Booting DOS/360 give file not found. Tracing indicates that the file is being deleted.

Systems Concepts disk controller, used on MIT-AI.

This is quite optional. The RP10 controller works well.

Noel Chiappa wants to work with us to document the DL10 in this page:
http://gunkies.org/wiki/DL10

I'm opening a separate issue for this.

I seem to have this working, but I'm not sure how to best implement it.

There's a failure doing the final DUMP in the ITS build. The error message is Improper thread context for operation and then the simulator dies. Full log in https://travis-ci.org/PDP-10/its/jobs/350579354

I'll look into this, but I'm also posting it here in case you have any idea what it can be.

Hi
I'm trying to run 9AP on I7090 but fails on booting.
May be I'm doing something wrong?

Many thanks in advance
Best regards

Add support for IMP-10. Used by TENEX.

Maybe needed to use 340 display in ITS timesharing. I'll have to check in detail.

Can probably stub out most functionality, because there's no PDP-6 attached.

Occasionally, I see the SYSTEM CLOBBERED message.

I'd like to understand exactly what it means. And then, how to detect what is doing the clobbering.

Pressing Ctrl/E in CANDE sometimes causes the B5500 to go into a busy loop.

The problem can reliably be reproduced as follows:

• Add SET CPU1 ENABLED to xiii.ini.
• Start B5500 simulator, TSS/MCP XIII.
• Enter DT and TR at SPO.
• Enter CE to start CANDE.
• Telnet to port 2000, login as USER1.
• Enter LIST LOG/DISK command.
• While QUIKLST is running, press Ctrl/E. Repeat Ctrl/E a few times if necessary.
• Eventually MCP stops responding and CPU goes to 100%.
• killall -QUIT b5500 to produce core dump (copy attached).

This does not occur when CPU1 is disabled.

I am running latest B5500 on Slackware 14.2 on Intel Core i7 laptop.

core.zip

Allowed attaching 8 PDP-11s for I/O. It's probably not well documented.

Used for:

• Chaosnet (see #17)
• Knight TV system (see PDP-10/its#279)
• XGP printer

Shortly after booting ITS, there's the message

TOP LEVEL INTERRUPT 200 DETACHED JOB # 3, USR:TARAKA CNAVRL 

Running FED using the 340 display will cause ITS to crash.

During the course of running FED, where will be an interrupt from the 340. PIH is set to 10 (level 4).

When the interrupt service routine returns through LPBKRT, PIH has changed to 12. When LPBKRT+1 executes a JEN, PIH is set to 2. But check_irq_level will not trigger a new interrupt request on level 1 because PIH is already 2, and it remains at 2 when ITS returns to user mode. The next time user mode calls a UUO, ITS notices PIH is 2, and throws the message "UUO WITH PI IN PROGRESS".

I know KL10 and DTE isn't in the plan. I'll just post this here, and when you've seen it you can close it.

;;; Here is how a DTE works, as far as I can tell.  Each processor has an area
;;; which only it is theoretically allowed to write in.  This area is refered
;;; to as the OWNER'S area.  This area is composed of an section which is for
;;; the owner's use only.  This contains the keepalive count, among other
;;; things.  Next comes various sections in which the OWNER writes to SEND
;;; INFORMATION TO other processors.  These other processors must know to look
;;; at it.  When an 11 does an DTE EXAMINE operation, it is relative to his
;;; header word in the entire communications region.  So to examine the header
;;; word, location 0 is examined.  When an 11 does a DTE DEPOSIT operation, it
;;; is relative to the base of the area that it OWNs, NOT the base of the
;;; communications region.

;;; Well folks, that is correct.  The code now works following the above
;;; guidlines.  I wish it were documented in some DEC manual...

Some old software, include MIDAS itself, won't assemble with the latest ITS MIDAS 458.

I'd like to have a set of old MIDAS versions all the way to 108 which is the oldest known version.

Have you seen this document about the MIT pager?
https://github.com/PDP-10/its/blob/master/doc/ITS_Hardware_Memo_2.pdf
Hopefully ITS can again run on a KA with that pager implemented.

I built and dumped a new TECO. However, there's a problem when I start it. This message is printed over and over:

ERROR WHILE ENTERING ERROR HANDLER! POPPING TO TOP LEVEL.

To reproduce:

• :midas sysbin;_.teco.; teco >
• :job teco
• :load sysbin; teco bin
• purify$g
• press Enter to save in .TECO.; TECPUR 1212
• :kill
• :link sys; ts teco, .teco.; tecpur >

RH devices need to be assigned in order FS, RP, then TU devices. If the device is disabled the numbers need to slide down.

As of 9c151f9.

Steps to repeat:

1. make ka10
2. Start ka10
3. Enter set cpu 512k
4. Segmentation fault

I tried to ^N over a system call, but the job didn't stop.

I'll prepare a test case with regular instructions, skips, jumps, calls, and system calls. I'll run it on both KS and KA and compare the results.

