CI networking, need some help debugging ...

by gunther＠aurora.regenstrief.org

Hi, I have now the two VAX6450s with CIBCA and connected through the star coupler. I was eager to see them talk IP through the CI but unfortunately it doesn't work. I'm under Ultrix 4.5 and I use ifconfig scs0 inet 192.168.17.1 netmask 255.255.255.0 on the one machine and ifconfig scs0 inet 192.168.17.2 netmask 255.255.255.0 on the other machine. If I check the status with just ifconfig scs0 It says it's up and fine. But ping self doesn't work and ping each other doesn't work either. From reading the scs man page, it mumbles something about host numbers having to be between 1 and 15. But I have no clue what they mean. I don't know my CI node numbers either. I'm wondering if I should know those and configure them somehow. I also wonder if this SCS IP has some arp? Would be really cool to have tcpdump for Ultrix. What's the best way to step by step get a CI system debugged? thanks, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

Anyone have a data sheet on the MC3242?

by erd_6502＠yahoo.com

I'm stripping interesting parts off of these stat mux boards that I recently got around the corner - lots of socketed 6502s and 65c02s, 2532s and the like. Many of the boards have a 24-pin DIP MC3242 which I can find little about - Google only gives me one meaningful hit that it's a "Motorola Mux and Refresh". I'm trying to determine if it's worth desoldering any. I'm currently using a hot-air desolderer, so it's not a _lot_ of effort, but, for example, I'm not bothering to pull the popcorn TTL parts, just memory and "interesting" parts. So... anyone have any information on the MC3242 and why I might want to save a couple dozen of them? -ethan __________________________________________________ Do You Yahoo!?

Test results of SCSI devices on MicroVAX 3100

by bob_lafleur＠technologist.com

I've accumulated a stack of external SCSI-2 devices that I thought I'd try out on my MicroVAX 3100. All devices show during a SCSI bus scan >from the console prompt, and as devices when VMS 7.3 was booted from the internal hard drive. But they worked with varrying degress of success. Here are the results: "GENERIC CD-R CRD-800S" - This is an 8x CD-R (not CD-RW) drive; it reports as "GENERIC" but it really is a Sanyo CD-R CRD-800S. I've even updated it with the Sanyo firmware and it still reports as "GENERIC". I tried to boot the mini-VMS in SYS1 of my VMS 7.3 CD-ROM. Boot failre right away. Booted VMS from the hard drive, and tried to mount a CD-ROM, and I got invalid media format. "Yamaha CD-R 400c" - This is a 4x CD-R drive. I tried to boot the mini-VMS and it started to boot, until after it asked for the date & time, then it went into mount-verificiation mode, and just hung. I booted VMS from the hard drive, and tried to mount a CD-ROM disc and got the same message as with the CRD-800S - invalid media format. "Toshiba XM-3401TA" - Just a plain old CD-ROM drive, I think it's a 2x. I could boot the mini-VMS in SYS1 from it, and when I booted VMS from my hard drive, I could mount CD-ROM discs fine. No problems with operation at all. "MATSHITA LF-3000" - This is a 128MB MO (magneto-optical) drive, it's in a box badged "Optical Access International" and I originally purchased it for my Mac - it has always worked fine on the Mac. From the console prompt, a TEST F1 (SCSI OPTION Utilities) device scan showed it with a device name of JK (JKB400 in my specific situation) and the device type shows as "OPTDISK" but when I booted VMS from the hard drive it showed as a DKB400 device. I tried it INIT a disk, and got a "media is offline" error. I've had similar results trying to make this drive work on the PC - it is recognized fine, but when I try to use it, it seems to go away. Maybe there is newer firmware for it that corrects the problem, but it isn't a major issue at this point. I do find it strange that the console shows it as a JK device, but VMS shows it as a DK device. "TK50Z-GA" - Of course, it worked without a problem. Has anyone tried a Travan 4 SCSI tape drive? Specifically, the HP SureStore T4? - Bob

