Has anyone dissected one of the blue Iomega 25-way cables that are marked
"AutoDetect" at the female connector end?
I've got one in the junk pile and on a meter it checks out as though it's
wired with a 1:1 pin mapping, but I assume the "AutoDetect" label means
that it has some kind of smarts embedded into one end or the other (or
both) which only work their magic under certain conditions.
I'm on the hunt for a DB25 male connector and bit of multi-way cable so I
can wire up a null modem cable for the QX-10 [1] - if it's all at the
female end then that's good because I'd be lopping that end off anyway...
[1] which has a DB25 female RS232 port, and of course the only
gender-changers I have here are DE9s, no DB25's... :-)
cheers

Hi folks,
I have some duplicates (seven binders) regarding DEC's red/gray wall documentation:
- MicroPower/Pascal-RT, Volume 2, Version 1 Language Guide: System User's Guide (red binder)
Six gray binders (VMS 5.0):
- System Management Volume 1B: Setup
- Programming Volume 6A: File System
- Programming Volume 3: System Routines
- System Management Volume 2: ?Maintenance
- Programming Volume 1: Introduction
- Programming Volume 4A: System Services
?
I give them away for free, you take care about shipping costs. Located in Germany.
Contact me offline, if someone wants them. No need to take them as a bunch.
Kind regards,
Pierre

I had access to a bunch of VT100s, ADM5s and an occasional ADM3A. I also
didn't like the ADM3A because of its screen clearing difficulties. However, I
preferred using the ADM5s as I found them subjectively faster than the VT100s
(even after making sure smooth scroll was disabled). I never did any objective
testing but I put this down to the longer and more complex escape sequences
used by the VT100, especially when connecting to something that did a lot of
cursor positioning. As far as I recall, all would have been set to 4800 baud.

I have here an odd 7400 TTL chip - the prefix is TG. TG74S00J. Who was
this? Who made TG74xx TTL? It looks somewhat like an old Sylvania
ceramic DIP from the early 1970s. I have perhaps thought Transitron,
but it is not. And there is no logo, other than a plain looking T.
Ideas?

Top posting makes a lot of sense for people who want to read the gist of
what is being said now, instead of having to scroll.
Personally, I do both. But I don't mind the flame bait for people who
won't or can't see both sides of the issue. A good point was made about
voice synthesizers and top posting in another post.
I tend to equate sending messages to back in the 30 baud days ... less
is better unless needed for clarification.
And never let it be said I won't fan the flames ... especially when I
have a few minutes to spare :).
Hi
I've started a new N8VEM mailing list to discuss the SASI or SCSI-1 to IDE
and SD bridge board project.
The purpose of the mailing list is to discuss the design, build, and test of
the N8VEM SASI or SCSI-1 to IDE and SD bridge board.
It is a completely free and open source development to benefit all vintage,
hobbyist, classic, and home brew computer enthusiasts.

Just a quick update to let you guys know I finally got Kermit80 up
and running. Found MLOAD.COM and got it transferred over and used it
to link the kermit hex file and the Xerox 820 overlay. Played with it
a bit last night and hooked an old Hayes 14400 modem up to the comm
port and although I can set the command string(s) for the modem, it
doesn't hand control back to the terminal after it connects (was trying
to get it to connect to an old 80286 that has my TRI-BBS software on it)
I'll probably have to stick with transferring stuff back and forth with
Tera-term or something similar. There's kind of a grey area with Kermit
on just how much control it has over the machine's comm port (varies from
one machine to another), so maybe I'm trying to run data through it
faster than what the port will allow.
I need to get with Chuck Guzis at some point and get a license for 22disk,
just not right this minute, until I get this months bills caught up. :P
Thank you Chuck, and everyone else for your help.

You guys are going to get a good laugh out of this...
I got desperate and did a little measuring and eyeballing on the index
sensors on my 8" drive, and then took one of my prized DSDD Fujifilm
guaranteed 100% error-free disks, and carefully opened it up and even
more carefully slid the disk out onto a clean sheet of paper. I then
took a 1/4" drill bit and heated the back side till it was almost
red hot and shoved it through the jacket around where the other sensor
was located. Cleaned up the excess plastic with a razor blade and
smoothed everything up and carefully re-inserted the disk. Covered up
the other sensor hole and tried it out. Oops! Hole was about 3/16"
too low. Carefully slide the disk back out and notched the hole out a
bit. Re-assemble disk and tried it again. Ahaa! Drive now sees disc.
Formatted with 22disk using the XER5 SSDD setting and wrote 2 hex files
to it. Shut down PC, hooked everything back up, and miracle of miracles,
the Xerox actually read the files and let me copy them to the hard disk!!
Now all I need to do is get MLOAD.COM loaded on it so I can combine the
2 hex files (kermit & the Xerox overlay) and theoretically, it should
load and run. But it's been a very long day, and I just now found MLOAD
on my Walnut Creek CD, so something to do tomorrow.
So, the theory is correct, the 2 sensors DO designate between single &
double sided disks... (for future reference) :-)

Whatsoever a man soweth, that shall he also reap...The truth is always simple.
I am trying to get DECnet working on SIMH running VMS 3.7 using a DELUA. I
have already fixed one bug in the DELUA emulation that gave a fatal
controller error on startup, but now I get this:
$ @startnet
%RUN-S-PROC_ID, identification of created process is 00020011 %OPCOM,
25-JAN-2013 22:15:27.94, message from user DECNET DECnet starting
%RUN-S-PROC_ID, identification of created process is 0001000C %NCP-I-
NMLRSP, listener response - Operation failure, detail # 30 Executor
node = 9
(VMS037) %SYSTEM-F-ABORT, abort $
Can anyone tell me what this means?
After that the line bounces up and down with line synchronisation lost
errors.

