OT(ish): Using "Classic" CPU as power resistor...

How about a light bulb? I'd try a bulb for an automotive brake light. If one's not enough, you could connect a few in parallel. If you find the 6V variety, it might work even better, but you should at least draw some reasonable current with the 12V ones. If you really wanted to have fun, you could try a headlight... BLS

I want to sell my 11/24, anyone interested?

by charlesmorris＠hughes.net

I have too many projects (including my 8/A and 11/23+) and not enough time, and don't want to keep my 11/24 sitting until the mice build nests in it. It seems to be alive (comes up to ODT on the console port) but I haven't tested it otherwise. I posted the card list several months ago on cctalk but to save you looking it up, here it is again: 1 M7133 KDF11-UA 11/24 CPU with line clock and 2 SLU 1 M7134 KT-24 Unibus map, extension to 22 bits 1 M8743 (ECC RAM, either 512 Kb or 1 Mbyte) 2 M8722 (ECC Memory either 128 Kb or 256 Kb each) 1 M8188 FPF11 floating point processor 1 M7762 RL11 disk controller RL01/02 1 M7258 LP11 printer controller 1 DSD A2130-6 disk controller? 4 M7819 DZ11-A eight RS232 ports each 1 M920 Unibus connector 1 M7297 RH11 MASSBUS Parity Control 1 M7296 RH11 MASSBUS Control & Status Registers 1 M7295 RH11A MASSBUS Bus Controller 1 M7294 RH11 MASSBUS Data Buffer and Control 3 M5904 RH11 MASSBUS Control Transceivers 1 M9300 Unibus terminator 1 M9312 Bootstrap Terminator Looking for a good home, please make a reasonable offer. Will be going on that auction place next. Shipping may be expensive (that chassis/power supply is *heavy*). Can email a pic. I'm in south central Missouri, zip 65775, if you know what it weighs and want to estimate shipping. thanks Charles

RK05 disk packs

by chd_1＠nktelco.net

I have just gotten about 80 RK05 disk packs for a PDP-11. They have been stored in an office environment, but most have not been used for at least 15 years. Some have labels indicating they were cleaned by SCOPUS in the late '80s. Any recommendations on the best way to store them would be helpful. If anybody is interested in some of them, they can be had for the shipping. Contact me offline if you are interested and we can talk about the details. I am located in Ohio, USA 45865.

BA11-K low AC output levels

by fireflyst＠earthlink.net

Okay, so, I'm back to working on my /34. I think I made significant progress tonight. What's going on is, I've narrowed it down to low AC levels coming off the transformer. The printset and H7xx modules specify an incoming AC of 20-30v (printset says specifically 28v.) All lines coming off the transformer at P1 are reading a value of 10-15v. So that leaves two possibilities. It's either the transformer, or the AC input box. I'd like to test the levels coming out of the input box, but I wouldn't know where to go, as my understanding of electronics fades fast at this time of the night when I've been up since 07:00. Okay, so maybe I traced it back that far, it got more complicated, and it's late and I'm feeling lazy and hoping someone will throw me a bone here :) in any case, advice is always appreciated. toodles Julian

OT(ish): Using "Classic" CPU as power resistor...

by zmerch-cctalk＠30below.com

Rumor has it that Brian L. Stuart may have mentioned these words: > > From: Roger Merchberger <zmerch-cctalk at 30below.com> > > The problem is I need to use a PC power supply (AT-class with it's own > > power switch) as a 12V power source, and the only one I have access to > > needs a minimum load of 3Amp on the +5Volt line. > >How about a light bulb? I was thinking of that (and was also suggested by a cow-orker) but I was unsure about how to handle the function of variable resistance WRT heat dissipation; and also, if a bulb fails, it fails open-circuit which means there's no more voltage regulation. I suppose with enough bulbs, one could build enough redundancy into the system... I may hit an auto-parts store tomorrow anyway and see what I can scare up; but having ready access to several CPUs (2 each 80486SX's & a P75 Overdrive on a quick search) I figured that a 5V CPU would be a good way to dissipate power from a 5V source, and the 486 would prolly have the highest current draw of any easily available 5V processor. But again, I could very well be wrong... No, I'm *not* using any of my 6809s!!! ;-) Thanks!

