Hello, all: I am finally getting around to building the P112 Z180-based SBC from Dave Brooks (I got one of his last unpopulated boards). It has two 100-pin QFP chips (the Z180 and an SMC Super I/O chip), so, I bought the blade-like SMD soldering iron tip for my iron. So, here's the stupid question...how do I solder these things? Do I hold the iron parallel or perpendicular to the package leads? The board is pre-tinned, but I should I also tin the QFP leads? Any help appreciated. Rich

OT? Apple Stylewriter problems (PS progress)

>From: ard(a)p850ug1.demon.co.uk (Tony Duell) >Do these tap into the plastic of the case, or into brass inserts, or what? They go into pre-drilled cylindrical studs that extend from the back of the case (the side that doesn't plug into the wall) toward the front. There were matching cylindrical recess barrels from the front that extended toward the back and had holes in their circular bottoms large enough for the screw threads to pass through. Those barrels were what melted. >Are they machine screws, self-stripping screws (OK, self-tapping screws >:-))? If they're machine screws, they're likely to be metric sizes....

I think that's it. Why did I see a small voltage when I tested it *after* the fuse blew? The - side doesn't connect to *anything* - I'd think it'd float right up to the voltage of the positive side (charging through my VOM meter, if no other way). Or is there some effective resistance through the electrolytic? >Is there room to insert a normal fuseholder (maybe a 20mm one), then you >could use a fuse without pigtails... Hm. Maybe. I actually have a small fuseholder (one of the few parts I have in my box). I'll see whether I can make it fit. It would mount in among caps and diodes with not much room to spare on a small circuit board, though, so I may be stuck with a pigtail version. - Mark

Heh. That was my first guess too -- but I've never seen this particular thing used on a composite video signal before. (Well, maybe the L+sync used on b&w monitors...) My assumption will be (until I can check it out) that these are simply split off of the original apple RCA plug on the mainboard, and carry the same signal.

TSU05 Docs?

by Andreas.Freiherr＠Vishay.com

Does anybody out there have the docs available for the TSU05 controller board used in PDP-11s or VAXes with UNIBUS to connect to the DEC variant of the Cipher F880? The board is M7455, and I am looking for the meanings of the DIP switches. There must be CSR address and interrupt vector, each made up by several individual switches, but in addition to that, an "extended features" switch and one for "buffering". And, no, I am certain that I did not confuse this with the TSV05 (M7196) for Qbus. Thanks in advance! Andreas -- Andreas Freiherr Vishay Semiconductor GmbH, Heilbronn, Germany http://www.vishay.com

I need PDP-11/34A Help Again (Suprise Suprise)

by Andreas.Freiherr＠Vishay.com

Owen, still interested in getting your PDP-11/34 to work? - I am just about to reassemble mine after relocation. RUN light off and display 000002 means the processor halted at memory location 2, so it has probably executed a HALT instruction (opcode 000000) from location 0. Try this: enter 773000, load this address, and then press START. Since 773000 is the standard start address for a bootstrap ROM, this should get you a response on the console terminal attached to the DL-11W. (Don't remember which, but I think it should ask for a two-letter device code to boot.) BTW: The DL11-W has a 20mA interface as well as RS-232. (Note the "1488" and "1489" chips being present as well as a number of transistors and other discrete components.) Which on is used depends on the cable: the plug will have some wire connections to code it for either 20mA current loop or RS-232 / V.24. If you have an original cable with the usual DB-25 connector, it should be OK: current loop used a completely different 6-pin connector. For the settings at the terminal, I don't know this particular type, but with most DEC lines you should be best prepared if you use XON/XOFF handshake ("Main Rcv Hndsk" / "Main Xmt Hdsk"). Since at PDP-11 times, the 8th bit was commonly used as a parity bit, set your terminal to ignore this. Otherwise, you may get garbage characters instead of about every second readable character. A RS-232 break signal (certain voltage level applied for a certain time, not a sequence of bits!) can sometimes cause a PDP-11 to HALT (depending on settings on the interface board), so you may want to avoid this... (perhaps by choosing an appropriate setting for the "Disconnect" option for now?) So much from memory. If you need more details, let me know, and I'll dig into the docs. Good luck, Andreas -- Andreas Freiherr Vishay Semiconductor GmbH, Heilbronn, Germany http://www.vishay.com

