T 6300 Hard Disk

[Jeffrey J Wieland]

I want to replace the 10 meg Olivetti hard drive in our AT&T 6300 with
a 20 meg Miniscribe 3425.  The 3425 has 612 cylinders and 4 heads, like
the 20 meg Olivetti drive that AT&T apparently also used.  I need to
know how to set the dip switches on the DTC controller board so that
I can format the drive.  I think that the Hardware Reference Manual for
the 6300 has the settings, but we don't have one of those around here.
Thanks in advance.
