Kennedy 9832 tape drive ( eBay 302562153660)

by cclist＠sydex.com

This one has me scratching my head. eBay Item 302562153660 Sure, it's a Kennedy 9832 drive mounted in some sort of giant hard case. Anyone know if this was a modified drive? What on earth would it be used for? --Chuck

> From: John Welch > Anyway, 'a' comes over as 000141 and 'A' comes over as 000101. Good, the console is working. > CLR > LAD > DEP OK, that loads a '0' (halt) in 0. > CNTRL+INIT > CNTRL+START -> reads 000002 OK, so it reads the HALT at 0 and stops. > CNTRL+BOOT -> Run light is on, SR Disp light is on > CNTRL+HLT reads 173150 Sounds like it may be looping in the high bank of ROM? That's not necessarily wrong. I finally figured out what the ROMs in the M9312 do; the ROMs at 765000 are the first-level diagnostic, and the console.

That makes sense; you can't write to the ROM. > Any suggestions? i) Check the ROM contents; there are two kinds of M9312 console ROMs, one for most CPUs, and one for the 11/60 and 11/70, see the tech manual for the M9312. So read out the first couple of words: CLR 765000 LAD EXAM EXAM etc and let's see what they read. ii) Try starting the console code directly: CLR 765020 LAD CNTRL+START > I have other M9312s I could try.

APE emulator

by rich.cini＠verizon.net

All ? ??????????????? I can?t remember who contacted me originally about potential enhancements to the APE (Altair Peripheral Emulator) that I have mirrored at ape.classiccmp.net. I heard from Frank Barberis and he mentioned that he?d be willing to make enhancements to the software if there was sufficient interest. ??????????????? So, if we can put together a list of desire enhancement/features I can try to get the ball rolling. Feel free to contact me off-list with ideas. Thanks!

Looking for AMP / TE coaxial connectors - Memorex 651 drive

by mattislind＠gmail.com

Hello! I am about to start with the project to archive disks from the Incoterm system. This system makes use of the Memorex 651 drive which is somewhat odd. It has 64 tracks,is hard sectored with 32 sectors and spins at 375 rpm. But I do have the drive which hopefully still is working. However the interface connector is nothing like I seen on a floppy drive before. https://i.imgur.com/TklddLP.jpg It is a AMP 202515-1 housing. The mating 202516-1 which I need is still in production and available for purchase from Mouser. The small coaxial connectors on the other hand has a minimum order of 1000 units and costs 10 euros each... https://www.mouser.se/ProductDetail/TE-Connectivity/201146-2/?qs=DuOyNqEZh0… Does anyone know of a source selling something like three coaxial connectors like this at decent price? Or maybe a suggestion for another connector that could be modified into fit somehow? Potentially using glue to fixate it. Of course the last resort is to just solder some wires directly onto the drive PCB, but if there is a nice solution I try that first.

Looking for a book on LAN Manager

by cctalk＠ibm51xx.net

Hello All, I am looking for a copy of: Troubleshooting LAN Manager 2 PDF by Michael Publication date: 10/01/1993 ISBN:155851161X ISBN13: 9781558511613 I've looked the usual areas and can't find a reasonably priced copy. There was one on epay for $10 but the day I marked it to watch suddenly it was no longer available. Interestingly enough the seller has an exact copy w/ the same description/condition relisted for $67 now... Alternatively if anyone has a copy of LAN Manager 2 OS (not just the workstation 3 disk set) w/ manuals that they no longer want I would be happy to take it off of your hands. Thanks Thanks in advance -Ali

Picked up beige Mac G3

by lyokoboy0＠gmail.com

Someone just dropped off a mac g3 at the scrapyard I work at and I picked it up. It has a failing hard drive. Replaced the drive, downloaded and burned a disk with mac os 8 on it, but it refuses to boot to it. How do I go about installing the software on this machine? Not sure if this is the place to ask, but figured it would be worth a shot. Thanks.

