Open VMS System Mgt Guide Scripts Avail.

[william degnan]

I've uploaded the contents of the disk that accompanis the book "OpenVMS
System Management Guide" by Lawrence Baldwin here:

http://www.vintagecomputer.net/digital/OpenVMS/

Maybe your copy is missing the disk.  The disk contains scripts for version
5-->6 transition.

Does anyone know of any MULTINET script libraries?

Re: Panda Display USB support in klh10 working

[Mike Ross]

Well if you decide to produce it - as a kit of parts or a finished
product! - put me on the list; I'll take two or three of them. Email
me direct if you like.

There's a USB Panda display?

I bought two of the original parallel port Panda displays years ago.
Recently wasted a lot of time trying to get them to work. The Windows
diagnostic tool program works perfectly - sending patterns to lights
and running them. But try to use them with klh and they initialize
with a few random lights on when you start it and then never change at
any point until *hardware* power is cycled. Evidently there's
something screwy and the support for them was never actually
incorporated into klh and/or the final Panda TOPS-20 release.


One of the big limitations of the original Panda Display is that the 
parallel port is accessed through IO ports, not the operating system. 
Because of that, a USB-to-parallel converter will not work.  I also got 
one of the original displays.  By the time I built it up, I didn't have 
easy access to a real parallel port.  That's when I started to design a 
USB-based display.  The hardware and firmware is fairly simple.  The klh10 
side of it is more complicated.

PDP-12 Restoration at the RICM

[Michael Thompson]

As a final diagnostic on the PDP-12 we tried to run FOCAL-69, but it
started executing instructions in non existent memory. FOCAL initializes
lots of peripherals and then tries different instructions to determine what
processor it is running on. It executed what it thought was a TC01 DECtape
IOT, but DEC had recycled the 6762 instruction for the KF12 Automatic
Priority Interrupt controller. This caused the KF12 to execute a hardware
PUSH instruction to save the processor state and then jump into memory
field 2. Since we only have 8k of core it executed  instructions and
hung. Replacing the 6762 instruction at 4376 with a 7000 NOP let FOCAL
initialize and run OK.

Modern technology :)

Going OT for a moment here (sorry Jay) over xmas I was talking VCRs with my
Missus and went off searching for the very first one I used back in '83-ish,
a Ferguson Videostar. I was surprised to re-learn that the channel tuners on
that were all the 'spinning wheel' type. There was one on fleabay for 10ukp
but I wasn't allowed to bid.

Re: Unibus/Q-bus board layout (in CAD format(s))

[Vincent Slyngstad]

From: Mark Kahrs: Sunday, January 03, 2016 8:35 AM

I was wondering: Are there public CAD files (no, not the medieval
detective) for the Unibus/Q-bus fingers / board layout?


Not sure who or what the medieval detective is, but I've 
got the "dec-con" Eagle library available at 
http://www.so-much-stuff.com/pdp8/cad/cad.php
which has parts DOUBLE, QUAD, and HEX.  Those are in 
v4.11 format.  (I also have them in the v6.6 XML format 
here on my desktop if you need those, but Eagle should 
convert the file formats automatically.)

I have some layouts for Eagle CAD.  They're for version 5.  I'll be 
upgrading to 7.5 in a few weeks.
