This might have been before your time, but I might as well ask: > got any stories to tell about the Hazeltine 2000? Back in the 70's when I was in college (WPI), our computer center used a bunch of HZ2000s at the center itself. (our system at the time was a KA based PDP-10). An oddity of the TOPS10 monitor (or at least the version that we were running) was that it let people send messages between terminals even if no one was logged in. One of my friends figured out that if you opened an unassigned terminal in the computer center (usually after hours)from a remote campus site, you could dump a series of commands (usually including "send" commands :-) to the HZ2000, terminated with a "send screen" command sequence. This let you send messages that looked as if they originated from the center to another remote terminal.(Heck, we were just college kids, and it was an innocuous bug. Boy, I miss those days :-). -al- > > I ran across a few of them in the early 1980s, being used as 1200 bps > terminals to a Univac 1108. 74-column green-screens in yellow-painted > metal boxes.

I'm depressed, I was just trying to lookup some info using DejaNews, and couldn't get it to dredge up anything older than about a month ago. Now I know why, they've taken the archives offline, and are apparently moving thier servers to a new site. Between the 20th-26th the stuff from two weeks to a year ago will be unavailable.

Identification request - QuadexQ5000/SMS/Compugraphics/DEC ??? should I save it?

by west＠tseinc.com

A friend called me about a cpu cabinet sitting next to a dumpster. I would like some background and identification on this system if anyone knows. And most importantly - there's much more that I left behind - should I go get it (as in anyone here want some of it)? At first blush I didn't think it would be interesting, but it looks like an unibus system; it also had some M8043 and M8017 cards in it so it must be something DECish? Here's very sketchy details... Quadex Q5000 labeled rack and cpu enclosure Various tags inside the cabinet mention Quadex or Scientific Micro Systems or CompuGraphics A very deep rackmount unit with a QIC tape slot in the front A very deep rackmount unit with two 8" floppy drives - model A02028-501 "030 Storage Module" The backplane looks DECish to me - similar to what I've seen in a 11/44. Here's some of the cards that are in it. Three M8017 - I know what these are :) One M8043 - I know what this is too :) Four boards #20033 - each has a tiny 4 pin connector and a tiny coax type connector (much smaller than 10b2). Main chip is N8X305N one #70201 which obviously went to external devices - two 50 pin headers which end in same connector 11/23 uses to go to external RD52's Sheild/bus terminator board - #203763 What appears to be a memory board and has a 40 pin connector on it - #75063 One board has a ton of different size ribbon cables coming off it - label says "FWD0106" Plessey Peripheral Systems board with 50-pin berg connector #703755 Small board #20041 with 14 pin berg coming off the side 2 card cpu set - #20038 and #20039, about 5 AM2901CPO chips, and a lot of N82S191N chips that say things like "instruction decoder" The SLU cards I can use in my 11/23's and 11/73's. I noticed that the back of the cpu cabinet someone had labelled the ports - some said terminal and some said "typesetter". Any idea what these cards are and if they're usable in other dec systems? I left the QIC tape drive behind and they said there was more where that rack came from - anyone interested or is this junk? Trash pickup is on wednesday so let me know before then :) Jay West

Wanted: Manual and/or switch settings for Intel iSBC-012CX memory card

by eric＠brouhaha.com

I recently was given some Intel iSBC-012CX memory cards. These are 512K ECC DRAM cards that support both Multibus and an auxilliary high speed memory bus on the P2 connector (iLBX?). There was also a version that omitted some components and didn't support the aux. bus; I think that was the iSBC-012C. There were also partially populated models with 128K and 256K capacity; I think those were designated iSBC-028C[X] and iSBC-056C[X]. Anyhow, I'm looking for a manual for these boards, or at least information on jumper settings. Multibus originally only supported a 1M address space, so two of these would fill it up. Later A20-A23 address lines were added, but they were put on the P2 connector. Thanks! Eric

I don't remember seeing 8-in-a-row in the Commercial Mate-N-Lok range for a long time, but two-rows-of-4 still exists, as does most of the rest of the range.

Some Sun and SGI cables use five or six. For example, an SGI keyboard cable for an Indigo uses pins 1-5, and early 4D series use all six.

