CDC 924 console in 'The Terminator' (fwd)

However, the machine (like the 1604) was originally marketed with Ampex tapedrives, generally the vacuum-column versions although the torsion-arm versions were also used (the model numbers escape me at the moment, but in the case of the 1604 I believe the 4-drive chassis was the 1605). This photo is of a newer configuration, probably circa 1963. I remember some indications that the 1604 and 924 were prototyped in 58-59 and the 1604 first delivered to the Navy in 1960. Our 160 reference manual (first printing with the blue/white color scheme) is dated 1959.

Needed / Available

by edick＠idcomm.com

Well . . . what I meant was the monitors. That's what he's asking $75 for and without the Appollo stations they're of little use, being fixed frequency types. If he asked $25 for them they'd still be difficult to move. I don't see that the monitors have much value as scrap. Unfortunately, in one localized area, there's not such a concentration of "old-computer" fanatics to provide homes for all of them. The fact that they all work has clouded the vision of the shop owner, and the fact that he doesn't have root passwords, etc, needed to take control of them makes them of little interest to potential users, even though it does seem to show that they're working machines. Besides, for a couple of hundred bucks one gets a P-II or something like that with no real effort required to make it work. They'll end up as scrap.

When I was 13/14 years old (don't remember the year) I pulled out the board and the connector broke in half. The connector wires with ends popped out so I had to reconstruct the connector. I asked my dad for some serious adhesive they use at his work place (steel). He brought it home and I slowly but carefully glued back in each wire into the connector and finally glued the connector back together (about 15 minutes close work). I got quite dizzy after a while and stopped working on it. What I didn't know was this particular chemical had sodium cyanide in it. That night I got dizzy, headaches, threw up.. The next morning huge sores were in my mouth, throat, tubes, etc... By about noon the next day I was in the hospital. I had close direct exposure to the chemical without any ventilation. The doctior did say a couple more minutes of use and I would have dies as it would have scarred my lungs. The hospital could do nothing and I suffered in amazing pain for a week. Worst pain was at night,... if I swallowed in my sleep I would wake up as the scarred tissue would open in my throat causing unbelievable pain. I have followed warnings on the bottles ever since. The doctor did tell me that they had one case like that years ago when shoemakers use to use that kind of chemical to fix shoes. Not fun. BTW The supply did work and I still have it. >pbboy > >

Spotting MMJ connectors (Re: Needed / Available)

