This one is light and small enough to be shipped. It's a 'Gigastore' drive from Digi-Data Corp. Best of all, it includes the operation/maintenance manual(!). The 'Gigastore' is a weird device. What Digi-Data did is take a regular VHS VCR, make some modifications to the transport assembly, and added their own electronics to provide a Pertec interface. The result was a tape backup system that used regular VHS tapes, could store up to 2.5 gigabytes of data, and could interface to any Pertec controller. This one's cheap: $25.00 or best offer, plus shipping. Also, FYI: The HP 9-track drive I mentioned earlier would include the manual. Thanks much. -=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com ARS KC7GR (Formerly WD6EOS) since 12-77 -- kyrrin(a)bluefeathertech.com "I'll get a life when someone demonstrates that it would be superior to what I have now..."

HP 3000 No More

Development of Alpha started in 1968 and ran concurrently (if somewhat on a back burner, because everybody thought the 32-bit Omega was a more exciting project) w/r/t Omega until Omega's cancellation in 1970. November 1972 is when the first systems (called HP 3000) were shipped to customers. The re-release (which was somewhat improved hardware and software and also called HP 3000 initially, but later came to be called the Series I) was in October 1973. (Reference for the above: Christopher Edler's "The Strongest Castle" paper) > The 16-bit HP 3000 was never multi-CPU.

The multiple-CPU > support came with the PA-RISC system, with release MPE XL 3.0 Somebody had ideas about it being a dual-CPU shared-memory system early on. Looking at the HP3000 Computer System Reference Manual from September 1973, I see that locations %10-%13 were reserved for the second processor's current PCB pointer, QI, ZI, and interrupt count. The Series II added two instructions: LOCK and UNLK, which were used to provide a sort of in-memory semaphore. I'm not sure they were present in the Series III. The Machine Instruction Set manuals I have handy have them footnoted with "Series II computer systems only". What I don't know is whether MPE ever had dual-CPU support. If it didn't, I wonder how they worked out that having an in-memory semaphore would be a good idea. -Frank McConnell

HP 3000 No More (legacy)

[knee-jerk reaction to a pet peeve follows] Well, as long as "dead" can be defined as "salespeople don't want to sell you a new one". For me, it can't. I can pick up the phone and buy PDP8 equipment from a commercial vendor. How long ago was THAT architecture discontinued? For me, something is "dead" (or "obsolete" or whatever you want to call it) when it can no longer do its job adequately and cost-effectively. When Ford or Chevrolet discontinue a model of a car, does every owner of that model of car go throw them away and buy brand new cars? This industry is absurd, and its practices and philosophies are repulsive at best.

Now, Stan...I apologize if it seems as if I'm jumping down your throat with this, and believe me I do get the impression that I'm precahing to the choir.

AVAILABLE: 9-track SCSI-SE tri-density tape drives

by kyrrin＠bluefeathertech.com

(Cross-posted to: classiccmp, and the port-sparc and port-vax lists at NetBSD.org) NOTE: LOCAL PICKUP ONLY EXCEPT BY SPECIAL ARRANGEMENT: I'm sorry, but these are too big and bulky for me to easily ship unless you want to pay $150 for a special box plus the freight charges. Pickup location is Kent, Washington (southeast of Seattle). -=-=-=-=-=-=-=-=-=- Hi, folks, Due to shifting interests, and a massive cleanup, I'm getting rid of two 9-track SCSI interface tape drives. Both are multi-density, both are standard single-ended SCSI interface, no oddball connectors, and I'd like to ask for $100 OR BEST OFFER on each one. Here's the specific details. HP 88780: Handles 800, 1600, and 6250 density tapes. Front-loading/autoloading, rackmount, and in pretty darn good shape. Originally badged as a Sun drive, and I seem to recall that it ID's as a Sun device. However, it worked just fine with standard SCSI hardware. Includes rack slides, functional when last turned on a few months back. M4 Data Model 9914R (rackmount). Handles all four known densities: 800, 1600, 3200, and 6250. Also front-load/autoload, also in great shape. I can probably come up with a set of rack slides for it as well. Somewhat lighter than the HP in physical terms, and it can be easily converted to a Pertec interface by removing the SCSI interface board and changing one parameter in the NVRAM setup. Thanks much for putting up with my blatant ad. ;-) -=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com ARS KC7GR (Formerly WD6EOS) since 12-77 -- kyrrin(a)bluefeathertech.com "I'll get a life when someone demonstrates that it would be superior to what I have now..."

