I'm trying to get one of my 11-23's going and finally
got around to setting up a TU58 emulator. got it
to boot RT-11 and now trying to get a RX-02 working.
I have 3 controllers and 3 sets of RX-02's. All do the same
thing. The just seems to not be able to find track 1 or Home
or ??? The heads just keep going from home to maybe the
first tack and back. The heads do load and the system tries
quit a few times then pauses and tries again. It then errors
on drive failure or read error directory not found, size
function failed depends what I ask it to do. I have tried all
of the boards and drives. all or them seem to do the same
thing. I do not know how good the drives are but can't
believe there all bad.
I have recheck the switches in the RX-02 and the Jumpers on
the cards. Cleaned the drives. tried different disks.
Is there some kind of compatibility issue that i do not know
about. Or do I have 6 dead drives.
The system is a Micro PDP 11, 8 slot Rack mount, with
1 M8189 11-23+
1 M8067 KB 256k Memory
1 M8639 YA MFM rx50 controller
1 M8029 RX-02 controller
- in this order.
Everything else seems to work. I added the floppy card
but the rest is original.
