I just got Panasonic JU-475-3EAF (5.25" 1.2 MB drive) and i can't get it to work. I've tried it on a 386 and on a clone XT.
On a 386 POST just freezes. No matter if drive is set to 360k or 1.2M from BIOS. LED does not flash. I tried it as a A drive without B drive present.
Clone XT does not freeze so i can boot to hard disk. The 1.2M drive cannot read DD disks but drive motor and LED does turn on. I don't know if the XT bios knows how to handle 1.2MB drives so i tried single mode jumper (1M). I don't know if it sets the drive to DD or HD but it didn't help. I did try the drive as A and as B drive but results were the same.
JU-475-3EAF is made for Hewlett Packard and the jumpers are not quite identical to JU-475-3. There is no OP jumper but there is PA before DA and PH/NH selection below PA. Other jumpers are the same as on JU-475-3.
Jumpers are configured like this:
MDB, MM, PH, DA, DS2 and TM.
