Monitors for ADM3 and ADM3a parts or replacement whole unit?

[Ed via cctalk]

Monitors  for ADM3  and ADM3a parts  or replacement whole unit?
 
 
Have  a beauty  that was just  given us   but  there is much of the monitor 
circuitry missing.. the  picture tube  is  there  the flyback transformer 
is there.
 
But the rest of the monitor...  GONE!  
 
Assuming the  logic  and keyboard  work   where  can I get the  rest  to 
make the monitor whole again?
Or.. do I just  leave it as a static  display next to another  static  
display  early system?
 
It is  a beauty  save for  the missing monitor   parts..
Advice Hints?
 
thanks   Ed#
 
 
 
 

Best place to get info on monitor repair...

[Warner Losh via cctalk]

Had a static discharge event with my VR-201 and suddenly the background is
'grey' rather than 'black'. By this I mean I see maybe 50% of the color
(where before I saw maybe 1%) and maybe half a dozen solid diagonal lines.
This replicates across the two rainbows I tried the monitor with.

This seems like it would be a common thing, but my google fu has turned up
little. I get why I might not find a how-to on fixing a VR-201 (though I do
have the prints), you'd think that I'd be able to locate the proper jargon
to find the answers, but so far goose-eggs. I can't even find a good
monitor repair FAQ, though I guess I need a primer on terminology as
well... I've done a lot with video over the years. But it's all been
digital, I've never repaired analog gear.

The VR-201 has a AC-coupled RS-170-like signal (rather than the standard DC
coupled). Supposedly, this is one capacitor away from being RS-170. So the
backup plan is to run the signal into NTSC->VGA adapter. It would be nice
to fix the monitor that I have though...

What's the right terms to search for when looking for the components to
replace to fix this issue? I have the prints, but analog circuits have been
a weakness in my EE fu for many years.

This made a tiny difference. …up changed the ifconfig report to (from memory):

en0: flags=8863 

(including RUNNING) while …down changed it to:

en0: flags=8863 

(no RUNNING flag).  However no ping, and the connect light on the hub still 
depended exclusively on manually setting rate to 10T/UTX (lit) or anything else 
(not lit).

It did help, sort of. I kind of wish networking were less arcane, though I’m 
sure there are good reasons it’s the way it is.

the inet6 lines are not on the G4 ifconfig report - this seems good, since IPv6 
is turned off.  Else it looks pretty similar if not identical. Also it looks I 
think identical to the ifconfig report from my G4, with the exception that the 
G4 has an en1: (corresponding to the wifi card, I think) section.

After some surfing, I also tried: ipconfig getifaddr en0 
That produced a message ending  '...failed, (os/kern) failure"

I looked at system logs. There are version numbers there for a lot of things  
but I forgot to write most of them down (and I’m back at the office and the 
machine is at home). The one I did preserve was:

Console log: 
Server 3f07 in bootstrap 1103 uid 0: "/usr/sbin/lookupd"[43]: exited 
abnormally: Hangup.

I’ll have another go tonight and will do some web-surfing for more clues today.

Also have not taken time to find OS9 boot CD. I’m hoping I can configure a USB 
drive as OS9 boot, move it to the PowerBookG4 to download firmware update, move 
back to G3, launch, update, then re-boot from internal hard drive. Is this 
feasible?

> Have you tried a different hub?

 

I did, and this took some time. First test was unplug the ethernet 
cable from the G3 and plug it into G4, no other change. G4 ran internet 
normally, so I think hub, modem upstream, etc. are likely to be OK. I also 
tried cross-connecting G3 to G4, but no ping either way to the manually 
configured iP’s on both machines. I forgot to try AppleTalk networking while 
cross-connected, but I’m not sanguine about it working.

Next test was remove Asante EtherHub 10T/8 and replace with 2Wire DSL 
cable-modem, intending to use its internal 4-port ethernet hub.  The cable from 
the wall to the Asante had been plugged into its unique crossover port (port 1 
has a straight-through and a crossover, so  the Hub can be used to extend 
another hub conveniently without using a crossover cable). Therefore, when I 
plugged in the 2Wire, I changed to use a crossover cable from the wall to 
duplicate that effect. 

Lots of blinking lights ensued. I’m theorizing the 2Wire and my AT 
Uverse cable modem were having a heated discussion about something, over either 
ethernet directly or possibly Wi-Fi then gated to ethernet. The G4, now plugged 
into the 2Wire, could eventually access the 2Wire configuration web-page but it 
was very slow and there were many dropped connections (according to TenFourFox, 
my web browser). I did finally successfully reset the 2Wire password, and used 
my Cellphone with ConnectBot to log into the G4 via: (wifi) ->  AT -> 
(ethernet? I think not wifi?) -> 2Wire -> (ethernet) -> G4. That also was very 
slow, but I think it showed most of the connections were live. 