Big Score at Dayton Hamvention RCA VIP 3301 terminal

by ethan_dicks＠yahoo.com

I only got to spend Friday morning at the Hamvention, but I think my biggest find was an RCA VIP-3301 terminal. I remember seeing ads for this 20+ years ago. The seller started off asking $50, but I talked him down to $10. eBay eat your heart out! Inside, the 1800-series chips are the following - 1802, 1854, 1869, 1870, several 1852 I/O ports, a couple of 1856 latches?, one 1867, and one 1823. The RAM appears to be five 2114 chips, the rest is glue logic and some level converter hardware, including optoisolators for the switch-selectable 20mA mode. The configuration jumpers read as the following: UC U & LC E/O M/S E/M O/S 2SB 1SB F-DPX H-DPX CTRL OFF 40/24 20/12 CL EIA LOCAL LINE 110 300 1200 4800 9600 19.2K And the backplate has the following - volume pot, speaker on/off switch, RCA video-out jack, unmarked 5-pin DIN, DB25F serial connector, 5-pin DIN marked "POWER" and a power switch. There is a LM340T bolted to the case inside, so presumably, it takes in something around 7-9VDC and regulates it down to +5VDC, but since the design is 100% CMOS and Linear circuits, it doesn't _have_ to be exactly that. So... beyond the obvious things I've mentioned, does anyone have any interesting comments about this beastie? At this point, I have no idea if the membrane keyboard is any good. I have yet to power it on.

Great Find

by jrkeys＠concentric.net

Went to a police auction on Saturday and picked up a HP95LX that works great for only $5 in a box with 3 other items. No power supply was with it that I could find but it works fine using two AA's. Stopped at a Goodwill on the way home and got a couple nice mouse pads for the collection and couple nice books.A couple weeks back my wife picked a brand in the box 512k memory card for the 95LX and the cable connection kit for the 95LX at the same store for about $5 each Will be going down to Houston for two weeks and hope to get some good finds while there.

Mate-n-lock connectors?

by wilson＠dbit.dbit.com

Does anyone know of a source for new Mate-n-lock connectors, the horrible 8-pin nylon things that DEC used to use for everything? I'm specifically looking for the female ones with PCB-mount pins. The prints I have in front of me (for the G848 flip chip) say the housing is 1209340 and the pins are 1209456, but those part #s aren't listed in the CAS pricelist (even if you add 00 on the end and put hyphens in the appropriate places). Amp still uses the name "Mate-n-lock" for some of their current nasty nylon connectors, but I couldn't find anything on their web site that had 0.200" spacing and 8 pins in a row, and none of the regular electronics catalogs seems to have anything that looks even remotely right. Inmac used to sell the bare connectors in the early 80s, but they got eaten a while back and as far as I can tell there's no trace of their mini-oriented stuff left. Thanks, John Wilson D Bit

Semi-OT: DECstation/TZ30 question

by healyzh＠aracnet.com

Since this is related to getting 2.11BSD up on my PDP-11/73 I figure it's Semi-OT. OK, I figured since I'd had to pull the TZ30 I might as well just plug it into the DECstation 5000/133 I've got. I take it that such a beasty won't recognize a TZ30? Doing a "CNFG 3" turned up the two RZ25's in the thing, but not the tapedrive, and I couldn't see it from Ultrix 4.3 either. Once again I'm asking myself *why* am I doing this, I like my UNIX lightening fast and flashy. Zane | Zane H.

PDP-8/L teletype connection

I have used a PC (ok it was an old TI PC, used a different serial port which supported hardware flow control which I connected to the reader run signal) to talk to my 8/I, I built an external current loop converter. If you need more information on this email me, from later postings it looks like you might have a current loop card for the PC. If you get overrun problems it may be due to not having the reader run signal. The 8/I serial port is not double buffered so it doesn't have much time (1-2 bit time) to remove the character before it is lost by the next. If I remember correctly only some things like Focal couldn't keep up at 110. David Gesswein

Available: a couple of bare TU58 drives

by pat＠transarc.ibm.com

I have two TU58 bare drives, also picked up from eBay about a year or so ago. I've decided that I'm unlikely to ever use them, and would like to see them go to a good home. I've never tried them and can't guarantee they work, though I was told that they were functional when I got them. I'll be happy to give them away (but please reimburse me for shipping if possible) to the first person who sends me a note to ask for them, and who has an actual use for them (i.e., is actually maintaining a VAX-11/750, a PDP-11/44, or some other system that uses these drives). Please respond to me only - no need to clutter up the list (replies sent to, or cc'ed to, the ClassicCmp mailing list will be *ignored*) --Pat.

Farallon "Project Emily" ?

by pat＠transarc.ibm.com

In tidying up a bit this weekend, I've unearthed one of my eBay purchases >from about a year or so ago. Apparently a couple of Farallon prototypes, marked "Farallon - Project Emily"; they're brown, sheet-metal cases, with two RJ45's marked "ETHERWAVE" (and one sub-marked "ETHERNET", along side an Ethernet AUI connector), an RJ45 connector marked "ISDN U", a mini-DIN connector marked "CONFIG CONSOLE", and another RJ45 marked "PHONENET LOCALTALK". I really don't know what these are, and neither did the guy I got them >from - I just bought them on a lark. I can only guess that they are some type of Ethertalk/Localtalk-to-ISDN router/bridge. Does anyone know what, if any, product these might have been prototypes for? --Pat.