OT: paging MAC expert(s) --- What's a Performa?

by mythtech＠Mac.com

>The documentation that came with this machine implies it's already >equipped with >the DX2/66. Is there some sort of utility in the system that would make >it easy >to see what the thing perceives itself as having? If you boot it, you will probably find a copy of Apple System Profiler in the Apple menu. That will tell you what you have installed. The stock 630 series is actually a fairly useful machine. It used 72pin SIMMS (FPM, but EDO work just fine), there is only one RAM slot, so it will max out the machine at 36mb (32mb chip + 4 on board). The VRAM is non upgradable. As a stock machine, they are good workstations (pending you use non PPC only software, since it is a 33mhz LC040.. the LC040 is a 68040 without the FPU built into the chip). I have a 630 running right now as a mail server, keeps up with everything I give it no problems (runs Mac OS 8.1, with Stalker Internet Mail Server... hosts a few domains and a few thousand emails a day, with a few hundred accounts... never even hiccups). The HD is IDE, which makes it cheap and easy to upgrade. Other things of interest. It may have an ethernet card, but if you said it came with a modem, I doubt it has ethernet (was the modem internal? You could get an internal 14.4 geoport fax/modem in the Comm Slot... the GeoPort modem is similar to those WinModems that use the processor to handle all the modem functions, and the modem acts pretty much as an AD/DA converter. HOWEVER, you may have one of the modems that was made by global village... THOSE modems are real modems, and VERY VERY good, with supurb fax software). If the modem is external, then you might have an ethernet card in the Comm slot (look at the back for an RJ45 connector). If you have a Global Village external modem (common performa modem), the bronze (probably the one you have) is 2400 fax. It is a VERY good fax modem, with excellent software... not so good of a regular modem (some extension conflicts with the modem control software). There is also a Gold version that was 28.8 fax... much better regular modem (newer software, cured most of the extension conflicts) Also, your docs indicate that it has the DOS card installed. However, the 630 didn't ship with a dos card... that was the 640 (upgraded version of the 630, the 640 came stock with a DOS card... IIRC it was available for the 630 as a 3rd party add in by Reply, so it may have been added). The quickest way to tell if a dos card is installed is look at the back of the machine. You will see an expansion slot. If there is a fairly densely pinned DB connector in the expansion slot, you have a DOS card. There should be a dongle cable for it that will connect between the DOS card, and the Mac's video out. The cable will then provide a RGB connector, and a Midi/Joystick connector. If you don't have that cable, the DOS card is useless... good luck finding a replacement cable. Finally, the 630 supports Video In/Out and a TV Tuner. Again, look at the back of the machine, if you see RCA connectors for video, left and right audio (Yellow, Red and White, RCAs), you have the video In/Out card. If you ALSO see a RF Coax screw on connector, you have the TV Tuner... if you have these... contact me, I would be interested in possibly buying/trading them with you (I have a need for the TV Tuner card, but will take them as a pair). If you have the TV Tuner card, you should also have a remote control. It will either be a skinny black remote, or a little credit card sized remote. Failure to have the remote will not prevent the card from working, it just means you have to do all the controls on the computer. (The Video Player software supports all the remote functions directly, the remote was just a nicity). What else... If the DOS card is not present, then the 630 has an LC PDS slot, there are a few cards available for it (network, video, accelerators, odds and ends). I think that is pretty much it. The 630 series is a very good 040 machine, and can still be used for a number of things. -chris <http://www.mythtech.net>

Control Data Cyber 960 rescue interest?