Mounting CD/tape devices inside MicroVAX 3100-90

by bob_lafleur＠technologist.com

I'm not really sure how the RRD43 that's in my MicroVAX 3100 is attached... There appears to be a metal bracket that's part of the system, with screws going into the sides of the RRD43... Or is that an integral part of the RRD43? I have space to mount a second drive, and I might like to put a tape drive in. But I don't see where I would screw it in... Do I need some sort of mounting bracket? If so, does anyone have any spares?? Thanks for any tips. - Bob

RA82 belt tension adjustment, how?

by gunther＠aurora.regenstrief.org

Hi, I just tried to spin up my RA82. Problem is the motor starts for a moment and then stops. Fault light comes on. Pressing the fault button and "B" flashes. I assume that my RUN button light is not working, so then the indicator pattern indicates a spin error. How can I fix that? I suppose it is the belt tension. I only have the RA81 maintenance manual, and although they are pretty similar, the belt tension stuff in the RA82 is not at all like what is described in the RA81 maintenance manual. Someone here knows how that is done? Or what else could be causing this spin fault? (I see that the motor starts but it is stopped within a second after it started.) thanks, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

can you check the behavior of your KDB50 during booting?

by gunther＠aurora.regenstrief.org

Hi, I am having a problem around the KDB50 of one of my VAX6k's and need your help. If you boot from a KDB50, could you check if the yellow indicator LEDs turn OFF for the moment that the drive is first accessed? I am getting the error, device not accessible. I could boot from that same path before until the moment that I connected another RA92 and an RA81 and I switched the drive unit numbers of two of my RA90s around. After I swapped those unit numbers I can't get any of the drives to boot any more. My fear is that somehow the KDB50 is dead. So, next time you bood your VAX through a KDB50, plese watch the yellow indicator LEDs closely. Mine go on in the early initialization process and stay on throughout the self test. Then when the boot sequence is entered those lights go off for a few seconds, the red FAULT light goes on at the console. After one or two seconds the yellow indicator LEDs go back on and FAULT light clears. Then the typical blink pattern of the little red LED is engaged, but at that time the VAX is already halted with that I/O error. thanks, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

by mythtech＠mac.com

>It does sound a _little_ high, but it might be OK. Try loading it (A 100 >Ohm wirewound resistor would do, for example). See if that brings the >voltage down to nearer 9V. I tried a 100k Ohm since I didn't have a 100 Ohm, no effect. I don't have a bulb or anything handy to try with that. I think I am going to dig out the modem it goes to, and test the voltage with it hooked to that. That will at least give it real use load (the modem powers up just fine, it just fails to respond to all AT commands except for getting the firmware, and it won't attempt to go off hook or dial... I'm not 100% convinced the modem is really "dead" so much as it just doesn't want to co-operate). Thanks to all those that responded...

new finds :-)

by rigdonj＠cfl.rr.com

Went to a small local hamfest this morning and came home with a Z-80 trainer made by E&L Instruments (remember the Bugbooks?), a Gunnplexer cookbook, a HP-15C with manual, HP-18C with manual and four HP Solutions books, and a HeathKit Most Accurate Clock II with manuals (receives time code from WWV and sets itself automaticly. Has LED display and serial link to connect to a computer). Passed up a TRUCK LOAD of Amigas and other Commodore stuff for $10. Not bad for an hour of looking :-) Does anyone have the manual for the E&L Z-80 trainer? It's mounted in a black plasic case and is marked "The Fox" and also model MT-80Z. It has two circuit boards, a bread boarding area, a Std Bus expansion connector, a keypad and six digit LED display. Joe

I hate Radio Shack

by mythtech＠mac.com

>Those kids get paid minimum wage and >know minimum when it comes to anything other than cell phones and >stereos. Last I knew around here... they get paid on commision with the Manager being the only one with an hourly pay. And that goes a LONG ways to explain why they don't *want* to care about the little $1 and $2 components, but would rather sign you to a DirecTV or Cell Phone, or MSN service. It is the only way for them to make any real money out of the place. At least the local Rat Shack that I go to isn't too bad to deal with service wise. The reason being is these guys like I said above, don't care about the little parts, and really don't want to waste time helping someone with them. That is time wasted that they could be trying to convince someone to buy a high priced item or service or anything that might make their weekly pay check come close to that of a McD's burger flipper. That works out in my favor. I can walk in to the store, head right to the misc parts section, and watch every sales goon turn around and walk away >from me. From them, NO help is GOOD help. -chris <http://www.mythtech.net>

