Ran across this on Ebay tonight:
http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1649083427
This transformer has a 115V primary, and several taps on the secondary
ranging from 5 to 850 volts. What kind of device might require such a wide
range of voltages?
BTW (for those without 'net access) the device sold for USD103.50 and there
were no details as to what this thing was used in. This leads me to
believe that it's a high failure-rate component in a relatively expensive
(and not uncommon) piece of gear.
Any clues?

Hello, all:
I'm having a bit of a time with SNMP on my Windows NT box. I'm running the
Compaq management agents which use ports 161 and 162. But, when the SNMP
service starts, it complains that another program is grabbing the port.
Using "netstat -an" tells me that something is grabbing the ports using both
TCP and UDP. The TCP address shown is 0.0.0.0.
I have no other obvious programs running that would be an SNMP server. Is
there a utility that can tell me which executable is grabbing a given port?

Hi everyone
Looking for a source of AMD Am2901 bit slice chips ?
Try Dial Electronics at http//www.dialelec.com.
They specialise in obsolete parts, have no minimum order charge,
you don't need an account and they will also ship worldwide.
I've got a busted CPU board to fix so I've got a few 2901s on order.
If I can't fix the damn thing I will probably end up building a bit-slice

Greetings, all!
System in Question: AT&T 6300
I have two of these systems and was going through them, taking the best parts
of the one and putting them in the other to build out a good machine. I
happened upon a difference between the two that I can't figure out what I've
stumbled upon.
The keyboard controller for the 6300 is either an 8041 or 8741 chip, as
defined by the service manual. The one machine has an 8041A chip, so that's
normal.
The other machine doesn't have a chip at all. Instead, it has a piggyback
card in that slot where the IC is supposed to be. The piggyback card has a
chip on it that LOOKS to be a 88414 chip. I'll write below all the relevant
numbers on the card.
There is a wire that goes from the board around to the topside of the logic
board as well. Not sure where it connects, I haven't pulled the logic board
completely up yet.
Anyone have an idea of what this might be and if so, documentation and/or
description of benefits?
Thanks for your help!
Tarsi

List of Relevant Numbers:
- On the main chip, it has 88414 plus a adhesive tag that someone had written
on it "PDBD".
- The board itself is stamped: 491230 Z MI293 NA 6/84 (the last the date, I
presume) Also on the board is: MI293 COD.49199P-E-E4
- Yet another chip has the number: TMS7000NL-2

Good thing too as most of the surplus parts were off spec... I was burned

At least three vendors have most of the TTL line, JDR being one.
I might add that in '73 I did a TTL design, finding many of the chips
that

I've never heard "one-of" before, only "one off" (and "2 off", "3 off",

That uses a cheat that's built in to Intel print servers. As Iggy says, the
print server listens to all the packets that go past, and infers its IP
address from the address contained in the first ICMP packet it sees which
contains its own MAC address. It's not the normal way of doing it at all,
and it's not reverse-ARP, which Lawrence said the printer used.
It's worth a try, though, since it would only take a few moments to test.
And the Calcomp web page does say "make an entry in the ARP table".

Thanks, Lawrence. I've had a quick look at the URL you posted in your
followup, and it seems to me that unless Arno's printer (plotter? I can't
remember either) is bust, that procedure is what he needs.
I was about to reply to Arno's post, and was thinking about (R)ARP while
having my dinner. It's a bit odd the way it says to "make an entry in the
ARP table" because that's NOT what you do, exactly. The ARP table on a
host has nothing to do with providing responses to other things that need
information in order to boot, it's just used to map MAC addresses (Ethernet
addresses, typically) to IP addresses when talking to other hosts known by
IP address. But I'm sure it's just a case of Calcomp getting the
terminolgy slightly wrong.
What it obviously (to me!) means is to set up a host on the same subnet
(actually in the same collision domain) which will respond to a RARP
request. The way you do *that* on a Unix host is to make an entry in
/etc/ethers, containing a line with the hostname that matches the MAC
address you want to provide the IP address to. Then you also need an entry
in the /etc/hosts file, to map the hostname to the IP address. Finally,
make sure the rarpd daemon is running. Usually it will be started by a
line in one of the startup files in /etc/rc.local, /etc/rc.net, /etc/rc.2
or similar place (it's in the /etc/init.d/network script in SysV UNIX).
For Arno, this means:
create /etc/ethers if it doesn't exist
append a line with printer name and MAC (Ethernet) address
/etc/hosts must already exist for the Sun to work, so append a line for the
printer
start up rarpd if it's not already running
(the order in which you do these shouldn't matter)
If we call the printer "calcomp", the line in /etc/ethers is:
00:C0:E2:00:0C:8E calcomp
and the line in /etc/hosts is
111.1.0.1 calcomp
and the command to start rarpd is probably
/usr/etc/rarpd
or
/sbin/rarpd
possibly followed by '-l' and the name of a logfile in which to record what
it does, and/or the name of the interface on which to listen (le0, for
Arno's Sun).

