Hello All, > >While I was checking the spelling, I notice that wikipedia mentions >another name for pop rivets is blind rivets. > I _love_ Wikipedia, but it certainly has its share of errors. Please: Never equate pop rivets with "blind" rivets. Blind rivet is a sort of generic term -- meaning that it's a form of rivet that can be used even though you do not have access to the other side of the rivet. Blind rivets are used on commercial aircraft, but only in relatively small quantities -- and -- each catagory of (blind) rivet is carefully chosen to perform a certain task. Most times, when we install blind fasteners (rivets fall into the broad catagory of fasteners), we have to get Engineering approval. Most installations of blind rivets are actually considered temporary. They will usually be removed during a Heavy Maintenance Visit (often several years later). Pop rivets fall at the very bottom of the rivet catagory. Pop rivets are never used on commercial aircraft structure, although I've used a lot of (a certain higher quality catagory of) them to fasten things like nutplates (all they are doing is holding what amounts to a nut, in place, while a bolt is tightened). Once tight, the bolt is tight the rivets are meaningless until you need to remove the bolt again. If the "pop" (type) rivets don't hold, then a veritable stream of cursing insues, while you go and try to find the right drill bits to remove the offending nutplates. Then, the little buggers almost always spin while you curse more and try to get a small pair of ViseGrips on the bottom of them (often very difficult due to space constraints), so you can smash them into submission, while you continue to drill them out. "Cherry-Max" rivets are a very popular form of blind fastener (in this case, blind rivet). They have a solid core of wickedly hard stainless steel that remains in place as the rivet is "pulled" into its compressed final product. Not only are they relatively heavy, they do not expand in the same way that solid rivets do -- plus you now have a dissimilar metal situation. Speaking of pop rivets: There is a kitplane (an excellent work horse of a plane) that makes use of thousands of closely spaced pop rivets. I used to be able to recall its name off the top of my head, but this library computer will not allow me to open another instance of my browser (to search google and figure it out). It was a sort of ugly, boxy, utilatarian looking plane. It was so "ugly" that it was actually very cool!! It's supposedly nearly "indestructable." Oh, BTW, "regular" solid aluminum rivets are only very slightly smaller than their correctly drilled, and in some cases, reamed holes. When the are compressed (bucked), they expand and tightly fill the hole. It's certainly an impressive art to get a properly shaped "bucked" head (also called "shop head"). If the bucked head is smashed too much or "leans" over, you've got to remove them. Technically, you are supposed to go to the next larger size because the material around the hole is now work hardened. If everyone actually removed ever screwed up rivet, there would be little hope of repair at a later time (because you don't have much leeway as to size). I'm pretty sure that that's how ships remained fairly water-tight. The final result of solid rivets are not always perfect. Upon close inspection of any commerical airliner, I can find dozens of leaking or "smoking" rivets. Technically speaking, they should be replaced. Realistically, it's a case of "what are you going to do?" I did a lightning inspection on a 757 that said they were hit on short final. It was raining and miserable (and very dark). It wasn't until the last section of inspection that I realized that I'd forgotten to check a few antennas. One thing led to another, and we eventually found way over 100 affected rivets (and outright holes). The plane was taken out of service for a couple of months, but I saw it again (with lots of very large rivets, which were used to "fill" some of the lightning strike holes). Always choose the correct rivet for the job(!!!). Regards, Robert Greenstreet

One of the incarnations of my cable internet provider didn't allow off net access to POP and SMTP so I discovered that the extensive network of dialups was useful. Under the later revs of their network, you can dial in, authenticate, and then just use PPP to access the internet directly. You get about 3/hours/mo dial-in time for free and usage rates there after. I logged in yesterday via the web.... it takes a little redirection to the "native" Compuserve site as the inital screen wants a "Screen Name" and won't accept a PPN. I thought I set a name for my account but I don't remember it and I didnt write it down anywhere (it was too "obvious" ;^} ) There is a Vintage Computing forum still active, and the files area still has stuff dating way back at least to the 80s. I am still carrying a $9.99/mo legacy subscription, but I don't think they'll let you sign up for that anymore. They now have a BYOA (Bring Your Own Access) rate advertised. I noticed someone in a support forum mention some sort of backup rate of $3/month. I'm guessing that they'll have deals to try to keep getting some money from you if you may quit. I just got a Cingular 8525 and an unlimited data rate, so I'll probably drop this soon. I'm off to learn more about Windows CE. Dave.

wall wart for TI-58-C

At 11:30 -0600 1/12/07, Mike wrote: > I just checked my TI-58C, and it does indeed take a 3.3VAC 500ma power >pack. The links I posted earlier agree. The connector is keyed.

