Where the cool stuff is (was: Re: DEC Vaxstation II GPX needs a home)

by xds_sigma7＠hotmail.com

There's no bids on it because its not worth $300... they make no mention of having any software or docs, which would make it damn hard to use.. Not to mention that they don't say what the hell kind of computer it has an interface for on it... could be set up for a lot for a lot of different things.. and it's also a huge beast of a thing to ship. That things been on ebay like 3 or 4 times now Will J ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

Removing surface-mounted ICs

by mark_k＠iname.com

Hi, This isn't strictly on-topic, but I guess it could be applied to maintaining classic stuff, so... Can anyone recommend a way of removing surface-mounted ICs (specifically SOJ package DRAM chips) from a board? It's not critical to keep the board undamaged, but the chips must be kept intact since I want to solder them into another device. I read of a technique involving turning the board upside-down and heating the board area opposite the ICs in question with a blowtorch. The ICs drop off when the solder melts. I don't have a blowtorch, but do have a gas stove. Heating the board over the stove will probably not be a good idea, since the ICs would need to be lifted off when the solder melts. Since I want to recover several chips, they are likely to get too hot doing it this way. I do have an electric grill. The element is at the top of the oven. What about putting the board component side down in the oven (near the heating element), and heating until the solder melts? It will be important to get the temperature profile right here, I think. Putting the board straight into a hot oven might not be a good idea, but on the other hand having it in the oven as it warms up from cold may be too long. In a way, doing this would be similar to IR reflow soldering. What is a typical melting temperature for solder used on surface-mount components? The oven control goes up to 260 Celsius (from memory), which I hope is high enough. Has anyone else attempted something like this? Do you have any advice? I guess the same technique could also be used for soldering surface-mount components (with board component side up, and solder paste applied to the pads). -- Mark

Tech Rumors/Legends?

by dcoward＠pressstart.com

Hi All, One the nice things about this list is the variety of first hand experience that can be called upon to clear up those nagging second hand rumors that you keep dragging around for years, unable to track down a definitive answer. Up for review: 1. "The person that designed the Mindset PC later designed the Amiga." I realize that computers like the Amiga are not designed by just one person, but does anyone know anything about the people that helped design these computers? 2. About 1982 I started hearing that it was possible to build a camera for your pc by "cooking" an EPROM under UV light for an extended period until the memory cells were still light sensitive but would no long hold a charge. Then by placing a len over the EPROM's window, you had a real time low-res video image mapped right into memory. Again this is one that quite a few people had heard about but no one knew anyone that had ever done it. 3. This has probably been discussed here before, but .... I've heard that the old 8 inch 32 sector hard sector floppy diskettes, the ones with the sector holes around the outside edge of the diskette, and the big notch in one corner, is is an early version of the 8 inch floppy - maybe the first form the 8 inch floppies from IBM took. 4. I've heard somewhere, and the source is lost to age, that - the Altair for the January 1975 article was just a empty case and that no regular orders for the Altair 8800 where filled until April 1, 1975. (Sure, I drooled on the magazine at the time, but it might as well costs a million dollars, I was a single sailor collecting $151.00 every two weeks, saving to get married at the end of April.) Comments welcome, I would like to deallocate the space for the ones that have no real basis in fact. Regards, --Doug ========================================= Doug Coward Press Start Inc.

Defining Disk Image Dump Standard

by CLASSICCMP＠trailing-edge.com

>> This is a good start. The header should include a byte that contains a >> flag indicating the status of the sector (good, bad, etc). >Other things that are 'missing' from that header are whether the sector >is single or double density, what sort of Data Marker came before it >(some TRS-80 disks use strange data markers, and just about all TRS-80 >M1/M3/M4 OSes use deleted data markers on the directory track). Then there are some *real* oddballs, such as disks with 18 or 12 or 9 bits per byte. It's very, very common for double-density CP/M disks to have the boot sector - and in some cases the first few tracks - in single density. For these odd formats, I just record the waveform from the head for each track for a couple of revolutions, just to make real sure that I'm not missing anything :-). Tim.

Need Software.

by netsurfer_x1＠hotmail.com

I am putting out a call once again to anybody who has any DOS software (and I mean anything at all: Word processors, games, scientific programs, etc.) that will work on a Sharp PC-7000 lunchbox portable. I think it has 384K, or so, of memory, but programs that run in 256K should be enough for the job. I also runs DOS Ver. 3.2 I *do not* want to have to sell or scrap this somewhat rare (well, for a PC, anyway) machine because I have no software for it aside from the boot disk. ____________________________________________________________ David Vohs, Digital Archaeologist & Computer Historian.

