UTC Transformer type H-89

by acme_ent＠bellsouth.net

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? Glen 0/0

OT: Determining TCP port ownership

by rcini＠optonline.net

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?

EISA - was VLB SCSI?

by mhstein＠usa.net

Since I don't have any EISA experience other than this, maybe I'm missing something really fundamental...

Am2901 bit-slice

by CLeyson＠aol.com

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 processor just for the fun of it. Any suggestions ? Best Regards Chris Leyson

Agreed. I first saw it in Practical Electronics (which I started reading in 1977/78 or so). It was often used in the parts lists. It confused me slightly the first time I read it, but it was clear what it meant. I don't know the derivation off-hand but I am surprised that anyone uses "one-of" - it's just harder to say! Antonio

AT&T 6300 Keyboard Controller

by tarsi＠binhost.com

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 210 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 -- ---------------------------------------------- Homepage: http://tarsi.binhost.com binHOST.com: http://www.binhost.com Forever Beyond: http://www.foreverbeyond.org ----------------------------------------------

Thick Ethernet/Sun networking problems

Quite ingenious. 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". -- Pete Peter Turnbull Network Manager University of York

EISA - was VLB SCSI?

by mhstein＠usa.net

Hmmm, that reminds me: I have an EISA Compaq 486sx at a client site from which I had to remove an add-on internal modem; ran the diagnostic/configuration program, it says everything's fine, but when it boots it stops waiting for F1 saying the configuration's incorrect. Press F1 to continue & everything works, just a nuisance 'cause it can't restart after a power failure without someone there to press F1. Any ideas? Can give more details off-list if anyone can help. m ----------Original Message---------- Date: 1 Nov 2001 1:11:30 +0100 From: "Iggy Drougge" <optimus(a)canit.se> Subject: Re: VLB SCSI? ...What I dislike about either system is that it's so awfully software-based.

[...] > If the IP is reset back to 0.0.0.0, then the second step is to use the > reverse-ARP procedure to set the IP address. 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). -- Pete Peter Turnbull Network Manager University of York

Thick Ethernet/Sun networking problems

OK Pete (and everybody else, of course), I admit that was a *long* break since I brought that up last time - but now I think I have collected enough information for a new chapter...So, where did we get stuck?

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 ?

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.

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)... >On most of the Ethernet-enabled printers I've come across (mostly HPs, Lexmarks, and Xeroxes) you >can do the setup from the front panel -- sometimes tedious, but usually not too hard to understand. 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. >Have you tried printing out status pages? Sometimes that will show you things like IP address, >protocols enabled, that sort of thing. Usually you can do it by holding down one of the buttons when you >turn the power on. 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: CalComp Internal Ethernet Adapter Revision 4.11, Datecode 12/20 1994 10:20 Burnin Value = 0 SRAM = 256K bytes, Novram = 128 bytes Ethernet address 00 C0 E2 00 0C 8E Ethernet options: Ignore Alignment Errors Auxilliary data port = 0 IP address: 111.1.0.1 Telnet password security: OFF Netware options: !!!

EISA - was VLB SCSI?

by mhstein＠usa.net

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. mike -----------Original Message---------- Date: Fri, 02 Nov 2001 02:45:53 -0500 From: Chad Fernandez <fernande(a)internet1.net> Subject: Re: EISA - was VLB SCSI? re-read what he said..... he isn't loosing the configuration, it justs wants attention. I have had this happen before too. I just change things until it stops :-) I think something gets crossed up when changing things around too much, and it asks for F1 to be pressed. You can start over from scratch by pulling the battery..... I have had to do that once or twice when I really screwed things up, to the point that it hung while the bios was loading :-) Chad Fernandez Michigan, USA

Haven't you ever ended up with a disk which you don't know what it might contain. For all intents and purposes, it might contain the VAX/MIPS sources. =) So what do you do? Plug it into every computer where it would fit? That could become quite tiresome. So, to get to the point, is there any software out there which might identify what OS or filesystem is on a disk? It really shouldn't be too difficult, just a matter of identifying some hundred partition tables, MBRs, RDBs or boot blocks, right? -- En ligne avec Thor 2.6a.

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. m -----------Original Message------------ >> The 74382 is not an ALU, it's a carry look ahead generator.

