Has anybody got a DCV54 that they are using? I am trying to get one working with David Gasswein's mfm board and having no luck.
The controller is working fine with a standard floppy as an RX33, even boots the MicroVAX from it. But on-board diagnostics cannot format or even recognise the mfm board as a winchester. Just got the scope out today and found that the drive select lines are being terminated OK on the mfm board, bit the controller is not even dropping drive select. (Yes I have tried new cables) Problem is I don't have anything old enough to test the mfm boards with other than the Plessey controlelr! I'm thinking there must be some on-board config that I am missing on the controller. - It has never had a real mfm drive connected to it.