Another source for the crimper and connectors is Altex Computers & Electronics. www.altex.com In last year's catalog Crimper - Stock no 60-3008, $38.59 Connectors - Stock no MP-6D, $31.00/hundred They also have adapter kits for MMJ to 9 and 25 pin D connectors for $4.50. A couple of the 9 pin adapter kits might come in handy. I assume, being a kit, that it comes with the D connector pins uninstalled so you can roll your own. I say handy because DEC's The H8571-B MMJ to DE9 (female) adapter is not wired correctly for a typical PC 9-pin serial port. I always have to hunt down one of my MMJ to DB25 adapters and then a 25 to 9 pin adapter. ----- In any event, I just recently updated a mini-FAQ on DEC's MMJ. So FWIW, here is a copy of it. Mike Info on the MMJ connector found on various DEC terminals & computers. --------------- --------------- --------------- --------------- --------------- DEC uses an MMJ (Modified Modular Jack) connector on its equipment for serial data communications. DEC calls the mating plug on the cable an MMP (Modified Modular Plug), only the term is not used as often and most of the time is just simply referred to as MMJ. It is like a modular telephone connector, only the key on the connector is offset, not in the center like a standard telco connector. Looking at the back of a VT320 for example the MMJ looks something like this. -------------------- | * * * * * * | -------------- -- |____| 1 2 3 4 5 6 are the pinout numbers --------------- --------------- --------------- --------------- --------------- The signals are: # I/0 Desc 1 > DTR Data Terminal Ready 2 > TXD Transmit Data 3 - TXD- (ie Gnd) 4 - RXD- (ie Gnd) 5 < RXD Receive Data 6 < DSR Data Set Ready > = terminal or computer output signal < = terminal or computer input signal --------------- --------------- --------------- --------------- --------------- DEC's part number for the cable is BC16E-xx, I assume the xx may be the length. The cable is made so that the connector on one end is mounted 'right side up' and the other end 'upside down'. In other words, the key tabs on the connector are on opposite sides of the flat cable. // ---- ---- | |---------------------------------------| | ---- ---- // That is effect causes the signal lines to cross-connect or as I like to say 'turn over' from one end to the other. MMJ port on DEC MMJ port on DEC VT320 terminal computer or DECserver DTR 1 --->-------------->----------------->--- 6 DSR TXD 2 --->-------------->----------------->--- 5 RXD 3 ---------------------------------------- 4 4 ---------------------------------------- 3 RXD 5 ---<--------------<-----------------<--- 2 TXD DSR 6 ---<--------------<-----------------<--- 1 DTR --------------- --------------- --------------- --------------- --------------- I had a DEC MMP cable that someone cut one end off so I wired it to a female 9-pin D connector to use with a PC 9-pin serial port. Wired as follows: MMJ DE9 1 6 2 2 3 5 4 5 5 3 6 4 This was to use a PC as the console on a DECsystem 5500 and/or one of the ports on a DECstation 3100. I actually did not connect DE9-6 to MMJ-1. It worked fine without it. I later made a breakout box with two 9 pin D connectors and an MMJ socket along with the means to disconnect and rewire as needed. I found that it works fine without DE9-4 being wired to MMJ-6. In other words, using only the two data lines and ground. Your mileage may vary, depending on how things are setup. --------------- --------------- --------------- --------------- --------------- DEC makes several adapters to adapt the MMJ to 9/25-pin D connectors. The H8571-A and H8575-A are MMJ to DB25 (female) and are wired as follows: MMJ DB25 1 20 2 2 3 7 4 7 5 3 6 6 & 8 Also pins 4 & 5 of the DB25 are tied together I have used the above using a standard DEC MMP cable to connect to a PC 25-pin serial port to use the PC as a terminal. --------------- The H8571-C and H8571-F are MMJ to DB25 (male) and are wired as follows: MMJ DB25 1 6 2 3 3 7 4 7 5 2 6 20 --------------- The H8571-B an MMJ to DE9 (female) and is supposedly wired as follows: MMJ DE9 1 5 2 2 3 7 4 7 5 3 6 6 & maybe 8 (depending on which DEC manual you read) I have never seen one, so have not actually checked how it is wired. It should be noted that this is not wired correctly for PC 9-pin serial ports, besides the gender of the 9-pin connector is wrong. DEC says that this is used for connecting to 9-pin printer ports. --------------- --------------- --------------- --------------- --------------- And here is a summary on how the various signal lines match up to each other on the different connectors.

AT&T PC 6300 Plus Unix box

by kees.stravers＠iae.nl

On Sun, 3 Oct 1999 19:25:40 -0400 (EDT), Bill Yakowenko said: >What makes you think it is a 6286EL? I know next to nothing >about these AT&T boxes, so I never would have guessed anything >besides what it says on the label. Is it just because it's a >286 box? It quite definitely says "6300 PLUS" on the machine >itself and on all of the floppies that I got with it. I have been reading this 6300 discussion for a while, but I still don't know which computer exactly this is. I know the Italian firm Olivetti built the 6300 series for AT&T, just like they built a number of DECpc's for Digital. I only know the original Olivetti's, and can't determine which Olivetti hides behind the 6300 label. The standard 286 Olivetti clone systems I have used, always complained about a parity error if there was RAM memory removed from the system and this was not updated in the cmos setup. The machine would count through the memory that was there and generate the error when it fell off the end. Updating the cmos or adding memory might work. If your 6300 is a 8086 or 8088 then it will not be a standard clone, Olivetti did things their own way in those days and you will really need a manual (which I don't have, the first Olivetti's I met were the 286's). If it is a 286 Olivetti, then there is no key sequence to get into the bios setup screen. You need a setup floppy. Some 286 Olivetti's do have an rudimentary internal setup program, but that only comes up when there is a problem. To get into that setup I used to unplug the floppy drive power cable. Even for the 486 Olivetti's a setup floppy was always needed to get at all the bios setup options. This has always been quite a pain, since there is no universal Olivetti setup program, each machine has its own. The exchange program between AT&T and Olivetti also worked the other way around. I have a 3B2/400 Unix system in my collection (in a part of the Computer Home I haven't photographed yet, so no picture, sorry) that has the Olivetti label on it. I don't dare to use it because I don't know the password, and I do not have any floppies or tapes with the Unix OS for it, so messing it up would be unrepairable. Besides, AT&T wants a great deal of money for the maintenance floppies. This machine will alwas have a special place in my collection though, since it is so heavy I sprained a muscle in my back while lifting it so bad that I needed several weeks of therapy to cure.