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. > > It'll take a while to work through the class C range > Yes, I'd say he would benefit from some filtering if he > has to check all the class C range, but I was assuming > this could take a couple of months, worst-case... 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. -- Pete Peter Turnbull Network Manager University of York

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 > 0806 (ARP), the remaining 5 were type 0800. 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. > OK, as I didn't finde snoop on the Suns (and didn't want to fiddle with > compiling programs by myself at this stage...), 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. > I set up a PC with a network > card, packet drivers and EtherLoad 2.00.

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. > 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. 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. > Is there a DOS based sniffer out there which will produce output as > understandable as snoop? There's an old version of LANdecoder that runs under DOS, I think.

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. -- Pete Peter Turnbull Network Manager University of York

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. hth, -doug quebbeman

COPSTalk, which was (I think) the descendent of TOPS, was available for public download from the URL: http://www.downloadsafari.com/Files/utilsnetmisc/C/COPSTalk.html but I didn't have any luck. PC/MacLAN, from Miramar Systems, is still commercially available. I have some licensed copies of an old version (runs on Win95 only) I'd let go for $200. Or, you could buy fully licensed new versions for about $159 each. They're at: http://miramarsys.com I've also got COPSTalk laying around somewhere... Regards, -doug q

Thick Ethernet/Sun networking problems

But that's not relevant to Arno's problem :-) > 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?) 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 :-) -- Pete Peter Turnbull Network Manager University of York

I did read what he said. Sometimes in the early Compaq 486's (and also late 486 Olivetti/NCR/AT&T) you get the error. Used to have a slew of the monsters at work we got cheap to replace dying IBM's. We replaced them with.. Wait for it.. I'll give you a hint, we were bought by AT&T.. NCR 3230's.. Ugh. At least at EOL we could re-chip them, crank the clocks and toss regulators in for employees that wanted one. Nothing like seeing the message "486DX4 running at OVER 100mhz" and chuckling.

hard-sector 5 1/4 disk

by mhstein＠usa.net

Hmmm... you don't use Windows much, do you... ------------------Original Message---------------- Date: Wed, 31 Oct 2001 15:29:50 -0700 From: "Richard Erlacher" <edick(a)idcomm.com> Subject: Re: hard-sector 5 1/4 disk The way I seem to remember it is that, back then, we were amazed when things worked, rather than being irked when they didn't. Apple's attitude was clearl, though, and that was that if your data really mattered, you'd certainly use a computer and not an Apple. The Apple wasn't designed from the ground up as a computing machine, but rather as a video toy (not in the disparaging sense) on the order of the several other video games of the time, which, coincidentally could also do some computing. Apple's approach was that if people were willing to buy an Apple and then use it for useful work, they'd try to charge as much as they possibly could, since the overall cost ostensibly would be low initially, and then they'd make their money on the disk drives, (where they had some real margin) and other add-ons that it took to convert the Apple into a computer capable of doing useful work. What makes all this crystal clear is that if I fire up an Apple today, it still does all the stupid disk-subsystem-related crap it did back then, only, by now, nobody would even think of putting up with that. Back then, it was about par for the course, but it wouldn't last a week in today's environment.

classiccmp-digest V1 #761

by ajp166＠bellatlantic.net

Those parts were never cheap! You can also use 74289s for the '189s. The '382s are an improved version of the '182. A note, if you can tolerate a slower ALU you can omit the '382s and just use ripple carry. A sub for 74189s is some of the byte wide cache rams from an old 386/486 PC as the faster ones were faster than the TTL 74189! You dont have to use the full space of the cache ram though having it would make afor an interesting register array.

Heh... depends on the mainframe. The CDC-6600, the world's first supercomputer, was for many years rated as having a mine-hour MTBF... turned out that was because a counter was oveflowing after 9 hours of ticking away, and only under one particular operating system (SCOPE). But even under the more-stable KRONOS operating system, the field engineers typically took it down for an hour each morning. Periodically, they would polish the platters on one of the disk drive units (in the early 90s, we used to kid about using Lemon Pledge to cure stiction, but they drives *really* did get polished), while smoking a cigarette.