Testing the G3 showed the exact same behavior as before. The (rapidly 
blinking) connection light on the 2Wire hub was illuminated only when ethernet 
rate on the G3 was manually set to 10T/UTX. No pings in or out, even when both 
G4 and G3 were set to manual iP addresses and I pinged those addresses (and the 
addresses were in the range normally assigned by DHCP). The complaint was 
usually “no route to…” . Also no ping from the G3 to the LaserJet 4M+ on the 
same (2Wire) hub, although the LJ4M+ did respond to ping from the G4.

At this point, a call of: “Dad, did you do something to the internet?” 
put a halt to further experimentation. “Um….”  
“…um no, why? Maybe if you try again? :-)” 

Only about 15 minutes later, after plugging the printer straight into 
the wall (cutting all hubs and the G3 out of the circuit and shutting off the 
2Wire WiFi) did service go back to normal. See above about arcane networking….

I’m reasonably convinced the hub, modem, cabling, etc. are all working 
and the fault is on the G3. I 

Re: Help identifying UNIBUS PDP-11 CPU upgrade

[Josh Dersch via cctalk]

And to reply to my own post, tonight I took a closer look at the boards and
noted that someone had written "3" and "4" on the CPU and memory board
handles in sharpie.  I checked out the power and ground signals on the card
edges and they match up with a typical MUD slot.  Based on this I felt it
safe to assume that these go in slots 3 and 4 of the 11/34's CPU backplane
(the first two SPC/MUD slots).

I pulled the 11/34 CPU boards in slots 1 and 2, the M7859 and bootstrap
boards from slot 3 and installed the upgrade boards in slots 3 and 4.  Ran
the front panel cable to the connector on the CPU board and powered it up.
 "7" appears on the LED panel and if I hit the "HLT/SS" button I get an ODT
prompt!  The BOOT button causes the RUN light to momentarily flash, but
that's about it.  Not sure what else can be done with the front panel, if
anything, would be nice to find a manual.

At any rate, I've successfully booted 2.11BSD on the upgraded 11/34, and it
seems to work well.  If anyone out there knows more about this boardset,
let me know...

Thanks,
Josh

BBS INDEX w/110 baud phone #'s and HP2000 Phx Union HS System Console HOME!

[Ed via cctalk]

BBS INDEX with110 baud phone #'s and the HP2000   Phx Union HS System 
Console   comes  back to PHX AZ  this  month! 
 
 
BBS phones!   -  how about  one   that  is  dial up? that  will answer  at 
110 baud  so I can use my  ASR 35 that  just came  home after 30 plus  
years?   this ASR 35  Teletype was the console for Phoenix Union high  School's 
 
HP-2000A  timeshare  system in the late  60s and  stayed on the system   
throughout   2000F   upgrade. 
 
The 2000F config was still using a  2116 processor!  We got  the  2000F  
systems and   put in a  2100 processor  upgraded it to 2000 ACCESS and resold 
it but kept the teletype   around  but  sold it to a fried in calif that 
wanted a  cheap  printer.  so away the teletype  went 
 
I still had the  2116 HP  computer I had  saved   soe  gave that to SMECC  
for the museum  display. 
 
Now the Teletype   that was the console can rejoin it!
 
The Phx  Union  2000A  orig. had  2116, 16 port mux, a  drum and a asr 35 
console.
 
Now  a  ASR 35  is a wonderful memory for me even before  that as I had one 
 with a GE Diginet TDM 114  modem as my first   terminal. wish I  used to   
access the Maricopa  Community  College  2000f  which is the one  we  
bought and   ran  even before we  got the Phx  Union  one.  (   we  still have 
the  Maricopa College  system  under  glass  here at  SMECC  but  need the GE 
terminet with  HP paint job (Sherman... where is one?)
and  the  2883  disc  for it.
 
Now back to the  ASR 35!  We need the   following... ( already  checked the 
usual  teletype  places)

1- Plastic  dome on the top  of the teletype..
 
2- the cover plate that  fits an ASR 35 paper tape  reader.
 
3 - A clean set of real printed manuals  and schematic  drawings ( Yea I 
have the download)
 
4 -  A working  TDM 114  GE Diginet modem 
 
5 -  A list of 110 bad  dial ups... does telenet or tymnet  still exist ?  
will int answer at 110 baud?  what  will?   ok  how about  some BBS ssytems 
that  will answer at 110  baud?
 
Thanks in advance for any  advice, parts, info  etc...