What's the best RS-232 terminal?

>But if you want to actually run them turned on when they are even two >high, other than a VT100 (which is what I still use for the first level), I >have not found another terminal (except for VT100 clones) which allows >stacking. The VT52 stacks really well, as does the H19. It's also possible to unbolt the keyboard from an H19 and replace the cable with a really long one, which gives you a detached keyboard to set on your lap and a handy shelf for storing it on when you're not using it. I once had a setup with six VT52s (two piles containing three VT52s each). I foolishly built the pile right underneath the thermal cutoff for the computer room power, so I wound up having to move it.

CDC 924 console in 'The Terminator'

by msg＠computerpro.com

Greetings again! Having not seen the film 'The Terminator' until a few days ago (on The SciFi Channel)... I know, I live in a cave, I was very surprised to see a CDC 924 (or 924A ?) console, complete with Ferranti photo tape reader evidently hooked-up in some fashion to illuminate the rear- projection register and status displays. The scene is in the factory populated with assembly robots towards the film's climax. I have only seen one other 924 console (in person) in about 1975 at an electronics surplus salvage yard in the San Fernando Valley, where it was being used as a workbench! IIRC, there were only about two dozen 924s made. It was a 24bit version of the 48bit 1604, CDC's debut commercial product in 1957-58. Does anyone have a handle on film industry computer archaeology, perhaps contacts at studios or property shops? For years I've been meaning to pursue this venue but alas... I've been compiling lists of film and television shows which showcase important computer artifacts (one would be surprised at the variety of significant hardware in 1950-60's TV, especially sci-fi anthology series. Any additions to these lists would be appreciated. In addition, we seek newsreel, scholastic and training films which highlight important information technology (I wish I had followed school district auctions in the early 1980's when all those 16mm films of MIT Whirlwind, AN-FSQ/17 Sage, Bendix G-15 Redstone launch control and the like were discarded.

Mitsubishi monitor

by wrm＠ccii.co.za

Hi all I came across a large, heavy Mitsubishi monitor, C-3910ELP, manufactured in September 1980. I want to use it as a display for MAME (arcade game emulator) in 288x224 mode (NTSC or PAL-type timing), but I can't get the thing to sync on such a signal. The monitor has *lots* of pots for setting who-knows-what, and many many jumpers. Somebody might have fiddled with it before as well. So, anybody know anything about this beast? I can put up pictures if required. Thanks Wouter

Amiga World magazines

by yakowenk＠cs.unc.edu

I've got a small pile of Amiga magazines available. The pile contains most issues from 1991 through and including 1994, plus a couple issues outside of that range. There are also about a year's worth of Amiga Computing magazine which seem to be from 1995 and 1996, but sport a bewildering variety of issue numbers and dates, with very few having both an issue number AND a date, and with issue 2 following issue 87 (those two had both)... Make offers. If the highest valid offer is less than double the lowest one, the first one to arrive is the one that wins. The intent is FCFS unless somebody really _REALLY_ wants them. Valid offers are those that meet or exceed the cost of postage. :-) I'll wait until noon on Thursday to decide. You could also look at my "wanted" web page and offer things from there, in which case I'll have to decide whether I'd rather have that or the money: http://www.cs.unc.edu/~yakowenk/classiccmp/wanted.html Cheers, Bill.

by edick＠idcomm.com

That is a VERY reasonable thing to ask! It's in Denver, and Emanuel Stiebler has expressed interest (he's local) so he'll probably get here first. The experience I have with Apollo monitors for, among others, their 2000-series stations is that they had monitors which were very nice for the time, and worked at 1024x800. These worked fine with a modified SVGA board. There's a local surplus guy who's got about a half dozen Appollo stations with the HP label on them and with HP monitors which he's trying to sell for $75. I doubt he'll sell even one.

Mailing list suggestions

by msg＠computerpro.com

Greetings. I have found the traffic on this list invaluable and someday when I have the drive space and a highspeed link I'll download the archives :-) In the meantime I'd like to suggest a splitting of the list into two streams to permit a useful lower bandwidth subscription and still allow for the chattier subscribers to freely communicate. The lower bandwidth list could be dedicated to buy/sell notices and alerts and moderated Q&A (perhaps the latter culled from the freeform list). When I first subscribed I tried to read every post and reply but soon fell behind (there's only so much time at the keyboard) so I decided to maintain and archive and do keyword searches on it. If this topic has been covered please accept my apology. Michael Grigoni Cybertheque Museum

Radio Shack DT-1?

by yakowenk＠cs.unc.edu

Anybody out there know about the old Radio Shack DT-1 terminal? Somebody over on the "Obsolete Computer Helpline" was looking for info on how to configure it (it can apparently emulate a few other kinds of terminals) and what the connectors are for (there is a ribbon-cable connector on the bottom in addition to the obvious serial connector on the back.) Also, what was the name that Radio Shack gave to the re-badged Wyse that they were selling once upon a time? Bill. PS. I'm not nominating the DT-1 for best RS-232 terminal. :-)

How on earth do you align an RX50?

