Hello Bill,
thanks for the pointers. The TC131 is indeed from Western Peripherals,
and I got the manual from bitsavers. It is a TM11/TU10 controller, so you
got that right too! I checked, it is set for CSR 772520 and vector 224.
I renamed the MS.SYS driver to MS.SAS and the MT.SAS to MT.SYS.
After rebooting I still get the same I/O errors, but ...
On the drive is a small thumbwheel switch to set the drive to device number
1, 2, 3, or 4. Funny, it can not be set to 0. That is partly visible, but
I do not want to use that much force that I damage the switch.
I tried all .DIR MT#: commands (where # is 1,2,3,4).
All give the same I/O error, and the tape stays at loadpoint.
I don't know how it happened, but I entered .DIR MT: ... the tape moves!
So, it seems that the drive number is irrelevant, even more: you must not
specify it on the RT11 commands! I have done several .COPY to MT:, and
they are all successful. A .DIR rewinds the tape and lists the saved files.
It seems that I have a working Kennedy 9100 (1600 bpi) ! Yippie :-)
thanks,
- Henk.

Onderwerp: Re: using the Kennedy tape drive under RT11
Does the tape drive emulate a TS11, TM11 or TM03/TU/TE drive.
It could be that the controller is mis strapped.
Who made the TC131? I've seen Western Peripherals and Emulex on som e of
the web ilstings.
I would think it's a TM10/TU10 controller... since I knew of one that was
used that way in my dec days. You may need to unload the MS driver.

Hi all,
I have connected the Kennedy 9100 open-reel tape drive to my 11/84.
The interface board is the TC131. It sits in a UNIBUS slot, and the 3
cables are wired to the tape drive. The NPR switch is set for that slot.
I can mount a tape and after pressing "LOAD", the tape is moved to
load point, after which I can by pushing a button set the drive on-line.
So far, so good.
When I boot RT11, I see (with .show dev) that MT at 172520 is installed
however, MS at 172522 is installed too!
Using RSX11 (show aco) it lists: MTA - CSR 172522.
That seems like a conflict to me: MTA (172522) and MT (172520), where
at 172522 would be MS ...?
As this is my first actual use of tapes, this is my first puzzle.
Next: suppose I mount any tape (contents unknown and irrelevant), which
commands could I execute?
I tried the following (excuse my stupidities) under RT-11:
.dir ms1: --> returns: ?MON-F-Dir I/O err - 011020
.init ms1: --> returns: ?MON-F-Dir I/O err - 014740
is this meaningfull to somebody? Should these commands execute correctly?
thanks!
