I've had a couple or 3 3-1/2" RODIME drives
for quite some time. The
configuration 320 cyl, 4 Heads comes to mind for two of them, but I don't
remember the configuration of the other one.
The Kalok is 615 cylinders and 4 heads. It's currently
connected to a converter board, similar to the ones that Adaptec used
to make for connecting MFM drives up to various other interfaces.
