They are the ones that takes the longest to run, the others complete mostly in less than a second. You have to know the layout of your backplane to know where grant contnuity cards are required. Old uVax II backplanes have the memory bus on the CD rows for 2 or 4 slots, and need no grant continuity there, but the AB rows are Q-bus, and would need either double-wide Q-bus boards there or grant continuity. Later backplanes didn't have the Q-bus start until after the first couple slots. So, you really need to know what the backplane layout is. Jon

amusing google image search results

by barythrin＠gmail.com

Yeah. It was a cool idea at first but I've mostly stopped trying to use images as a relevant computer search. I'm not sure why it always seems to pull up random peoples pictures or some underdressed women instead of the computer. Unrelated but also interesting (if it works) was the search the web for a matching photo. Sorta neat sometimes with auctions or forum/craigslist posts prior to a sale. ------Original Message------ From: David Griffith Sender: cctalk-bounces at classiccmp.org To: cctalk at classiccmp.org ReplyTo: General Discussion: On-Topic and Off-Topic Posts Subject: amusing google image search results Sent: Oct 26, 2012 1:11 PM I noticed that doing a google image search on the string {kaypro 2/84} yields an interesting array of pictures that have nothing to do with Kaypro.

Microvax II won't boot, hardware error?

by tpresence＠hotmail.com

I have been trying to get a microvax II fully functional over the last few weeks and I seem to have a roadblock. The system used to boot and allow logins, but now after connecting a VCB-02 cable to display, keyboard and mouse, it has become more and more unreliable. It may be possible that some assistance I got from a colleague might have helped to cause this situation, but I think its unlikely. When the system was booting properly, it wouldn't bring up decwindows even when the display, kb, and mouse were attached to the bulkhead cable (bc18z). I was asked to check the WINDOW_SYSTEM variable within sysgen to determine if the current value was anything other than 1. In this case it was 2. He asked me to change the value to 1, and then to write it to current and active, then complete an autoconfigure all. I don't feel this is a factor, because when I boot into conversational mode and set the WINDOW_SYSTEM variable to 0 the system still faults when I perform a @sys$system:startup. In conversational mode, when I launch the startup.com script, the kernel panics as it does when it boots in normal mode. I was hoping to edit the startup.com script (or move it to a safe location and place a partial startup script in its place), but I'm not sure what parts I need to have. If I dont run the startup script, I can't run anal/crash because of protection issues. At first when connected to a display the system would kernel panic during boot. It would boot WITHOUT the display being connected, however, so I continued using it without the display. Unfortunately, now it appears to panic every boot, and I can't get to a prompt to run any diagnostics such as anal/crash. No user based changes were made to the system between boots. The real brain teaser is that it doesn't always crash during the same process load, I have been trying to get a microvax II fully functional over the last few weeks and I seem to have a roadblock. The system used to boot and allow logins, but now after connecting a VCB-02 cable to display, keyboard and mouse, it has become more and more unreliable. The real brain teaser is that it doesn't always crash during the same process load, sometimes its OPCOM, sometimes its STARTUP, sometimes its DECW$STARTUP as it is below. Anyone have any insight on how to proceed? I'm not a very experienced user. A crash example is below: KA630-A.V1.3 Performing normal system tests. 7..6..5..4..3.. Tests completed. >>> boot 2..1..0..

C.B. Falconer 1931-2012

by dgriffi＠cs.csubak.edu

Reposted from comp.os.cpm by Charles Richmond I am sorry to report that C.B. "Chuck" Falconer has passed away. He used to be a regular in alt.folklore.computers, comp.os.cpm, and comp.lang.c. He had a long and involved history with computers and programming. He was born in Switzerland on September 13, 1931 and passed away in Damariscotta, Maine on June 4, 2012. I'm sure most everyone here remembers him and his posts to Usenet. One of his many accomplishments was writing an article for an early Dr. Dobbs magazine on implementing floating point on the Intel 8080 microprocessor. His resent resume and the downloadable files from a recent web page of his... can be found at You can a recent resume of his at the ClassicCmp website: http://tinyurl.com/8fudn4o His obituary is at: http://tinyurl.com/8ahongj -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

Epson QX-10 question

by fjkraan＠xs4all.nl

> you put in a disk, you get a cursor, but that`s it. Puter won`t give > disk back. Do I have to take it apart? The SD-321 drives have a lock mechanism that should release the disk when the button is in the 'out' position. But it doesn't as the old grease keeps the lock in place. I have observed this with both the QX10 and the TF-20 which both use the 1/3 height SD-321 disk drives. So far I managed to get my disks back by prying the lock upwards (or was it downwards?) with my fingers (not very pleasant work). Everytime I plan to fix the drive by replacing the gunked grease, but so far it didn't happen. Greetings & success, Fred Jan

QBUS/UNIBUS transceivers (again)

