Hi,
I've installed the recent release of 2.11bsd on my pdp11/73 and
recompiled the kernel to fit. But for some reason I can't resolve hosts
>from my /etc/hosts file now; only DNS names.. I'm not running BIND. Is
there a setting that will allow me to find /etc/hosts entries first and
then DNS in this operating system? I can't even resolve localhost!
thx

Hi all --
I'm restoring a Xerox Alto and I started going over the system's Diablo 30
drive. The heads are in bad shape; the bottom one is actually missing both
parts of the erase poles (so the black portion of the head no longer makes
a "t", it's just a black line). This means the head (in addition to not
being able to erase) also won't float due to the head having small cavities
in them. The upper head looks a little better but I'd love to find a set
of upper and lower heads if anyone has spares.
Then I get to learn how to align these things.
Thanks!

Lets have another go (but this time I have some pictures)
Decstation 5000/125 ? also houses a CD drive.
Two expansion storage boxes ? one has a tape drive and the other one has
a floppy drive.
Two very large and heavy RGB Digital monitors ? one has both Digital and
Sony branding on the back of it. I haven?t dug the other one out as its
in a corner and is dam heavy but it looks the same as the other one.
Box of spares (RAM, CPU's, HDDs etc.)
I?ve never powered it up ? it was a rescue ? I believe it was a server
in a TAFE college in Adelaide. This is all I got from the rescue bar the
box of spares. The original owner had tossed all the documentation and
software.
Please note that the stand is not included in my offer and its located
in south western Victoria (Australia).

Tai-Ho (Taiwan) was the OEM supplier for flyback transformers used by Apple in the early Macintosh computers (1984+).
Russell Industries (New York, USA) produced replacement flyback transformers for monitors and TVs, these appear on eBay and remaining TV repair supply houses.
As noted, while the circular pin-out is often standardized, the voltages need to be double-checked.

Subject: Replacing the Flyback Transformer From My VAXmate
I am about as certain as I can be that the flyback transformer from my
VAXmate monitor board has failed. I know this is probably impossible, but I
am wondering if there is a way to find a more modern equivalent? How
standardised are these things? I do see a lot that appear to have the same
circular arrangement of the pins.
The VAXmate one is a Tai-Ho TH-1802B and according the Technical Description
has a primary voltage of +28V and produces auxiliary voltages as follows:
+13.1kV @85uA max
+950V @200uA
+45V @75mA max
-100V @1.2mA

Does anyone have, or know of low level documentation for Evans &
Sutherland Picture System 2 hardware?
I walk past a PS-2 monitor all the time and some of us started talking
about bringing it back to life.? I'm not sure if more of the system
exists, but it might.? I plan to check.
I looked on bitsavers and there's nothing I could find on the picture
system.? Other E&S hardware, but not PS.
Anyone know if any systems still exist?? I'd have to think the CHM has
at least one.?? Back in the day they were sort of required for anyone
doing commercial animation (or at least, that's what I could
claim/recall but it was a long time ago)

Preferably OS/VS2 TCAM System Programmer's Guide TCAM Level 10. GC30-2051
but I think it is similar to OS/VS2 TCAM Programmer's Guide, GC30-2041.
I get a hit for the former one:
http://www.computinghistory.org.uk/det/9844/OS-VS-TCAM-Progarmmer-s-Guide-T…
But it is not online.
Any one has a scanned copy of this document? Anyone that has a copy that
they could scan, sell or lend so that I can scan it?

I had to repair the RAM board in my VS3200/KA650 again, so I took video
of the whole process (less about a whole day I lost troubleshooting a
trace I nicked).
Maybe some of you will find it interesting to watch.
