BBC Master keyboard

by CLeyson＠aol.com

Many thanks for the helpful comments from Pete, Tony and Adrian. Lucky for me I discovered that the terminal pins unscrew. ALL of the keyswitch terminal pins have be cleaned with a mild abrasive (Brasso) and then washed in IPA. I had to remove all of the switches to clean the rust from the frame, but what the hell, they're back to original condition. BTW I don't have any WD40 and would never ever use it on any electrical or mechanical parts - never ever ! Also, as the leaf springs in the key switches are gold plated I've left them 'as is' and not used any propriety "switch cleaners". They should work for another 15 years :-) Also, fixed the intermittent dry joint in the PSU and added the composite video colour mod. Found the last one on the Acorn FTP site http://acorn.riscos.com/documents/appnotes/ This was one of my better buys from Ebay. My only complaint is the tatty case - I will have to think about "re-boxing" it. Perhaps in a 1U 19in case, it will make the connectors a little more accessible and support the weight of the Cumana dual disk drives ! Thanks for the help Chris Chris

E-bay sniping.

by vze2mnvr＠verizon.net

Joe, After reading your three messages, it seems you also see the disparity. There is one point that the author of that page about sniping did not seem to consider. If auctions did automatically extend, but in each extension period, the minimum increment doubled, it could autoextend, yet still come to an end fairly quickly. Because of the sniping issue, I feel that eBay can't really be held as a true measure of the value of things. Only in auctions that had a chance to "settle" at the highest price someone was willing to pay for something, would it be valid measurement tool, of that aspect only of an overall market system, also keeping in mind the terms, i.e. untested, "as-is", tested, guaranteed, etc. The on-line auctions run by the GSA use a proxy bidding system, and also have an autoextend feature. Bear in mind that their prices are not a true measure of actual value either, because some of what they sell is broken damaged stuff, and you don't know what is what until you've bought it. They also don't entertain complaints. Joe wrote: > > Ian, > > I don't like sniping but I understand why it's done.

RT 6150 Lives! (Long!)

by doc＠mdrconsult.com

Meanwhile, back at the ranch.... The IBM RT I was given last weekend turned out to be configured with: Enhanced Advanced 032 processor, which is hardwired with 16MB of RAM. No Advanced Floating-Point Accelerator, drat it all. Extended Monochrome Display adapter (1024x768) w/6155 mono display Ungerman-Bass Baseband [ethernet] adapter Streaming Tape Drive Adapter - RT interface for 6157 1/4 tape drive No tape drive or cable 1 5.25" DSHD floppy drive 3 E70 70MB ESDI hard disks - 2 dead as dirt. 1 SIIG 8-bit Serial/Parallel adapter, c.1998, which prevents booting Keyboard I was able to find archived images of AIX v2.2.1 (which, interestingly enough, I may be able to use *legally*. IBM permits their AIX instructors to run AIX on personal machines for private/non-commercial machines. I'm NOT gonna call Mr. Wolden and ask....) The archive includes VRM, BOS and Extended Utilities, all IBM's updates & patches, the NFS add-ons, man pages (IBM *still* provides the man pages as a separate product!), TCP/IP, and some GNU stuff. And the all-important Diags disk set. NOTE: If you ever have to work on an IBM workstation, as soon as you get the case open, get a paper clip, solder pick, fountain pen, or other not-very-sharp object, and gouge a couple of knuckles with it. Bleeding directly onto the machine is not necessary, but every IBM I've ever worked on required the ritual blood sacrifice before booting. The machine booted to the Diags just fine, after I pulled the serial adapter. There I discovered that the keyboard has several dead keys (well, two, but the Escape key counts triple), that the RT wants <Ctrl>+<Alt>+<Pause> to reboot, and that the display must be powered up before the computer. Everything but the 2 dead E70 drives and the keyboard checked out. There are numerous refernces to the use of IDE drives in the RT newsgroup. Although AIX actually will install in 70MB, it leaves little room to play in. Plus, that one E70 alone was warming my house and whining loudly enough to make my cats cry. Final verdict: they're right, but I saw some glitches I haven't seen documented. You need a "dumb" ISA IDE/floppy controller. It must be set to secondary IDE and primary floppy. Any serial/parallel/game ports will probably have to be disabled. The RT will boot from a secondary IDE controller, if you satisfy the drive specs. On mine, even aftetr removing the ESDI controller, setting the IDE card to primary causes the machine to freeze on boot. Drive specs: A Seagate Medalist IDE drive. Period. Some posts suggest that small Quantum or Conner drives will work, but not boot. The WD, Quantum, and Maxtor drives I tried weren't detected at all. The Conner 340MB was detected and passed, but I haven't tried booting it. The Seagate ST3250A Medalist is booting quite nicely as hd(1,0). I did try an ST32122A 2G, and it installed OK and booted fine once. After that, it drops into maintenance mode on boot, with unrecoverable errors. Mount claims that the filesystem devices don't exist. I'm not convinced that wasn't due to operator error during install. Still to do: Find vi. I haven't installed the Extended set yet. Please Gods don't make me use ed. Set up TCP/IP networking. Just got the TCP/IP set installed last night, and configuration is waiting on vi. I hope. I've been offered a copy of 4.4BSD/Romp for it, which I may try out. I'd like to try AOS, but I can't find the full distribution, just the tools, updates, and diagnostic utilities. Find a mouse. Suck it up, gird my loins, and try repairing the keyboard. I may try using stty to remap the dead keys till I have a backup kbd. Yee-Haw. I now have AIX v2.2.1, toys, tools & updates, on 5.25 floppy!

