The PDP-8/I.  The 8/I panel has indicators for the multiplier-quotient register 
(for the EAE), instruction and data fields, and the fully-decoded opcode.

AT&T Uverse IPv6 vs. Mac OS X 10.(old)

[Tapley, Mark]

(Apologies in advance to non-Apple users)

Mac folks,
Last week AT&T “upgraded” our Uverse service. All of our Macs running 
anything 10.6.8 or older quit working. 
Cure was to turn off IPv6: System Preferences -> Network -> Advanced -> 
TCP/IP -> iPv6 to “Off” instead of “Automatic”.

Symptoms were *very* widespread, and matched reasonably well to failing 
hard drive or failing memory - system freeze, spinning beach-ball forever, 
can’t read directory, etc. etc. etc.  On the G3, I rebooted in single-user mode 
and actually got part way through the output of “ps -aux” in one case before 
freezing. However it did respond to Ctl-C and would then do a “ps -a” no 
problem, just no “ps -aux”.  We were a bit silly, didn’t read our Uverse email, 
and didn’t test other systems before hooking more old systems into the network 
- which then didn’t work. We were panicing about viruses, pulling hair out, 
sacrificing goats ...

Systems affected were :

iMac G3 Mac OS X 10.4.11  - ethernet
PowerBook G4 Mac OS X 10.4.11 - wi-fi
iMac 2011 intel Mac OS X 10.6.8 - wi-fi

Apologies if this is a known bug, but it really puzzled us for a while 
because the effects were so systemic; I hope I can prevent anybody else from 
getting a nice new (needless) hard drive like the 2011 iMac did…

Closeup needed

[Rod Smallwood]

Hi Guys
Does anybody have an 8/i or 8/L?. I need a close up pic 
of the logo area to the top left of the panel.

In particular the address text under the logo.

The font looks like a made up one and I need to create it.

Thanks

PDP-8/E-F-M OEM price list on eBay

[Noel Chiappa]

Hey, all you PDP-8 people: there's a PDP-8/E-F-M OEM price list going on eBay,
not very much:

  http://www.ebay.com/itm/272187153709

I saw it go past once before, figured someone would notice and grab it, but I
guess not...

PDP11 M9301-Yx ROM dumps

[Noel Chiappa]

OK, so we already had a dump of the M9301-YA ROMs, but were (apparently)
missing the others?

So I fnally got one of my UNIBUS 11's running, and whipped up a small program
to dump the ROM contents, and now have the -YB, -YF and -YH ROMs dumped. I'm
in the process of disassembling them now.

(If anyone needs the contents in binary format, to blow new ROMs, let me know,
and I can probably produce them if you give me the details on the format you
need the data in.)

Does anyone have any of the others - YC, YD, YE and YJ?

If you're not up to dumping them, I can send you my small program (currently
in .LDA format, but I can convert it to a script - it is not very long at all
- for the console emulator in the M9301 series), which will do it - it
produces packed octal output, 8 words/line, so a very small output.

On old boxes where I keep Linux (Ubuntu 7.x) and older hardware for my vintage 
work, I logged in one day and experienced major remote network problems and 
freezes.  Granted this version of Ubuntu is running IPv6 code that is far from 
mature.

My initial detective work showed problems with the IPv6 DNS resolution.  I am 
also a Uverse customer. Disabling IPV6 was the cure.  I’ve done this on my Macs 
running  10.1x as well and the number of similar but less frequent problems now 
approaches zero.

Judging by Bill's photo it's at least similar to Eurostyle (Microgramma).  But 
back then a lot of companies drew their own, so you'd see something familiar 
looking but not quite exactly right.

PDP-11 M873 ROM card info?

[Noel Chiappa]

Does anyone know of _any_ information about this series of cards? They are
quad cards which seem to use two chips of the same types as the M9301 uses
four, with 128 words of memory. They thus must fit between the M792 diode ROM
card, and the M9301, in timing terms. However, search as I can, I don't seem
to be able to find anything on them. Known variants are the -YA, -YB and -YJ.

Hi Guys
 Thank you to every one who responded to my request for 
font pics.

I found the right one in short order.

Re: AT&T Uverse IPv6 vs. Mac OS X 10.6

[Jerry Kemp]

Just curious if something specifically is broken or non-fixable with the 10.6.8 
IPv6 stack?


I'm specifically wondering if you did any troubleshooting to resolve this?  Or 
if just disabling IPv6 was the quick'n'dirty answer?


I'm excited for IPv6, but many of my Apple devices I have held back at 10.6 as 
the number of features that Apple took away seem to increase exponentially after 
10.6.x.

It’s likely something broken in AT&T’s implementation - I have a G5 (10.5.8) 
with Comcast and native dual stack which works just fine.

OK, it turns out I needed to be looking for "BM873"; under that, it appears to
be fairly well documented (prints, TM, etc).

> Known variants are the -YA, -YB and -YJ.

Most of the later variants are for use on the 11/40 which is the front end of
a KL10; there's a PDP-10 document online (KL873.MEM) which lists them all in
some detail.


Does anyone have a -YB we can dump? (I have a -YA, and will dump that in a few
moments, here.)