Pictures, anyone? I don't have the manual to hand right now but my recollection is that it is roughly chest high, about as wide and deep as a UK fridge and would be a pain to load into anything other than an estate car (station wagon to you IIRC). In fact, even in an estate you may find that the box is slightly too high to fit. I picked up a BA123 in my car a few years ago and, although it did fit, lifting it in (with help) and out (without help) was harder than I thought it would be. Antonio

hard-sector 5 1/4 disk

by mhstein＠usa.net

Now that you jog the old grey cells, of course you're right; in fact, the manual states "You should make sure that you buy diskettes for SOFT SECTORED FORMAT (in caps!)... What confused my recollection was that I remembered making a few bucks selling hard-sectored diskettes to PET dealers when the FDDs first came out, but now that I think back it was probably because they were cheap & we'd discovered that they'd work, not because they were required. I did think that the high-density drives used at least one index hole, but no, just looked inside the 8050 and no sensors; wrong again (and how many times have I ranted to myself that people who don't know what they're talking about should keep their mouth shut).

CPU design at the gate level

by ajp166＠bellatlantic.net

The fake for that using discretes is one transistor per emitter used with the bases and collectors as common. The other is diodes. The real problem is level shifting and the use of excess redundant transistors.

Emulex Qbus Disk controller? (Wiring diagram for connectors?)

by CordaAJ＠nswc.navy.mil

Thanks! I believe I have a couple of ESDI drives hanging around from one of my SGI 4D/70 behemoths.... I've done another quick deja search and, while it's confirmed the ESDIness of the controller, There doesn't seem to be any info out there as far as the DIP switch, and pinouts for the connectors. (I also checked a few other sites I know of that have scanned DEC manuals, but no luck... anyone know of a site with a scanned manual for this critter?) If I remember correctly, ESDI has a MFM-like interconnect with separate control and data cables. The control cable daisy-chains across the drives, while the data cables star out from the controller to each drive. Since my controller has 3 connectors, I would guess that it probably supports 2 drives (one connector driving the control cable, and one data connector for each of two drives) What I don't know is the pinouts for the connectors on the controller (since all 3 connectors appear to be identical in size and SCSI-2 form factor) does anyone have a clue as to the connector assignments and wiring pattern? I can possibly hack a couple of SCSI2 cables to make a viable adaptor... -thanks- -al- -acorda(a)1bigred.com > -----Original Message----- > From: Chuck McManis [mailto:cmcmanis@mcmanis.com] > Sent: Wednesday, October 31, 2001 4:00 PM > To: classiccmp(a)classiccmp.org > Subject: Re: Emulex Qbus Disk controller?

VAX 6400's futile attempts to booting Ultrix 4.1, still some progress ...

by gunther＠aurora.regenstrief.org

Hi, O.K. the good news is that I managed to boot VMS, read all 40 files from the Ultrix 4.1 boot tape without error (and with the right block size :-) and write those files back to a TK70 tape without major problems. I know that the tape is good and the drive is good. (At least good enough.) And still we won't boot. But that means that something is wrong with that Ultrix version 4.1. It doesn't work on the VAX 6400. Fortunately I am in the position of access to sources that would allow me to build an Ultrix 4.2 based loader. However, I'm even convinced that it isn't the loader's fault. The 4.2 sources of the loader show that it always prints an error before halting. And I never see an error. In fact the only way for the loader to exit without a message appears to be its non-returning call to the vmb.exe gizmo. And -- oh bummer -- I don't seem to have source code for that one. The interesting light pattern at the TBK70 board and the console fault light seems not to indicate a read error >from tape, but more likely a futile attempt of some boot stage of getting to talk to the TBK70 and carrying on the next boot stage. Too bad I can't find out when and where this happens. Anyway, quite likely its in the vmb.exe gizmo which is a black box. So, I might need some boot tape of a newer version (one that properly supports the VAX 6400 series) or I have to find an alternative booting strategy. I guess the MOP booting of ultrix might becoming a more feasible option. So, here is a call upon all of you who know something about MOP booting Ultrix. Please give me any info you might have. I have mopd and am on FreeBSD as the boot host. ... ... ... Another alternative is to set up an "InfoServer" VAX station with a CD ROM and an Ultrix CD of a post 4.1 version. Is this something someone has available? May be in the area or something one could set up accessible through the Internet (a 36 kbps modem line, ahem...) Once I have Ultrix up on one machine I can help others to do the same. If not by writing a boot tape by ... ... here is another option how a good soul could help me get going: If you have an Ultrix 4.2 or higher running on an RA disk, I would appreciate a disk image. That I should be able to raw write to another RA90 (or RA82) using VMS and then boot from that disk. Just make sure there is a GENERIC kernel on the disk image. I still don't have a KFMSA, so RF disk images would not help me. Except, perhaps, if someone has Ultrix 4.2 or higher running and some spare disks to tinker with, I might be able to fiddle a generic disk image that could be installed on any disk. BTW: after having fixed my TU81 unit number problem, I still can't boot from TU81. Seems like the VAX 6400 with my EEPROM revision doesn't know how to boot from TU81. If someone (Geoff?) knows he can boot that way, may be I could use an EEPROM update. Would appreciate your EEPROM dump then.

