Peter,
I have the drive imaged. Would you like me to send you a copy so you can help out? You know more about the disk structure than I do.
Still fighting with tape drive, though...

Getting that on there will be a bit of a challenge however.
The MRC's Panda distribution that runs under the KLH-10 emulator,
configure a tape drive to write to file. Make yourself a completek
boot/distribution tape. Write it to you SCSI tape drive, Johnny had a
program. Put the drive on the SC-40 and tell ot to boot from the tape.
...It's been too long since I've touched Panda. ;)

I know I'm doing something wrong to back up the monitor. ;)
Back to the manual!
I would do this with a copy of your boot-disk, as I don't remember how
the console processor file-system got there.. Think it's simular to
how it's done on a KS2020. (A file with the FE system and a pointer in
the home-block).

Found the tape drive!
Johnny, which tool were you referring to? C by chance? Only have a
SPARC for this.
Peter was referring to a bunch of tools that I wrote a *long* time ago, which allows me to copy files to/from physical tape drives under Unix.
They understand various tape image formats on disk, but it's easy to adopt to new variants as needed.
They are written in C, and are not complicated at all. I believe others have over the years written similar tools, so you should be able to find some somewhere.
Mine can be found at ftp://ftp.update.uu.se/pub/pdp11/tptools.tar. I hope they are in a somewhat understandable form. Documentation is close to non-existent, and they are not very forgiving to strange errors. :-)

Does the permissions system implement any special locking requiring me to drop to mini-EXEC from tape to backup the PS?
SCSI tape is identified with a response to SCSI INQUIRY (or is it INQUIRE?) correct? Does the NSP implement a command to list the devices on a specific SCSI channel? I THINK I boot from tape by setting source to the tape drive?

Yeah, obviously I'll be making a copy. ;)

The DIN connector is to control the bypass. CDDI is a RJ45 connector.
Ahhhhh.
(And 100M ended up using a very simular line encoding)
Thanks, that helps.
The DFxxx are KL10 cpu diagnostics, BIN are code for the chanel-cpu's
Glad I have diagnostics at least, if they are just KL10 diags there should
be a DEC reference of what diag = what.
Yes; xxKAA is the basic instruction test for a PDP10, DBKAA for
example runs on a KI10...
Thanks.
In you directory there is no operating system, it can still be on the
the disk in the OS file-system, but you need to teach the boot to look
at that drive..
Good thing EDDT works!
...no idea how to break back to NSP though...or anything about the
bootloader.

Thanks.
Do you have more than 1 drive?
No, my disk bays were empty.
Disk bay? Take another picture, please.
External CompuServe-manufactured enclosures. SCSI string with connectors, don't have the cable for connecting to distribution panel though.
As those are just 512-byte-sector ones I believe you said...those are easy
enough to image. I'd just need to give Gerry a ring so I can swing by
with a VAX or something that'll accept a SCSI drive.
Does the microcode/boot drive operate as a MASSBUS emulator, or is it also
SCSI brought out directly? (That one would POSSIBLY be documented
though...unlike the other stuff. So TOPS-20 could be made to work on
that)
Kindof... There are several operating modes, Standard T10, Standard
T20, 25 bit physical address T10, 30 Bit virtual adress Tops20.
That's very helpful, would be a good starting point.
Unless there is something special with the CS boxes, it will start off
pretending to be a normal KL10-B-E with masbuss..
Okay. Thanks for the info.
Put the Panda20 monitor on it ans se if it boots.
Getting that on there will be a bit of a challenge however.
Need to get a compatible tape drive so I can do anything real.
basically any SCSI tape works, a DLT, A DAT a 9trk....
That's easy enough to do then. Just need to find a working drive.

So you have a CDDI (fddi over copper) interface and 3 SCSI ports.

BOOT40.EXE tell me about hung SCSI devices (Shocker, none plugged in).
BTSCFC Can't find any channels
Can't tell if I'm missing a drive the rest of the OS would be on.
I think that "boot40" tells it to boot from chan4/drive0.
That makes sense.