DR-DOS

by lproven＠gmail.com

I hope this is vintage enough. I've been playing around some more with my projects to create VMs / bootable USB keys with PC DOS 7.1 and DR-DOS. Right now I'm focusing on DR-DOS 7.1 and the DR OpenDOS Enhancement Project, because that's FOSS and AFAICS it can be redistributed, which I can't with DR-DOS 7.02/7.03/7.04/7.05 or DR-DOS 8/8.1, which were commercially licensed. I found a download of the last build released: https://archiveos.org/drdos/ First, it's the wrong size. VirtualBox can't mount it. VMware can. I truncated it to exactly 2880 sectors using the advice from ``jleg094'' here: https://forums.virtualbox.org/viewtopic.php?f=4&t=39141 VBox mounts that. But it won't boot, nor in VMware -- it just displays 2 dots and freezes. Embarrassingly late in the troubleshooting process, I've found why. I didn't think to check what was on the image! Foolish of me. I mounted it on a pre-booted VM and looked, and it's blank! There's nothing in the image at all. So, I mounted the empty image file as a loop device, copied the boot files in there and then the rest of the files in the distro archive. And lo, it works! It boots my VM just fine, and it's now running 7.01-08. All I need to do now is work out how to make the hard disk bootable, and I'm in business. The DR-DOS 7 SYS command won't do it, as the files aren't named IBMBIOS.COM and IBMSYS.COM -- they're DRBIO.SYS and DRSYS.SYS. I copied them to the expected names. SYS completes but the disk won't boot. Next step will be to try with Norton Disk Doctor. Anyway, if anyone wants a bootable diskette image with DR-DOS 7.01-08, complete with FAT32 support -- apparently it can even boot from it -- let me know. -- Liam Proven ?

All I want for Christmas is an RK8E

by chd＠chdickman.com

About 15 years ago I told my girlfriend I wanted an RX8E controller board for Christmas. I was curious how far she might go to get it for me. I ended up with two packages: one from her 8 year old daughter with a bit of 1x8 pine plank (If he wants a board, I'll get him a board!), the other package was an M8357 that she probably paid way to much for... Now the girlfriend is my wife and the daughter is getting married. This Christmas I am asking for an RK8E. I doubt it can be found at a reseller. So does anyone have or know of an OMNIBUS RK8E boardset they are willing to part with? This is an M7104, M7105, and M7106 along with 4 over-the-top edge connector blocks. I have two RK05 drives for a PDP-11, but my goal is to build an RK05 emulator based on Dave Gesswein's ST506 disk emulator. Merry Christmas, -chuck

TI 99/4a It Lives! but extended basic? acts bizarre... Great got the video cable 5 bucks from the UK - -SOLVED! Works and fires up with out the extended basic plugged in but when I pluged it in and selected the option for extended basic at book up just hangs no prompt on screen etc. I have the screed that TI had that was more of an industrial display rather than the screen that was converted TV that may have been earlier.. Heavy little monitor! It has a strong mesh looking internal mask on the screen compared to modern color CRTS/ We also have a Epson looking printer with TI logo to pair up The goal of course is to set up as a display at SMECC Museum with some of the other micros where it can be demo'ed I have the speech module too but have no idea what to do with that. Have a disc with cable but need some sort of an expansion to plug it in. The adventure continues... as always drop any ideas hits etc to us/// Learning as we go As I never used or sold any of these when in the biz back then!

Dec-10 Day announcement from Living Computers: Museum + Labs

> From: Ethan Dicks > I look forward to taking a stab at this. I suspect there are a number of people who'd be interested in MASSBUS storage devices (e.g. me - suddenly all those RH11's I've got are no longer boat- anchors :-). We should try and organize an group build, to share the load. Anyone else interested? Oh, one detail I didn't look at: what's the physical interface this uses? Hopefully three of the Berg/DuPont connectors (i.e. what's on the RHxx boards, with flat cables going to the adapter to the standard MASSBUS connector, a device rejoicing in the name 'Receptacle Housing Assembly'); the original MASSBUS cables (along with the 'Receptacle Housing Assembly' are now rare as hen's teeth). And there's also the MASSBUS termination... Noel