The wart might supply 6.x V open-circuit or low-current, but rely on the battery pack to pull it down to 3.3V at 500 mA, running or charging. The circuit diagram on xgistor seems to indicate there's just a 4.7 Ohm resistor keeping the bus from being completely battery-limited. That said, the battery pack definitely contains 3 Ni-Cad cells, each typically around 1.1 or so V. (I have had mine apart, rebuilt with stock Ni-Cads, ond not fried anything.) Therefore 3.3 V to the electronics makes good sense. One thing I would *not* do would be to plug in the calculator without a good battery pack in place, based on the circuit diagram and on Tony's advice pertaining to the dire consequences of similar actions with HP calculators. FWIW, there is one more factor in the story. TI made a printer base (PC-100?) that you could place the calculator (TI-58, -58C, or -59) on to generate printouts. The method of connection was to take out the battery pack, and place the cavity that it just vacated over a protrusion on the face of the printer, which would then expand to lock the calculator into place. (There was also a compartment to put the battery pack into so it could charge while you printed.) Whatever the power supply in that doohickey was, it circumvented the battery completely. If anyone has one of those and could measure the voltage on its power pins, that would likely shed lots of light on what the calculator expects.

a riviting topic

by jwest＠classiccmp.org

>From time to time, I've wondered about riviting whenever I come across a piece of computer cabinet metal that has rivits that have come loose or fallen out. The current case in point is the tilt latch on an 11/44 when it's in the 11X44-CA configuration (it's in the top of the rack, and tilts up on gas pistons). There is a little latch on the side (best way I can describe it is a metal rectangle cut on a diagonal) which is spring metal. You pull this latch in from the front with a pen or screwdriver, and it then clears the tab on the outer rack so it can tilt up. At the very back of this spring metal latch is a rivet holding it in place. This rivit has come loose. You can really only get to one side of it, that's when the cpu chassis is tilted up. I believe that in other (more common) rackmount configurations of the /44 when it's on slides that telescope out the front, this same latch is present but it's used to allow the cpu to slide forward rather than tilt up. I've seen riviters working on F18's at Boeing, and it sure appears to be a higher art form. Not sure it's something I could do, but thought I'd ask here. I've seen all kinds of rivits - different sizes - on an H960 I believe there are a couple? Anyways, what tools are required, where can one get rivits, what different types are there, and is it something a neophyte like me who has never done a rivit before can do? I'm looking for the basic intro to replacing a rivit for someone who has never done it. Jay West

HP11284 (or HP11285) datacomms interface

by ard＠p850ug1.demon.co.uk

Another of the interfaces I purchased is called an HP11284 data communications interface, it's part of the 11285 datacomms option (which also included firmware ROM modules for the HP9830). Anyway, this thing is complicated. It's 2 modules that plug into the 9830 I/O slots, each contains a PCB. One is stuffed with TTL and RS232 buffers (1488s and 1489s), the other has more TTL and 4 custom ICs. 2 20 pin ones (no idea) and 2 40 pin ones (maybe transmitter and receiver logic). The modules are linked by a cable, there's another cable from the first PCB I mentioned to the podem (or whatever). It ends in a 36 pin microribbon connector, I believe there was another cable which I don't have that connected to that and which ended in a pair of DB25 plugs, one for the RS232 signals to the modem, ther other carrying RS336 signals to an aautodialler. My first question is simple. Does anyone have this interface with that last cable and could 'buzz out' the connections so that I can make said cable, and/or figure out a little of the internal hardware? -tony