by mhstein＠usa.net

Speaking of CDC, among the junk I'm cleaning out of my basement there's a partial backplane out of an old CDC something-or-other, connected to a panel with 2 AC outlets (Monitor & Data Set), a fuse and a DB25 for the Data Set. There's also an acoustic delay line and a large resistor/diode matrix board which I think came from the same piece. Maybe a 60's era terminal??? 3 rows of cards; the two top rows A & B have 25 slots for 4 1/2x6", double sided 31 edge connectors cards, some with 10 test points along the edge and each populated with one or two dozen gold 10 pin TO5 cans marked M (as in Motorola) 115, 116, 117, 118 with what I assume are date codes like 6624, 6644, and 6636. The bottom row, C, 32 slots, contains a few smaller cards with pin connectors that appear to be some kind of programming cards, just containing jumper wires. Anybody recognize these and maybe even have a use for a card or two, or can I throw them out without feeling guilty? mike

Hi again. :) I just thought of another question. I have in my possession four TRS-80 model IVs. Two portables, (one working, one not), and two desktops (one working, one not). The desktop will run in Model III emulation mode. The portable will turn on and ask for a disk. Anybody know where I can find some operating system(s) for them? I'm also thinking about taking the ram from the non-working machines, and using it to max out the memory in the working ones. Good idea, bad idea?

I doubt it is 11S as there it is uncommon. When it comes to the older core memory UNIBUS systems - good luck. I lost a couple in the fire and the hobby market has gone crazy for them over the last couple years.

And although I haven't used the 7 or 12" PC cards apple sold for other PCI PowerMacs, I have seen them, and they all use the dongle cable too.

Hello, and please help with RSX-11M/PDP parts

That would be my first thought, except that I have nothing that will boot any PDP except for that disk. :) Of course, if anyone can supply media for RSX-11, RT-11, RSTS/E or something else, that would be an option. It is my understanding that RSX (except possibly RSX-11S) uses FILES-11/ODS1, to which I have recently acquired the specification. > If that is OK, I can tell you exactly what to do if you tell > me exactly > what bits you want to change - which block on which hard > drive and to what. > The latter will require someone who knows RSX-11.

Hello, and please help with RSX-11M/PDP parts

by csmith＠amdocs.com

This will be a lot to cram into one mail, but here we go... First off, Hi everybody. I'm newly subscribed to this list. Next, I was wondering whether anyone here can help my with my newly acquired (IE rescued from the crusher) PDP-11/73. Straight to the point, I can get it to boot up RSX-11M, which is installed on the fixed drive, and do *stuff*. (please correct me if I'm wrong on any of this, by the way) I've figured out that the previous owner has disabled logins from the console port, perhaps to defeat the "forgotten password" procedure that I can't get to work ;) I can hit ^C and get an "MCR>" prompt, but nothing else. There is another port which has user [10,10] logged in automatically when the machine finishes booting, so I've been able to experiment with it some. I've managed to figure out that INS and REM are MCR commands to insert and remove images from the system. RUN seems to automatically insert, execute, and perhaps afterwards remove an image. HEL will log you in (but not without a password!), and BYE will log you out. What I'm missing here are basically any file-management commands! :) Does anyone have a short reference? I could also use suggestions on a recovery procedure to get access to the 0,0 account. Here are my thoughts: Put the drive in a MicroVAX-II (write-protected!), in place of the MicroVAX's system disk. MOPboot the VAX from another, larger VAX, and <edit?/move/do-something-to> either the UAF or the startup files to change the 0,0 password, or change the boot procedure so that the "forgotten password" process will work. (Anyone know if this is possible, or whether there's an easier way?) My understanding of this "forgotten password" process is that you hit ^C early in the boot procedure to get the "MCR>" prompt, and run the command REM ...AT. to de-install the command-file processor so that the system can't fully bring itself up. This somehow should cause the system to give you privileged CLI access. This system is a MicroPDP-11/73, with an "MFM" type fixed drive of unknown size, two 4-port serial boards, and an RX50 (I think that's the strange 2-in-1 floppy drive?). It tells me on bootup that it's got 512k of RAM "mapped." I've been assuming that this is the full amount of built-in RAM. Please correct me if I'm wrong there. I'll get the CPU revision/OS version/etc if needed, but I don't have the system handy right now. Once I get the machine up and running, I'll need to make a good backup of the drive, in some kind of bootable form, since it's the only copy of RSX I've got. I hear there's a stand-alone BRU. Is that the way to go? It's likely I'll backup to floppy, and image the floppies to CD. I may also remove a tk50 and controller from a MicroVAX II, so that I can backup to tape, and dump the tape into a file using one of my VAXen. Given all of the above, any suggestions? If I've kept your attention this far, let me also ask another, more open-ended question. I'd like to get an older, unibus based PDP-11 eventually. Ideally, here is what I'd like: Core memory Programming switches on the front-panel Reel-to-reel tape Small package (meaning half-size to 2/3 size a normal rack. I've seen pictures of things like this. Some kind of disk storage Multi-port serial Any advice on collecting parts, or finding old parts/systems? I've already been given, and taken the ebay advice. No luck there yet. Regards, Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