OK, as the IP Adress of the SUN 1+ is 111.0.0.14 and the Subnet Mask
ff:00:00:00 (says so at boot):
ping -s 111.255.255.255
(if everything on the network is powered up and the PC is configured for
TCP/IP transfer) gets answers from:
hombre (111.0.0.14);the sending machine itself
papa (111.0.0.23);the SUN SPARCstation 2 on the next desk
? (111.0.0.83);a PC I've finally set up for sniffing
Nothing however from the printer. :-(

No idea whether that helps, but if both the SUN 1+ and the printer are
powered up, an arp -a shows:
pa3 111.1.0.1 at (incomplete)
and out of 25 packets I sniffed (Man, am I high now ;-)), 20 were ETHER type
0806 (ARP), the remaining 5 were type 0800. See also section "Configuring
the 971" (Ethernet adapter card of the printer).

OK, as I didn't finde snoop on the Suns (and didn't want to fiddle with
compiling programs by myself at this stage...), I set up a PC with a network
card, packet drivers and EtherLoad 2.00. Connected this to the idle transceiver,
started with -r (record traffic), powered up one SUN and recorded the first
10 packets from it, then powered up the printer and recorded until I had 25
(the printer had then finished its warmup cycle and was displaying "READY").
Got only packets sent by the SUN (MAC: 08.00.20.09.BC.D7) destined for
FF.FF.FF.FF.FF.FF (everybody?).
The sniffer's HEX output file decodes to a lot of unreadable characters if
interpreted as ASCII; only in the second packet that appears after switching
the SUN on, the host name 'hombre' is readable.
Decoding the whole data to decimal numbers show up the SUN's IP adress in
all packets, the address the printer should have in the eighth and every
following packet.
Is there a DOS based sniffer out there which will produce output as
understandable as snoop?
If not, and if anybody wants a go at making sense out of the output, I'll
mail the files private (HEX and decimal 6kB each, data ASCII decoded 2kB)...

No such menu item or anything related to Ethernet. AFAICFO (as far as I
could find out, adding to the current acronymania...) on the Internet, this is
the procedure for configuring the Ethernet adaptor used in this printer:
#Configuring the 971
#
#Connect the network cable to the appropriate connector.
#
#The following tasks are accomplished by the system administrator:
#-Make an entry in the ARP table
#-Telnet to port 2002
#-Configure the 971 in accordance with your operating system's requirements
#
#The 971 queue is 'raw'.
#
#Refer to Model 971 Network Interface User's Guide P/N M0016-490 and CalComp
Ethernet Software #Guide P/N M0062-240 for information pertaining to your
specific UNIX configuration.
#
#Refer to CalComp Model 971 Ethernet Hardware Guide P/N 501987 for
additional information.
However, with us there is no sys admin - so how can we 'accomplish these
tasks'?
I couldn't find the 'refer to' titles on the web - anybody knowing if/where
they're out there, or having them & willing to scan them for me? Any help
would be much appreciated.

The printer manual tells that test printing is invoked by a long press on
the key PRINT FONTS/TEST after switching the printer OFF LINE. Out comes a page
which does tell absolutely nothing about network settings. It must however
also be possible to print out these settings because in the paperwork, we
found a page which reads as follows:

Thanks for the tip; will give it a try now that you've reassured me.
I don't think it's the battery since the config is stable, i.e. the
power can be off for a weekend and everything's still fine when it's
powered up again, just that annoying F1 request, and the problem started
when I removed that modem and had to change IRQ's. I was reluctant to
pull the battery & reset the config in case that really messed things
up; at least now it's bootable. But sounds like it can't hurt to replace
the battery, so might as well while I'm at it.

The 74189 is inverting, though adding an external inverting buffer is NBD.
If y

That was late 60s very early 70s design. By late 70s microcode was common
or at least state machines. The availability of bit slices by the early
70s influenced
this greatly.

So what do you do? Plug it into every computer where it would fit? That could

So, to get to the point, is there any software out there which might identify

In my TI databook, they're both ALU and/or Function Generators (a rose
by any other name :), identical except for the carry/overflow logic.
Hope that makes both of you happy.
Allison (and sorry for not noticing that you're the exception, gender-
wise, Sellam's feminine side notwithstanding), I ran across a thread
here last year where you mentioned the Signetics 3000KT8080SK bit-slice
board; don't suppose you did ever find any documentation? I've got one
here that's pretty useless except as a source of TTL chips, since it's
all socketed.

Really, my TI databooks have it as the lookahead carry generator for the 381
ALU.