Corvus Omninet... TRS-80?

by florit＠unixville.com

I have a TRS-80 I got from Weird Stuffwhile I was living in Silicon Valley. It was the last few left from what aparently was a school 'Please take these dinos away' disposal. Its a model IV, but has no drives. I was tempted to gut the case, create some sort of adapter for the keyboard to connect it to an internal PC mobo and replace the monitor as well. Needless to say I never got around to it. Its in working condition, (turns on, goes into basic, keyboard works) but the case is showing its age and exposure to the elements. While I was in the process of taking it apart to clean it up, I saw two butterfly nuts with a piece of what seemed a cut off telephone cable, 2 leads. I asked on the trs80 newgroup and they mentioned that it could be a now little known networking card for a system, Corvus Omninet. This would explain the diskless condition of the TRS-80, as it would load up its files over the network to do anything interesting besides load up the basic rom. Since I didn't hack the TRS80 into the abomination I was thinking of, I would like to sell it (cheap! take it off my hands! I've too many computers) to someone more interested in it; mail me offlist: florit @t unixville.com Anyone have a server for this setup? Definitely cool on the unknown factor.

That should make Hi This does require that you have full control of the bus. I have used the 00H as well as the 0FFH. When you have a partially working bus, running code is prefered because simply pulling the ROM may not always work Some broken device may inject and instruction and break the loop. It is good to have all three methods of running addresses in your tool box. It is too bad that the simple 00 and 0FFH codes don't work for all processors, like the 8080's.

[OT] measuring DC wall wart

by mythtech＠mac.com

>Hey, you know what? I missed the beginning of this thread, but this is >exactly the sort of behavior you get from a modem which requires a 9V AC >power supply, when you run it with a 9V _DC_ supply. Interesting. The wall wart I used with the modem is the one that was in the box along with all the other assorted parts. The wart has a label marking it as the same manufacturer as the modem, so I didn't even think about the fact that it might not be the RIGHT wart. Maybe it is really >from a different model modem. I didn't persue the issue much since the modem is a Global Village for a Mac. They are great modems... IF you have the right software. Without it, they tend to be a pain in the ass. Since I don't have the exact software that shipped with this model, and since the firmware claims it is a French-Canadian modem, and I only have US-English software... I didn't waste much time working on it. But maybe I will do a little more research and see if it really should have an AC adaptor, not a DC one. Thanks -chris <http://www.mythtech.net>

VMS doesn't recognize all physical memory?

by carlos_murillo＠epm.net.co

Hello everyone; I have noticed that OpenVMS 7.2 doesn't seem to recognize all of the physical memory in my vaxstation 4000/60; I am sure that I have 32 MB (8MB mainboard + 6 x 4MB modules) and in fact it is recognized by the prom: KR46-A V1.1-31E-V4.0 08-00-2B-2A-F8-AB 32MB ||||||||||||||||||||||||||||||||||||||| OK 85 RESTART SYS >>> >>> show config KR46-A V1.1-31E-V4.0 08-00-2B-2A-F8-AB 32MB DEVNBR DEVNAM INFO ------ -------- ------------------------------- 1 NVR OK 2 LCG OK HR - 8PLN FB - V1.1 3 DZ OK 4 CACHE OK 5 MEM OK 32MB = SY=8MB, S0/1=8MB, S2/3=8MB, S4/5=8MB 6 FPU OK 7 IT OK 8 SYS OK 9 NI OK 10 SCSI OK 0-ST31200 5-TZ30 6-INITR 7-CD-ROM 11 AUD OK >>> Similarly, the TEST 100 command tests all of the hardware and there aren't any errors. So, as far as the diagnostics in the Prom are concerned, the system has 32MB of memory and it tests OK.