by jnc＠mercury.lcs.mit.edu

> From: Henk Gooijen > the M7859 is sort of a UNIBUS device. The (front panel) console only > communicates with the M7859. Not quite; it does _mostly_ 'do its thing' over the UNIBUS, but there are also two special lines carried across the DD11-P backplane to the CPU, 'Halt Request' and 'Halt Grant' (which is why it has to be in the same backplane as the CPU); more here: http://gunkies.org/wiki/KY11-LB_Programmer%27s_Console > I cannot remember whether a demux for the displays is on the console > PCB, or on the M7859. I'm not sure exactly what you mean by 'demux', but... the interface between the board and console is i) 3 bits of digit, and ii) 6 individual select lines. Code in the micro on the M7859 sends one digit at a time down the 3 'digit' lines, along with the appropriate 'select' line. > If you get 000000 on the dsipaly and when halted it shows 173066 I > presume it is looping. Well, I haven't looked at the M9312 ROM code, but if it's anything like the M9301 code (which I have dumped and disassembled), looping in the ROM at 173066 is not necessarily bad. There is a listing of some of the ROM code on BitSavers: http://bitsavers.trailing-edge.com/pdf/dec/unibus/K-SP-M9312-0-5_Aug78.pdf but it doesn't seem to cover the stuff at 173000 (which is where the CPU starts running on power-on) - or maybe I just didn't study the listings carefully enough. > If it loops, it will repeatedly read from a device address which is > most likely the CSR of the boot device. Depends on the switch settings on the M9312. If it's set to boot, if the device is there, yes; otherwise it would get a NXM fault. If it's set to go into the console mode, it's probably trying to read characters (commands) >from the console. Noel

> From: John Welch > Can you give me a refresher on how to tell which slots are cut? I > remember having to turn the chassis over and looking for a particular > wire Yeah; you can use the G7273 as a 'crib', since it has the NPG jumper on it. That jumper goes from CA1 to CB1: component side, third connector (counting >from the A connector), first and second pins (again counting from the A connector end). A lot of the slots will still have their jumpers in, which is how you can confirm you're looking at the right pins; look for slots without them. > I also have an 11/04 that I went and drug out. Yeah, the M7263 is the KD11-D CPU, the M7847's are MS11-E's (one of them will be useful as a first-stage debug for the 11/34, once you've verified, in the -11/04, that they work - the M7891 MS11-L is rare and valuable, I'd rather not use that until everything up to that point in the -11/34 is known working - you could try pulling the two M7847's from the -11/04 and try plugging in the M7891, to verify that it's sort of OK). > I am thinking I could put a M9203/M7856 into slot 9, and find a M9312 > for slot 3 and maybe this would fire up. Any suggestions? As always, first pull all the boards and check the power supply (if it's been a long time since it was last powered on, re-form the electrolytics in the power supply first, before powering it on), then put in the _minimal_ set of boards and get those working. > I added an M9302 in Slot9-AB and then moved the M7856 from the 11/34 to > Slot9-CDEF of the 11/04.

Now you have a working machine, you can board-swap in >from the -11/34 to check other boards out. Major, major help!! The first thing I'd try would be the M7859, KY11-LB, from the -11/34 over here. If it doesn't work in the -11/04 (with only that board changed), i) you've isolated the problem, and ii) you can probably use the one from the -11/04 to get the -11/34 working (unless there's something _else_ broken in the -11/34 as well). NOTE: Don't plug the good one from the -11/04 into the -11/34 - or do anything else with the -11/34 - until you've checked the voltages in the -11/34!!! If the M7859, KY11-LB from the -11/34 _does_ work in the -11/04, time to keep looking. The console itself is so dumb it's unlikely to be the problem, but you never know; might we worth swapping. I'm having a hard time seeing what problems in the /34 CPU, etc could cause the symptoms you're seeing - are they still there with only the absolute minimal board set? Noel