Datapro Reports on MiniComputers ???

Any one familiar with a wonderful series of loose leaf binders from DataPro ... "Reports on Minicomputers" circa 1978-80 or so? I just saw a set and would love to find a set for sale! More info than I've ever dreamed of ... all in one place .. and covering just about everything you ever wanted to know about many mini systems. ie: they had a really full writeup on InterData systems w/info I had never been able to find [maybe 30 pages of stuff .. all stamped "Not to be Reproduced"] anyone know if they are still in bix and would object to reproduction?

In need of external SCSI enclosure...

by john_boffemmyer_iv＠boff-net.dhs.org

Anyone out there have a HD50, 4 bay external SCSI enclosure they are willing to part with (trade/money/etc.)? I've noticed that I've accumulated a small pile of old IDC50 1gig SCSI drives and I have decided to actually use them instead of allow them to keep my computer room door propped open. I've verified that they work, etc, but my little case cannot fit more than 2 drives (yes, a sucky mid-tower) and logically, an external would suit my needs. Finding them on ebay is like looking to pay porshe prices for a yugo. I last saw one (actually a 2 bay HD50) go for about $130 US, USED without power supply! Is there anyone out there willing to help spare my sanity for my SCSI obscession? Maybe it will give me room to play with my 2X SCSI CD-ROM drive and 250Meg Tape Drive... -John Boff. ---------------------------------------- Founder, Lead Writer, Tech Analyst and Web Designer Boff-Net Technologies http://boff-net.dhs.org/index.html ---------------------------------------

Cromemco + DIAB

by mhstein＠usa.net

-----------Original Message---------- Date: 15 Nov 2001 8:57:4 +0100 From: "Iggy Drougge" <optimus(a)canit.se> Subject: Cromemco + DIAB There's been some talk about Cromemco recently, and in one single Usenet post, I read something about a Cromemco UNIX box actually being a DIAB design. Presumably, this would be a 680[23]0 design. Do you have any ideas? ------------------------------------- Don't know if DIAB had anything to do with the design, but FWIW, Cromemco's Unix systems were S-100 based, first using a 10 MHz 68010 (XPU card), and later a 16.7 MHz 68020 with a 12.5 or 25 MHz 68881 (XXU card); don't know if anything came after that, maybe Cromemco in Europe might have more info. mike

MV3100 Memory

by geoffrob＠stmarks.pp.catholic.edu.au

An acquaintance (freeware developer of VMS web/proxy server package) is looking to source some memory for a Microvax 3100 that some organisation in Macedonia (not sure which Macedonia, but probably the FYR) wish to use for a Web server. (seriously!) Anyone have anything in that line they would be prepared to part with cheap? I've offered a complete (minus drives) MV3400 and/or a 6000 but the freight would be nasty even on the 3400, so they really just want some ram. Sources in Oz or Europe preferred, but if the price is right, wherever.... OTOH, if someone in Europe has a complete VMS/Vax system that might be suitable and can arrange it to get there, that would be good too.

Xebec Sider for Apple II

by r_beaudry＠hotmail.com

Hello all, I recently received a Xebec Sider drive (external hard drive for the Apple II) -- Thanks RE! It did not, however, come with the card that goes in the Apple II, nor did it come with the cable. Judging by their going price on eBay, I know this is a futile attempt, but does anybody have a spare card/cable that they'd be willing to part with (or could be pried out of their hands by $)? I'd rather not pay eBay prices, so perhaps a trade?? Anyway, let me know, and try not to laugh too hard.... Thanks! Rich B.

