Subject line says it all -- and I know this is a long shot. Anyone have
one going spare? Finally got my 5120 working (after scrounging a
keyboard, display, and an ROS board from a parts machine*) and of course
I had no idea that a terminator was required in order for the internal

Thanks as always,

(*stillneed a Command/Language ROS board since it turns out my 5120 had
not one but two bad ROS boards, but I've borrowed it from my 5110 for

Hi! The N8VEM SCSI to IDE/SD project has been renamed the S2I project.
There has been large progress of late and things are really shaping up. I
have distributed 3 of the 4 remaining prototype PCBs and have accumulated a
short list of hardware changes for the next PCB revision.
http://n8vem-sbc.pbworks.com/w/page/62549548/S2I%20Status
Thanks and have a nice day!

Technical bulletins state that yes the cabling for a second drive is
modified to accomidate for the system to power on the external drives by
means of a relay. If you didn't get the memo and you attached a second drive
you would be greeted by a resistor on the drive burning out. :)

30 years ago, at flip of a switch, the internet as we know it WAS BORN
How TCP/IP nearly fell at the first hurdle
By Gavin Clarke ? Get more from this author
Posted in Networks, 3rd January 2013 08:59?GMT
Thirty years ago this week
the modern internet became operational as the US military flipped the
switch on TCP/IP, but the move to the protocol stack was nearly killed
at birth.
The deadline was 1 January, 1983: after this, any of the Advanced
Research Projects Agency Network's (ARPANET) 400 hosts that were still
clinging to the existing, host-to-host Network Control Protocol (NCP)
were to be cut off.
The move to packet switching with TCP/IP was simultaneous and
co-ordinated with the community in the years before 1983. More than 15
government and university institutions from NASA AMES to Harvard
University used NCP on ARPANET.
With so many users, though, there was plenty of disagreement. The
deadline was ultimately set because everybody using ARPANET was
convinced of the need for wholesale change.
TCP/IP was the co-creation of Vint Cerf and Robert Kahn, who published their paper, A Protocol for Packet Network Interconnection in 1974.
ARPANET was the wide-area network sponsored by the US Defense
Advanced Research Projects Agency (DARPA) that went live in 1969, while
Cerf had been an ARPANET scientist at Stanford University. The military
had become interested in a common protocol as different networks and
systems using different protocols began to hook up to ARPANET and found
they couldn?t easily talk to each other,
Cerf, who today is vice-president and "chief internet evangelist" at
Google, announced the 30th anniversary of the TCP/IP switchover in an
official Google blog post titled "Marking the birth of the modern-day
Internet".
The 1983 deadline?s passing was anticlimactic, Cerf recalls,
considering how important TCP/IP became as an enabler for the internet. Cerf writes:
When the day came, it?s fair to say the main emotion was
relief, especially amongst those system administrators racing against
the clock. There were no grand celebrations?I can?t even find a
photograph. The only visible mementos were the ?I survived the TCP/IP
switchover? pins proudly worn by those who went through the ordeal!
>Yet, with hindsight, it?s obvious it was a momentous occasion. On
that day, the operational Internet was born. TCP/IP went on to be
embraced as an international standard, and now underpins the entire
Internet.
It was a significant moment, and without TCP/IP we wouldn?t have the internet as we know it.
But that wasn?t the end of the story, and three years later TCP/IP was in trouble as it suffered from severe congestion to the point of collapse.
TCP/IP had been adopted by the US military in 1980 following
successful tests across three separate networks, and when it went live
ARPANET was managing 400 nodes.
After the January 1983 switchover, though, so many computer users
were starting to connect to ARPANET - and across ARPANET to other
networks - that traffic had started to hit bottlenecks. By 1986 there
were 28,000 nodes chattering across ARPANET, causing congestion with
speeds dropping from 32Kbps to 40bps across relatively small distances.
It fell to TCP/IP contributor Van Jacobson, who?d spotted the
slowdown between his lab in Lawrence Berkeley National Laboratory and
the University of California at Berkeley ? just 400 yards and two IMP
hops apart ? to save TCP/IP and the operational internet.
Jacobson devised a congestion-avoidance algorithm to lower a
computer's network data transfer speed and settle on a stable but slower connection rather than blindly flooding the network with packets.
The algorithm allowed TCP/IP systems to process lots of requests in a more conservative fashion. The fix was first applied as a client-side
patch to PCs by sysadmins and then incorporated into the TCP/IP stack.
Jacobson went on to author the Congestion Avoidance and Control (SIGCOMM 88) paper (here) while the internet marched on to about one billion nodes.
And even this is not the end of the story. Years later, in an interview with The Reg, Jacobson reckoned TCP/IP faces another crisis - and, again, it's scalability.
This time, the problem is millions of users surfing towards the same
web destinations for the same content, such as a piece of news or video
footage on YouTube. Jacobson, a Xerox PARC research fellow and former
Cisco chief scientist, told us in 2010 about his work on Content-Centric Networking, a network architecture to cache content locally to avoid everybody
hitting exactly the same servers simultaneously. You can read more here. ?