Bell & Howell Apple II update

by mythtech＠Mac.com

>My little U-matic portable (The front says JVC, the service manual says >Hitachi...) has SO239 socket ('UHF') for the composite video input and >output. It's a 625 line PAL machine, of course -- I have no idea what the >NTSC version uses.... My UMatic experience is really limited to just Panasonic and Sony units (dating from mid-late 70's thru my newest Sony is maybe 10 years old now). But interestingly... I was wrong... I HAVE seen the "UHF" connector for composite. I had completely forgotten about the old closed circuit video system I pulled out when I started working at my current job. They had 3 black and white security cameras that used that connector. I know they were composite video, because I remember using an RCA adaptor, and connecting one to a VCR's video line in shortly after pulling them out of service. So yeah... I have actually seen that setup, I had just forgotten about it, as it might have been the only place I have seen that (but also, 90% of my AV experience is from mid 80's to mid-late 90's, so most of what I was exposed to is the "current standards" connectors). That's why I disclaimed that I wasn't saying it didn't exist... just that I hadn't seen it (I have also learned in A/V, if there is a connector out there, odds are, someone, at sometime, used it in their setup) -chris <http://www.mythtech.net>

WTH is this?

by rigdonj＠cfl.rr.com

Does anyone have any idea what this card is for? <http://www.classiccmp.org/hp/mds-80/analog-d.jpg> When I picked it up I thought it was a Multibus card but a closer look reveals that it's (1) too tall, (2) too narrow, (3) The large connector at the bottom has 100 contacts instead of 86, (4) the narrow connector has 40 pins instead of 60 and it sticks down too far. Any ideas? Joe

I need PDP-11/34A Help Again (Suprise Suprise)

by Andreas.Freiherr＠Vishay.com

Owen, still interested in getting your PDP-11/34 to work? - I am just about to reassemble mine after relocation. RUN light off and display 000002 means the processor halted at memory location 2, so it has probably executed a HALT instruction (opcode 000000) from location 0. Try this: while holding the CNTRL button, press BOOT. This should launch the program from your ROM. Depending on which type you have (look for modules labeled M9301 or M9312 in slot 3 or 4, whatever is next to the processor), your milage may vary here. The console terminal should print four numbers in octal, followed by an "@" or a "$" as a prompt in a new line ("Dave, my mind is going..."). Depending on the ROM, you may need to enter either 773000G (standard start address and GO command, pressing the return key is _not_ required here) or a two-letter device code to boot. The bootstrap module may also be wired to boot from a predetermined device without asking. BTW: The DL11-W has 20mA drivers as well as RS-232. (Note the "1488" and "1489" chips being present as well as a number of transistors and other discrete components.) Which set is used depends on the cable: the plug will have some wire connections to code it for either 20mA current loop or RS-232 / V.24. If you have the original cable with the usual DB-25 connector, it should be OK: current loop used a completely different 6-pin "Mate-n-Lock" connector. For the settings at the terminal, I don't know your particular type, but with most DEC lines you should be best prepared if you use XON/XOFF handshake (for "Main Rcv Hndsk" / "Main Xmt Hdsk"). Since at PDP-11 times, the 8th bit was commonly used as a parity bit, set your terminal to ignore this. Otherwise, you may get garbage characters instead of about every second readable character. We may get this straight later, when we know what operating system you have. A RS-232 break signal can sometimes cause a PDP-11 to HALT (depending on settings on the DL11-W board), so you may want to avoid this... (perhaps by choosing an appropriate setting for the "Disconnect" option for now?) So much from memory. If you need more details, let me know, and I'll dig into the docs. Good luck, Andreas -- Andreas Freiherr Vishay Semiconductor GmbH, Heilbronn, Germany http://www.vishay.com