by fraveydank＠gmail.com

Hey all, Since I'm stuck in a hotel for the IEEE LCN conference, I had nothing better to do than look up lots and lots of datasheets in search for an ideal driver/receiver pair for modern DEC bus circuits. Warning: below is a lengthy missive. Ignore it if the subject line doesn't turn you on (so to speak). The driver is generally the easy part; there are quite a few FETs out there that ought to do the job acceptably. You need a total (driver + receiver) capacitance of 9.35 pf, which is generally the tallest order, but it's easy enough to limit the slew rate of the pulldown by putting a series resistor in line with the gate. I believe Peter Wallace recommended the FDV301N, which seems as good as any; put one for the driver and one at the source as a gate for a group of them, and you should have a pretty effective transceiver. It might take a bit of space, and you'll eat a lot in assembly if you're not doing it yourself, but as Dave McGuire pointed out, if your main logic is contained in a micro and/or CPLD/FPGA, you're going to have plenty of space. And for SOT-23 packages, you can probably get close enough to the density of the original (quad-gate) DIP devices. The FDV301N claims a Coss of 6 pf, though I haven't done my homework to think about how the other parasitics affect the input capacitance. The receiver is a little harder. In the National (now re-branded by TI, which is hilarious considering the part was obsolete and long out of production by the time TI acquired them) app note on the DS3662, they indicate that they essentially just did the obvious thing and used a comparator for the input. Doing so with discrete comparators is possible, but generally costly in terms of both money and board space, and I've found parametric searches of comparators to be a bit tricky, depending on where you look. At least looking through what Digi-Key offers (and they're pretty much the best parametric search I know), there are few quad units fast enough which don't break the bank. The MAX9108 is a good candidate, though (quad gate for $4, or $2 in quantity 100, which you'd certainly be looking at for more than one or two units). It's a TSSOP-14 package, which isn't exactly tiny, but it's smaller than a DIP in most respects. It has a dual-element cousin, the MAX9107, which comes in a SOT23-8 package; I believe you could achieve higher density that way, though you'd end up spending more per gate. The input bias current is in the sub-uA range, but there's no input capacitance listed, which bothers me a bit. The outputs are TTL-compatible, which is generally compatible with 3.3v logic as well; it has a typical Voh of slightly more than 3.3v, but at 100uA source current, which is well within the handling range of the built- in protection diodes of most FPGAs (and it's close enough that it probably wouldn't trip them). Another good candidate is the NE521, which has some very nice logical gating inputs (which would save some external components if you're using bidirectional lines on the FPGA side). It's also a dual part, but unfortunately only available as small as SOIC-14, which doesn't provide for a lot of density (it is available in DIP, though, which should make some people happy). Its propagation delay is 12 ns instead of the MAX910x's 25, though both are still comfortably below the 32 required for DEC buses. Bias current is a max of 40 uA over temperature range (DEC max for the receiver unit load is 80 uA). It also does not provide an input capacitance; I suppose it's common with comparators? This one is also not as cheap per gate; even in quantity 100, it's still almost $4 each ($2 per gate), which probably offsets the convenience of having the enables built in to the part for most people (especially considering the larger package size). In any case, the solution doesn't seem as infeasible as I previously thought. Anyone want to go in on a few test boards together to split the costs? It seems like it would be prudent to make a few short (2 inches, maybe) dual-width boards to test input and output capacitance/waveforms before we try making whole boards, and if someone has a UNIBUS machine they're willing (and able) to test out on, that would be handy since I definitely do not. Also, are there major flaws in the above analysis? Am I totally smoking crack? The app note I referenced is here: http://www.ti.com/lit/an/snla139/snla139.pdf There's another interesting related one here: http://www.ti.com/lit/an/snla134/snla134.pdf - Dave

An 80386 CPU S-100 Board

by monahan＠vitasoft.org

In case you missed it on one of the web postings I would like to mention that Andrew Lynch and I have just completed a prototype of a new 80386 Master/Slave CPU S-100 bus board. This exciting board is capable of reaching up to12MHz in an S-100 system with an active terminated bus. This is an ongoing project. It utilizes the 16 bit mode of the 80386 to address the 16MG of RAM the S-100 bus is capable of addressing. A second daughter board system with an overhead ribbon cable connector is planned to for daughter board(s) to enlarge the RAM space up to the 4GB the CPU is capable of addressing (using high density static and DRAM chips). If you would like to read about this board please look here:- http://s100computers.com/My%20System%20Pages/80386%20Board/80386%20CPU%20Boa rd.htm It is too early to accept "orders" for this board, but if you would like to be kept in the loop as this board evolves keep an eye on the above page.

PERQ monitor problem (was HP 9845 power supply diagnostics)

by colineby＠isallthat.com

My recollection is it was both rolling and skewed. I need to get it in the queue for our CRT doctor to look at. He's got a never ending stream of Cubs to deal with supporting our BBC classroom systems. I have to nudge the PERQs monitor in among them, as well as an HP 2645 scan card that's puzzling me. I may have mentioned (?) I took the expedient measure of swapping the base from one monitor for the other to address the cable sheathing issue we had. This leave us the backup monitor on the injured list waiting for the doc. --Colin ard at p850ug1.demon.co.uk wrote: >> >> Tony and Rik, >> >> Can you guys just sanity check something?

fine pitch soldering

I do stuff as fine as 0.4mm lead pitch, which is a bit of a pain. The bulk of stuff I now make with a pick and place machine and a reflow oven (converted toaster oven with thermocouple ramp-and-soak controller). But, I still do a lot of prototypes and rework by hand. The MOST important thing is a stereo zoom microscope with a long working distance. A working distance of 2-3" is necessary to get your hands and a soldering iron under it. A ring light can be made from a ring of PC board material that fits around the snout of the microscope. Carve a ring in the copper of the PCB so it becomes two concentric rings. Use a 12 V DC wall-wart power supply and 8 while LEDs, with about 1 K Ohm series resistors. Make a piece of cardboard with a 1/2" hole in it, use this as a mask to isolate the light from one LED at a time and bend the LEDs so they all converge about where the viewing area is. This mask is for alignment only, store it somewhere as you will occasionally bump the LEDs and have to realign them. Solder braid can be used to remove excess solder bridging the leads, which WILL happen frequently. For big, high-density chips, this is my procedure: First, put a tiny dab of solder on 2 corner pads. Align the chip with the pads, and solder the corners that have the extra solder. Now, use a piece of solid wire to apply GC brand (or equivalent) liquid flux across the leads. Just dip the end of the wire into the bottle and then wipe it across the leads. If the board has enough solder plating, you may not need to add any solder, just use the iron to reflow the pad solder onto the leads. I generally add a little speck of solder every 4th or 5th lead as I go down the rows. I use .015" solder, the thinnest I seem to be able to get nowadays. You used to be able to get .010" fairly easily. I've probably done about a thousand of these now using this technique. It is probably best to wash off the flux residue later with solvent. Jon