Argh! TZ30 Question

by healyzh＠aracnet.com

Well, after spending the last several hours transfering the files for a 2.11BSD Boot tape over to my RSX-11M system I proceeded to try and write them to tape. Not sure if I was doing it right because the TZ30 proceeded to eat the TK50! Does anyone have any suggestions on how to get a TZ30 to rewind a tape and spit it out? It looks to have wound the entire tape around the spindle. It acts like it tries to rewind the tape, but then it just sits there with the three lights flashing. Now someone mind reminding me *why* I'm even trying to load 2.11BSD on my /73! Zane | Zane H.

rescued a beehive!

by rigdonj＠intellistar.net

Yesterday I picked up one of my more unusual finds, a Beehive MicroB terminal that looks like it's new in the box. See pictures at "http://www.intellistar.net/~rigdonj/beehive/b4.jpg" through "http://www.intellistar.net/~rigdonj/beehive/b9.jpg". You can see in picture b7 that it was still sealed up in a plastic bag inside the box. Does anyone want this? I don't need it and I don't have room to keep it. I powered it up today and it appears to work. You can see in the last picture that it does have a raster and cursor. I don't have a systemn that uses a terminal so I can't test it beyond that. The screen is normal but the camera frooze the raster in mid sweep so it appears that only half the screen has a display. Again, the screen is ok and it does have a full screen display. Youcan see the cursor in the top LH corner above the highlighted portion of the screen. If anyone is interested in it, contact me directly. It's located in central Florida. The buyer pays shipping and a modest amount for my time. Joe

more weird stuff - ChameLAN 100-s

by rigdonj＠intellistar.net

Here's something else that I picked up in a load of old computers last week. It's one of those oversize lunch box computers with the keyboard that folds up against one side and covers the screen. It has six ISA type card slots that lay horizontal in the main unit. There's also a piggy back unit that has three more ISA type slots that stand vertical. The logo on the keyboard says "Tekelec" and ChameLAN 100-S". After some work, I finally got it to boot. The first surprise was that the LCD screen is a backlit color screen. The next surprise is that it boots into some kind of UNIX. I never did see a name for the UNIX but it pops up a number of different copyright notices including one for DOLCH, Tekelec and the usual UNIX ones. I couldn't get past the login id/password prompt. Any suggestions about how to get around it? It has some strange cards in it including several that appear to be very fancy Ethernet cards and another that has four fiber-optic connectors. The three boards in the piggy back unit are physicaly bolted together and each one has a four pin power connector similar to a 5 1/4" disk drive. There is a cable that connects to a each of those power connectors and a power outlet on the motherboard. The external connectors on these boards are marked "Bypass Control", "TR1" and "TR2" and "AUX". One of the boards has a big IC that's marked AMD AM79C830GC on it. I haven't been able to find a refernece to this chip. One of the other boards has an AMD AM7984AJC/20 on it. I haven't found a reference to that one either. Does anyone know what they are? The main computer is a 32 Mhz 486 with 16 Mb of RAM. The hard drive is a type 11 245 Mb IDE drive and it has a 1/3 height 1.44 Mb floppy drive. There are also extra LED indicators on the front of the computer that are marked "Ring Op" "Pri" "Sec", Signal Detect" "A" "B" and "Active" "A" "B". Does anyone know what this machine is made for or anything else about it? Joe

PDP 8/L console

by djg＠drs-esg.com

>From: Lawrence LeMay <lemay(a)cs.umn.edu> >My PDP 8/L that I recently acquired, has a cable that i assume is for >the console terminal. It has a 9 pin male connector with only pins >1 through 6 present. Is this a standard serial connection? This was >a papertape based system, so it may have been connected to a teletype >ASR 33.

You can either create an external RS-232 to current loop or make a new W076 to do RS-232. If you want to cheat you can reduce the capacitor on the M452 to increase the baud rate. The serial port is not double buffered so you may have problems with overruns when sending tape images to the 8/L. I think the BIN/RIM loader is fast enough but Focal is not. On the teletype the data was held off by the reader run signal. >Also, I'm very curious about the other cables comming from the 8/L... >I have 6 flat black cables, similar to ribbon cable but thicker, with >9 'wires' on each cable. possibly each 'wire' is something similar >to coax, but i'm not sure...