Like it or not, it's hard to ignore and > it does make a statement. Demystify? I don't know, I expect my mother is as mystified about her spiffy new 2001 iMac as she is about her 1988 Mac Plus. She just expects me to understand, and hopes she can figure it out before she has to resort to calling me. On the other hand, it does simplify computers! 2001's iMac came with a sheet of setup instructions. Six numbered pictures, no words, and step 6 is pressing the power switch. It's real simple, just connect keyboard to computer, mouse to keyboard, phone or ethernet to computer, computer to power, and then press the power switch. No need to fuss with monitor or speakers, they're built-in. What was real fun about this upgrade was getting the files from the Mac Plus to the iMac. The Mac Plus can write 800KB stiffies, SCSI, and serial; and the iMac can read CD-ROM, USB, Ethernet, modem, and Firewire. Note what they have in common: nothing. I did a dry run using an iBook and my old Mac Plus. First I got a Belkin USB-to-SCSI doohickey and installed that on the iBook. Then I connected the Mac Plus' hard disk to the SCSI doohickey and booted MacOS 9.2. It asked me whether I wanted to initialize the unrecognized volume, and I told it no. So much for that idea, and a good thing it wasn't listening for spoken commands as I'd probably have turned its ears blue. The next try was with Basilisk II running on a Windows Me Harder notebook, emulating a Quadra 650 and running System 7.5.3. This worked better: I was able to connect the Plus' hard disk via an Adaptec SlimSCSI PCMCIA interface and mount it and copy the files over. Then I was able to use Appletalk to share the volume over the notebook's Ethernet interface and mount it from the iBook. So the WinMe notebook went back east with me. There I found that Mom's Mac Plus' hard disk is a Jasmine, and there's something about it that doesn't work with Basilisk II running System 7.5.3. If it's on the SCSI bus, the simulated Mac hangs when it tries to mount the disk. After three days of fussing with this I punted, used Stuffit on Mom's Mac Plus to make archives of all her stuff (all 8MB of it!) and Mac Kermit to transfer the archives over serial cabling to the simulated Mac. That took a couple of multiple-hour sessions so let's say a day. Then I unpacked the archives on the simulated Mac and did the Appletalk share so the iMac could copy the files over. And y'know what? AppleWorks 6.1.2 knows how to read ClarisWorks 1.0 files. One of my co-workers was the QA lead for ClarisWorks 1.0, and he is very happy to know not only that a little old lady in Maryland was using it for most of the last decade, but that her bits are safe. I'm very happy too. -Frank McConnell

Fate of the Astronautics ZS-1 systems

by auringer＠tds.net

Hello all, I had promised to post an update when the fate of the ZS-1 systems had been decided. Here it is. After negotiating with my company (Astronautics) for the release of the four remaining complete systems that sit at our Technology Center in Madison Wisconsin, we were able to secure one of the machines for the Rhode Island Computer Museum. The company is not the least bit interested in preserving the other three. They are destined to be scrapped. We tried. :( Merle Peirce will be in Madison this saturday, January 26th, to pick up the machine and _lots_ of spares for RICM. We will also be moving the DEC VAX 11/780 systems and other equipment at that time. If you are in the area and would like to lend a hand, please let me know. I am sure that we will be able to find a few souvenirs that will make it worthwhile. Merle plans to be at Astronautics around 9am saturday. Thankfully, the weather forecast calls for unseasonably warm temperatures this weekend (lower 40's). Again, please let me know if you plan to come. Thanks, Jon Jon Auringer auringer(a)tds.net P.S. To anyone who I may have failed to reply to personally, I apologize. The flood of e-mail that was generated by my posts about the ZS systems and the 11/780s was overwhelming. Between this, preparing to move our facility, and the possibility of pending unemployment, I have been having trouble keeping all of the balls in the air.

OT? Apple Stylewriter problems (PS progress)