The system has
M8189 cpu
M8067 memory 256k
M8029 RX02
M8061 RL02
M8639 HD controller
Everything works except the M8061. Jumpers are set to Factory default.
I did add the Q22 jumper just in case. There is always a chance its a bad
controller card.
The drive will come on line but that's about it. If I try to boot from it. i get
an
error, 'no controller' . If its running under RT11, booted off the RX02 , I get
'cant read directory '
Any words of wisdom out there

I had the same idea until I switched the drive ID from 0 to 1.
The BUSY light is now off and remains off on the drive until I tell DISKUTIL
that the drive I want to work with is on channel 1 and not channel 0, at
which point it probes for the drive (if it finds nothing it says the drive
is not ready and asks to specify another drive), the BUSY light comes on and
we get the same issue as before where it knows there's a drive but it can't
format and says the disk is bad. The light WILL go out if the system reset
is toggled which is probably because the controller is reset in the process.
The cabling is keyed on the edge connector side and pin 1 is noted on both
the ribbon cable and the header on the disk controller so there's no
probable chance the wiring is wrong.
I don't see why it could be trying to find an existing error map AFTER I
specify what the factory had printed on it. It would make more sense to
search for that BEFORE it prompted me to specify it.
(http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/CRW_778
9.jpg) It could be ignoring it like you said but there's no way to try with
a differently formatted disk at this time.
Unsure if WRITE PROTECT is stuck. Seagate's own papers don't even mention a
write protect jumper so I assume it simply does not exist for the drive.
(ftp://ftp.seagate.com/techsuppt/mfm/st225.txt)
I also don't see WRITE PROTECT listed as a pin on the ST506/412 interface
cabling.
According to this website
(http://nemesis.lonestar.org/computers/tandy/hardware/storage/mfm.html) I
finally managed to get hold of a Type 4 hard disk controller for the TRS-80
Model II/16/6000 family of computers (which looks like this:
http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/CRW_7791
.jpg)
Sourcing the external drive enclosures for Tandy systems is near impossible
unless you have a lot of spare money handy so I instead did some research
and mounted a Seagate ST-225 INSIDE the computer on a custom made mounting
bracket over the PSU.
(http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/100_276
9.jpg)
The drive is a known good drive and formats and boots under MS-DOS. In order
to run it under Xenix 1.03 I need to format it again using DISKUTIL. The
controller can see the drive and seems to know it's ready but the problem is
that the utility instantly fails the entire disk the moment you start the
format.
(http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/CRW_779
0.jpg)
Tried with other ST-412 interface drives (full height, half height and 3.5")
and they all do the exact same thing. Lonestar.org states that the '225
SHOULD be compatible with my controller. I looked up any documentation I
could find and I see nothing about any sort of configuration the controller
that needs to be set to support the drive. It should just plug in and work.
The only thing I seem to find odd is the BUSY light on the drive is stuck on
when the controller is attached which seems suspicious.
Anyone here got a slue how I should be tacking this problem?
Hi all,
This is one I've been working on for a bit without success, and I'm hoping
the community has some ideas to offer.
I'm attempting to recover the Lisa Xenix images on BitSavers so I can boot
up a Lisa for an exhibit. I've managed to get the images onto a Mac IIci
over the network (rather than through the dance of PC to Mac file
formats), but DiskCopy 4.2 doesn't recognize them. I used the boot.dc42
image on LisaEm and got it to boot as far as it will (Ray acknowledges in
the documents that Xenix doesn't work on LisaEm yet), but of course the
emulation is likely written to the image: still, it suggests the images
are likely OK.
I found information that suggested it was necessary to use an older Mac to
generate the correct disk format: I've formatted my 400K disks on a Mac
Plus under System 6.0.3, and run DC on that Mac, too. Still no joy.
Any suggestions? Thanks -- Ian
any stash of MODEM info? Bitsavers not much.... unless I am looking in
wrong places.
We have some we have accumulated set aside here waiting for the day
of a fast scanner but want to thin the stack if it has already been done
elsewhere.
cc me offlist also... I do not always read my digest file.

Since my name was mentioned...
There are plenty of differences. Virtual terminals for one. Which also
means that only M+ have batch queues. Named directories. Logical names.
Variable send/receive. Secondary pool. Split I/D space support.
Supervisor mode libraries. Accounting. Online reconfiguration. Mixed
massbuses (probably not that big win today, when people run simulators
anyway). Memory is managed slightly differently. I think that only M+
have disk shadowing and disk caching (also perhaps less used in emulated
systems).
Lots of tasks end up having more memory available in M+, which means
they can handle more data, or have more capabilities. This also affects
things like SYSGEN, which in M+ is rather more user friendly.
There are probably more things, if I think some more. But this gives a
fair idea. M+ is basically more.