DEC power control? How do it know?

by cmcmanis＠mcmanis.com

Ok, I'm cobbling together a PDP-11 and I ran out of slots on my BA11 so I put a bus extender into it and plugged that into a BA23. The system works fine (thank you micronotes!) but I'd like to figure out how I could set it up so that powering up the 11 powered up both the BA11 and the BA23. Now I know the little 3 plug do-hickey (I think it is a mate-n-lock) normally connects to a power sequencer in the rack, but I don't have one of those. Is there any way to make it work otherwise? --Chuck

Tektronix 4014 HV PSU

by rdd＠smart.net

A while back, when I turned on the power to my Tektronix 4014 terminal, nothing appeared on the screen, but I smelled an acrid odor. Upon closer examination, the smell came from the terminal's HV PSU board around the HV transformer for the CRT circuitry. Is this a common problem with these terminals? I'm hoping that the CRT hasn't shorted out, but I haven't had a chance to check that yet. -- R. D. Davis rdd(a)perqlogic.com http://www.perqlogic.com/rdd 410-744-4900

Compu-Das (Random Factors) S-100 A/D converter board

by rdd＠smart.net

While checking out the contents of some 8" floppies on my PDP-11/73, I spotted a couple of circuit boards sitting on top of my LA-120 (that reminds me, I've got to get another box of greenbar... hopefully Office Depot still stocks it; can you believe that I've had quite a few co-workers who had no idea what greenbar paper is?). One of these boards is an S-100 bus board, a Compu-Das model 696-33 made by Random Factors, Inc. of Durango, Colorado. The board is partially populated by chips (it came out of a repackaged Dynabyte 5200 system made by a company Computermotor Corp.), two of which are a Burr Brown ADC76KG A/D converter, and another Burr Brown chip: an SHC80KP (not sure what this one is), in addition to various TTL logic. What's interesting about this circuit board is that the chips are all socketed in little copper sockets made into the blue circuit board, and, apparently, to add D/A functionality to this board as well, one just plugs in some (or all?) of the missing chips. Does anyone know anything about this board? -- R. D. Davis rdd(a)perqlogic.com http://www.perqlogic.com/rdd 410-744-4900

I don't have any objection to that, in fact I'm inclined to agree, but I felt others don't want to take up more space than necessary. If encoded, I'd go for base64. It's the most efficient of the common schemes (hex, uuencoded, base64), has none of the ambiguities of uuencode (there are some very broken uu..code implementations around, because it's not fully specified), and if anyone does want to read it manually, a decoder is only a few lines of <language of choice>. On the other hand, hex has some advantages: easy to read, very easy to {en,de}code, and it would be more appropriate, perhaps, for binary values in tags (assuming the values weren't just written in ASCII in the first place). -- Pete Peter Turnbull Dept. of Computer Science University of York

New Find! Rolm 1602... Does anyone have any info/pointers/etc...?

by CordaAJ＠nswc.navy.mil

Hi! I just picked up a Rolm 1602 system at a local hamfest. It looks like an interesting toy (and a way to expand my horizons beyond the Sun/SGI/Dec arena. It even has a front panel interface :-) The unit seems to be in pretty decent shape (apparently it did not go through "Military" (i.e. sledgehammer) decommissioning, as the party I bought it from indicated that he obtained it from a NASA surplus auction). Unfortunately, there were no docs whatsoever with this critter. I seem to vaguely remember that some of the Rolm systems were just repackaged and beefed-up Data General Novas, but I could be wrong. Can anyone provide me with info/pointers/tech docs on this critter? I've done a web search and a dejanews search, but haven't had any luck. I even checked through some of the classiccmp archives, since I remembered seeing something on a Rolm system here a few months back, but I was unable to locate anything. Some of the things I'd like to know (or find pointers to): Hardware interface pinouts/docs: i.e. where do I connect an ASCII terminal... (There is no obvious serial connector, i.e. DB25, etc. All the connectors are some sort of mil-std twist-lock jobs) Does this critter have a disk interface of some sort, etc. Power requirements and pinouts: The previous owner had an AC line cord attached to a connector on the back, but I don't necessarily trust that he knew what he was doing. Is this really capable of running at 117V@60Hz, or did it need something oddball like 400Hz? Instruction set documentation: So I can play with the front panel :-) Software: i.e. Did this thing have a simple executive program of some sort? I downloaded Bob Supnik's Nova emulator in the hope that it might provide me with some hints as to Nova architecture, but there wasn't much documentation there. Will a Rolm 1602 run DG Nova code? If so, is there an archive of DG Nova software somewhere? The back of this critter uses a bunch of what looks like mil-std twist-lock connectors. Does anyone know an (affordable) source for these? I'm going to try pulling it apart tonight (It appears to be held together by about 17,000 screws :-). Any info would be greatly appreciated.... -Thanks in advance... -al- -acorda(a)geocities.com