by mtapley＠swri.edu

All, Potentially useful info for the list: 1) Stylewriter power supply uses zero-screws (or whatever you call them). 2) Stylewriter PS has a seperate fuse in the - leg of the output, and it's easy to desolder. The long version: Sat down with murder in my eye to work on the power supply. Pete Turnbull wrote (on another thread) >They look like a Torx screw head turned inside out. Imagine something >between a pan head and a round head (ie slightly domed) with six small >notches in the edge. The sides are sloping/curved and they're usually >hardened, and the edges of the notches are slightly rounded off so you >can't get a grip with pliers. There's a picture at >http://website.lineone.net/~dave.cushman/zeroscrew.jpg A perfect description of the three fasteners holding the case together - as I realized once I had them out in the light of day. Unfortunately I *got* them out in the light of day by trying to pop them loose after heating with a soldering iron. Instead of melting the studs the threads were threaded into, I melted the barrels of the recesses the screw heads were in. Things Got Smelly, the case creaked apart, and the recess barrels were left with the studs, screws still firmly in place. However, at that point, I was able to grab the severed barrels, squeeze with pliers until the walls of the barrel gripped the zero-screw head, and twist out the zero-screw. Anybody need 3 slightly used zero-screws? *I* sure as heck don't! To put back together, I plan to find longer pan-head screws with similar diameter and thread pitch, put around the studs plastic soda straws long enough to reach up to the other side of the case, then put the pan-head screws (with washers as needed) through the holes that originally formed the tops of the recessions and through the straws into the studs. (The soda straws are to electrically isolate the screws from whatever voltages are flying around inside, because the recess barrels ain't gonna do it, now being in pieces in my trash can (with extreme prejudice).) Inside, there's a big transformer. One side has 2 leads wired to the blades that go into the wall. The other side has 3 leads going to a circuit board. The leads on either end go through diodes to the "+" output. The lead in the center (marked "C.T" - let me guess - center tap?) goes through a cylindrical glass fuse to the "-" output. There's a big capacitor (electrolytic? Black cylinder) between "+" and "-" and a few small (ceramic?) disk capacators scattered around. The fuse had shuffled off its mortal coil. I mean, even *before* I desoldered it. Which, BTW and of course, I think I did without damaging anything. This thing is so simple even I can almost understand it. Now I need a 3.7 (? something like that) Amp fuse with pigtails, and a couple screws, and who knows, maybe I'll be back in power. Definitely going to be a web-shopping day. Comments, 'attaboys, "enough-already-with-the-d*mn-printer"'s, etc., all welcome. - Mark

(Ok so I didn't look too well.. :) I've cleaned it up, and it looks in good condition, with two exceptions: There is a pin broken off of the power cord :/ -- I'm going to replace it.

The Xerox 4050 is a printer controller, but appears to be some sort of mini-computer with a Xerox logo on it; it has a floppy drive and possibly internal hard drive. If anyone knows anything else about these, info posted to this list would be appreciated. The thing is waiting for pickup by a scrapper, whose truck is currently being repaired. If you get here first, you can have it. It's about the size and weight of a chest freezer. Also available is an IBM PS/2 Model 80-386 micro-channel tower machine. Includes a micro-channel token-ring network card. Both of these items were pulled from use in the last couple of months and should be in good working order. They are available _for_local_pickup_only_ in Lincoln, Nebraska. Drop me a note quick if you want either of them before they go to the big bit-bucket in the sky!

These computers are not rare artifacts to be hidden away behind glass walls, only to be touched by the neophites in white lab coats, you know. Go ahead and experiment, heck throw the completely wrong hardware in and cause a major short circuit! And in so doing, know that you can always get another apple ][+ or 3 for about $5 (if not for free, heaven knows i keep getting offered the things...) Cmon, what could possibly be less valuable than an Apple ][+? A C64 perhaps... >> just because they are plentiful in /some/ places doesnt mean you should just abuse them for fun.

by whdawson＠mlynk.com

To all (especially those that are desirous enough of the subject items to drive to Hackensack, NJ), As a participant in the Computer Rescue Squad, I received this email (edited): -> Osborne Executive and a Texas Instruments MicroLaser Plus -> free to good home. Must pick up, I do not have time to ship. -> Thanks. -> Paul. -> Ph.D. I answered with a brief reply indicating that I cannot do so but surely can locate someone who can. Paul's reply to this was: -> A couple of other "Computer Rescuers" have contacted me but the logistics -> are awkward. Do you know anyone who can just stop by the house here and -> pick up some evening? -> Thanks. -> Paul. -> Ph.D. I have Paul's email address and telephone number. If you can meet the requirements of Paul's reply (i.e. 1. STOP BY HOUSE, 2. PICK UP (HACKENSACK, NJ AREA)) please contact me off-list and I will forward his contact details to you. Sorry, but because of the SPAM issues relating to email addresses on this list the last thing I want to do is post someone else's email address here without their permission. 'til later, Bill w1h0d1a0w1s0o1n(a)m0l1y0n1k.com (my valid email address does not contain any binary digits, to those of you who cannot access it in the header of this posting) http://www.swtpc.com

First, its Hackettstown, not Hackensack (at least that is where he told ME he was... if it was Hackensack, I would have picked it up the night he emailed me, being that Hackensack is 15 minutes from me... Hackettstown is 60 minutes) Second: I already told Paul I would be happy to pick it up. Then he offered to drop it off at my place when he went to CT on Friday. I told him that would be fine, but not to make a special trip (I can't figure a way to get to me that is a route to CT without taking a good 30 minute detour). I guess I will re-email him, and clairfy that I am happy to drive to him to pick it up. -chris <http://www.mythtech.net>