This extends the 6xxx instructions to external equipment and allows the external equipment to do 1 and 3 cycle databreaks (DMA). With 6 cables only programmed IO is supported, 10 or 11 are required for databreak. The labels are the location they plugged into the the peripheral. I think most DEC stuff like the DF32's I have on my 8/I use Flip chip connectors on both side so it may of been a third party peripheral. David Gesswein

heads up MMJ crimper tool.

by cmcmanis＠mcmanis.com

As the saying goes, "If you don't live here you probably don't want to go there." Basically Fry's sucks dead rodents through a hose. And most of the stuff on the shelf seems to have been returned at one point and never do they shave a penny off that price. I once heard someone brag that they didn't need to buy a digital camera, they just bought one at Fry's and returned it when they were done. :-( That and the fact that they drove the decent electronics stores out of business makes me hate them even more. However, they do get things now and again and if you know _exactly_ what you want, they can be useful to have near by. Other places stock the Ideal Industries tools, however the MMJ one is often not stocked. If you need one, I could probably be bribed with a couple of dozen uncrimped MMJs to be your transfer agent and get you one. Contact me off list if you want to go that route. --Chuck At 03:58 PM 5/19/00 -0600, you wrote: >Well, I know where there's at least one full box of MMJ's but no crimp >tool.

Wacky terminals

by xds_sigma7＠hotmail.com

Well, FWIW, I do have the schematics + owner's manual + maintenance manual for a Hazeltine 2000... as for actual terminals, I've got a Prime terminal, an IBM 8775, and my long-time favorite, my trio of Perkin-Elmer 550B's. I had an ADM-11, but the stupid hunk of junk was dead when I got it, so it was pretty useless... I could use 3 more P-E 550B's, and a trio of Carousel 300's, but I doubt anyone has any... Wouldn't mind a CR-11 (I KNOW that its not a terminal, but since I'm on the topic of Interdata/P-E stuff I want...), so I could change the ROMs and use it on a 7/32... have the controller, but not the card reader... ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

RSX-11M/M+ Question

by healyzh＠aracnet.com

Is there a way to configure either RSX-11M or RSX-11M+ to boot up off of a disk that it can't write to? I just created a backup CD-R of my RSX-11M system, but since it could't write to the disk as it was coming up it didn't come up in a usable state. However, it did boot. Alternatively would it be possible to boot standalone backup off this CD or build a CD with standalone backup? RT-11 is a little more forgiving :^) Though I messed up and didn't have the partitions assigned correctly before making the disk image so I can only access part of my data when booting from CD, still it's enough to be able to recover the system with should I loose the HD!

I think the driver of smaller size is the desire for lighter weight, without sacrificing features, since so many people use only their laptops now, rather than having a desktop as well. Anyone who's had to carry a 20+ lb laptop bag in addition to a briefcase, suitcase, etc. can appreciate why smaller size and lighter weight is a Good Thing (tm). Try lugging a Mac Portable with a spare battery around for a day and you'll see what I mean. Regards, Mark.

OT Rant: Smaller/thinner laptops.

by netsurfer_x1＠hotmail.com

I'd like to share a revelation I have had about modern laptops. I have noticed that nearly every new laptop generation on the market is roughly about a third smaller than the previous generation. But does anybody know why they make them this way? One might say that this is so because of new manufacturing processes, new technologies, etc. But in my opinion, I think laptops are made as thin as they are so you can be lost or stolen easier. If you lose a new laptop, you are probably out $1500 or more! That's why I like older laptops like a Tandy Model 100, Macintosh Portable, etc. because of these reasons: 1. Large size 2. *Proper* keyboards (laptop makers, please thake note!) 3. Phenominal battery lives (see above comment) 4. If they are lost (nobody would really want to steal an obsolete laptop) you are out maybe $50-150 or so. So the newest technology is better, I beg to differ! ____________________________________________________________ David Vohs, Digital Archaeologist & Computer Historian.

WTD: HP9000/735 Ethernet Board

by dlinder＠uiuc.edu

Hello List, A friend of mine has recently acquired an HP9000/735, and he's looking to get an ethernet adapter for it. (it either didn't have one, or the one he had was less than functional). It is HP PN A2095-66584, the AUI ethernet board for an HP 735. He would also be interested in the thin lan card instead, if someone has one of those available for sale. thanks a lot in advance. - Dan Linder / dlinder(a)uiuc.edu / upside(a)mcs.net - - Riot sounds start riots. / keep talking... -

(Actually this was done with some sort of front-end that had been in part developed at the University of Maryland, hence had the name SMUCS but doggone if I can remember what that stood for.) So it didn't try to be more than a glass Teletype, and nobody thought to use it as anything more than one -- mostly this arrangment got used to edit files using @ED (an interactive editor, but still Teletype-oriented) and submit batch jobs. -Frank McConnell