Yeah, but how wide is "wide"? The card I have seems not to be what's required. It's intended to connect to a Xebec card all right, but the connector is only 26-way. Thanks to Dick Erlacher who mailed me with the details, I know the Sider needs rather more wires (all 50, probably). My card was made by HAL Computers Ltd in 1983, labelled "APPLE 2/3 XEBEC INTERFACE REV 1", and the only strings I can find in the EPROM are "(C) HAL COMPUTERS LTD 1983 A/XHAL SHARED RESOURCE WINCHESTER SYSTEM", "NOT CONNECTED", and "SRS ERROR". If anybody knows any more about this, I'd be interested to hear about it, otherwise it will languish in my box of odd cards for a day when I'm particularly bored and decide to try it out (yes, I have a spare Xebec controller and ST412 drives). -- Pete Peter Turnbull Network Manager University of York

food

Skip to the the end part of this message to learn what typical American meals truly consisted of in the pre-vegetarian times. Hint: ...it wasn't fast food or hamburgers. :-) On Fri, 9 Nov 2001, Chad Fernandez wrote: > You forgor the 80's..... hamburger chains WITH salad bars! Wendys was > the longest running, well into the 90s, but Burger King had one for a > short while too, maybe even McDonalds too... I don't recall. The first fast-food chain that I recall having a salad bar, and that was back around the late 1970's, was White Coffee Pot Jr... not sure if they were just a Baltimore area phenomena or if they existed elsewhere. They were not the typical fast food chain, as, in addition to the salad bar, one could get fried shrimp, carrot cake, crab soup, and towards the end, cheese steak subs. The french fries were delicious as they were cooked in chicken fat (that was back in my pre-semi-vegetarian days); trying to remember if they sold fried chicken as well - I think they did, but can't swear to it. Next, Gino's hamburger chain had a salad bar - that was back in the late 1970's as well. It was an "all you can eat" salad bar, and, if one purchased a hamburger, one could use any toppings one wanted from the salad bar on it - the styrofoam packaging used back then made it very convenient to fit lots of salad toppings in with a hamburger to go. > Mike Ford wrote: > > > Different foods have there times, around the 60s it was "chili bowl" > > joints, 70s salad bars, 80s hamburger chains (that failed to go away). > > Whats an orthodox diner meal, lettuce salad, meat and potatoes with gravy, > > some kind of veggie, and a slice of pie. How about a guess on the top ten > > favorite foods in USA (by meals eaten)? Ok, to help the rest of the world understand the truth about American food, here's what typical American meals really consisted of in the pre-vegeterian times: When I was growing up, we always had a wide variety of vegetables - and they were fresh, not frozen/canned, when in season (corn, peas, string beans, lima beans, peas, sweet potatoes, broccoli, brussel sprouts, lettuce, tomatoes, etc...) with meals; potatoes were often mashed and served with gravy - sometimes they were baked and topped with salt, pepper and butter or margarine. Meats consisted of roasts, steaks, pork chops, ham, chicken, lean ground beef, shrimp, and occasional Cornish game hens. In the summer we also had fried chicken, crab cakes, hamburgers outside on the grill, fried tomatoes, corn on the cob, fried eggplant, fresh salads (definitely not limited to lettuce, by the way), watermellon, etc. There was always fresh fruit to go along with lunches, such as apples, peackes, nectarines, pears, oranges, etc. ...then meals with a turkey to be sliced on Thanksgiving and Christmas. ...and for breakfast, one or more of: cereal with milk, toast, scrambled eggs, waffles, french toast, grapefruit, bacon or Taylor's pork roll, and orange juice to drink. -- Copyright (C) 2001 R.