VMS newbie with sick VAXstation

by spectre＠floodgap.com

So I finally got the needed MMJ serial cables and got my VAXstation 3100 setup using the Solbourne S3000 as a serial console. The boot monitor comes up just fine in cu, but the machine remains at the boot monitor and does not start VMS. TEST 50 says ?41 DEVASSIGN, TEST A SHOW DEV shows an ESA0, which I assume is the 10b2 Ethernet because it shows a MAC address, and a DKA0, which is a 1.05GB drive. So, I do BOOT DKA0 and it appears to start (transcribed from my Android, sorry for typos): %SYSBOOT-I-SYSBOOT Mapping the SYSDUMP.DMP on the System Disk %SYSBOOT-I-SYSBOOT SYSDUMP.DMP on System Disk successfully mapped %SYSBOOT-I-SYSBOOT Mapping PAGEFILE.SYS on the System Disk %SYSBOOT-I-SYSBOOT SAVEDUMP parameter not set to protect the PAGEFILE.SYS OpenVMS (TM) VAX Version V7.2 Major version id = 1 Minor versio [cut] %DECnet-I-LOADED, network base image loaded, version = 05.0D.00 %DECnet-W-NOOPEN, could not open SYS$SYSROOT:[SYSEXE]NET$CONFIG.DAT **** Fatal BUG CHECK, version = V7.2 KRNLSTAKNV, Kernal stack [cut] (system dump follows, I can type this in if you want it) Being a total novice to VMS system administration, what should I be looking at? -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- MOVIE IDEA: The E-mail Signature Who Loved Me ------------------------------

Superbrain schematics

by adwallach＠gmail.com

Hi Andrew. I have a SuperBrain QD that I had up in the loft. Unfortunately the display no longer works as the graphite core that fits into a donut coil attached to the side of the Video case has snapped in two places. Though the display appears to work no characters are visible. It does boot and if the dir command is entered it is apparent that it is attempting to display the output as the cursor moves across and down the screen. I have tried looking for spares via Google but no luck. Hopefully knowing what the gizmo should do I could fix or replace it. Thus if you have still have the schematic package available in digital or hard copy, I would be grateful if you could let me know. I am retired and wrote business applications in the 1981's and am curious to revisit them to see how things have changed since the heady days of CPM 2.2. I realise that your post goes back to 1998 but it would be great to receive a reply. Regards Anthony

I'll have to take a look at it and see if there is a part number on it. -Glen The /76 has dual SCSI busses, so the presence or absence of the external terminator is not critical for proper operation of the internal devices, provided that the internal bus line is properly terminated. Another vote in favor of hacking in a CD-ROM drive and booting from the disks. Unfortunately, VAX-VMS doesn't have the "Minnie-VMS" environment that Alpha does.

Removing mineral deposits from circuitboards

by derschjo＠gmail.com

So, here's a fun one: See the picture(s) here: http://yahozna.dyndns.org/scratch/gridcase/ This is in a Gridcase 3+ I picked up last week off eBay for what seemed at the time to be a pretty great price. Heard some stuff rattling around inside so I opened it up before doing anything else and what I seem to have is a few large mineral deposits on the main circuit board. It's pretty well localized,and aside from a completely dissolved drive support post and a few rusted screws there really isn't all that much rust(amazingly). And thankfully the corrosion that's present has almost entirely avoided any custom ASICs or other parts on board. Everything else in the system aside from the bad patches in the pictures is clean (although the whole thing smells like a dank basement, geeI wonder why) and the underside is almost corrosion free so there's a non-zero chance I could get this running again. Except I have no idea how to go about removing the buildup of... crud... on this thing. It's pretty solid, I've soaked it for a few minutes in water and chiseled at it (gently) with the tip of an xacto knife and I got some of it off that way but it's very slow goingand I'm afraid of removing what's left of whatever's underneath it before I can identify it. Any tips for removing this stuff? (Also, as an aside -- my mails to this list are clearly making it to the list, but I never see my own posts/responses anymore... any ideas?) Thanks, Josh

Interesting ePay find...

by jon＠jonworld.com

I was browsing on e-bay and found these TI-1500 systems. I have no link to the seller. I never heard of these before. http://www.ebay.com/itm/TI-1500-unix-computers-/251167418839 After a lot of Google I found this: http://www.?home.?unix-?ag.?org/?engel/?ti/?

HP 9845 power supply diagnostics

by colineby＠isallthat.com

Josh, My apologies! I got tangled up with other things and dropped the ball. Do nag me if I seem to go away. Software -- I'm afraid the PERQ software is in the end of the archive they are still cataloguing. So I tried my luck a bit. I came across a games disk which appeared to have a copy of an asteroid clone on it, but the disk didn't appear to be readable. I've imaged it, but the system threw every kind of data error when attempting to read it. Attempting to execute the file I *did* managed to extract hung the PERQ up good and proper. I'm reasonably confident the drive is reading well and this is genuinely a diskette issue. I've also imaged a set of POS based utilities, but all those disks appeared quite badly damaged (one of them was actually clear in sections). I don't think much will come from a forensic examination of the raw image. But by happenstance, we have two copies of that set, and I've not tried the second set yet (about 8 diskettes). Depending on cirqs this weekend I might get an hour or two to slave over a hot PERQ backing off files and validating media. Nag me again Sunday, if I fail to report back! --Colin Josh Dersch <derschjo at gmail.com> wrote: >On Mon, Oct 22, 2012 at 11:43 PM, Colin Eby <colineby at isallthat.com> wrote: > >> >> >> BTW Tony, thanks again for your advice on the PERQ.

