[cctalk] Re: Connecting MFM emulator as both 1st and 2nd drive in Microvax 2000?

Could y'all clarify for me, Do you mean "drive 3" and "drive 4" of drives 1-4, or 0-3? do you mean "DS2" and "DS3" of DS0-DS3, or DS1-DS4? On Sat, 12 Aug 2023, Nigel Johnson Ham via cctalk wrote: As far as i know, winchester drive selects have always been 1-4, at least in the DEC world!

As far as i know, winchester drive selects have always been 1-4, at least in the DEC world! Reference MP-02259-01 RQDX3 Field Maintenance print set.  Also Plessey DCV54 manual. I don't know about PCs- I went into teaching when the PC came out 'cos  there wasn't enough money in PCs!  I was

I have a Gesswein MFM emulator from decromancer.ca; who offer an adaptor that yields a 2nd MFM data connector. I'll use mine in a Microvax 2000. Does anyone know how to hook it up as two MFM drives in a Microvax 2000? The vendor sold a 1in high adaptor box, BA40A, with DD50 connectors to a