Always wondered the same. Longer worded its floppy diskette. Not sure if it would ever be discette in eu? Alternatively discoteque (*sp) I believe is music or cd store in spanish. I'm not sure what disc (in compact disc) is short for if anything.
I'm restoring a pdp11/34a, and I've got a weird problem I'm hoping
someone out there can help me with.
The system seems to be working just fine, with one exception: bus reset
just doesn't work.
The unibus is configured correctly; I've verified that NPR is
jumpered/granted correctly through the bus. This is a BA11-L box with
the DD11-PK 9-slot backplane, configured like this:
Slot 1 - CPU
Slot 2 - CPU
Slot 3 - A/B M9312 bootstrap/terminator, C/D/E/F M7859 front panel
programmers interface controller
Slot 4 - 128 Kword MOS memory
Slot 5 - RL11 controller
Slot 6 - C/D/E/F M7856 DL11-W console RS232 interface
Slot 7 - C/D G7273 dual bus grant
Slot 8 - C/D G7273 dual bus grant
Slot 9 - A/B M9302 terminator, C/D/E/F M7856 DL11-W configured at 776500
for TU58 tape drive
The symptoms:
At poweron, the system starts the M9312 console emulator software; I
can use it to deposit a small program into memory with no problem.
Attempting to use the "S" command to actually start the program causes
the RUN light to come on; the program never executes, hitting CTRL/HALT
on the front panel causes BUS ERR, the RUN light stays on, and the only
way to regain control of the system is power off. For example:
@ L 1000
@ D 000777
@ L 1000
@ S
fails as described above.
If I use the front panel to install a program and run it, when I push
CTRL/START, the system halts at the start address. For example:
CTRL/HALT
CLR
1000
LAD
CLR
777
DEP
CLR
1000
LAD
CTRL/START
the system halts, run light out, at address 1000. If I then press
CTRL/CONT, the RUN and SR DISP lights come on, and everything works
perfectly. I can CTRL/HALT the system, continue, etc. With no problem.
Furthermore, if the program I enter contains a RESET instruction
(000005), the behavior of the system as it executes that instruction is
pretty much exactly like using the "S" command from the console emulator
- RUN stays on, CTRL/HALT causes BUS ERR, and the system is
non-responsive until I power the beast off.
For example:
CTRL/HALT
CLR
1000
LAD
CLR
240
DEP
DEP
DEP
CLR
5
DEP
CLR
1000
LAD
CTRL/START (the system halts at address 1000)
CTRL/HALT (single steps to location 1002 correctly)
CTRL/HALT (single steps to location 1004 correctly)
CTRL/HALT (single steps to location 1006 correctly)
CTRL/HALT (RUN light comes on, CTRL/HALT causes BUS ERR with RUN, system
is no longer responsive, have to poweroff)
My reading of the unibus tech manuals indicates that there is no ACK of
any kind for BUS INIT, so I am somewhat confused.
There _is_ a bit of noise on the +5V power supply; a voltmeter shows
5.02 volts stable, but there is a .5V spike at 50 kHz showing on the
scope; I can't see this causing problems _only_ with BUS RESET.
I have also verified that CTRL/INIT from the front panel seems to do
nothing at all. For example, if I halt the system and press a key on
the console emulator, examining 777560 shows 000200 (which is correct,
there is a character available at 777562). Pressing CTRL/INIT on the
front panel does _not_ clear 777560 - it still shows 000200.
All the 11/34a M9312 diagnostics run fine. This problem seems to be
limited to attempts at RESET. A disassembly of the M9312 console
emulator code shows that two things happen when you use the "S" command:
000005 (RESET)
followed by a
JMP (R5)
It's the RESET that drives the machine nuts.
Anyone have an idea?

Hi,
I have a working PDP 11/83 in a Pedestal (desk side) type case. Its fitted with a reasonable
sized Hard Drive, tape drive and 5.25" floppy disk. I think it has ethernet, but need to check.
This is in good shape, and boots. Its the larger desk side case (not sure on the case name)
so there is room for a second hard drive.
These are nice, 'office friendly' versions of the PDP 11, and quite a bit easier than the UNIBUS
machines to manage.
Email me if interested. I can get full specs and pictures if there is any interest.
Thanks
Ian.

A different issue is someone like me who replies via phone sometimes. This dingleberry phone doesn't allow me to edit original text, just delete it or include it. Sucks and I often wait to be at a real computer before replying. Still top posting intent is to not have to scroll through or past original contents. Perhaps its lazy or managerial thinking.