Skipware level, late 2012

I just collected a new PC carcase this morning which was advertised on my local Freegle group (i.e., Freecycle by another name) last night. Intel Core 2 Duo Extreme 6850, 3GHz, 8GB DDR2 RAM.

Is there an easy way to use the SCSI > port on the VAXstation 3100 (I hear it has a different pinout)? Are you assuming the hardware is operating properly? I went through this a while back with one of my VAX Station 3520s. I could sometimes boot to a usable point, but then crash - normally, it wouldn't make it that far. I put a known good drive in and attempted to load a new version of VMS. It would get partially through and then crash. Turned out that a +5 volt supply had nearly 0.5 V of ripple. Changing a few caps in the power supply fixed things up... ->CRC

Couldn't this be a symptom of a redefined SYS$SYSROOT: pointing somewhere else other than DKA0: (such as an external expansion pack)? In any case, if your VS isn't running a new version of UCX or MultiNet/TCPware go ahead and get TCPware or Multinet, as the version of UCX that came with 7.2 would bring the machine to a crawl under light network load.

unibus to modern disk interface? (tangent on MFM drives)

by js＠cimmeri.com

Subject: Re: unibus to modern disk interface? From: allison <ajp166 at verizon.net> Date: Mon, 15 Oct 2012 21:17:57 -0400 ... Me I planed ahead and kept all the small drives that people didn't want but still ran from older MFM and IDE to SCSI. That and old boards even if flagged dead.. they can be fixed or used for parts. Allison Hey, A. How are you keeping the bearings in your MFM drives lubed (if you are)? Most of my MFM drives still work, but the bearings are drying out. As the motors work harder to turn, the motor controllers run hotter and will burn out there first unless a way can be found to apply lube to the motors. Lou Ernst and I have been mulling over this issue. - John S.

Prestel and Viewdata

by robert＠irrelevant.com

In a random fit of rash behaviour, I've copied over and "made live" the wiki version of my viewdata history/preservation/memories website, running alongside and in parallel to the existing version. This means that if any of you want to contribute, then rather than hoping I'll get around to adding stuff at some indeterminate future date, you can pile right in there! There's still lots of pages to convert over, and I need to sort out my custom plugins that manage the documents and viewdata pages themselves, but that's why the old version is still there... at least this way, I might feel guilty about not having updated for over a year and get on and do it ... So, if anybody wants to help, get in there! (Wiki) http://www.viewdata.org.uk/introduction (old) http://www.viewdata.org.uk/index.php?cat=10_Home&page=10_Welcome Rob.

S: AS/400 connection software for classic Apple Macintosh

by poc＠pocnet.net

Hello, I'm searching for certain software to make AS/400 and Classic Macs (late System 6 to 7.6.1) "talk" together properly. It's no problem to get this with current OS X but the old software has gone and I can't find this, let's call it abandonware, on the net. I'm running an 9401/170 attached to a token ring where also a Mac IIfx with a TokenRing NB 4/16-Board is attached. Plus a PowerMac 7500, also with a Token Ring Board. The whole stuff is running very smooothly but I'm lacking direct access to SNA and/or tn5250 via TCP/IP. According to an old Apple Book (Data communications and networks) there have been many solutions available (in no particular order): - Incarnations of sna?ps 5250 (gateway and client), - MacRUMBA Gateway (I got hold on the client a few months ago), - TokenAxcess, - MacMainframe (gateway and workstation), - asc5250 (Comm Toolbox module collection for TCP/IP), - MacMidrange, - Possibly MacIRMA (gateway and workstation), - MacTwin (with Twinax Card! Without it's nearly useless). - Netware for SAA 3.x, since I'm running NW 3.12 in a virtual machine. Any of these are of interest. A big plus (but not a must-have) would be if the particular software is complete with original disks, manual(s), and package. I also heard of a PTF for the AS/400 which provides AppleTalk service to the machine. Users can then connect to the AS/400 via Mac RUMBA, sna.ps client or such. One source of information said, this was a looong time ago and that PTF is expected to apply to OS/400 V3 or older, while I'm running V4R5. More specific information on this topic would be very welcome! Can't find anything useful on the net for that. Thank you in advance for your time and help. Regards, PoC

Kickstarter project for a new run of P112 kits

by dgriffi＠cs.csubak.edu

Since I ran out of P112 kits last year, I've been asked multiple times to produce more. The critical thing in doing this is financing the project. So, I've set up a Kickstarter.com project to get things going. There are some differences in the kits this time round. The big one is that I'm no longer offering complete kits. Sorting thousands of tiny parts into ziplock bags was a big hassle. Instead the kit will contain a PCB with surface-mount parts soldered on, a boot ROM, serial port pigtails, and two CDs of documentation and software. I have prepared a shared project on Mouser for most of the remaining parts. The serial chips are obtained >from Digikey.