Looking for a service manual for the HP9865 cassette drive

by ard＠p850ug1.demon.co.uk

Well, the subject: line says it all really, but I'd better explain if only to avoid the 'You should be able to figure it out for yourself' (I could, if I have the drive) and the 'Most of it's the same as the drive in an HP9830' (it is, but it's the different bits I am interested in) type of replies. I've bought a few interfaces for the HP98x0 series of 'calculators' [1]. One of them is the interface for said tape drive, it's a single PCB containing about 10 TTL chips. What I am looking for, though, is a pinout of the interface connector on the drve iteslf so I have some idea what to expect on the end of this interface's cable. [1] They're called 'calculators' to get past the purchasing depatrments of the time. They're really computers -- the 9830 in particular programmed in BASIC, has an alphanumeric display and supports HPIB and I believe a hard disk. Other machines in the family (9810 and 9820) are more like calculators, but haev the same bit-serial 16 bit proceessor, etc. -tony

HP 21MX/F and OS choices (was Lookee what I just got!)

by MGemeny＠pgcps.org

Should be TSB and IPL Bob, TSB assumes that it is the OS, so it is assuming that it ?owns? all of its peripherals, DMA and the Interrupt system as well. As long as these false assumptions are accounted for under IPL I would think that a single CPU TSB such as TSB E may run without many problems. The real problem comes with dual processor configurations of TSB. Ether processor can initiate communication to the other, although the Main is generally the one ?Calling the shots?. Ether way, they assume that their partner is listening attentively, and they don?t have much tolerance for a sluggish response. If ether one gives up on the other the result is DEATH. Under SIMH we had problems getting the timing right between the two virtual processors, but it does work, and on some platforms it still needs tweaking. On real hardware if you stop all user activity, you can get away with halting the Main processor, exploring memory from the front panel and pressing Run without causing a crash. But if any terminal were to strike a key while the Main was halted the IOP would give up on the main and die, when the main came back the IOP would be dead, so the Main would die too. If you try to halt the IOP with the system running the result is always death. I think that it may be the result of a lost clock interrupt, because we see the same thing under SIMH. TSB is rather particular about addresses of it IO devices, so running both processors on the same CPU may take a bit of creativity when allocating devices. The IOP of Access would give you the most flexibility, but it?s still rather strict. On the 2100 version of Access the IOP microcode went into the same sockets as the Main Processor?s floating point microcode so they were mutually exclusive and both required, but on the 21MX versions I think that was changed. So it may be possible to have both floating point instructions and IOP instructions in the same CPU. Although I seem to recall that the IOP instructions needed a stack pointer, and since they were not using some register of the memory subsystem they just used that register for the stack. I want to say that it was a ?memory fence register?, but I?m not sure. And the IMS that describes it refers only to the 2100a/s microcode, so I really don?t know what they did in the MX microcode. It?s possible that the IOP microcode for MX may interfere with something that IPL is counting on and Jay, Al, or Bob may be the best people to speak to that. Of course, this would only apply to real hardware, under SIMH the instructions are simulated without the constraints of the real hardware. It would be really cool if the interconnect kit (the channel between the two processors) could be virtual through IPL and perhaps even cause the change of context to running the other processor. The device drivers in the IOP are well organized, but the Main Processor is not. Sometimes it looks more like spaghetti code, with IO instructions all over the place in seemingly unrelated routines. (I?m sure they did that because they had both memory and CPU time constraints, ;-) None the less, my hat?s off to them. The last version of HP2000 Access had only one bug found in it that I am aware of. With that bug patched, I don?t think any other bug has ever been found. I don?t think I shall ever again see such perfection. On the special boot strap loader issue for Access, I don?t see it being a problem. We don?t use it or even load it under SIMH. We just let SIMH load the second half of the bootstrap paper tape image in low memory of the Main processor and start it. We also let SIMH load the whole image of a preconfigured IOP and start that. Sure someone could change the SIMH startup scripts to be absolutely true to the recommended boot procedures, but then again, a lot of these short cuts were well known back in the day of real production systems and we are trying to boot the system with minimal operator intervention. TSB E sounds like the place to start. Then I would try Access on two CPUs then each running under IPL. And finally Access with both running on the same CPU. If you decide to run tests with IPL and TSB under SIMH I would also caution that the simulated interconnect between the two processors has only (as far a I know) been working under Windoz. I think it has something to do with the ?Socket Connect? library code, which last I checked was only used by this device. Some day some other device may use it, and someone may take the time to fix it. But for now we are just so happy to be able to run dual CPU TSB that we put up with running it on Windoz. The quickest way to boot up a TSB E system is under SIMH. The URL for the ZIP is in the links section of the HP2000 Yahoo Group. The binaries are images of original HP paper tapes (Thanks, Al and Jeff), so they should be quite useable on real hardware if ported to a suitable media. Hope this helps, Mike Gemeny