Apple II boards

by csmith＠amdocs.com

Hi everybody, I have three more Apple questions Given that I'm going to be repairing that Apple II Plus soon, I find myself wondering what is the maximum amount of ram that the machine can address? I also wonder whether it would be remotely possible to "upgrade" it with the old IIGS memory board that I swapped out of my GS a while back ;) (Probably no such luck there...) Last, but not least, what are some recommended boards/peripherals for the Apple II Plus? What about the IIe? (Yep, got one of those too -- I'm sure this one really _is_ a IIe, and I'd be especially interested in knowing about the IIGS upgrade) What about the IIGS? Regards, Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

Bell & Howell Apple II update

by mythtech＠Mac.com

>Heh. That was my first guess too -- but I've never seen this particular >thing used on a composite video signal before. (Well, maybe the L+sync >used on b&w monitors...) I have a couple of JVC monitors with BNC composite video connectors. These are the monitors salvaged from a video editing suite... I actually saw BNC used for composite video on a fairly regular basis in the TV studios (I think I saw that more often then seeing RCA connectors) >My assumption will be (until I can check it out) that these are simply >split off of the original apple RCA plug on the mainboard, and carry the >same signal. (I hope this is the case, since it would be a simple matter >of fabricating an adaptor (for which I may have the parts...). You can buy a BNC to RCA adaptor from places like Radio Shack (or even a BNC to RCA cable... although I am not sure Rat Shack stocks those anymore... might be special order). Or, like you say, it is fairly trivial to build a custom BNC to RCA cable. -chris <http://www.mythtech.net>

Bell & Howell Apple II update

by mythtech＠Mac.com

>(When somebody trips over the cord, it should be strong >enough to pull the entire machine off of the table.) I always loved this logic. Lets build the cable really strong, so that when someone trips on it... we save the $15 cable, but yank the $5000 computer onto the floor breaking it instead. Although, I also understand the flip side... it isn't that the cable is designed to withstand abuse, so much as designed to not fall out easily during standard use (thus rational why all the electric cords for my fire trucks use twist lock... even if it means it will knock over a $3000 light tower rather than unplug itself... the last thing you need at an emergency scene is cords randomly unplugging themselves... and the last thing a school tech person wants to deal with is 100 calls a week because the RCA plug fell out again, and the untrained teachers don't know enough to plug it back in... and things like BNC are used on pro level AV equipment for the same reason, so cables aren't always falling out when something is shifted around) -chris <http://www.mythtech.net>

Bell & Howell Apple II update

by Lee.Davison＠merlincommunications.com

..... there was a connector for the overhead video monitors. It was an unusual connector, with a hollow cylindrical plug a few inches long, with a pin in the center. That sounds like a MUSA connector, common in broadcasting but not in domestic equipment.

The //e takes the same cards, except that it already has 64K RAM and has no need of a language card; it also has provision for a special 80-column card in Slot 3, set back from the rest of the slots. -- Pete Peter Turnbull Network Manager University of York

'Cos they're usually hardened and a dental burr will make little or no impression on it. A cutting disk works, though, when there's room to get at the screw head. It's easier to buy the right tool bit, though. And they're usually so tight that epoxy will give way before you turn it. -- Pete Peter Turnbull Network Manager University of York

The SMP support in NetBSD is still pretty new, and still lives in an "experimental" CVS branch. While the latest snapshot kernel seems pretty reliable (./build.sh -j 2 works at least twice in a row :-), it's probably not a good thing for production use just yet. YMMV. Other than that, NetBSD is awfully useful. Ken

Resolved? HP 9000 800/G40 console cable

by csmith＠amdocs.com

I've found what I _think_ is the proper cable for this machine. These bits of info were buried somewhere in the HP web site. I unfortunately don't have the attributions (you can find them right now with a google search), but the general idea is: ------------------- The HP part number for the cable is A1703-63003 and the price is $43 US dollars. This info was found at http://outfield.external.hp.com/cgi-bin/spi/main.pl which is the home page for HP partsurfer, an application that allows toy to identify and order parts for many HP machines. -------------------- Pinout for standard console _cable_ (A1703-63003) is: DIN CONNECTOR FRONT VIEW DIN 25pin 2__1 3.____.2 4____3 6||5 4.____.3 ^ | 1.____.7 KEY --------------------- These were both posted in reply to a question about a different machine -- "F" class I think -- but I have checked HP's "partsurfer" site, and the cable is, indeed, used on the "G" class as well. I have contacted two resellers to see whether I can get it at a reasonable (read: not $46) price. Otherwise I will try to build it.