socketed 84-pin PLCC logic analyzer connection

by keithvz＠verizon.net

I've got the need to connect a logic analyzer to a socketed 84-pin PLCC IC. The test clips I'm familiar with won't attach properly because they expect a soldered chip instead. Besides removing the socket and resoldering the IC directly to the PCB and using a traditional test clip (which are affordable), are there any other plug-and-play solutions? I've found these http://www.emulation.com/catalog/off-the-shelf_solutions/logic_analyzer-sco… http://www.emulation.com/cgi-cfm/insert_quantity.cfm?part_number=BC4-84-PCC… ($308) and http://www.logicalsys.com/painfo-vpasp-vb.asp?adapter=pa84-pp ($185 US) which seem pretty darn cool, but also pretty darn expensive. The PCB is almost 30 years old, for whatever that's worth. Thanks, Keith

Quadra 700 buttons?

by fraveydank＠gmail.com

Hey folks, I recently brought a Quadra 700 back to life that I got non-working for a decent price off eBay. The resuscitation is an exciting story in and of itself: - First, the power supply was dead, which I traced to a bad transformer for the +5v trickle supply, which also operates the rest of the power supply's electronics; not being able to repair it or determine the winding ratio for a replacement, I had to get another power supply for more than I paid for the machine itself. If I ever find out the details of the transformer, I may resurrect the supply as a spare; the folks formerly of Bomarc have reverse-engineered schematics that I may avail myself of. - The PRAM battery had exploded, causing untold amounts of damage to everything beneath it. One SIMM was rendered non-functional, the interrupt and reset buttons are completely useless (they alternate between inoperable and intermittently on, neither of which is useful) and the acid ate away pin 14 (the power leg) of a 74F04 as well as the pad beneath it, which made for infuriatingly erratic behavior until I figured it out and fixed it with a white wire. Anyway, I have a very happy machine now, but I need to replace a few components. I've found a perfect replacement for the battery holder (which was eaten away by the acid, as I discussed in a previous email), but I'm having a hard time finding replacements for the right-angle buttons used for the reset and interrupt buttons. They're not strictly necessary, but since I plan on using the machine for NetBSD driver development among other things, they'd be very nice to have. So does anyone happen to know where to find the BOM for the Q700 (highly unlikely), know what kind of buttons were used for the Q700 (also probably the IIci and IIcx, somewhat less unlikely), or know a good way to find buttons with precise mechanical dimensions? I'd be greatly indebted. I realize this is a long shot, but if there's anywhere that might have it, it would be here (also Erik's VCF, which I'll also check). - Dave

System for sale on Epay, Listed as Northstar Horizon is actually Ferguson board

by jws＠jwsss.com

This is an auction for a system on Ebay which might be interesting. It is listed as a "Northstar Horizon" but has what appears to be a single board system marked Ferguson. That would probably not be from Northstar. Also it is built up with 8" floppies which is even less related to Northstar. it appears he got a pile for a Northstar system with the Ferguson homebuilt which is in an Incoterm box which holds the floppies. There is a listing for a bigboard on bitsavers which is probably for this system. http://www.ebay.com/itm/400301360595 Price may actually be something if anyone feels a burning need for a Ferguson board, but I think its high for an ordinary Horizon. Too bad there is a missing Horizon.

I'm looking to move in that direction. I got a VERY good deal on a Philips CSM-84. This model can hold up to about 55 8-mm feeders (capacity reduced for larger sizes) and has a vibratory feeder option and a large chip alignment station. For small chips and passives it aligns with mechanical jaws on the head. it has 3 heads, I have 2 set up with the jaws and one with no jaws to use the separate aligner. These machines are also available with vision, mine does not have that feature. It is a BIG machine, 5 x 7 feet, and needs compressed air and a fair amount of power. it is single-phase, however. It weighs about 1600 Lbs. Note that with all these machines, the feeders will probably cost more than the used machine. The CSM-84 is a VERY flexible machine, and easy to program. (The vision system needs a LOT more programming than the placement section, but once you have programmed all the parts you use, the vision doesn't need much attention.) So, I do everything from 0805 up to 30mm FPGAs with it. It is marginal with .65mm pitch parts, but does great with SO chips and all passives. If you look at other machines, check carefully about the range of parts they handle, and the consumables. Some of these machines eat several vacuum nozzles at $100 a pop every shift, and guarantee a broken nozzle on any mis-pick or tumbled part, not to mention actual crashes. The CSM is VERY robust in comparison, uses steel nozzles and can survive most crashes without much damage. Having the experience with mine, I might have been better off to get a machine with vision instead of the jaw alignment, but it all depends on the kind of stuff you do. The later machines are generally marked with a /// after the model to indicate a later computer and brushless servo motors. There is the CSM-84 VZ which has vision and a Z axis servo, and the VANE which has vision and the auto nozzle exchanger. Not so sure about the ANE system, it uses different nozzles, and they look more fragile. I have made a big nozzle for FPGAs with a lathe and mill for my machine. I paid about $3600 for my machine including shipping and about 50 feeders. It cost me more than that to have a double door installed on my basement to get it inside! Obviously, I had a motivated seller who needed to get this machine off his floor to make room for new machines already in transit. Every day I communicated with him, the deal got sweeter. First, just the machine, then some feeders, then lots more feeders (all he had) then a box of spare parts. One thing is to get a machine that is highly regarded by the community (there are some REAL lemons out there) and be sure to get the manuals including the service manuals, because something WILL go wrong on these older machines. They ARE complex, mine has over 50 sensors and about 25 actuators.

BUT, they are usually too big in diameter. By custom making one with LEDs, you can fit it to be completely snug to the microscope body and sit up against the sides of the microscope, so it is as far out of the way as possible. We got a ringlight with a new Chinese scope at work, but it hung below the bottom of the scope and was over an inch wider than the scope itself, so I replaced it with my own LED ring light. > For large TQFPs, I anchor the chip body to the PCB with a dab of clear > nail polish, using the microscope for accurate positioning.