Emulex Qbus Disk controller? (Need help identifying this one)

by cmcmanis＠mcmanis.com

Search on Emulex QD24 and you'll be rewarded with the information that it is an Emulex MSCP ESDI disk controller. Which can be just as useful as a SCSI card since finding a couple of 300MB ESDI drives shouldn't be too hard. I think I've got a 170MB one laying about somewhere. Kirk Davis (kdb(a)ndx.net) mentioned he had some SCSI controllers he was thinking about trading for PDP-11 gear. Also I just missed a lot that had about 10 Dilog SCSI controllers on it at a local scrap/bid place (had I known I would have bid more than the $75 it went for :-() my interest was in the more mundane things like a couple of DSSI ID plugs and an external DSSI disk expansion box. --Chuck At 11:32 AM 10/31/01, you wrote: >I'm trying to bring up NetBSD on a Vax 4000/300, and so I'm >looking for a MSCP SCSI disk controller.

Emulex Qbus Disk controller? (Need help identifying this one)

by CordaAJ＠nswc.navy.mil

I'm trying to bring up NetBSD on a Vax 4000/300, and so I'm looking for a MSCP SCSI disk controller. After going through my stack of Qbus boards (collected from hamfests, etc.) I came across one that looks like it might be a SCSI controller... unfortunately, I haven't been able to confirm it, since a google search turns up very little on it (a bad sign...sigh) The board is labeled: "Emulex Corp QD2410401-02 rev F" It has 3 connectors and a DIP switch on the front plate. The connectors appear to be of the SCSI-2 form factor. Has anyone run across this critter before, or tried it with NetBSD? Come to think of it, Is this even SCSI, or something else entirely? Also, does anyone know where their might be some on-line docs for it, or at least a description of the DIP switch settings... -thanks- -al- -acorda(a)1bigred.com