I scrap/dispose of/remarket gear for a living, so I've dealt with a lot of scrap, though nothing really mainframe related. Gold processors like Pentium 60's have around $50 a pound worth of gold in them, never pentiums maybe only $35 to $40(that's what's in them, the scrapyards will pay around half that) The presence of other things like platinum, palladium, rhodium or other more exotic metals can complicate these calculations, and old processors most likely have more precious metals content than the old pentiums. If they use anything like the TCM modules in IBM mainframes (the HUGE PGA package chips maybe 4 inches on a side, and use them in any quantity, there may be some real scrap value, since those things have around $75 worth of metals apiece in them by current prices. Standard PC motherboards go for around 65 cents a pound, daughtercards go for almost $1/lb, card edges $25/lb. Aluminum drives go for around 10 cents/lb or so, more like 15 when the Al market is decent. The racks are pretty much worthless if they're steel. I've heard figures as high as $3/lb on old Q-bus boards, though I'm not sure if the place was buying them for scrap or resale as Q-bus boards. If anybody can get me any further information I'll do my best to come up with a figure. -Chris

Cromemco + DIAB

by optimus＠canit.se

There's been some talk about Cromemco recently, and in one single Usenet post, I read something about a Cromemco UNIX box actually being a DIAB design. Presumably, this would be a 680[23]0 design. Do you have any ideas? -- En ligne avec Thor 2.6a. SCSI is *NOT* magic.

New acquisitions: Suns, room

by jss＠subatomix.com

I just acquired my first two Sun workstations. One is a 3/50, which came >from a list member (thanks, and don't feel so bad about destroying my cell phone :-) :-) ), and the other is a 3/60, which came from elsewhere. A few monitors, keyboards, and drives made it in there somewhere, also. I still have a Sparcserver 490 in my, um, "storage facility" (read: parents' garage) that was a stowaway from a trip earlier this year. The Sun collection has started. Another list member graciously donated two RX01 units, which will eventually make their way into some sort of PDP-11. So far, I'm met 4 list members IRL. I hope to see more of you soon. The biggest news is that I'm getting some more room. A LOT more room. Of course, another way of looking at it is that my wife has decided she's a lesbian, wants a divorce, and is moving in with her new girlfriend. Either way you see it, I'm going to be making some changes around my house. First, all of the traditional living space and sleeping space will be compressed into one room. The bathroom, kitchen, and utility room will retain their functions. The rest of the house will become my retrocomputing playpen. The detached garage, now devoid of her car, will make a great storage area for stuff I'm not actively playing with. I don't have a large house, but all in all, I estimate I'm getting about 500 to 750 additional square feet to do stuff in. -- Jeffrey S. Sharp jss(a)subatomix.com

In need of external SCSI enclosure...

Is there anyone out there willing to help spare my >sanity for my SCSI obscession? Maybe it will give me room to play with my >2X SCSI CD-ROM drive and 250Meg Tape Drive... I "built" one of these a while back. I bought a cable from MCM Electronics (Cent on each end, and 4 IDC in the middle). I think the cable was about $40. I then stuck my drives (a CD burner and an HD, with 2 spaces to spare), into a spare PC computer case (I paid $20 on the case with a 250 watt PS included). The case gave me access to 4 5.25 1/2 height bays, and 2 3.5 bays (all bays are external, no additional internal, however, since there was no logic board, I could mount things on their side using that space if I had wanted to). For heat venting, I placed an extra case fan (I used one of those slot mount ones since I had it on hand). I also scrounged up some old slot plates that fit the centronics connectors on the back (don't remember where I got them, but I had them from something... I think you can buy them for a buck or two). It worked very well for about a year, then I needed the case for a PC, and I had upgraded my internal HD so I no longer needed the extra SCSI drive. Now the CD burner sits on top of an old external Jasmine HD case so I can use the PS and IDC to Cent cable from it (since the Jasmine drive is LONG since dead anyway). -chris <http://www.mythtech.net>

Previously we've seen Falcons, Amigas, C64s, a Vectrex, a Commodore PET, a Telmac, Spectrums, UNIX workstations etc. etc. We are also combining all of this with experimental and alternative art. Some artists who will be playing live at the 3-day event: Pnmf!, Tero M?yr?nen (plays live music with synths and a C64), Telamurska, Happo, Analogia, No I Aint. It will take place in Helsinki, Finland from the 11th of January to the 13th. For more information contact me or visit the website, http://www.altparty.org/ (check the archive for an invitro from Wildfire for the Falcon!). In addition, we've set up an area for collecting together information about cool machines and interesting art, or the "Alternative Wiki". Absolutely anybody can contribute information to it by clicking "Edit Text" at the bottom of any page, and add new pages freely. If there are people here who would like to contribute, please do!