I get the impression that it's not as good a the sort used in manufacturing, but for this kind of purpose, I'd think it would do fine. The basic tool is a squeeze handle device. You take a rivit that has a shaft running trough it similar to a finishing nail with a bulge on the inside end of the rivit. You put the shaft into the riviting tool and insert the rivit into the hole. When you squeeze, it pulls the "nail" inward and the bulge streches a cylindrical part of the rivit pressing it against the back side. Then the tool cuts the "nail" and the two pieces are tossed. What's left is the rivit pressed in place. I think most tool shops carry these as well as supplies of the rivits. BLS

DEC beige/creame/white paint

by jwest＠classiccmp.org

I have the top panel of an 11X44 that is pretty scuffed up and needs some paint. That's the white/beige/creame color on the DEC "corporate cabinets" (not H960's). It is also the same color as the front of an RL01, RL02, RAxx, etc. Before someone says "just mount the RL0x at the top", that wouldn't be appropriate since this is an 11X44 configuration (11/44 cpu at the top with a full length door under it that has an opening for two TU58 tapes). The scuffs on the top panel are pretty bad so just a "paint stick" type of approach won't help. I'm going to be looking at wax & grease remover, sanding, self-etching primer, chipguard, and paint. What fun. In addition, I also have a lot of tiny touchup spots on various boxes - mostly the front of RL0x's - that needs just a tiny "paint stick" type of approach. So I took the panel into a metal paint shop in town well known for their expertise to see about getting the paint matched. They said that since the top is textured, the peaks & valleys will look brighter/darker and thus you can't put a piece like that on one of those optical scanners and get a good color match. They said it may give a starting point but it'd have to be matched by hand (eye) because of the type of textured surface the panel has. To come up with an exact match paint (done by hand/eye), I could get a quart for $50.00 USD. Then from that quart I could have spray cans made (they put custom paint in spray cans) at $7.00 each. I would envision having perhaps a can or two made for spraying, and leave the rest in the quart container for "paint stick" type of touchups - when there's a small scratch that just needs to be dabbed with a matchstick, etc. Since I know absolutely NOTHING about paint/painting, I wanted to toss this out on the list to see if what this place is suggesting sounds right, and if the prices seem reasonable. If so, then I also wanted to offer some spray cans of the paint to other listmembers to help defray the cost for myself. I know that one can probably buy a color that is sortof close right off the shelf, but I'd rather have an exact match... Thoughts? Jay West

Strange disk controller in my new 8/A

by v.slyngstad＠verizon.net

Hi, I recently received my new PDP-8/A that I bought on eBay. The good news is that it arrived in useable condition, and comes with a 10Mb disk drive (Shugart 4004) and high-speed paper tape reader. The bad news seems to be that the software is all specific to the machine's former life as a CNC machine controller (MM180). The configuration seems to start with a standard 8/E cpu with EAE in the 8/A chassis with 32K of memory and the usual option cards. But for the disk and tape (which were the exciting parts, for me), there is a 3-card set with a 6800 on it that controls the disk, the paper tape reader, the CNC servos, and a bunch of other stuff. Effectively, all the non-console I/O is given over to the 6800 as a kind of I/O processor. Anyone have any experience with these? The 6800 board is KT (Kearney & Trecker) 1-20410, the board with the PIO chips is KT 1-20411, and the disk interface board is KT 1-20666. Thanks, Vince

Hello, Jay, especially, but any other HP types, Well, I went and did it. I am now the proud owner of an HP-2117F, if I can identify it correctly, shown here: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320067174880 ... and, FPU, shown here: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320067174671 My experience with the HP 1000 series machines is, almost exclusively, programming them in TSB on HP-200B, C, and F systems, many moons ago. Jay, you seem to be an alpha geek when it comes to HP iron. (A term of respect, no offense intended...) So, could you look at the above auctions, and tell me what I need to make a good system. Obviously, a disk system comes to mind... but, if you could be specific, I would appreciate it. Also, what are the chances of this being a suitable machine to run Time-Share BASIC, or TSB? I imagine I would need microcode boards or ROM for the microcode boards already there, but, for all I know, it already *IS* a TSB machine. Thanks for your consideration. Peace, Warren E.

DEC beige/creame/white paint