It's just a way of explicitly stating what the broadcast address for that
interface is. In every legitimate case I can think of, it should be
redundant if you provide the netmask (or the netmask is redundant if you
give the broadcast address). I'm not sure what happens if they don't
match. Maybe that's allowed if you have multiple IP addresses (ip aliases)
for the same physical interface, then perhaps you could use a "broader"
broadcast address to listen to more than one subnet on the same interface.
I don't know.

You were about right then, I think! I wasn't having a dig at you! Merely
"thinking out loud" and pointing out (in case Arno, for example, didn't see
the implications) that there are rather a lot of addresses :-)
Even then, it might not work. The range of network addresses from
224.0.0.0 to 239.255.255.255 are used for multicast, and no ordinary IP
software uses those for unicast (normal) or broadcast traffic. Above that,
I don;t know of any allocated uses, and things aren't suposed to respond to
them at all, which would be a problem if the setting are corrupt in such a
way as to fall in that range.

Ah yes but, the CMOS ram would cause one problem for the

Is "pa3" the printer name? What that means is that the Sun's Ethernet
software "knows" that "pa3" means IP address 111.1.0.1, but nothing has
responded to any attempt to communicate with that IP address, so it doesn't
know its hardware address. On an Ethernet, as you probably know, the data
packet is wrapped in several layers of what you might think of as
envelopes.
The outermost one contains the MAC addresses of sender and intended
recipient, and is what is always used for the delivery of the packet to the
next (which may be the final) destination en route.
So for "hombre" to know how to send a packet to "pa3", it first looks up
pa3's IP address (in etc/hosts, or using DNS), and then broadcasts an ARP
(Address Resolution Protocol) packet (sender: hombre's MAC address;
destination: Ethernet broadcast address, FF:FF:FF:FF:FF:FF) containing that
IP address as data. Whoever owns that IP address is supposed to respond
with an ARP reply (same packet type, different flags inside, with sender:
pa3's MAC address; destination: hombre's MAC address). Thus hombre learns
pa3's MAC address, which it stores in it's ARP table, and uses to send a
packet (the one it originally wanted to send) to pa3's MAC address.
> and out of 25 packets I sniffed (Man, am I high now ;-)), 20 were ETHER
type

Without knowing what was in the packet headers, I can't say what they were.
But probably the ARP packets were hombre repeatedly broadcasting an ARP
request to get pa3's MAC address.

snoop is only available as a binary, from Sun themselves (or from SGI, for
the IRIX version). tcpdump and other similar programs are available as
freeware with source. tcpdump needs a library called libpcap, whicxh is
also used by other decoders/analysers, such as Ethereal.

Probably ARP requests. FF.FF.FF.FF.FF.FF is the broadcast address
(destination, in this case). The next layer in the packet would tell you
what IP address it was ARPing for. BTW, Ethernet addresses are normally
represented with colons (':') separating the octets, not spaces or periods.

Yes, they won't mean much in that form. The format of an ARP packet is:
hardware type code (2 octets), protocol type code (2 octets), hex 06 (the
hardware address length, assuming Ethernet), hex 04 (the IP address length,
assuming Ethernet), opcode flags (16 bits giving the type of request/reply)
source MAC (6 octets), source IP (4 octets, all zeros if this is a
reverse-ARP), destination MAC (6 octets), destination IP (4 octets, may be
FFFFFFFF for a broadcast).
hombre's IP address appears because it's the sender address of the packets;
the name appearing in the second packet suggests it might be a NIS packet
of some sort.

Some of the HP deskjets with JetDirect cards can only be setup/accessed by

That's the address you need for /etc/ethers on a RARP server (or
/etc/bootp.conf on a BOOTP or DHCP server for clients that talk something
more sophisticated than just RARP).

LPD refers to the use of the Berkeley 'lpr' line printer protocol, commonly

Some more experimentation is needed to be sure what all the symptoms really
mean. However, obviously the printer isn't responding to an ARP request
for what should be its own IP address. Therefore either it is using some
other IP address, or it has lost it's configuration and needs to be
supplied an IP address (by RARP or otherwise), or the interface is
broken/dormant.
I expect that this printer, which is quite old, can only use RARP (which is
an old and simple protocol, but still in use), not BOOTP or DHCP, to get an
IP address. If it were actually trying to do so, you ought to see some ARP
packets emanating from the printer, with the printer's MAC address as the
source, and the Ethernet broadcast address as the destination. Since
you're not seeing that, I assume the card is either completely faulty (no
link light etc?) or is so badly misconfigured (possibly the setup has been
corrupted by age, or suffers from flat battery if there is one) that it
needs reset to factory defaults before it will operate.

