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.
Found the tape drive!
Johnny, which tool were you referring to? C by chance? Only have a SPARC for this.

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?
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).
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

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

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.

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.

Grounding issue sorted. Trying diagnostics.
Booting compuserve monitor complains about file not found. Could be on a disk I don't have.

Start with just 7 bits no parity. Try both one and two stop bits. Then move on from there.
7 bits no parity is something I ve never seen. I would start with 8 bits no parity, one stop bit unless it s 110 bps. 7 bits with parity, that does come up on a few occasions. But while I ve seen 8 and 5 and even 6 bit serial comms used, I can t think of any 7 bits in the wild.
Looking like it's some grounding issue somewhere. Waiting until someone with better eyes had physical access and can trace it out...due to no schematics unless Peter has some.
