HP-86 MSUS error.



#2

I have an HP-86B. That's the one with the internal HPIB interface. When trying to access an HP9121 twin floppy disk unit I get the following error.
Error 120 : No MS Device.
The HP9121 works fine on an HP-85 system.
I've also tried a plug-in HPIB interface using the rear slots and still get the same error.
I think the internal 'dip' switches may have been changed in order to make the HP-86B a "Non-Controller" device.
Has anyone any internal switch settings or other suggestions.

Thanks in advance.