The Most Wonderfully Ridiculous Movie Computers of All Time

From: Jason McBrien <jbmcb1 at gmail.com> To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: Re: The Most Wonderfully Ridiculous Movie Computers of All Time http://www.starringthecomputer.com/feature.html?f=50 Weird analysis about the VAX 780 in Seven - I don't think it's outside the realm of possibility that a police department would still be using one in the mid-90's. The college I went to was still chugging along on an old Amdahl 370-clone in the same time period - as the primary mail server and host for various licensed apps (mainly SPSS) I have NO difficulty believing municipal departments would hang on to old gear as long as it would stay reasonably reliable. And, there is even STILL no shortage of VAX-11/780 parts at the brokers, if you know how to run the diags and swap boards. You could even repair the machine at the chip level with a soldering iron, solder sucker and dikes. There are pretty much NO custom parts in the entire machine except the fixed microcode fuseible PROMS, the LSI-11 and the inductors in the power supply modules. Given IT wasn't the hot cost center it is today, I'd imagine most police departments would be loathe to shell out for an upgrade to something that still probably worked just fine. Now, why the director put that thing the precinct room is another question. Artistic license? Now, that is VERY funny! Anyone who has ever walked behind a running 780 with a handful of papers at mid-thigh level knows what those cooling blowers will do! I can imagine the whole room being filled with whirling sheaves of paper! For those who don't know the 780 as well as I do (I was sysadmin on two of them, and also did a lot of hardware hacking and interfacing on them) they had 3 one-half Hp (I think) centrifugal blowers that sucked air down through the card cage and blew it out the back of the cabinet through 3 fairly small vents. The air shot out at at least 50 MPH, probably more. The 780 has a card cage that ran the entire length of the ~5' long cabinet, CPU at the left, memory in the middle and I/O sections at the right, IIRC. (Hmmm, have a vague recollection maybe the memory was at the left....) Power supply boxes were below the logic cards, blowers below that, and LSI-11 and it's floppy drive at the bottom left. Jon

PCS CADMUS 9700 System power-up difficulties

by p.gebhardt＠ymail.com

Hello list, ? some years ago, I got a CADMUS 9700 computer, a rather heavy system of the 80's from a german manufacturer called PCS. The system is built around the DEC QBUS, but uses a Motorolla 68000 type CPU. Finally, I found some time to have a look at it. Unfortunately, I didn't went far with my exploration. After having taken an hour to find out how to open this thing (plastic covers without screws are NOT fun, when they seem stuck), I cleaned it as it was horribly dusty und rusty. It must have spent some time in an humid environment. Deconnecting the drives and?applying power to?the switching supply turned on?the blinkening?kight of the ?green "RUN" button, but pressing it did not do anything. Afterwards, I deconnected the supply, checked that power connectors within the chassis were correctly seated and reconnected the power plug to the power-supply. Now, the green light did not blink anymore. In fact, since then, nothing ever happended again. The system just seems dead. I guess that the supply has a problem. It's difficult to check it, though, without schematics. It has a small ribbon cable which connects to a small PCB with several ICs on which can be found the "RUN"-button. I have no idea, which signals that supply needs in order to enter a state at which it should be on. The small PCB with the buttons and ICs could also be defective. ?There is also a key-switch, but I played with both positions and it does not influence anything on my system. The systems seem rare. At least, I could find only little information on the net and not documentation at all.Has anybody a clue on how to power-up this thing?Are there other owners of PCS systems, who can tell me who the system behaves upon applying power to the PSU and if it is sufficient to press the RUN-button to turn it on? ? Kind regards, Pierre ? ------------------------------------------------------------------------------- Pierre's collection of classic computers : http://classic-computing.dyndns.org/

Hi, I'd like to play with the OASIS operating system for the Altos 5-15 (downloaded from Dave's site). After logging in I get the '>' prompt. Apparently, they use some kind of stack within their CLI as I can use it as an RPN calculator (just like FORTH in OpenBoot environments). The usual candidates like DIR, CAT etc. aren't recognized, LIST gives 'File name missing', LIST * gives 'File extenstion missing', and LIST *.* gives, well, nothing. So, does anybody have (preferrably a scan of) the OASIS user's manual? Christian

PDP1 Music / Record sold

by jws＠jwsss.com

The fellow who posted the record some time back which was titled to be PDP1 music reposted the record for $299 and sold it. the reason to note anything about it is that I had emailed him about taking a capture of it and passing it along before selling the record The ebay listing up right now has a track you can download as long as it stays up. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170923504018 Here is the link to the song as well. http://ampnoise.com/mp3/MusicOnThePDP-1X_Pinafore.mp3 I thought it was nice of him to do that, as many people who list things on ebay would have bothered. I would say that it was just to sell the record, but I think the rarity of it to record collectors and a lower price is why it sold. Jim