OT: Pricing (was RE: Microdata "Microprogramming Handbook")

by Robert_Feldman＠jdedwards.com

NCD 88k xterm info anyone?

by claudew＠videotron.ca

Hello from mild and almost snowless Montreal... A recent find for $5. NCD 88k xterm, no keyboard, no ram, no monitor... Very little help on the web about this. I wanna try this out, I am not sure why... Anyways who knows the ram simms specs and where they go in this thing (unit came with no ram) I managed to get some "normal reaction" by putting a 1M simm in the inner most simm socket and 2 X 4M simms in the outter most sockets. I am saying "normal reaction" cause I have still not found a monitor that will produce stable output on this thing. I do see somekinda "unsync-ed" POST and looks like text appearing and scrolling on screen every approx 5 secs, imagine the term is looking to boot from somewhere... Who can tell me more about the video output specs? Looks like mono and my pinout seems ok 15,16,17 R,G,B and 26 TTL Vsync and 18 TTL Hsync from looking at it with a scope... Any help appreciated...

AT&T hardware

by xds_sigma7＠hotmail.com

Pat, Unless you have a need to control a bunch of 3270-emulating terminals, a 6544 isn't a terrible useful thing to have. It's basically a non-IBM version of a 3174, etc., which is a unit used to hook up many terminals to your 3270-protocol host computer, be it mainframe or minicomputer. I don't know what terminals the thing is meant for, since it beats me if AT&T's terminals support 3270, but they probably do, though I'd imagine it doesn't use coax.. Which, if that is true, might limit you to using AT&T terminals with it, which is kinda crappy.. Hope that helps some Will J _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com

UofM Property Disposition

by root＠diablonet.net

Hi everyone! I went to the University of Michigan Property Dispotition warehouse today, and I've got a couple of questions and other related things to say. 1. To the couple of people who asked me about the NeXTDimension Cube that was there last month, my apologies, but someone else got to it before I could. 2. I saw a DEC pedestal cabinet there that looked exactly like a VAX 4000 series machine, but it was just labeled "R 4000". I'm assuming this was some sort of VAX, and there seems to have been a thread on the NetBSD/vax mailing list about it a while back, but since their mailing list archive server seems to be down at the moment, can anyone tell me more about this machine? I'm a bit curious as to what it is. 3. There was an interesting looking Evans & Sutherland computer there labeled as an ES-3. I popped the front cover off of it and it looked relatively sophisticated, but I didn't actually pull any boards and get a good look at them since they don't like people doing that sort of thing there at the warehouse. I read somewhere that this box runs UNIX and had some pretty nice graphics capabilities for its time. Does anyone know much about these (e.g. architechture, history, OS specifics, etc)? Does anyone know how they stacked up to SGIs of the era and similar competing machines? The thing's kind of heavy and transportation to and from the warehouse is pretty evil for me, but if its a really nifty machine, I'd like to save it (I've certainly never seen one before). Unfortunately there didn't seem to be any monitor, keyboard, or mouse included with it. Does anyone know any specifics about these either? Hmmm... other oddiments there that were kind of interesting included a dual 8" Data General floppy disk drive, an old SGI POWER SERIES Twin Tower machine, and probably some other stuff that I'm forgetting. Just thought I'd mention them in case someone lived in the area and was interested in taking a look.

IBM 3151 terminals (Which keyboard?)

by csmith＠amdocs.com

I've recently received a small pile of IBM 3151 terminals. All seem functional. I also have a pile of IBM keyboards, some of which look like they may fit the terminals. The two keyboard types of interest (IE the ones with modular plugs) are: A model "1397952" -- this one has an 8-wire modular plug. When plugged into one of the terminals, it will say something on the order of "PROBLEM IN KEYBOARD" A keyboard that's not clearly marked at all, but the longest identifier-looking number on the tag is 122RK33S(or 5)-30S(or 5)E-J. This has (I think) a 6-wire modular plug. It has a panel of dip switches near where the cord connects. When plugged in this one reports the (more interesting) error of "PROBLEM IN VIDEO ELEMENT OR KEYBOARD" (My guess it it's in the keyboard...) Both keyboards have 24 "function" keys, and a panel of odd keys to the left of the alpha section. So does anyone know what these particular keyboards actually go with? Can I maybe change the switch settings in the latter keyboard, and get it to work with these terminals? Does anyone know what the switches even do? Why don't the terminals report odd numeric errors? "PROBLEM IN KEYBOARD" is almost understandable ;) Regards, Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

