while cleaning the head with a "cotton bud" and IPA I had an idea ;-)
As a quick and dirty solution, but honestly working, I took a cotton bud and used it as a felt button.
And with this, I am getting RPMs, meassurements in IMD align test and I am able to load a DOS formatted 8" disk and open a textfile
so everything is pretty fine - the potentiometer I adjusted to the same levels as on the other drive which seems to be fine.
IN the next upcomming days I will think about 3d printing this button and adding afterwards some felt onto it.
So finally I have 2 working 8" drives at home
both can access the A drive under dos and write data to it - the next big step is to boot from an 8" floppy.
But I think I would need a real dos system and not Freedos or could I also create a boot disk from there?
Since I have a SS,SD floppy and my BIOS assumes a 1.2MB drive, when I create the boot floppy I need to tell the system (similar to sys a
that the floppy is half the "wrong" known size.
How to do this?