Info on the Dynalogic Hyperion

by mgregory＠vantageresearch.com

Hi Leo, bad news, I'm afraid. When I went back to my local thrift shop on the weekend, the Hyperion that had been there for a few weeks was gone. I asked the clerk if she knew whether it had sold or been dumpstered, but she had no clue. A quick check of the dumpster didn't turn up anything either : v ( Still, I'll keep my eyes open. They do seem to turn up every now and again around here. They must have been popular with the oilpatch guys, who were on the road a lot. Regards, Mark Gregory

Nixdorf LK-3000

by doug＠blinkenlights.com

I'm trying to find some info about the LK-3000, an early hand-held "computer". I think it was made by Nixdorf around 1979, but it was also sold under other labels (I think I've got a "Lexicon" labeled instance someplace). Can anybody tell me what modules were available? Was there a module that made the thing user programmable, for example? Is anybody aware of a pre-1979 programable handheld? I suppose something like the HP-65 is a candidate, but an alpha-numeric keyboard and display would be more compelling. Assuming the LK-3000 isn't user programmable, would anybody take offense at somebody calling it the first PDA? (No, I'm not selling one on eBay. There is one for sale there now -- it's overpriced, though. These things aren't exactly rare.) Thanks, Doug

Racal/Blackbox BTS-100 term. server

by rdd＠smart.net

Greetings, Would any list members happen to be familiar with a terminal server sold by BlackBox that was oroginally manufactured by Racal-Datacomm, model No. BTS-100? A while back, I obtained one of these, but I can't seem to get it to work by connecting a terminal to the console port; I've tried data rates between 300 and 19,200, and nothing; also tried a few other ports. Something tells me that the best thing to do is reset the server to the default settings, but I'm not sure how to do this; no reset switch inside, but there is is a jumper inside that I'm going to try changing next. Any ideas for sources of documentation? The manufacturer and black box consider it ancient and can't help. Also, is anyone her familiar with the apparently not-so-rare defect in Emulex Performance 4000 terminal servers that causes a short circuit? I'm told by Emulex that they have an idea what the problem is, as a certain something is known to go bad in these units, but they refuse to tell me as I'm not an authorized repair center. Short of unsoldering surface mount ICs, I've disconnected and removed everything that I can find to disconnect and remove, and the short on the circuit board remains. The PSU seems ok when I apply other loads to it. -- R. D. Davis rdd(a)perqlogic.com http://www.perqlogic.com/rdd 410-744-4900

Available FT: DEC PDP boards

by mrbill＠mrbill.net

(I first posted this a while back, and was talking with someone about a trade, but I havent heard from him in almost two weeks now... Dave,if you're still interested, please get in touch with me ASAP) I've got the following assortment of PDP-11 boards and CPUs that have been sitting around for a few months; I'd like to see them go to a good home.

Maybe this just shows that I'm too much of a crypto geek, but anyway: "Shannon text" means that the letters are distributed in a way typical for English-language plain text. i.e. the typical ETAOIN... distribution. Depending on the context, it may also imply a "typical" distribution of word lengths too. This actually matters for chain printers (where you can choose a subset of letters that go on the print chain and get better performance), but it's not such a big deal for dot-matrix or laser printers which tend to print at the same speed (until something overheats, at least) no matter what. -- 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

Programming DEC LQP02/LQP03 printers

Could anyone help me out by looking up some programming information for a DEC LQP02 or LQP03, please? I'm working from an LN03 manual that happens to mention that the following control sequences exist on letter-quality printers, but it doesn't give details. I'd like to know how to invoke: DECFIL (Right Justification) DECFPP (Positioning) DECPSPP (Print Specified Printwheel Position) DECPTS (Printwheel Table Select) DECSS (Set Space Size) DECUND (Programmable Underline Character) While I'm on the subject, I see that the Terminals and Printers Handbook 1983-84 entry for the LQP02 says that it prints "32 char/s (letter-quality, Shannon text)". Does "Shannon text" mean anything to anyone? Cheers, Paul

No, you need a 871A power distribution or similar. Lacking that a box with a small DC power, relay and outlets will do as those connectors are simply switches on the BA11 (verify with meter). That why ba-11 has a switch on the front and also on the back. Allison

Maybe this is just a sign of how much I mess with computers/don't clean my car, but I've been known to discover 9-track tapes that slid down there in transport a long time back under my seat... Not to mention that there are assorted IBM System/36 parts under my passenger seat as we speak... The last time I cleaned my car, I found an Apollo Pascal manual I didn't even know I owned, heh..

