First a few basics:

1.44 and 1.2 meg drives are very close brothers of different sizes.
They require the same signals and control leads.

The 6300 does not directly support this drive type

The 6300 Plus will

You must have MS-DOS3.2 (AT&T version) or a driver to let the drive work.

Now the details:
Western Digital does have an 8 bit controller for up to (4) 360k drive
or (2) 1.2/1.44m drives. It may provide full support for you.

There was a company that provided 5.25" drives with an adapter for 1.2
built into it. Weltec was the name, ask them for a 3.5" version.

1.44 drives write 720K just like 1.2m drives do 360K, use the same
warnings and provisions. It is possible though.
I have installed (2) 720K format drives and prefer the TOSHIBA drive
The second a TEAC, was a pain to install.

Hope this helps