Revive 11/34

by jnc＠mercury.lcs.mit.edu

> From: John Welch > Any suggestions as to what to try first? I would _definitely_ start by pulling _all_ the cards you can, to get down to the simplest possible configuration. Once that works, start adding things back in, one at a time. If that configuration doesn't work, first try the obvious things (clean and re-seat, check voltages, etc). If that doesn't get it running, it's time for a oscilloscope or logic analyzer. (We can help you through that.) So I'd start with the CPU (M8266/M8265), front-terminator/bootstrap ROM (M9312), the front console card (M7859), and rear-terminator (M9302) (which you need for grant turnaround, see next paragraph). That's it. IIRC, the /34 will complain if the bus grant chain is not complete (I really need to look at the prints/ucode to understand why this is so - other -11's will run basic functionality fine with an interrupted grant chain), so plug in grant jumpers in every unused slot. Also, check the backplane, to see which slots have had their NPG jumpers pulled, and either i) use a G7273 jumper (the dual boards which contain an NPG jumper as well as the BR jumpers) in those slots, or replace the jumpers. I _think_ the machine will be OK without any memory, but I don't have a running 11/34 to test that on. (Only my /04 is running at the moment.) I can plug my /34 cards in and try it, if that will help. But maybe someone else knows. So maybe you'd have to add a memory card, but that would _definitely_ be the biggest configuration I'd try until the basic machine is working. You can examine the MMU registers in the CPU to check that the bus/console etc are working - first read, then write. And IIRC the CPU general registers are accessible from the bus too - I know they are in the -11/04 (which uses the same front console). Noel

IBM 3270 controller emulation

by charles.unix.pro＠gmail.com

I am trying to wire 3270 support into the DPS8/M emulator. Multics supports 3270 via a bisync connection to the 3270 controller. Multics sends commands to the Front End Network processor, which (originally) passed the commands down the bisync line to the 3270. I have a running Multics and running 3270 display emulators using tn3270 (3270 over telnet), so I need to write the code that maps the Multics commands into 3270 controller commands (and vice versa) and manages the telnet connections to the 3270 display emulators and maps the tn3270 traffic into 3270 controllers. I don't need to actually implement the bisync communications; the controller emulator will be running inside the FNP emulator, but I need to express controller responses to Multics in the bisync format, as Multics is expecting that the responses arrived over a bisync connection. The problem is that I have no idea how the 3270 controllers worked; I've looked through the bitsavers collection; those documents are largely concerned with the displays and tend to treat the controllers as 'black boxes' that just do the right thing. So I am seeking pointers to documentation that will give me a better grasp of the controller functionality and/or discussions with someone who knows how they work..... Thanks, -- Charles

I've seen rust and dust, but there's an old vaxstation II at Goodwill Computers in Austin right now (very cheap, anyone welcome to buy it and get it off my mind) but as most things, I checked out the back and see some circles of white corrosion on the back where the cards? are contacting the case. I don't really have room or time but I don't own anything that uses QBUS or is almost related to some of the neat iron some of you all collect (I've mostly collected way too many home computer history items). Anyway, what is that type of white corrosion on metal? Would one probably assume this means any bus would be corroded and this wouldn't be a computer for the faint of heart hobbyist? I've only seen that maybe from batteries but it's in an unusual place and pattern (I think).

RX02 Difficulties

I wonder if there's a problem with the floppy you are using?

Greetings from Brazil :) Just got a Tandy 1000 SX. Nice shape, but it is missing the ESC and F10 keys. Would someone have a complete assembly (switch + caps) to sell, shipping to Brazil incuided? I'd also be interested in the monitor cable and one or two joysticks. Thanks! Alexandre http://tabajara-labs.blogspot.com

VAX Q-bus identical to PDP-11 Q-bus?

by aaron＠aaronsplace.co.uk

I'm looking after a VAX 4000 for a friend, which has a SCSI Q-bus card (M5976). If the card did not have the large metal face, would it work in a Q-bus PDP-11? We are not going to potentially ruin a card by trying this, but I am interested to know if this is the case. Thanks, Aaron.

