- He wasn't asking about the 1325.
-
- The RD54 is a Maxtor XT-2190. MFM recording, with ST506 interface. (Hint:
- MFM is an encoding method, not an interface spec!)
-
- The DEC versions are supposedly modified for lower start-up current and a
- quieter access mechanism (though mine, which has a DEC RD54 label, is certainly
- noisy enough :-). Other than that, they're identical and interchangeable with
- the Maxtor-labelled drives.