HP 2000 notes

by sieler＠allegro.com

Hi, Seen on another newsgroup, I thought this might be of interest to HP 2000 collectors ... particularly the note about "dozens of paper tapes" :) ------- Forwarded message follows ------- Date sent: Wed, 31 Oct 2001 11:11:28 -0500 Subject: Re: [HP3000-L] OT: HP2000? From: John Korb <johnkorb(a)LASER.NET> To: HP3000-L(a)RAVEN.UTC.EDU Send reply to: John Korb <johnkorb(a)LASER.NET> The HP 2000 is a very old machine, the last of which rolled off the assembly line in 1978. George Mason University (the State University in Northern Virginia) had (it is long gone) the next-to-last HP 2000 produced. It ran a version of the operating system with date code 1812. The operating system on this system was "HP 2000 ACCESS BASIC". The system GMU had (which was fairly typical of the HP 2000's of the day) consisted of the following hardware: -- one 21MX-E processor with 64K bytes RAM, used as the "System Processor" -- one 21MX-E processor with 64K bytes RAM, used as the "I/O Processor" -- one 7970E nine track 1600 CPI tape drive -- one 7920 disc drive with 50 MB capacity, of which the Access operating system could only address the first approximately 33 MB -- one 2617 line printer -- one 2392A card reader -- one 2640b terminal as the system console The operating system supported 32 users. As the "HP 2000 ACCESS BASIC" name implies, the system supported a single language, BASIC, but it was a good one, and the old BASIC/V on the HP 3000 appears to be an expansion of the HP 2000 ACCESS BASIC. There were interfaces RJE, and many HP 2000's supported users who created/edited batch jobs on the HP 2000 which were then submitted through the RJE interface to an IBM, CDC, Univac, or other mainframe (as GMU did). There was no print spooler or spooler for the card reader, so people wrote their own, in BASIC, some supporting GE Terminets or DECwriters as remote spooled printers. The accounting structure was based upon account names consisting of four characters - a letter followed by a three digit number. The "A000" account was the equivalent of the HP 3000's "PUB.SYS". It was the system library account, and had special privileges. It was here that you placed the "HELLO" program that every user ran when they logged in, whether they knew it or not. Group library accounts on the HP 2000 were those accounts where the three digits in the account name were "000". For example, all users in the accounts D301 through D399 would be allowed special access to programs/files in the D300 account. The Z999 account was used by HP for special purposes. It has been so long now that I don't remember what the unique capabilities of Z999 were. The HP 2000 also had the capability of running other operating systems in stand-alone, single-user mode. One of these was Fortran, but I never used it so I can't comment on it. In my basement I still have dozens of paper tapes of HP 2000 BASIC programs. In 1999 and 2000 I converted some of those to run on the Classic (16 bit) HP 3000 in BASIC/V. The most difficult part of converting HP 2000 BASIC programs to run on the HP 3000 is that the disc files on the HP 2000 were based on 512 byte "blocks", which means that any HP 2000 application "smart" enough to know the algorithm used to calculate how many free bytes there are remaining in a block (there are overhead bytes for each string, etc.) has to be painfully rewritten to run on the HP 3000. That's about all I have time for. I hope that gives you some feel for the HP 2000. There were many of us who loved that little system. As to whether there are any still running, I don't know, but I doubt it. John At 2001-10-31 10:21, David T Darnell wrote: >Dear List, > >I've seen references to the HP2000 a few times on this list.

Apple II accelerator and Micromodem II questions

by dlw＠trailingedge.com

I have what looks like an accelerator board for an Apple II. Looks like a Saturn Systems Inc. Accelerator II. Has a 65c02c and 64 K of ram on board. Anyone have any info on this? Doc? What the jumper settings are (there is an 8 switch jumper block on it) or any software needed to use it? This system also has a Micromodem II in it but no doc or the interface from the board to the phone plug. Anyone have a spare plug or the pin outs to make one? Thanks. ----- "What is, is what?"

Unless that was a remark about a certain state, in which case I'd say, "Hey watch it! This is a family list..." ;-)

[Fwd: value of scrap]

That might not happen with circuit boards though. What's being recovered is Gold, Palladium, Tantalum, maybe some silver, among other materials. And the competition amongst recyclers to be the one to be able to service this ought to keep them willing to pay for the raw materials. But break your equipment down, so you're just turning in the circuit boards. And if you separate the low yield PC grade ones from the high yield commercial grade ones, you still might do all right with them. > > Here in the UK that might change soon.

A twist on blinkenlights

by dpeschel＠eskimo.com

While visiting the San Francisco area for the Computer Museum History Center's awards dinner, I swung by Stanford to see their exhibit of old (largely Stanford custom) computer hardware. Various groups at Stanford had computer systems (mostly PDP-6 and -10 I believe), but the exhibit highlights the Stanford Artificial Intelligence Lab, a.k.a. SAIL. SAIL had a multiprocessor system containing a KA10, a KL10, and a PDP-6, as well as two smaller computers dedicated to video control, two megawords of memory (eight times the address space of the -10), and disk storage, so they obviously had enough blinkenlights for anyone. But one of the programmers added a box (looking more or less like a tiny traffic light) to his office. Green meant "normal operation". Yellow meant "parity error". (Failures tended to happen in clumps, so after finding one error, the software would kill the affected job and then search for all other errors and kill all other affected jobs.) Red meant "The OS has halted an Exec-mode DDT is running". (Think "kernel debugger".) No lights meant "Things are really messed up". Not exactly high bandwidth, but still an elegant metaphor! -- Derek

MIPS/VMS

by vance＠ikickass.org

I was told at one time that work had begun on MIPS/VMS just before DEC's abandonment of the DECstation line in favor of Alpha. Does anyone (maybe a current Compaq employee) know where in some dark corner the sources might be found? Peace... Sridhar