Your committed, or maybe should be. ;) seriously, two most common problems is motors (communtator/brush wear and bearing out of round) and in ability to get the top and bottom disks to calibrate on track.

Board ID : Plessey PM DCV51?

by cmcmanis＠freegate.com

Does anyone have any information on a Plessy board model number PM DCV51? It appears to be a disk controller one 34 pin connector and four 20 pin connectors. It has plastic handles on the ends like a QBUS board. (I suppose it could also be a quad wide unibus board but I don't think so.) Markings on one of the chips is: P/N 706131-1001B S/N S-179 1/5/87 Model PM DCV51 (could be OCV51 the D and O are hard to tell) There is a NEC D7261AD chip on the top, an uncovered EPROM (worrisome), several PALs and a large chip (68pin DIP) labelled AM29x305 Anyone? --Chuck

MIPS Magnum 3000 questions

by rdd＠smarty.smart.net

Greetings, Yesterday, I acquired a MIPS Magnum 3000; no display, no mouse; just the keyboard. Can this system be used from a serial port or ethernet with no monitor or mouse attached? If the system's bootable, can anyone tell me if there's a somewhat easy way, specific to this system, to gain root access, from the console, without having access to a bootable tape? Alternately, can anyone point me in the direction of a boot tape for this machine, and a source of documentation for it? Any other information, such as specifications, etc., pertaining to this machine, would also be greatly appreciated. -- R. D. Davis rdd(a)perqlogic.com Be careful what you wish for --- you http://www.perqlogic.com/rdd may get your wish ...and it might not Tel: (410) 744-4900 be what you were expecting.

What's the best RS-232 terminal?

by IVIE＠cc.usu.edu

> Anybody have a favorite? Why? My favorites are: Heath H-19, DEC VT-52, and DEC VT-220. Unfavorites are: - VT-100. It just doesn't have enough compute power. Since I'm a CP/M WordStar fanatic, requiring XON/XOFF on the console port because the terminal is underpowered is very annoying (^Q and ^S are very important keys in WordStarland). - Anything by Televideo. Televideo keyboards and I don't get along. The touch is too heavy. I press CONTROL [ for escape because I use so many different keyboards and that moves around less than the ESC key, but the Televideo terminals insist on sending ^] no matter how I'm holding the shift key down. - Terminal emulators running on PCs. Seems like there's always some annoying quirk they get wrong. For example, MS-DOS KERMIT didn't play nice with K52 on RT-11 because K52 likes to move the cursor to the 25th line if it decides not to move the cursor at all; a real VT-52 doesn't have a 25th line, but KERMIT does. Another example: PCCONS under NetBSD goes into graphics mode the first time I telnet into a VMS machine to read my mail. I don't know why. Roger Ivie ivie(a)cc.usu.edu

ISA expansion boards/cases

by mid＠auk.cx

Is there a good place to find boards that plug into a 16bit ISA slot and let you have another 8 or so slots? (without building your own) I would think there'd be a fair number of these floating around now that ISA is nearly dead in the mainstream, but aparently not. The cheapest I saw one new for $496. Bit ridiculous, imho. All I need is both end-boards (host end and backplane end) and a backplane. (I certainly don't need anymore cases...) Can anyone help? af --- Adam Fritzler { mid(a)auk.cx, afritz(a)iname.com} http://www.auk.cx/~mid/ "Something in my systray is blinking wildly." -- DS

The Day's Finds

by healyzh＠aracnet.com

Today was a good day, as it was the Fall CP/M Users Group Swap Meet. I managed to get a PDP-11/23+ in a nice BA23 chassis, though not sure that counts since I'd arranged to pick the system up there, as I don't have a lot of time at the moment. He wanted to keep the 1Mb RAM board, which wasn't a big deal for me, especially as it still has 2 128k RAM boards. More importantly it's got the RL02 controller I needed. I stocked up on small SCSI Hard drives, I'm no longer worried about not having enough drives in the 100-200MB range :^) Got a HP LaserJet ethernet card, but it turns out I got my model mixed up with another :^( BUT the find of the day was the AIM 65, still in the original box and packing material with what I assume is all the paperwork/papers. The only downside is the plastic over the LED display is cracked. It's got the printer on the board, and a roll of paper even. Now I just need to find out what an AIM 65 is! Zane | Zane H.