Same family, same instruction set as 6502, just a different bus structure.
Some of them have reduced address busses, one or two may lack one or two

are part of the R65xx family. The original R6502 data sheets lists the

One of the next things on the agenda (after finishing the VCF Marketplace)

The VCF will eventually become an international "society" dedicated to the
preservation of old computers and computer history. The VCF events are to
be yearly gatherings that cap off activities that occur throughout the
year. My desire for the past couple years has been to sponsor local
computer collector clubs throughout the world, to create local interest
that then grows into a connected network of clubs.

Ok, likely this won't work for Calcomp, but HP stuff uses a default
IP address of 192.0.0.192 for their network interfaces. Try setting
up a separate computer and give it an address on the 192.0.0.0 network.
Then try pinging it...
If that doesn't work, this next idea will take some time and preparation.
Get a Windows 2000 or Windows XP machine. They allow you to change the
machine's network address on the fly (can Linux do this?) using the NetShell
(NETSH.EXE) facility. The syntax is:
netsh interface ip set address "Local Area Connection" static <my_ip>
<my_mask> <my def_gw>
Write a BASIC program that writes out a batch file. Have it iterate
through the possible range of network addresses, sending a broadcast
ping for each network. Have the output from ping redirected to a file
using the append mode ('>>'). Search through the file until you find
the network address to which the printer responded. Then make a small
change to the BASIC program to iterate through all the node addresses
on that network until you find the IP address of the printer. Set up
the Windows box to be on that network, TELNET to the printer, change
the IP address back to 111.1.0.1 and you should be all set.

The 74289 is also the same part/pinout save for instead of open collector
they are
tristate outputs.
The 74382 is not an ALU, it's a carry look ahead generator. The 74381 is an
ALU.

BZZZT!!! By ealy 1980 the 2901 was already passe', as were TTL cpus.
I presume by that you really meant early (very early) 1970s as the 2901
is a 1970s part.
Also the 2901 is directly traceable to 74181, 74189 like parts.

Which is really slightly naughty, as 192.0.0.0/16 is NOT in the private
address range (that would be 192.168.0.0/16). But that's not relevant to
Arno's problem :-)

MOST systems other than Windows can do this :-)
It's not a good idea if you need to go through all the networks numbers
(see end of this post for the reason, if you've not realised yet).
If you want to try the Class A addresses, it would be rather easier to do
on one of the Suns, just by writing a script that cycles through the
network numbers in a loop, issues an ifconfig for each iteration, and a
broadcast ping (with the number of packets emitted restricted to a quantity
of 1 or 2).
Assuming the devices of interest are too old to understand CIDR, there are
three ranges of network numbers to consider: class A, class B, and class C;
ie those with 8-bit network numbers and 24-bit host parts, 16/16, and 24/8.
The quick and dirty way is to run the script once for each class, so
that's networks 1..127 with subnet mask 255.0.0.0, networks 128.0 ...
191.255 with netmask 255.255.0.0, and 192.0.0 ... 223.255.255 with
255.255.255.0 (the rest are multicast or reserved addresses). Of course,
if the printer's IP address has been really scrambled, it might end up in
the reserved range, and I can't think of an easy way to get at that.
Unless the Sun has something like the range(1) command, it's probably
easiest to make a file containing each list (call the files netsA, netsB,
netsC, for example) and then do something like this in the script:
#!/bin/sh
for i in `cat netsA`
do
ifconfig le0 down
ifconfig le0 ${i}.0.0.2 broadcast ${i}.255.255.255 netmask 255.0.0.0 up
ping -c 2 ${i}.255.255.255 2>&1 >/tmp/responses
done
Check the syntax of ifconfig (and where it is, it might not be in the
normal PATH) as I've not used an old Sun for a while. Ditto for ping.
It's in /usr/etc/ping on my IRIX boxes, /sbin/ping on recent Solaris, but
I can't remember where it is in SunOS. Don't be tempted to simplify the
sript by using the "local broadcast" address of 255.255.255.255 every time,
as some things deliberately do not respond to that (my HP printers don't,
nor do my switches).
Don't forget to restore the original address with "ifconfig le0 111.0.0.1
broadcast 111.255.255.255 netmask 255.0.0.0 up" when you've finished :-)
It'll take a while to work through the class C range, because ping will
take a while to time out on each network number :-) Say two seconds per
network, thats (224-192) * 256 * 256 * 2 seconds, about 4 million seconds,
or just over 48 days. Oh, and you'll probably want to refine my shell
script to eliminate the unneccesary lines generated by ping recording
responses from the Sun itself, and the headers. You don't need 12 million
extra lines in the output :-)

I am looking for this discontinued piece of software that allows PCs to
connect to MACs via appletalk.
I need one copy of the PC software preferably two (each with unique serial
numbers).
We are doing performance analysis.