General cleanup on the LPR device needs to be done.

Starry-eyed wish item.

This info might be necessary to handle ITS DF10 correctly:

MIT-ML and MIT-DM (also KA's) had 18-bit DF10's with a special kludge modification (disabled with a toggle switch for running DEC diagnostics) to take extra address bits from the complement of some high-order bits of the count. The complementation is so that with a small count (which is negative) you address the low-order memory, for compatibility.

Last time I tried this, it didn't work.

Steps to reproduce:

1. Start simulator with the usual configuration for ITS
2. Attach magdmp.tap to mta0.
3. b mta0

OS/360 gets stuck in a SVC loop.

When building EMACS, some essential libraries are first generated from TECO sources. This is done with the EINIT library. It should be run from EMACS with M-X Run Library$EINIT$? Generate. However, this elicits the message

LIB     FILE NOT IN LIBRARY FORMAT?

This message comes from EMACS1; USRCOM 514 file; Load Library function. Of course, it's TECO code, so it's nearly impossible to decipher.

I dumped out the EMACS; EINIT :EJ file from ITS, and confirmed that it's identical to the one in the its repository. So there's no corruption.

TM10A hangs ITS.

This should be an issue with @philbudne's 340 emulator.

If I boot DSKDMP and start e.g. the standalone @ TECO available in the ITS . directory, the simulator crashes with a segfault. Gdb says this happens in XkbSetDetectableAutoRepeat.

If I set dpy disable, this doesn't happen.

In order to have multiple devices use PI channel 1, the AI Lab KA10s had a multiplexing feature.

MIT-AI had seveal deivces share channel1: TM10A, DECtape, IMP input, and IMP output.

It's documented here:
https://github.com/PDP-10/its/blob/master/doc/ITS_Hardware_Memo_1.pdf

As the ITS build times keep increasing, I'm starting to eye simulator performance. Is it appropriate to look for optimizations?

This isn't with a version from your repository, so feel free to ignore this until you have incorporated @philbudne's 340 CONI fix and I have tested against that.

There's a crash using the FED program in ITS. FED calls .DSTART to display some graphics in the 340 display. But there's a monitor crash.

My test goes like this:

• Load ITS (one with 340 support)
• SRECYC$B (340 interrupt handler)
• $G to start ITS.
• Login and start FED.
• Give it a font file name. (I have fonts.)
• The SRECYC breakpoint triggers.
• UEXIT$B (exit to user mode)
• $P
• The UEXIT breakpoint triggers.
• UEXIT wants to JRST 2,@XUUOH. XUUOH is 310000,,001125.
• UUOH0$B, which is the instruction right after UEXIT.
• $P
• The UUOH0 breakpoint triggers.

Attempting to set a breakpoint in a MIDAS pure page doesn't work. No error message. DDT doesn't make the page impure. Starting MIDAS doesn't trigger the breakpoint.

If you want to implement PDP-6 devices. ITS can use the old PDP-6 DECtape device.

There's DC 200, and UTC/UTS 210, 214.

CC @aap

I think this is a real-time clock. Without it, ITS will complain it doesn't know that time it is during boot.

When I start COMPLR, there's no _ prompt:

*:complr

LISP COMPILER 2155 [in LISP 2154]

If I press Enter, there's an error message and the prompt is displayed:

INCORRECT COMMAND SYNTAX - MAKLAP
_

Now I should be able to compile Lisp files, but the program doesn't seem to be doing anything after entering the command line:

_liblsp;_libdoc;tty

It's still possible to enter text.

PEEK works with the light pen, but the Y coordinate seems slightly off. To test this, start PEEK and type D to get the directory view. Then use the light pen to select a directory to list. When I do this, the wrong directory is viewed.

CC @philbudne

Opening an issue to log my attempts to use DECtape in ITS.

Since microtapes are hardwarily and softwarily unreliable on the ITS systems, their use is discouraged.

.INFO.; DDT 33

Here's a riddle. What happens if you put PUSH in location 0 and then execute it?

The answer is that it writes a new PUSH 0,0 instruction to location 1, and then executes that. Now it's more interesting, because it writes PUSH 0,1(1) to location 2.

And so on, but when it hits location 20, it breaks. If I single step this in timesharing DDT, location 20 gets 0. If I single step in SIMH, it gets 000000000022. The correct value ought to be PUSH 0,17(17).

I have started on an automated build of KA ITS and all programs.

I have encountered a problem shortly after purification. The first two programs built are MIDAS and DDT. They are first assembled with MIDAS, and then loaded into DDT for running the PURIFY routine. Shortly after this, ITS starts to act weirdly. It hangs; sometimes it's possible to get its attention by typing ^G, sometimes not.

I set :tctyp vt52 expecting a nice EMACS experience (also set xterm to VT52 mode).

But ESC characters come out as 377. Here's a session hexdump:
