AMD used 91xx for RAM, 92xx for mask ROM (with a couple of exceptions), and 97xx for EPROM. AM9217 is an NMOS 2048 x 8-bit ROM; A is the speed (550ns), P means 24-pin plastic, C means commercial temperature range (0-70 Celcius). Pinout is the same as an 8316, 2716 compatible, but the chip selects on pins 18,20,21 can be specified either active-high or active-low. The AM9217 was superceded in the late 70's by the AM9218. -- Pete Peter Turnbull Dept. of Computer Science University of York

Here's the table from the User's Guide: Green Red Drive state -------------------------------------------------------------------- Off Off power off Off On 1. After power-on, this condition occurs for 5-15s while the drive is initializing. (Red goes off and green comes on after initialization.) 2. Indicates handle is up, following cartridge insertion. 3. Indicates tape has almost completeed rewinding, and is approaching the unload point. Red stays on during this sequence (8-10s). On Off OK to lift handle NOTE: Only under this condition is it safe to lift the handle. Under any other condition, lifting the handle may damage the unit or cause a fault. On On Tape is at BOT and drive ready to accept system commands. Flash On Indicates tape motion during normal system operation. Flash Flash Tape is rewinding to BOT. Flash Fast Indicates a fault condition. See Chapter 5, Solving Flash Problems. Pushing the LOAD/UNLOAD switch FOUR times may clear the fault. Chapter 5 suggests trying the four-presses two or three times. If that doesn't work, power off and then on (it says to do this only once, actually). If that doesn't work, it suggests calling your system administrator, Field Service, or removing the drive to send to a Service Centre. Not very informative or helpful, really. The only chapter that's shorter is Chapter 4, "Uses For The TK50". The load sequence is: If the power is off, make sure the LOAD/UNLOAD button is in the OUT (unload) position, and power up the drive. Let the drive initialise: the red LED should be on for between 5 and 15 seconds, and then the green LED comes on and the red one goes off. When the green LED is on and the red is off, lift the handle. "Caution: never lift the handle if the red LED is on or blinking." "Smoothly and completely insert the cartridge." [the manual doesn't say where, but I'd be tempted to find the nearest convenient member of the TK50 design team, and ask them to turn round...] When it locks in place, the red LED should go on and the green LED off. Lower the handle. After several seconds, the green LED should come on steady, and the red LED should go off. At this point, it's safe to operate the handle again to remove the cartridge, or continue to load the tape. Push in the LOAD/UNLOAD switch (the LOAD position is IN). The tape shuold go through the load process, taking 5-8 seconds. Both LEDs come on steady when it reaches BOT. To unload a cartridge: Set the LOAD/UNLOAD switch to OUT (UNLOAD position). If the tape isn't already at BOT, both LEDs will flash *slowly* while it rewinds. If the tape was very cose to BOT, you might not see them flash. The red LED comes on while the tape is unloading from BOT. This should take 8-10 seconds, then the red LED should go off and the green should come on. When the red LED is off and the green is on, left the handle, which partially ejects the cartridge. ----- The manual has some diagrams showing how the tape leader in the cartridge should look, and how the take-up leader in the drive should be. From what you wrote, I don't think you have any problems here, but for the sake of completeness... I'm not going to attempt ASCII art for this, and I'm afraid I can't get at a scanner ATM, so I'll try to describe them: Cartridge: Looking at it right-side-up, with the edge with the door towards you and the hinge at the right, you should be able to release the door lock by lifting up the release. Swing open the door; you should see the leader on the left, with *nearly* all of the eye in the leader showing. Drive: With the handle down, looking into the cartridge slot, you should see the take-up leader, with its notch roughly in the middle of the slot. To the left of that notch, the take-up leader should be a little less than 1/2" wide; to the right of the notch it narrows to a fraction of that (maybe an 1/8"), with a sort of fat arrow-head on the end. A little hook on an arm behind the takeup leader (called the buckling link) should be hooked through the notch. Just at the back of the hook, on the buckling link, are a couple of vertical pins which prevent the takeup leader sliding too far back up the buckling link. The narrow part of the takeup leader should all be in front of the link, and straight; it should not be displaced above the link, nor tangled in it, nor unhooked. -- Pete Peter Turnbull Dept. of Computer Science University of York

The TI-PC was released in 1984 not too long after the world famous TI-99/4A rolled over & died. The machine itself is a partial IBM-PC clone, but is not completely compatible as it uses a proprietary disk format (reminds me of an AT&T PC 6300/6400), & it's own version of DOS (TI-DOS, to be exact). The machine reportedly had excellent graphics hardware (for the day, anyway), & one of the best early PC keyboards anywhere. I have only seen one of these things "in the flesh", & that was a few years ago (either 1997 or 1998) in a getting repaired (!) in a Radio Shack.

If you try to run RT-11 5.5 or 5.6 on an 11/20, you'll get some complaint because EIS instructions found their way into a few utilities and drivers.

More interesting TK50 fun

by cmcmanis＠mcmanis.com

Ok, so I had an old TK50Z-GA that was marked "dead" and I ripped it apart and discovered a couple of blow caps on the "heater" board :-) (some adjunct to the PSU) replaced those and it seems to work somewhat again (I've not hooked it up to SCSI, just powered it up to see the drive light up) Anyway, I took my other drive that I was powering up on the bench and by wiggling out the TK50 connector and the power connector I can now plug this thing in an watch it in "real time." This has yielded a bit more information about the failure mode of the drive. With the cover removed I can watch what the drive is doing. This is what I've found out. The "hook up" leader was around the spool and out of the feed path. Now when powered up the drive turns the spool a bit and then starts spinning it making the leader thingy go whack whack whack on the edges. (DEC weed whacker! :-) If I re-feed the take up lead through the tape path it moves back and forth a bit and then stops with the red light flashing. [Note to Tim: My test tape is a scratch tape] Then I fed the tape in manually and hooked it up to the leader. Now the tape was taken up on the spool a bit, then it rewinds to what might be the load point and stops. Then the red button flashes. If I try the press and release a few times leaving it in the unpressed position the drive feeds some time then rewinds and stops just as the end of the actual tape (beginning of the pick up lead) reaches the capstan. [Reference Picture : http://home.mcmanis.com/images/tk50-2.jpg ] In the reference picture I circled in Orange where the leader stops and in red where I cleaned with a q-tip. I've confirmed with my IR detector that the LED in the lower right side of the picture (more toward the rear) is emitting. So several questions come to mind. I'll pop out some of the obvious ones... 1) Does the Red Light/Button on the right hand side in the "out" position mean "unload" ? 2) When does the green light come on (except on power up when it is unloaded.) ? 3) It appears that a "working" unload sequence would have the tape leader get sucked back into the tape and the 'unhooker' should engage the hook leader. Why would it stop before it got that far? --Chuck

Honeywell 316s? Re: Honeywell Level 6 Mainframe

by aek＠spies.com

"What does the formatter box look like?" Pertec formatters are about 3" high very boring looking rack mounted boxes. They may have been used with an internal 2315 style disc interface in the 316. The drives themselves are 2.5 mb (or 5 if there's a fixed disc underneath the removable) 2315 style devices. If they're the original Pertec Blue, I would suspect someone would want them for their Altair 8800b's

TK50 redux

by cmcmanis＠mcmanis.com

Well I discovered the problem. The extender arm that is engaged by the cartridge when it is inserted has been bent. (Perhaps someone tried to shove a cartridge in without the handle lifted.) Anyway, without a replacement part the TK50 is not going to work again. Strangely, I went into another pile and came up with another E4 rev TK50 that had a different problem thinking that I might get the piece I need. No such luck, the mechanisms are quite different. There must be a zillion ECOs on the TK50, I don't think any two out of 6 present are identical. Well I've got four working ones and two dead ones. Other than the leader grabber, what other parts might be good salvage? (The hulks will stay in my scrap pile but at least they are now 'down for the count.') --Chuck

TRS-80 Manuals/software to trade.

by ernestls＠home.com

I have several TRS-80 user manuals with the original software to trade or sell. I would like to trade them for something of a vintage computer nature. I'm a general collector of vintage computers so anything of interest will be considered. If no one wants them, then I'll stick them on Ebay. These manuals are all in good condition, and the disks are all 5.25 size. 1. Model 4 Disk Sciptsit Ver. 1.00 -this is a word processing program for the TRS-80 Model 4. It lets you type, proof-read, revise, print, and save. This program is in it's original :SFD box, with the user manual, reference card, registration card, etc., and the original software disk (for TRSDOS 6.01.00.) (1983) 2. Model 4 TRSDOS 6.2 Utilities Manual -this is the original large, brown vinyl notebook binder (catalog #26-0315.) It includes the original TRSDOS 6.2 Utilities disk, in the inner sleeve pocket. (1983) 3. Model 1/3 Hard Disk Operating System Manual -this is the original large, brown vinyl notebook binder (catalog #26-1130.) This manual explains how to setup, install, and operate the Hard Disk System using LDOS, on the Model 1 and Model 3 computers. This is a thick user manual, and it includes two original disks -Model 3 Hard Disk Operating System LDOS Ver. 5.1.3, and the Model 3 Hard Disk Operating System Initialization Disk LDOS Ver. 5.1.3., in the inner sleeve. 4. Model 4 Disk System Owner's Manual -this is the original large, brown vinyl notebook binder (catalog #26-0316 I think.)This manual explains how to use the Model 4 (with floppy disks,) and how to use TRSDOS Ver. 6. It includes the original TRSDOS Ver. 6 and BASIC Interpreter Disk. (1983) 5. Model 4 VideoTex Plus User Manual -this is the original large, brown vinyl notebook binder (catalog # 26-1598.)

TK50 failure analysis

by cmcmanis＠mcmanis.com

Ok, so I've come up with a plausible explanation for my TK50 problem. Apparently the drive thinks there is a tape cartridge in it, even though there isn't one. It runs the classic "loading sequence" (slow uptake then fast uptake) even though there isn't a cartridge present. That suggests that it is mistaken about the presence of a tape. So, does anyone know what all of the methods are the TK50 uses to sense the presence of a tape? I'd like to get this one fixed as it is an E4 (I've got two B2's, one E3, and working E4 and one dead E4) --Chuck

RX01 Bootstrap Loader

by allisonp＠world.std.com

<KL11 setup: addr: 777560 , vector: 60. That is a majik address. 176560(16bit address) and vector 60 is the default console for any KL/DL or similar device. It is insensitive to what the device generally is but the basic status and registers must be there. RT-11, XXDP and friends expect it unless the particular copy was built for an odd address, then console ODT (for those that have it) will not be available and the console cannot control booting. Not a good idea to do that by the way and you can only do it on the non-microODT processors. Also RT-11 (any version I have played with) MUST have 8kw of memory, again you can custom build for smaller but for limited application only. The smallest almost OS was the IOX package (IO Executive) for embedded apps, the Micropower pascal system could build for small memories. Allison

Nortel modem-terminals/display phones

by bill_r＠inetnebr.com

Next time I'm at the location where they're stored, I can try to find you a number. They're RS-232, but they're a bit funky to get to work with anything else; I don't remember the details, but it seems like they used really odd settings - like 6 bits, mark parity, 2 stop bits. Also, the attached phone only works with Northern Telecom phone systems, unless you were to gut the whole thing and stick the electronics from a one piece phone in them. What I've decided to do for terminals around the house (including the kitchen and bathroom) is to buy some old 486 laptops with color displays and PCMCIA slots. I've got PCMCIA ethernet cards for them, and am shopping for PCMCIA sound cards. My plan is to run Linux or FreeBSD on them, and X-windows, and let them surf the web as well as accessing our answering machine (which runs on our file server, and is already web-enabled), Mister House control console, and the CD jukebox control software. I'm going to *try* to set up either a Real Audio server or some kind of multicast audio server, and have a sound card in the server sampling and digitizing the output of the CD jukebox and the computer-controlled FM radio tuner, so you can "tune in" from any workstation in the place and listen to the radio or CDs.

TK50 gymnastics

by cmcmanis＠mcmanis.com

Ok, so now that I've got a mini TK50 test bed set up I tested three other TK50s that I had in a box "condition unknown". After cleaning out some killer dust bunnies they all seem to do the write things. For the archives, TK50 behaviour is as follows: Power on (empty) hums a bit, Red light on. Red Light push button should be in the "out" position. Internal tape spindle moves a bit. Solenoid goes "click" and green light goes on (red off) Lift handle, slide in tape, close handle. Light stays green, nothing happens. Press Red light/button into the "depressed" position. Green light goes off, tape begins motion. Whir, Whir, grind grind grind, tape stops green light and red light remain lit. Use tape in this mode, when finished... Press Red light/button to the "out" position. Tape moves a bit then rewinds rapidly. Tape slows, light flickers, "click" Solenoid retracts and green light goes on. So my broken drive doesn't want to put the leader into the "load/unload" position. Instead the tape stops before it gets completely unwound. I've been using the same tape on all drives so that eliminates the tape as a candidate for now. --Chuck

More interesting TK50 fun

by CLASSICCMP＠trailing-edge.com

>So several questions come to mind. I'll pop out some of the obvious ones... > >1) Does the Red Light/Button on the right hand side in the "out" position >mean "unload" ? Yes. >2) When does the green light come on (except on power up when it is >unloaded.) ?

Why >would it stop > before it got that far? While it's doing its tricks, look carefully at the metal capstan that the tape and leader goes over at the rear of the drive. There's an optical interrupter connected to the shaft of this, and this is the only way that the TK50 knows that the tape is actually moving. If tape or leader is moving over this capstan without turning the capstan, the TK50 drive gets all confused and gives up. So look carefully to see if that capstan is turning as tape gets pulled over it. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

Yes it's ten years old...but it's a piece of test equipment, not a computer, so it's only getting "a little" old at this point. Newer units are a bit more flashy and flexible, but those newer units also tend to be Windows PC laptops running network analyzer software that some college schmuck threw together in Visual Basic...and thus tend to blow up a lot. The HP4972 isn't a Windows PC in disguise...it's an honest piece of application-specific- engineered test equipment that does its job very well. I have the documentation, and I'd be willing to loan it to you. I also (obviously) have the software...I'm not sure how to copy it out of the machine, but if we can figure that out, I'll help you get yours running. FYI they tend to go for anywhere between $500-$1000 (working) on the surplus market, or up to about $2500 in the "commercial" used test equipment market. -Dave McGuire

V chip (was: Going totally OT )

by edick＠idcomm.com

Well, here in the Land of the Free, there's too much exercise of freedome not guaranteed in any document anywhere, and not tolerated in countries in Europe. It would be so much simpler if there were only one punishment for all violations of the law, as so many infractions are worthy of that ultimate punishment, DEATH. The only thing that seems to vary is WHOSE death. If every offense were met with immediate extermination, perhaps followed by a posthumous apology, a lot of people would behave differently, and nobody would park in my reserved space. In civilized countries, and NOT the U.S, it's common for citizens to turn in their neighbors for viloating the law simply because they observe a law being broken, and not because it has effect on their lives. The fact is that HERE, in the U.S. a person picking up the phone and notifying the police that there's a minor crime in progress within his view is considered, even by the police, worse than the offender. In the U.S. the observable lack of civilization is evidenced in the inability of people to inhabit a limited space as the Europeans have known for centuries to do. For us Americans, it's growing pains. Since there's no more land to inhabit, we're having to acquire some traits of civilized societies because we're having to live together with more and more strangers, often quite different form ourselves, racially, culturally, linguistically, etc. Over time we're going to have to move in the direction of the European model, which we know works, and rely more on common observance of law as opposed to trying to circumvent it.

V chip (was: Going totally OT )

by mgregory＠vantageresearch.com

I don't know the technical details, but here's my understanding: The V-chip is a device that will be installed by law in every VCR and TV manufactured in the U.S., which will allow parents to selectively block content that they find objectionable. So, for example, if I think it's o.k. for my child to see a little bit of romance and sex, I could set the "Sex" limit to 2 out of 5. If I wanted to block all violent programming, I could set the "Violence" limit to 0 out of 5. The device would detect the Sex and Violence levels of all incoming programming (I don't know who would rate the programs). If the program is over the limit that I've set, the device blocks the TV or VCR from showing the program. Of course, given the number of people who can't even figure out how to program their VCRs, I suspect that the kids will be better at changing the limits than their parents - I presume that the system includes passwords or something to prevent unauthorized changing of the limits. I believe that the V-chip concept was invented by a Canadian company, but I may be wrong on this.

I needed to boot RX01s as that is a lot easier to run diagnostics across a bunch of 11/20s quickly... beats paper tape!. I have some old diagnostic disks/diagnostic code on RX01s for the 11/20. Most of the PDP-11/20s I am restoring have serial numbers under 400 so most manufactured at that time were configured with paper tape and 4K core. Most of the 11/20s I got were configured with paper tape/4k core. The *newer* ones have DECTape. I am testing all the PDP-11/20s after a basic rebuild with 4K core.. I will add more MM11-Es depending on what is requested. Due to the instruction set incompatibilities between the 11/20 and other 11s, will they even run RT11 V30B with 8K core? I expect most will probably just want PTS-11 and DOS/BATCH with an 8K core system. john PDP-8 and other rare mini computers http://www.pdp8.com >-- > Tim Shoppa Email: shoppa(a)trailing-edge.com > Trailing Edge Technology WWW: http://www.trailing-edge.com/ > 7328 Bradley Blvd Voice: 301-767-5917 > Bethesda, MD, USA 20817 Fax: 301-767-5927 > >

Exactly. This government is very big on "protecting the stupid". Personally, I see it as "fighting Darwin"...natural selection can do the right thing if left to its own devices. Now, I don't have kids, so I'll not pretend to be an authority on the subject...but it seems logical to me that keeping them informed will go a lot farther than censoring the world for them. How many people here *really* learned about the "birds & bees" from their parents? Wow, this IS off-topic! -Dave McGuire

Sorry about the title on the previous post. Darn spell checker gets a little carried away sometimes.

It appears to connect via RS-232 to a dumb terminal for its output of such things as address and data, and perhaps input of some parameters such as uP clock rate; baud rate is selectable from a thumbwheel. This system also appears to have the capability of single stepping the program contained in the device in the ZIF. It has a 28 pin ZIF socket for the targets EPROM/PROM/ROM. There is a standard ribbon cable that connects to a pod, and the pod has a braided ribbon cable that terminates at a 40 pin dip header, most likely to attach to the target in place of the uP. Trap conditions are selectable via four 0 to F thumbwheels, and conditions to be triggered on can be selected as memory data read, memory data written, and/or op-code.

Dumpster stories!

by thomas.h.lindberg＠se.abb.com

A coule of years ago we had two very tragic dumpster stories in Sweden, three kids vere killed while reading magazines in covered newspaper/magazine dumpsters. The kids had seaked in through the narrow opening where we dump our old newspapers/magazines and sat there while the truck came to pick up the dumpster content. The dumpster was automatically emptied into a compacter at the truck and all taken to the fragmentation site where the kids wer found crushed. The dumpster openings are now just about the size of a mail box. Thomas

US customs holding/rejecting computer material.

by dylanb＠sympatico.ca

US customs has decided that people/companies in the US are avoiding tariffs by "importing computer components through Canada" ... even if they are over 30 years old. I (and others I know) in Canada have had quite a few problems (just over the last two months) shipping computer components and documentation to the US. My last eBay buyer spent quite a bit of time trying to convince US customs they were not trying to avoid tariffs... [these materials were well over 25 years old] I wanted every Canadian List member to know that if you indicate the contents of the package to contain computer parts/manuals then, no mater how old, these items could be held up in customs or rejected if you don't provide contact info to customs. (customs doesn't seem to have a clue that *old* computer parts fall outside their tariff issue). Since computer parts are "electronic boards/parts" and manuals/documentation can fall under "books" I recommend describing items as such. Shipping whole mini computers are another issue. Generally, make sure both phone numbers are on the parcel so US customs can contact the shipper/buyer immediately with their concerns. Good luck! john PDP-8 and other rare mini computers http://www.pdp8.com

My first experience with this was a $120 item I bought for my Amiga from a small company in Vancouver. I get this call from so-and-so brokers who want $85 to process my paperwork. I was outraged.

I did receive my hardware a couple of weeks later by post with no duty and no problems. My employer at the time used to ship magtapes to Canadian customers via UPS with the proper customs paperwork attached. We never had any complaints, but we knew how to fill out the forms properly. The moral of the story is to *never* send items across the border UPS without any customs paperwork. The recipient will be saddled with the consequences. -ethan ===== Infinet has been sold.

>US customs has decided As with all bureacracies, trying to make a blanket statement is difficult and usually wrong... > that people/companies in the US are avoiding tariffs >by "importing computer components through Canada" ... even if they are over >30 years old. Do you have a particular source for this information? I'm not saying that you're wrong, I'm saying that I want to learn more. If there's some specific directive number that'll be particularly valuable. >I (and others I know) in Canada have had quite a few problems (just over the >last two months) shipping computer components and documentation to the US. Oh, absolutely. I've had Canadian *government* customers with their media turned back at the border because the US government couldn't make head or tails of what it was. (These were 8" floppies and paper tapes, BTW.) That particular governmental agency now flies the media down in an employee's luggage. >I wanted every Canadian List member to know that if you indicate the >contents of the package to contain computer parts/manuals then, no mater how >old, these items could be held up in customs or rejected if you don't >provide contact info to customs. (customs doesn't seem to have a clue that >*old* computer parts fall outside their tariff issue). You're using the wrong language. If you claim to US customs that what you're doing falls outside their scope, you're only going to convince them that what you're dong is something that they should be concerned with. This isn't an attitude unique to US customs, it'll happen with most any customs service. In particular, to a customs officer "old" often means "potentially antique and valuable". And I've had Canadian customs officials explain to me several times that "zero value" is not possible. If it had no value, you wouldn't be trying to ship it. >Generally, make sure both phone numbers >are on the parcel so US customs can contact the shipper/buyer immediately >with their concerns. Absolutely.

V chip (was: Going totally OT )

by mgregory＠vantageresearch.com

Here's a resource - not much technical detail, but explains how the system works better than I did: http://www.vchipeducation.org/index.html This gives some of the history of the idea: http://www.primenet.com/~acacia/soundview/Bio.html Apparently, the V-chips are only installed in Televisions, not VCRs, and some content (e.g. news, pay-per-view or cablesystem movies) is not necessarily rated. And the system uses the "Closed Captioning" signal to convey the program rating information.