Preventing VAX running VMS / Multinet from being used as SMTP relay

by billdegnan＠gmail.com

I have a microvax set up with VMS 5, running MULTINET (and decnet locally). The server has a FQDN and after a while being exposed to the WWW someone out there started using the server as an SMTP relay. I can disable and clear the queue, but I'd like to block entirely this from happening in the first place. I'd like to learn more about how this happens in VMS. Anyone have had this same problem before? I realize back when VMS 5 was current it was not so much of an issue, but today it is. I am working on a solution. I can envision a few ways including blocking the smtp relay port >from the firewall, but if possible I'd like to set up a VMS Multinet solution as a learning exercise. I am open to suggestions, and once I find the solution I'll post it. I understand that this kind of thing is not cookie cutter, there are different levels one could address something like this. I have a comcast business router, and one of the 5 IPs I have is NAT assigned to the internal 10.1.10 port of the microvax. This is the same machine I wrote about previously as with then, thanks for your help. I find the best way to learn is on the actual hardware warts and all. Bill

Playing with HP2640B

by mattislind＠gmail.com

I have been working on a HP 2640B terminal. It was mostly about fixing the "screen mold" problem and cleaning up the liquids that had been seeping out >from the screen down into the bottom. The small coaxial wire that connects the 4.9152 MHz clock signal form the power supply (never seen a crystal controlled SMPSU before!) to the backplane was broken off, but after fixing that the terminal worked fine. Just needed some adjustment to the brightness. With the correct terminfo installed it worked quite well as a serial terminal to a Linux box. Then I tried the short 8008 programs that Christian Corti pointed to http://computermuseum.informatik.uni-stuttgart.de/dev_en/hp2644/diag.html and ftp://computermuseum.informatik.uni-stuttgart.de/hp/hp2644 I tried both a couple of times. The terminal enter the LOADER mode but just hangs completely at the end. I tried different baudrates but no difference. The selftest STATUS line tell me 40<802 which should indicate that there are 4k memory in the terminal. However there should be 5k since there is one 4k board and one combined control store and 1 k RAM board. Maybe there is a fault in the 1k SRAM? The terminal doesn't complain though. Regardless, the programs listed either starts at adress 30000 or 36000 which should then be within the available space. The question is, should these program work for the HP2640B as well? It has a 8008 but my guess is that the firmware is different from the 2644. What is the joint experience regarding this? Has anyone ran these small programs above on a HP2640B? The HP 2640B firmware consists of four EA 4900 ROM chips which annoyingly are not anything like normal EPROMs. So dumping will need special considerations. Has anyone dumped the HP 2640B firmware already? I didn't find it on bitsavers. /Mattis

I was curious to learn I also think, depending on the version of Multinet you are running it should have the option to disable relaying. I know before I installed PMDF (and used Multinet) I was able to do this. process.com (makers of Multinet and PMDF) have really good documentation on their website that you should be able to find the info you seek. In lieu of that, if you're feeling adventerous ... I think I remember you mentioning you were running VMS 5. Would PMDF run on that? (when my Alpha is turned on, currently off as it needs a fan or two) I run PMDF on my Alpha DS10 running OpenVMS 8.3 and I am able to block relaying. Fred

If you are bringing things that are very valuable, you can get a Carnet to temporarily import items to the US and then export them without paying duty. It is sometimes a painful process to find the right person at the airport to stamp the Carnet on the way in and out, and often the customs people have no idea what a Carnet is. The Carnet also costs more than $200 and requires a security deposit based on the value of the item. https://www.export.gov/article?id=ATA-Carnet http://www.uscib.org/ata-carnet-faqs-ud-1675/ -- Michael Thompson

Writeup on Preventing Third-party SMTP Relay MULTINET

by billdegnan＠gmail.com

If anyone is interested, I documented a fairly easy way to prevent third party SMTP relaying with MULTINET 4.1 on a VMS 5 MicroVAX. http://vintagecomputer.net/browse_thread.cfm?id=708 I did cheat a little...I set up an email alias on my modern mail server to forward messages to a single email address on the VAX. This was necessary because otherwise I'd have to have added the mail host ID of every mail server permitted to send email to users on the VAX. Also, I will have to create an alias on the modern mail server for every VAX user who wanted to get mail. I agree ultimately that MULTINET email is too limited, but for my purposes I am satisfied. It's just for the learning experience. Bill