And Fred replied: > Is it supported by current software? Kind of. It'd probably run Windows 98(it would definitely run Window 95) OK, but nothing newer from Microsoft as far as I can tell. Memory limitations within the confines of a P166MMX laptop of the day wouldn't allow anything newer to run. However, it would run various flavors of Linux or BSD without much fuss. I picked the 166MMX for my example as I have an old Dell laptop with a 166MMX, 640x480x256 color LCD, CDROM drive, 64MB of RAM, serial & parallel ports, as well as an early Soundblaster-compatible sound system in it that I use as a console for my PDP 8/e and PDP 11/34A systems. It is rock-solid reliable, and runs an older (late-90's) Red Hat Linux just fine. Don't know how it'd do on a current *BSD or Linux, though...if stripped down to eliminate all the GUI stuff, it just might be able to run something current, though it'd be pretty stripped. I think that if we never developed large-scale MOS and CMOS devices, and were stuck tech-wise with either small discrete transistor, or small-scale bipolar IC technology, we'd probably be lugging around "backpack" computers that have the rough computing power of a mid-1970's minicomputer, that'd run batteries that could be carried around for a few minutes -- enough time to perhaps to move between power outlets without shutting down. You'd end up having pretty well-developed leg, lower back, and shoulder musculature carrying such a beast around. TCP/IP Networking (not to mention wireless) not included. Of course, without the tech that came from LSI, we wouldn't have high-resolution LCD displays, either. Nothing like lugging a CRT around. The display would probably be a CRT or some kind of character-oriented plasma panel (Burroughs Self-Scan?) -- both big power hogs. Maybe the world would be better this way :-) At least we wouldn't have people trying to read their Email and TXTs on a cell phone while driving.

My understanding is that, in most jurisdictions in the USA, trash is "abandoned property" when you bring it to the curb, even in a designated trash container owned by your trash hauler. This is the result of court decisions allowing police authorities to search the trash without bothering to obtain a warrant. That seems to be the general take in the US. There have been instances of dumpster divers prosecuted, but it's for trespass.

HP Apollo 715t

by spectre＠floodgap.com

I'd forgotten I had this and where I got it from, but I was cleaning out one of my storage units today and found an HP Apollo 715t/33 (425t) (picture: http://www.floodgap.com/iv/1695 ). AIUI, this unit can boot both Domain/OS and HP-UX. I have a crate of HP-HIL keyboards from my 9000/350, but the manual indicates they won't work with Domain/OS (and a Domain/OS keyboard won't work with HP-UX). Ostensibly there is a switch on this unit which says what it's configured for, but I can't find it in the manual or obviously on the exterior of the unit. Any suggestions? I haven't fired it up yet. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- TV is chewing gum for the eyes. -- Frank Lloyd Wright ----------------------

Oh, also, 5.25" PC floppy drives

by fraveydank＠gmail.com

I have a number of 5.25" PC floppy drives that have sat in boxes in my parents' basement for years (reasonably well climate controlled, drives never got flooded, etc.) Media preservation isn't really my thing, since I don't have or come across a lot of media to preserve, but I figure four or five 5.25" drives could find a good home through this list. They worked last time they were tested, and I might be persuaded to test them again if necessary. I even have a 5.25"/3.5" dual drive, though its cosmetic components are beginning to wear a bit. Same deal, free for price of shipping. - Dave

Manchester Baby

by robert＠irrelevant.com

I've been meaning to try and scan this for ages ... Mention of this in the article linked to from the love letter post made me remember it. Here's a news article about the Manchester Baby, from 1978. ("30 years ago today..") http://www.irrelevant.com/manchesterbaby/ Apologies for the poor formatting; original was almost unreadable in places. (Not helped by lots of brown sellotape holding it into my old scrapbook!) At some point I'll find the time to tidy it up. Rob

Only Series 400 HP "Apollos" had both HIL and Domain keyboard connectors, and all Series 400s will run Domain/OS. Even though they're post-buy, it seems as though HP did put some work into them - my 425s is well-built and has pretty much everything you'd need to get a good system running without looking for parts (SCSI and Ethernet onboard). The downside is no ATR if you need to have it talk with older boxes.

unibus to modern disk interface?

by jwest＠classiccmp.org

Just curious, did anyone ever do a Unibus->IDE, etc... anything to interface a modern drive to unibus? I see from googling that Brad Parker had an excellent concept & initial design. Basically a unibus controller that could impersonate several different controllers & disks... Anyone know if this project (or a similar one) ever was completed? I'd be most interested in keeping the RL02 on the 11/45, but would love to have something larger for builds that could be easily removed and thus keep the system "original". J

Ebay Cray T94

by elson＠pico-systems.com

After looking at the other photos of the internals, I don't think that skid is up to the task. Since they cracked one of the hatches for illustration, makes me wonder what sort of juice is inside to cool it with. If freon is it still legal? As to whether it is touchup paint, I would also suspect it might be some sort of treatment for the coolant, but not sure what that is. Certainly possible it is what you say. that is a lot of aluminum though a wonder a crappy skid like that hasn't given out. The coolant is Fluorinert, a fluorinated hydrocarbon. It is not an ozone-depleting substance, as far as I know, but would still probably be considered hazmat which would complicate shipment. Probably the best thing would be to drain it, and ship separately in barrels. Jon

WATFOR for IBM 7040

by colineby＠isallthat.com

Its also possible the Manchester University Medical Computing Unit archives will have such a request. They used both a 7040 And 7090. The also made a number of software requests to other institutions. The archives are deposited with the UK's National Museum of Computing. I'm involved with their initial conservation, so this is something I can check, though there may be a little lead time to do so as its mostly uncatalogued, and not at all digitised yet. Are you looking for the compiler, information about its historic distribution and licensing patterns, or something else? --Colin SPC <spedraja at gmail.com> wrote: >Hello. > >Im' playing actually with diverse emulators for the IBM 709x and the >software available for them (IBSYS and CTSS).

The 3174 Token Ring output connector is a 9 pin D-sub like a serial port and I use a small converter that has a 9 pin D-sub connector and an RJ-45 socket. It is a generic item that you have to open up and connect the two connectors however you want for your application. The connection diagram was on the internet at one time. I got this at a local hobby electronnics store that burned about a year ago and I have no idea where to order such a thing. Using standard ethernet cables to go from the 3174/converter to the concentrator to the Cisco is not the perfect way but it works if the cables are kept as short as possible so the impedance mis-match is not to bad.