What's the best RS-232 terminal?

by fmc＠reanimators.org

"Mike" <dogas(a)leading.net> wrote: > Anybody have a favorite? Why? Several. If I want a small, light VT100-like terminal that's easy to move and doesn't take up a lot of space, I use an HP200LX palmtop PC. Why? Because it's there. I use it heavily anyway, and the serial cable and adapter bits are usually not too far away if I'm at home or the office. If I want something with HP terminal emulation or something closer to a real keyboard, I use one of a couple HP Portable Plus systems that I have around with WRQ's Reflection in ROM. Guess I could find a copy of Reflection for DOS and install it on the 200LX but I haven't. If I want something that looks like a terminal, the HP 2382 is nice because it's small and light. If I wanted a printing terminal, I'd probably pull one of the newer, smaller TI Silent 700s out of storage and use that. Or I have a 3M Whisper Writer stashed somewhere in the car right now. Just drop in a roll of FAX paper and I'd be ready to go, and again they're fairly small and light. Of course FAX paper isn't really good as a long-term storage medium, you need a plain-paper printer for that. For just plain neat-o keen-o terminals, there are the HP 264X series of terminals. They don't emulate DEC VT-anything but who cares, if you have a 2645 or 2648 (maybe a 2641 too, not sure) there's an 8080 in there and there are games that can be downloaded to run in the terminal. It's also amusing to note that the display memory isn't fixed as a number of rows of characters -- the displayed text is actually stored as a linked list of 16?-byte chunks, so you can have lots of short lines or fewer long ones, and it's easy to scroll the display window through memory. -Frank McConnell

Does Microsoft windows use some sort of unusual ASCII? It's not ASCII, it's using characters in the range 128-255, which in the original PC include line drawing characters. You can download a character set with the line drawing chracters for Windows by following the link near the top of each of Seagate's spec pages. Eg, on http://www.seagate.com/support/disc/specs/st41200n.shtml, there's a line with two links: "Odd characters? _Click_here_for_help_. A version of this specification with the linedraw characters approximated by text is available by _clicking_here_." The first link takes you to a help page for Windoze users, the second takes you to a CGI program that fetches the flat-ASCII version from Seagate's FTP site, ftp://ftp.seagate.com/techsuppt/scsi/st41200n.txt Another way to deal with the problem (if you're using X Windows) is to find and install a font with the line drawing characters. There's one called vga.pcf.Z floating around the web somewhere. -- Pete Peter Turnbull Dept. of Computer Science University of York

Getting a Sun 4/110 to boot

by rdd＠smarty.smart.net

Greetings, After changing removing a jumper on my Sun 4/110's boot drive *running Solaris 2.4)so that it spins up with no motor control, I still can't get the system to boot from the CD-ROM as I did in the past when I originally installed the OS. I've disconnected all other hard drives and tape drives, so it's just the one hard drive and CD-ROM. The hard drive is SCSI ID 0, with terminating resistors, no parity, as it was before. The CD-ROM is SCSI ID 6, no parity (Toshiba XM-4101B). The hard drive was bootable, although it had lots of errors reported by fsck; when I ran fsck manually, I made a mistake that resulted in "device not found" when attempting to boot the system. Simple to fix, I thought... just reinstall the OS from CD-ROM as an "upgrade," thus preserving data on the drive (am I right about this part?). When I attempted to boot from the CD-ROM, b sd(0,6,n) and b sd(0,31,n) where I tried 0, 1 and 2 for n, the system tries to access the hard drive, as I can hear it trying to do so, in addition to the CD-ROM making a noise. Then, the following error message appears: sd: sense key=5 error=25, block 0 [repeated over and over, then:] Waiting for disk to spin up {and tells me to start it if necessary] Please start it, if necessary, -OR- press any key to quit sd: sense key=5 error=25, block 0 [keeps being repeated] Does anyone have any idea or suggestions? The next thing I'm going to try is to install another hard drive and try to install Solaris on it, but it seems to me that if I could boot from the present drive before the fsck mess, I should still be able to boot from the CD-ROM with that installed. Is there something I'm overlooking? -- R. D.