[OT] measuring DC wall wart

by mythtech＠mac.com

This is off topic, since the wall wart is only a few years old, but there are some great electrical people here, so I am asking because I know someone will know the answer. I have a wall wart to a modem. I got the modem and wart in a box of used stuff (ooh, some of which was more than 10 years old, so at least there is a reference to on-topicness). The modem failed to work from the day I got it. Today, someone that has the same modem asked if I had a power supply they could have. I planned to give them mine, since I have no real use for it. But before I mailed it to them, a voice went off in my head telling me to stick it on a meter first. It's label says it is a 9vDC, 400mA Pos-tip wart. But when I hook it up to a meter, I get 15v DC off it. That seems a little high, even for something under no load. Should I safely assume the wart is no good, and point the person elsewhere (Rat Shack sells a usuable unit for only about $14, so it isn't like the person has no other choice). Or is it normal for a 9v supply to put out 15 volts? Any that I have measured in the past have not been THAT far off (I was expecting to maybe get 10 or 12 volts, but not 15). If this thing has been pumping too much voltage, that might explain the dead modem I have (or the modem could have been used as a soccer ball, who knows, it was dead when I got it). I just don't want to send the person a bad supply, and have them fry their modem when they try to use it. -chris <http://www.mythtech.net>

I hate Radio Shack

by CordaAJ＠NSWC.NAVY.MIL

What annoys me is when they give horribly incorrect advice. I stopped by a local radio shack earlier this week to price out some RG6/U for a new DirecTV dish that I was cobbling together. I needed about ~350 feet of cable. The sales droid insisted that I'd needed to buy three in-line amps, and install them all at the dish ... (I guess he knew enough rudimentary english to read the amp packaging, and extrapolate) What bothered me the most, though, was the authoritative manner in which he described what I had to do. It took quite an effort to keep from laughing in his face... BTW, I bought the coax somewhere else, just on principles... -al- -acorda(a)1bigred.com > -----Original Message----- > From: Gene Buckle [mailto:geneb@deltasoft.com] > Sent: Friday, June 07, 2002 4:12 PM > To: cctalk(a)classiccmp.org > Subject: RE: I hate Radio Shack > > > Damnit John, you beat me to it. :) > > g. > > > On Fri, 7 Jun 2002, J.C.

[OT] measuring DC wall wart

by mythtech＠mac.com

Therefore IMHO the PSU has to be safe under >short-circuit conditions. They are not. > >And the plastic cases are very brittle and canf break, exposing live >parts. Unplugging one that's been accidentally kicked, for example, is >not easy. Not saying the ones in the US are safe or good, but they are not like the one you describe. They are a white plastic, rather "soft and durable" material. You can smack then and kick them and step on them, and they stay in one peice. Also, they don't sell that cross tipped one like you describe any more (at least I haven't seen one in a long long time). Rather, all of them end in a jack, and they include one tip of your choice (for most, some include multiple tips). So you pick the connector style you need, and then that plugs into the jack on the cord. It is marked on the cord with "TIP" and the connector has a "+" on it, so you can align it for either positive or negative tip. Fairly decent setup, and so far, all their newer style white ones (they have been selling them for a few years now), have held up well, at least for me. As to short circuits and how safe they are... I can't really say. I've never opened one, and I can't think of a time that I have done anything other than accidentally set a multi-voltage one to the wrong voltage and watched my device get toasted (leaving the power wart just fine of course). -chris <http://www.mythtech.net>

TS-816 setup

by pat＠purdueriots.com

I'm having a bit of trouble geting my new 'shiny' Televideo TS-816 up and running. It hangs trying to IPL from the hard drive, and I can boot off a tape, which gets me diagnostics. The diagnostics look like this: ----------------------------------------------------------------- Self-testing in process. (TS-816/40 PROM V1.1) Hit "ESCAPE" Key to boot from Tape ? System IPL from Tape Drive in progress * TeleVideo Systems TS-816/40 Restore disk image from tape, V1.3 14 Megabyte on 1/4" tape cartridge Do you want to run disk diagnostic? ("Return" if NO, "Y" if YES) Y ** SELECT DIAGNOSTIC WINCHESTER HARD DISK ?? ** ----------------------------------------------- Type "I" to select Internal winchester hard disk Type "E" to select External winchester hard disk Type "A" to Abort the diagnostic mode I <--- Select the function above ** DIAGNOSTIC FUNCTIONS ** -------------------------- Type "R" to select Read-test Type "W" to select Write-test Type "F" to select Format disk Type "A" to reselect winchester hard disk <--- Select the function above ----------------------------------------------------------------- It would appear that it's having a problem using the internal hard drive. I don't have a spare sitting around to replace it with, and the cables look all securely fastened. Also, the drive seems to be spinning just fine, and I've cleared the two 'locks' on the bottom for it before trying to use it. Does anyone have suggestions for troubleshooing this problem? I'm knowledgable in electronics and can drag out my o'scope if I need to. Also, can I hook up a 5-1/4" MFM or RLL hard drive up to this thing? It's a TS-816/40 (I'm guessing 40MB drive), what should I look for (C/H/S) in a replacement drive? -- Pat

