TENLOD

[larsbrinkhoff]

SYSEN2; TENLOD 18
SYS; PDP10 DDT
SYS; PDP!0 RDDT

What is is? Probably not needed.

EDIT: It's for loading programs into the auxiliary processor. Also for debugging them, including remote debugging.

[larsbrinkhoff]

Some other similar programs:

• 10DMP - builds ok.
• DECDSK DMP109 - missing file DSKDMP SWITCH.
• MACDMP MOBY - undefined device codes, probably easy to fix.
• MACDMP RIM10 - syntax errors.
• MAGDMP - builds ok.
• MAGFRM - builds ok.
• TENDMP - builds ok.
• TENLOD - missing file JSF; STNDRD MACROS, and SYSENG; JSF MACROS doesn't seem to work. Also missing file 6STAP FILE.

CC @aap. Some of these have timestamps from the early 70s, and probably works on the PDP-6.

[larsbrinkhoff]

CC @aap again. Maybe PDP-6 software. Maybe DECtape.

CC @b4, our TENEX expert. Do you know what these are?

• TENLOD:

  THE SAME MANNER AS TENLOD, WITH WHICH

  without seeing the proper source, I can't speak for TENLOD.

• TENDMP and 10DMP are definitely TENEX, or at least derived.

• MAGDMP is potentially WAITS https://www.saildart.org/MAGDMP[S,SYS]1

• MACDMP is per your own posting...for DECtapes. Write 10DMP to disk tenex#1 (comment)

See below for a diff from TENEX I have laying around, my guess is one is disk bootstrap and the other is ... not.

TENDMP seems to be a later version of MACDMP, the title still calls it MACDMP. I would think it's just a version that (also) works with a PDP-10 DECtape controller.
See AI memo 83 and 118 for MACDMP. It was pre-ITS software to load and write from/to a MAC-formatted DECtape (see AI memo 82).

[larsbrinkhoff]

There's an ..INSRT 6STAP FILE. Can't see any file name looking like that.

[larsbrinkhoff]

AI memo 243:

By way of example, the EUTERPE binary file filename1 BIN would be loaded by typing the following to the timesharing DDT:

TENLODctrlK
L filename1_BINcr
F

The last command actually starts the DDT in the PDP-6 running.

[larsbrinkhoff]

The source file is truncated.

[larsbrinkhoff]

I think this program loads the auxilliary processor from the timesharing processor.

Given its name, it was probably first created to run on PDP-6 ITS, to load a program into the PDP-10 processor.

[larsbrinkhoff]

It's not truncated. There's just lots of extra text after "END BEG".

Got another copy: JSF; TENLOD 18.8.

AI memo 243 "Using the EUTERPE Music System" has some examples of how to use TENLOD.

Commands L and F are used to load a program into the PDP-6 and start it. PF starts it but also makes PDP-6 DDT talk to the user TTY.

[larsbrinkhoff]

TENLOD loads SYS: PDP10 DDT or PDP10 RDDT. RDDT is the remote debugger.