ASCII Art Golden Gate Bridge & Plane

by mfhoneycutt＠earthlink.net

John, I would really like a copy of any ASCII art files you might have, especially if they are the ones with the embedded overstrike control codes for a Dataproducts band printer. We used to have some files for our Wang system that used a DP printer.. they were really great. They went out the door when the systems were retired about 12 years ago. I now have a MicroVAX II and the DEC version of the B200 DP band printer, so I should be able to run off some good copies on greenbar paper (back side, of course) of any files I can locate. This has been an interest of mine back to the early 70's when a few punch card decks would get passed around that you could run on the IBM that would generate some pretty fair posters for dorm room walls.

Looking for Cap'n Crunch 2600Hz whistle

> I'm also looking > for the October 1971 issue of Esquire magazine that featured the article > with John Draper talking about the "blue box". I know it said email directly but this topic is a little too interesting to do that with. The article mentioned is in Esquire, October 1971. It can be viewed at http://www.webcrunchers.com/crunch/esq-art.html John D. was recently featured in the New York Times: 26-March-2000 which was a near full page covering none other than the Homebrew Computer Club's 25th anniversary. Immensely on-topic, I believe! The books "Digital Deli" and "Hackers" are good references also. The former features an article on John D. written by Steve Wozniak. John A.

DEC power control? How do it know?

The system works >fine (thank you micronotes!) but I'd like to figure out how I could set it >up so that powering up the 11 powered up both the BA11 and the BA23. Now I >know the little 3 plug do-hickey (I think it is a mate-n-lock) normally >connects to a power sequencer in the rack, but I don't have one of those. >Is there any way to make it work otherwise? Am I correct, that you don't have a "Power Controller"? A DEC Power Controller is a metal box with one line cord in and many jacks for plugging in accessories, and a contactor (big relay) inside for switching many of the jacks on/off under remote control of the 3-pin plugs/cables. Without a Power Controller, you have no contactor, and no way of remotely switching things on and off. With such a small system, you can probably go to Radio Shack and get one of their power controllers, that works by sensing current draw to one of your boxes and turns the rest on when that one comes on. No, it's not as fancy or as configurable as a DEC power controller, and Radio Shack certainly doesn't have any versions that do 3-Phase at 60 Amps per phase, but it ought to work fine for a small system like yours. -- 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

Exabyte 8505XL tape drive or is it a DEC RZ24L

by ghldbrd＠ccp.com

Hello, Finally got a tape for this thing and it is DOA -- doesn't seem to do anything. The lower green LED on the tape drive flashes slow then fast. Interesting thing though -- when I interrogated the SCSI buss, it came back as a DEC RZ24L. thought you DEC fans might know what that is, and if it is a proprietary model that I can't use on my Amiga.

Looking for data sheet for Zilog 8530 Serial chip

It's not really friendly to the 68k buses. > > Allison I'm sure. It's in the Mac from day one, in Sun workstations since at least the Sun3 era (and still in one form or another in various sun4c boxes) and in every 68K-based product Software Results made after the Unibus products (the original boards used the COM5025 like the DEC DPV11? DUV11?) I will admit that it is not friendly to the MC68K bus. We used one or two dedicated PALs to handle the interfacing. Additionally, we had an 8Mhz CPU (10Mhz for the VAXBI model), but back when the Z8530 was new, 4Mhz parts were available and later some 6Mhz, but 8Mhz parts didn't come along until way later, long after our designs were done. There's lots of notes in the COMBOARD source code about not wacking on the Z8530 too fast. Eventually, we developed a kind of serial driver to handle swabbing registers, but the first products just used macros to always space out the time between telling the Z8530 which internal register to select and reading/writing that register. Personally, I think it's a cool chip, much cooler than the 8250/16450/16550 family. In addition to an async console for debugging, we pumped 3780, HASP and SNA traffic over them up to 128Kbps (our fastest modem eliminator speed). We only ever sold products for use at 56Kbps (64Kbps in Europe). -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.