I was explicitly replying to (and specifically quoting) Fred's post including the use of colour in the email no-nos like yodelling jellyfish etc., and I think that your screenshot actually does make my point (no doubt unintentionally) that colour can be useful (as opposed to the jellyfish). That Mouse and you obviously chose to ignore the explicit (con)text of my post and instead "*read into*" my post that "the colour in question was *supposed to be* encoded into the on-the-wire form of the email" (*s mine) prompted my ironic, "glad you agree". If I receive an email appropriately and tastefully using colour and/or HTML then I prefer it to the limitations of chevrons, plain-text-only, etc.; if it mattered enough to me to justify installing a reader and/or plugin to convert plain incoming mail then I would. But I don't tell anyone how they are "supposed to" format their email; I'm much more interested in the content than whatever format they chose or had to use. If there's an issue that they may be unaware of I'll ask; otherwise if it matters I'll do what's required at my end in order to read it. Conversely, although I bristle a bit at people telling me how I'm *supposed to* format *my* email and with whatever favourite client of theirs I should replace my obviously defective one, I generally go along with whatever prevailing standards are on mail lists like this one, even when I don't agree with them as in the case of the top-posting 'standard'. And yes, I will occasionally register a vote in support of letting people post however they prefer or have to, without chastising them whenever they top-post (especially when they didn't). With clients that hide the quoted text by default why does it even matter? m

DMC11 at Ebay

by vaxorcist＠googlemail.com

Who is bidding for the DMC11 at Ebay? I'd just like to know who else (besides me of course) is interested in that very special old DDCMP communication adapter. I cannot imagine that any DMCs are still in productive use today, so there's probably another collector out there somewhere ... I would be nice to get in contact with that special person (no matter who wins the auction) to exchange experience. My motivation to own a DMC11 is to run DDCMP DECnet under VMS V2.x (no Ethernet support with VMS V2.0 yet) on my VAX-11/750. There are still some lesser problems to overcome, e.g. obtaining DECnet for VMS V2.x ;-)) I know the bidder might as well (or even with greater probability) want the DMC11 for his/her PDP-11 rather than for a VAX. Maybe one day some crazy collectors will connect their VAXen or PDP-11s via DMC11s and dial-up lines every now and then? Regards, Ulli

I mentally append smileys to most posts in a thread like this, on the assumption that intelligent men (women presumably having better things to do) would not spend time and energy every few months or so *seriously* arguing *once again* about where to place an e-mail reply; the humour really becomes apparent when you show a thread like this to a 'normal' person... But I wasn't saying anything about how, when or where it's done to disagree with anyway, merely stating that IMO using colour for clarity when possible and appropriate doesn't necessarily belong in the same category as Fred's wallpaper, dancing kangaroos or yodelling jellyfish; it's just one more often useful option that's come along since the text-only monochrome screens that many of us started with and seem to want to hang on to (at least in this context). m

What makes it worth the time you spend on it? What purpose does it serve except to expose your bigotry?

I think if you put on your glasses and/or improved your reading skills somewhat you'd see that I did exactly that (although I happen to think it's a pointless and cumbersome relic of the golden days of Usenet glory...)

I think you need to apologise. > > Alexey ----- Reply: As a matter of fact I see a fair bit of that on this list as well, by the same group of regulars: stereotypical judgement and blaming of OUTSIDERS, i.e. ignorant 'lusers' who don't know or care how their computers work, the intricacies of TCP/IP or their operating system, who top post, use M$ software, etc. etc., and are perhaps busy running businesses, performing brain operations, whatever, instead... And Dave is of course implying that he's NOT a member of the group he's disparaging; after all, HE knows that they speak Portuguese in Brazil! As a matter of fact he is in fact echoing and defending the stereotypical view of "people in other countries," i.e. OUTSIDERS... (and thus perhaps even offending some of "them" ;-) So, it's OK to insult and offend members of a certain group with this sort of stereotypical judgement as long as you yourself are a member of that group (albeit presumably one of the exceptions who doesn't fit the stereotype...)? As long as I'm an African-American myself it's OK for me to say "yeah, we really are inferior somehow, and there's a REASON why folks believe that about us"? In that case I do apologize; I naively thought that derogatory stereotypes were sort of inappropriate regardless of the source. m BTW, I have a Brazilian girlfriend, so I not only know that one speaks Portuguese there but I'm also intimately acquainted with the Brazilian wax look...

Things with current mailing addresses on them

by dgriffi＠cs.csubak.edu

In my storage unit there keeps bubbling up stuff that author Jerry Pournelle was sent to review for Byte Magazine. When I sell them, instead of giving people the actual letters and such (which has Jerry's still current home address), I give them a censored photocopy. What should I do with these originals? I've been building a small file of them for the past few years. Should I just wait until Pournelle dies and then unload them on Ebay? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

Ebay Cray T94

> > From: "TeoZ" <teoz at neo.rr.com> > > Power supply requirements are a bit out there for home based collectors, and > what software would you run on it (I assume everything was custom per > order)? > Right, on the nameplate is shows 68 KW electronic dissipation, then you have to supply water chilling for a 68 KW load. Then,. you need a pretty massive support computer to run this thing, I think the last ones were VAX 8000-series machines. They had a stock OS, booted from the support computer, which also provided disk, tape, graphics, etc. So, for your typical US home service, you'd probably need a 200 KVA service, at 120/240 V that would be 833 Amps. You'd also need a cooling tower in your back yard that would send a cloud of vapor all over your neighborhood. Jon
