< That brings me to another question, can the ST506 controller speak
<RLL? I have a 122MB RLL drive laying around, I doubt it does, just thought
I think not but, the rll drive will run MFM. It will be about (80mb).
<I'd ask. RLL drives use ST506 and MFM use ST412, or am I backwards?
Ah, ST506 is a Shugart 5mb drive(6mb unformatted), ST412 is a Shugart 10mb
(guess what 12mb unformatted) drive that also has the same interface as a
ST506. So based on that the answer is: _yes_! Oh, and RLL drive are
basically MFM drives with tweeked RW electronics. In some cases they are
the same drive.