Agree. 11M is fine. It's just that if you can run M+, I'd recommend it.
But it do require much more of the hardware.
It takes way more memory, and it requires certain features in the CPU,
that 11M do not.
11M can be run on basically any PDP-11, as long as you have atleast
about 56K of memory (Better with more, of course.)

I'm still digging. I found more 550 stuff. I think this is everything
that came with the 550. Here's a chance for you 550 owner's to get the
whole set at one shot!
Original DS-DOS box and invoice.
Original Sanyo Easywriter ver 1.3 disk
Original Sanyo disk box with 550 dos ver 2.11 and BASIC 1.25, two
original Sanyo disk for InfoStar (set B disk 2 and 3 of 4; disks 1 and 4
are below), original Sanyo disk for DOS 1.25 and BASIC ver 1.1
Original Sanyo disk box with all three original disk of set A, WordStar
and CalcStar and a backup copy of DS-DOS.
Two card board dummy disks used to protect the floppy drives duing shipment.

Howdy,
I'm looking for a source for a front bezel / plate / panel for a Sun
2/120. Anyone happen to know where I might be able to obtain one?
(I'd also be interested in the correct Mouse / Keyboard that goes with
the Sun 2 series)
I'm slowly working on restoring it, and the panel is the major missing
piece. (I just recently found a replacement power supply, so I hope
to be able to get it to boot shortly...)
Thanks.

Purely out of curiosity, is anyone aware of the possible existence
of LVD/SE SCSI (e.g. HD68) over UTP (RJ45) extenders? I'm aware
that one normally goes for FC, or a SCSI<=>FC bridge, but those
tend to be rather pricey.

This was software me my parents used in the 1980s on

Does anyone have this, willing to sell or --- more ideally,
for me --- willing to trade a SGI IP59 quad-processor CPU/node-
board? (P/N: 030-1989-003)
I have several (non-SGI) systems of interest, Alphas (PWS 500au's
and DS10s), but also Sun SPARCs (e.g. Ultra 10) and also at least
one HP Integrity rx2620 "Montecito" (largely maxed out, with 24
Gbytes RAM) to trade. All of the above are max'ed out, in terms
of 'specs' & configurations, plus there are many (PCI, PCI-X,
AGP, etc.) options available. I also have an IP53 dual-processor
CPU/node-board, as a possible 'replacement' (in case an IP59 board
would have to be removed from a working system) and may even have
a quad-processor one (i.e. the one I currently have installed).
I'd also like to emphasize, to avoid confusion, that these are
things I have to offer. Not so much things I'd like (or deem
sensible) to trade 1:1. The reason I'm looking for this part,
as well as other parts, is because I'm trying to get as much
out of my system as possible, as I'm working on my portfolio
as a graphic designer.
Either way, please don't hesitate to contact me. I'm open to
ideas and offers. Thanks in advance.
- MG
Does anyone have a complete set of SGI DMediaPro DM2/DM3 LVDS
cables, willing to trade/sell? (See my other WTT/WTB thread,
for the IP59 board, for possible items of interest to trade.)
I'm specifically looking for both a white (P/N: 018-0985-001)
and black (P/N: 018-0946-001) LVDS cable, to connect a DM3 to
a VBOB.

previous threads for possible items to trade.)
Thanks in advance.

Two Compaq AlphaServer DS10 systems, each with a 466 MHz EV6
processor and 2 Gbytes RAM (I can also reduce it to, say, 256
Mbytes). There are various options additionally, including SCSI
RAID (e.g. Smart Array 5300 or even Smart Array 6400), GbE
(DEGXA, original and/or modified), stock ELSA GLoria Synergy,
various Radeon 7500 (also All-In-Wonder), NEC USB, audio cards
and more. One of the two DS10s 'as-is', as it may have a faulty
CD-ROM drive (it's also missing its 'badge/name plate' with
"ALPHASERVER DS10" on it, below the "Compaq" logo, in case you
should care). The skins are all intact, in good/excellent shape
and included.
I have various options to offer. In any event, please contact
me for more information, offers or potential trades (I'm in
particular looking for SGI parts). I can also show pictures
and arrange a 'test drive' or 'tour' via SSH or Telnet.
The systems are located in the Netherlands and I'm willing
to ship (internationally).

Anyone interested in a barely used, mint-condition, HP AlphaServer
DS15? Equipped with a 1 GHz 21264C/EV68CB, maxed out with 4 Gbytes
RAM, (*original HP*, active-cooled, noise-free) ATi Radeon 7500,
(rare) DS15 audio option, DEGX2 (dual-port Gigabit Ethernet) and a
hot-swap front access disk cage (I may also be able to include two
disks and sleds, contact me about that). A nice touch, especially
for those used to the DS10, is that SCSI (KZPEA) is on-board.
Besides the on-board KZPEA, I also have a KZPDC (HP/Compaq Smart
Array 5300, Ultra160 SCSI RAID HBA) and/or KZPEC (HP Smart Array
6400, Ultra320 SCSI RAID HBA), as well as an HP/Neterion XFrame
10GbE NIC.
