All,
I just purchased a DSD 880 (fixed drive + 8" floppy drive) together with a DEC PDP 11/23. All very clean and was working before shipping (prev owner used hard drive lots but did not know if floppy drive worked; it booted from fixed drive). Was professionally shipped (by UPS) and seemed to be well-done and undamaged at arrival. However, I am having drive issues. I might be something simple.
Both head and spindle were locked. I unlocked both. At power-on, after fan is on and some time I get an error code "06" which in the manual is written as basically a seek timeout. I used the hyperdiagnostic controls and seem to be able to get floppy drive to operate but not sure if everything works yet.
Some suspicious things:
1. when unit arrived a cable inside, from a board to the front display panel, was unplugged, as if the connector got disconnected during shipping. I reconnected it -- without it, the front panel was simply fully off.
2. after powering on the unit and some seconds past, I think I hear the floppy drive as being tried to be used and then immediately I get the "error code 06" and a LED on indicating problem with the Winchester (fixed drive). Seems a bit odd. Is it that it tries to move floppy disk, then immediately goes to fixed drive, which immediately fails and gives error code 06 (seek time out). I am not sure if I am hearing the drive spin.
I read above about the some dip switches that can alter the boot to use floppy? Could they have gotten moved by cables during shipping? Why does it try to move the floppy? Is this typical? I think I can see the "axis" of the motor that spins the fixed drive and I believe it is not spinning. Can the power to it be unplugged somewhere?
Suggestions?