Altair 8K BASIC configuration

by RCini＠congressfinancial.com

While trying to get the 8K BASIC to work with the Altair emulator, I've figured-out that there must be some way for the user to define, using the sense switches, which I/O ports could be used for the console. Does anyone have the manual for 8K BASIC or handwritten notes on the topic? I need to find the definition of the switches at startup because I'm losing console input on the emulator when using 8K BASIC. Thanks. ========================== Richard A.

> From what era is the Cyber 960 from? 1960's? > Is it considered a supercomputer (in it's day)? Its primary architecture dates from the early 1960s. That was the 60-bit architecture designed by Seymour Cray. But this model also implements a virtual-mode in which the CPU operates in 64-bit mode. The 960 was a machine of mid-1980s manufacture; they were being sold through the early 1990s. Tidbit: "The Cyber 960 and all its peripherals took up approximately 1,800 square feet of space and required over 20 tons of air conditioning to keep cool." -http://www.csustan.edu/oit/banner/cyber.html The Georgia machine: http://www.usg.edu/oiit/pubs/update/spring2000/article5.html GIT was still running PLATO as recently as 1990, but was considering migration to NovaNET.

blinkenlights for everybody - status update (2)

by GOOI＠oce.nl

Hi all. Things are progressing nicely. The core board is tested and works. I get the monitor prompt on the VT220 terminal connected to the RS-232 interface. That means there is also software for it. Go to the updated page http://home.hetnet.nl/~tshaj/pdpsite/homebrew/startframe.html Next steps are: 1) adjust monitor software so it runs without the RAM 5565 chip 2) build the I/O ports interface board 3) write the "low-level" in- and output routines 4) write the "stand-alone" pattern SW (the Cylon-eye on the DATA LEDs) 5) the real work: interface with Ersatz-11 (..John?) The monitor software (e11-6802.zip) already contains some SW but that has not yet ran; it just assembles without errors ... - Henk.

You might get away with ordinary ribbon cable, which usually has a characteristic impedance around 100-120 ohms, for short distances, but the A cable is really supposed to be 30 twisted pair ribbon cable (one trade name is Twist-n-Flat), characteristic impedance 100 ohms.

Eight-inch

by optimus＠canit.se

I visited a shop in "Siberia" which I hadn't visited in a long time today. they had redecorated, and in the inner-most room, they had a "50% off" shelf. They had several sealed packs of eight-inch floppies, BASF-made. Their price? Five crowns! And then fifty percent off that, that's 2,50, or 25 US cents. I got two to begin with (I only had some change, and wans't aware that the discount was referring to the 5 kr merchandise. I also got some Token Ring NICs, a TR cable and a sealed case of 5?" DD floppies at the same price. Some things I did't get: A lot of WANG things; several ISA cards with BNC and TNC connectors, printer adaptors (boxes with BNC and Centronics connectors), baluns. Original Novell NE2000 cards. Bad cards, but nice to some collectors, I suppose, and useful for programmers. Odd PhoneNet concentrators. -- En ligne avec Thor 2.6a.

Corvus Floppy Drive?