IBM 3101 Dip Switches Configuration

by spedraja＠ono.com

Hello. I have one IBM 3101 ascii terminal ready to be used connected with one serial cable to one Linux system that I have by the serial port 2. The inittab has uncommented the line referred to the ttyS1, and appears to be correct because one "ps -ef" shows the "/sbin/agetty ttyS1" line with the "[login]" comment. The problem is that the IBM 3101 don't establish communication with the Linux system. The 3101 show one "Line Check 2" message that talk about the comm.line, I suppose. The cable used is one normal serial cable. The 3101 has some dip switches in the upper of the keyboard. If they are taked, the Line Check 2 message dissapears and the screen is filled with "?" signs continuously. It's clear that some options can be configured with this method. Somebody has some more deep info about this terminal ? Must I use one special serial cable ? Thanks and Greetings Sergio

FreeVMS

by msell＠ontimesupport.com

I know I'm going to open up a can of worms on this post, but my curiosity is killing me.... Now that I have OpenVMS 6.1 running on my VAX 4000, I'm curious about the status of the various "FreeVMS" projects that are in progress (or so it would seem....). Are any of these projects really in active development? Which projects have the greatest potential for operation? I checked several sites related to "FreeVMS", which actually seems to be a common name for several different projects with different goals. I'd love to "cut my teeth" with kernel development after working with Linux for several years. I personally think it would be neat to have an accurate version of FreeVMS that would work on VAX, AXP, and i386 (gulp!). When I say accurate, I mean that FreeVMS would respond the same as VMS would for the various commands and peripherals. Some of you probably think it would be silly to take an i386 version of FreeVMS and port it "back" to VAX and AXP, but it would be a neat way to use FreeVMS, especially if the OpenVMS hobbyist program (or OpenVMS) were to go away. Nuts? Probably. Neat? Yes! Here are links to the various FreeVMS projects I have visited: http://www.panix.com/~kingdon/free-vms.html http://www.freevms.org/ http://www.djesys.com/vms/freevms/ - Matt Matthew Sell Programmer On Time Support, Inc. www.ontimesupport.com (281) 296-6066 Join the Metrology Software discussion group METLIST! http://www.ontimesupport.com/cgi-bin/mojo/mojo.cgi "One World, One Web, One Program" - Microsoft Promotional Ad "Ein Volk, Ein Reich, Ein Fuhrer" - Adolf Hitler Many thanks for this tagline to a fellow RGVAC'er...

BBC Master keyboard

My question is - > > Am I correct in thinking that all the keys need to unsoldered from the PCB, > and are the key contacts easy to get at and clean ? Whether you need to unsolder all the keyswitches depends on the keyboard -- there were 4 types, but only one -- fortunately the least common type -- needs much work. The best, and original, was the type using Futaba keyswitches, which have a white body. These are easy to remove, one at a time (desolder the connections, then release the clips which hold the keyswitch in the frame). I've seen a couple of pictures on the web showing the different types but I can't seem to find one right now :-( The normal way to fix faulty ones was to replace them. You can still sometimes find switches available from people who've dismantled machines. If not, I'd try removing the faulty keyswitches and cleaning them by swishing them in a small bowl of iso-propyl alcohol, or squirting IPA followed by switch cleaner through them. Finish with a good-quality low-residue switch cleaner. These are generally based on IPA with small amounts of very light oil (not usually silicone, as it creeps too much and gets into everything). Do not use anything like WD40! -- Pete Peter Turnbull Network Manager University of York

I think it might have had more to do with what kind of single was being sent. (at least in the video industry) My old UMatic decks from the 70s have either "UHF" connectors (PL-259), or F connectors (depending on age) for all the modulated signals (connects to a TV shows on either channel 3/4 or 6), but all the ones that have composite signals (non-modulated, needs a "line in") have either BNC or RCA (depending on quality, doesn't seem to have bearing on age... higher quality decks have the BNC for video, RCA for audio, and lower quality have the RCA for video and audio). I don't think I have ever seen a "UHF" (PL-259) or F connector on a non modulated composite signal (not saying they don't exist, just I have never seen them), same with I don't think I have ever seen a BNC or RCA on a modulated signal. -chris <http://www.mythtech.net>

Did a quick search with Goolge and found a few tips on BBC keyboard repair. It seems I have a type I keyboard with Futaba keyswitches fitted. They come out of the frame one at a time. After a bit of fiddling I discovered that the keyswitch body is held together by a small plastic clip and two screws. The terminal pins are the screws and can be removed by gently rotating with a pair of pliers. Terminal pins are silver plated and show signs of tarnishing on the faulty keyswitches. The contact leaf springs appear to be OK. A mild abrasive and some IPA should do the trick :-) Just wish I'd kept that Cherry keyboard form years ago with the Hall effect switches. Chris