OpenVMS license expiration date

by rdd＠rddavis.org

Greetings, This afternoon I registered my DECUS^H^H^H^H^HEncompass membership number with Montagar software for OpenVMS. By the way, not knowing the CPU ID of my VAX, I entered a '?', and that satisfied their registration script. The last time that I attempted to register with Montagar, my Encompas membership ID number was rejected, so I didn't get a CD-ROM back then. A short while ago, an e-mail arrived with the license to use OpenVMS; alas, the license expires in one year. Will this expiration date have any effect on the useability of the software after the expiration date? -- Copyright (C) 2001 R. D.

Monitors for Vaxstation

by bob_lafleur＠technologist.com

What kind of monitors can be used with the Vaxstation models (2000, 3100, etc)? I know there are different flavors of Vaxstation graphics - monochrome, "GPX", etc. Which is the easiest to deal with monitor-wise? Can an adapter be built to use a standard multi-syncable VGA monitor? Thanks for any info. - Bob

Source for Jiffydos for Commodore 64-SX?

by florit＠unixville.com

I've a Commodore 64-SX (the portable) and I was toying with the idea of updating its kernel/bios/rom/whateveritscalledonthere so that it could stretch out the life of its floppy drive. There was a company called CMD that produced a replacement called JiffyDOS that worked around lots of the slow repetitive speed transfer problems >from the disk drives. It doesn't seem like they're selling the chips anymore. Anyone have a source for these, or failing that, someone have a recipe for doing this sort of thing? L

Commodore floppy drives; faster than you can type

by sieler＠allegro.com

Hi, I recall reading a line on/near/inside a Commodore 64 SX box advertising that their floppy disk drive: "Reads data faster than you can type". Is my memory playing tricks on me, or did Commodore really use such a line (or something quite similar)? Any pointers would be appreciated. BTW, I wasn't convinced that it *could* read data faster than I could type :) thanks, StanStan Sieler sieler(a)allegro.com www.allegro.com/sieler/wanted/index.html www.allegro.com/sieler

Wanted: Kaypro 2'84/2x

That's a shame! A couple of years back I asked the classiccmp list what was the "best" CP/M machine, and the overwhelming answer was "Kaypro." I like mine. It's rock-solid, and applications, compilers, etc. are easy to find. The disk i/o is slow, though. > From what I've heard, though, Kaypros are pretty > standard circuitry and shouldn't be hard to repair. Yes. I have the 84/2X schematics and I'll be happy to scan and email them to the OP if he/she will contact me offlist. Glen 0/0

Motorola S-record converter source for new project

I was turned onto this thing by someone who likes to run a recent release from Red Hat, and look what it got me: a reason to do that OS upgrade I'd been putting off. Once I did that, getting SRecord to compile was as easy as I'd been expecting, and it even worked and did what I wanted done. I expect that most folks running Linux/*BSD have installed or upgraded within the last two years and so have a sufficiently new version of gcc at this point, but I also expect that you (and other folks on this list) might not. -Frank McConnell

Around 1981 Novell came to the market with their first networking product, called S-net. It was a star based network around a specialized server machine with a 68000 processor and a proprietary NOS. It is this machine we are talking about now. You could connect CP/M machines and PCs to it. Around 1983 the first version of Netware appeared, called Netware-86. This was a multitasking file-, print and application server software package that ran on the PC XT. I do not know what the exact functionality of S-net was, but I believe it was multi-user file sharing only.
