I am in the market for a known working ST419 MFM disk
System software forces me to the 306 Cyl / 6 Heads format (@ 32 256-byte
sectors )
Location : Switzerland .
This is a 85 milisecond MFM drive. I am sure that will figure into the
replacement.
A direct replacement might be the Tandon TM 503 or the IMI 5018,
Also the OTARI C 519, Disktron D-519, NPL 4191 are similar 6 platter drives.
The CMI CM 5619 is similar but slower at 105 ms.
The Hitachi DK 301-2 is a 3 1/2 inch version of the same, (6 HD, 306
cyl, 85 ms.)