Corvus made 8" and 5.25" floppy drives for the Concept, and matching controller(s) that fit in one of the Concept's slots. The controller(s) are based on the WD1793 FDC. The 8" disk drive is a Tandon half-height 8" (848?) in a box with power supply. Nothing special except it says "Corvus Systems" on the box. The 5.25" disk drive...well, I can't remember: (a) whether it used the same controller as the 8" (b) if so, what they did to get from the 50-pin connector on the controller to the 34-pin connector on the drive Most Concept floppies that I've seen have been 8", and I've only seen one of the 5.25" drives. -Frank McConnell

yet another NeXT question

by mtapley＠swri.edu

>I've never used my OD. ... >....Since it would be useless when I get a >33mhz motherboard, why bother? Well, you *could* make it useful. Do the hack to install your old 25 MHz mainboard in one of the alternate slots. Put the new 33 MHz mainboard in the traditional slot. Connect both to your ethernetwork. Have the 25 MHz net-boot from the 33 MHz, or boot it off its own optical (but I'd have it net-boot, so you can use the optical for backups or whatever). I dunno what your power supply would think of all this, particularly if that's the same system you have the Dimension in, so I recommend some caution, but if it works it'll be pretty cool. You'd still be able to access the OD, via the 25 MHz board (which you could also set up as a print server), but all your console programs would get the benefit of the 33 MHz board. - Mark

9-Track Tapes available

by mtapley＠swri.edu

All, My division of SwRI is getting rid of a large pile (appx. 1000) 9-track tapes. They are 8 inch and 10 inch sized reels, 1600 to 6250 bpi, Scotch Black Watch 777 brand (for the most part). I'm going to collect all the ones headed for the trash, stack them in my office, and either put them in the right hands or transfer them to the dumpster a few at a time if no-one is interested. Please contact me off-line (mtapley(a)swri.edu) if you are willing to pay shipping in order to have some of these show up at your door. I'm in San Antonio, Texas, USA, zip code 78238, for purposes of calculating postage. Data on the tapes is probably NASA satellite data; it need not and will not be erased, so you can peruse it or erase the tape at your convenience. - Mark

They might not consider the 180/960 worth having, it's not a historical machine, well, yes, "last of the line" would be considered historical... at least I *think* this was the last model (in the line that trails back to the 6600).

IIRC Microsoft had the SysV standard 13 character file names in Xenix like SysIII (and IIRC v7). It was BSD which did symbolic links and IIRC 255 character file names in the 4.2 BSD Fast File System... SysV got this in SVR4 (about 1989 or so)... Research had this in Edition 10... Bill

microvax 3 info: ka650-ba is single user?

by h.wolter＠sympatico.ca

Looking to upgrade one of my Mv2's and came across an auction item with a ka650-ba with 2 16 meg mem cards. The price is right - but it goes on to explain that the -ba is a single user cpu - which seems silly to me. Is there some special thing about this cpu that will only let it run single license VMs or Ultrix? I can't see how they limit that. Is the this bullsh*t? I can't find any google refs that will support the single user claim.. regards, Heinz

ISTR that they were a PLATO site, but I've no idea whether this system was running it or not. Yes, it should run, given the proper peripheral equipment (again ISTR PLATO had unique site hardware requirements). Bear in mind that PLATO is a commercial product still marketed as NovaNET (I believe it's getting yet another name at this moment), so you'd be hard pressed to get legal permission to run it. I suppose you've seen my gallery of PLATO (NovaNET) screen shots; I need to get them moved to the site Jay West said he'd make available so I can add the second gallery. -dq

I'm not gonna get in a snow-marking match on hours spent under the hood... however you are correct in that it's not a very orthogonal processor, and non-orthanogoanl machines are indeed full of "gotcha"s. Having started with orthogonal machines like the CDC-6600 and IBM 370/158, I found even the 8-bit 8080 a pain to work with, and wrote macros to do all the really important work. I carried that forward to my 8086/8 days, and thus didn't have much in the way of difficulty. I had arithmetic macros for 8, 16, and 32-bit operations, and macros to do conversions between them. I worked briefly with the 6800, and more recently, the 6802, and they are certainly a bit more orthogonal, but still too primitive for my tastes. A Coco running OS/9 might be in my future but I wouldn't spend anything for one, it'd have to be free. As to the distinction, I bow to Allison's better wording. Regards, -dq

I'd rephrase the latter as: The 8088 has the same 16-bit core CPU as 8086 with an 8-bit wide _external_ datapath. Whats important about the 8088 is it was the first(or one of the first) to seperate the CPU core (control, alu and registers) from the bus interface. Then again you have Z280, an 8bit cpu with an 16bit wide external data path. Hows that for a switch? Allison