OT(ish): Using "Classic" CPU as power resistor...

by zmerch-cctalk＠30below.com

I need some help from those who are a lot better than I in hardware design... The problem is I need to use a PC power supply (AT-class with it's own power switch) as a 12V power source, and the only one I have access to needs a minimum load of 3Amp on the +5Volt line. By my rough calculations and allowing for wiggle room, I'd need a 20-watt power resistor of 1.5 ohms to keep the critter happy. "Bare minimum" is 15W, and I could squeak by with that if I wire the fan to the 5V line instead of the 12V... but even when I'm expected to perform a "miracle" I like to have a little wiggle-room. ;-) Problems I have are: 1) I need this by Monday, and 2) I don't keep 20-watt power resistors in my back pocket. Had I a week, I'd just order the right tool for the job - I don't have that luxury. ;-) I was thinking I *might* be able to cobble up enough lower-end power resistors & figure out how to stuff 'em together to draw 15w+ of power, but then I thought: What if I took an older 5V CPU (say... an 80486) and wired 'er up to just Vcc & Ground - how much power would that use? [[ I've started some google searches & I will continue, but I was hoping others here would have better ideas than my lame-azz neurons & google so far ]] I could also wire-wrap all the address/data lines to Vcc if that would add a enough extra current draw to make 'er worth my while... For those who are in lust with the "older, but still plentiful" CPUs like that, then turn away now, you didn't see this, I was never here." ;-) Any ideas will be most appreciated! Thanks!

anyone have a terminal server?

by adamg＠pobox.com

A somewhat belated reply to this thread, as I read the list irregularly... DECserver series: Some models are LAT only (such as 100, 200, 90), some also talk TCP/IP. Note there is also a TCP capable version of the 90 called the 90TL. I believe there's an open source LAT daemon now. The 90 is a compact 8 port module that plugs into the DEChub-90 or DEChub-1. Some of these will need a MOP server to boot. Any of these should be OK to attach terminals to. IIRC, I wasn't able to associate DECserver-100 ports with services for attaching it to a console port ("reverse LAT"), only some models support that. DS550 is a big box with a PDP inside, 90 and 900 are little, 100/200/300 are in between. Lantronix: ETS series terminal servers are compact boxes with varying numbers of ports, with a DECserver-like interface. They can be used as terminal servers as well as console servers. EPS series devices are intended as print servers -- IIRC you can use as console servers, but not as terminal servers, because the commands for outgoing connections are gone. There's also the LRS series, which were intended as small RAS boxes, but will also be OK as console or terminal servers -- but the LRS2 hardware seems to have problems. The LRS1 is OK. They also have a few other product lines such as MPS. Many of their products talk both TCP and LAT, some of them are TCP-only unless you purchase a LAT license. Some of them can be used as TCP/LAT gateways. Shiva LanRover: Intended as a RAS, can also be used as a console server. 1U rackmount box with up to 8 ports. Probably not useful as a terminal server, unless you have a machine that can talk the Shiva Hose protocol and take over the ports. (It's been a while but I don't believe it wanted to give a login prompt to an attached device that doesn't act like a modem.) They also made an OEM version for IBM. TCP. Xylogics Annex: A few different products, usable as console or terminal servers. Annex 3 squeezes dozens of ports onto one box, with Centronics connectors. Livingston Portmaster: This series was popular with ISPs as a RAS, can also be used as a terminal or console server IIRC. TCP. Bridge Communications CS/100, 3Com CS/2100: Not sure what exactly these will do, but without the boot floppy or TFTP image, they won't do much useful! The software was available in several versions including one that only talked OSI. A dozen or so ports. Xyplex, Emulex, others: Various DECserver workalikes. LAN Access LANAserver: Dunno much about this except it was available with 4 and maybe 8 ports, it's 1U and it has an LCD on the front. Company was sold to Digi in '95, they sold the product to NNTI, NNTI went out of business. I think Digi might have also had their own product. Cyclades: They make some sort of nifty little box with L*n*x inside, I think it's intended as a console server. Cisco: They made a box with a bunch of serial ports, I think it was intended as a RAS but could be used as a console server and maybe a terminal server. Hmm, I know I'm forgetting something here... -- Adam

Looking for MSJ article

by cclist＠sydex.com

Does anyone have a copy of the September 1984 Microsystems handy? I'm interested in the article about replacing the 8085 on a Compupro dual-CPU board with an NSC800. I'm doing a similar project, but am having some real problems. I can read and execute instructions from EPROM just fine; reads and writes to I/O devices are just ducky, but DRAM access is unpredictable at best. Logic analyzer waveforms look textbook, so I'm wondering what I'm missing. The board does use the Intel 8202 DRAM controller and I know it's a twitchy part, so I'm wondering if there might be a marginal timing issue. Cheers, Chuck

Just wanted you to know that I am the one on ebay with all the old vintage terminals, and keyboards thermal printers, Misc Keyboards, etc. I seen that you were asking about the update so I was just letting you know personally that I am probably fixing to list them for cheaper on ebay, and not go through all the checking and testing. Its just taking up to much of my time, and storage space. Maybe I need to have a garage sale....lol. Now In the auction if it says that its been checked its been checked on what it says. If your interested or have any questions please, just send me an email or offer. Thanks, Greg (Gessman Business Services) *Friday, May 12, 2006, 2:20:43 PM*

Anyone have a cache of Vaisala docs?

by ethan.dicks＠gmail.com

I am cleaning out a box of old gear here and ran across an interesting doo-dad... a Vaisala "MPT 11" - what seems to be a "manual papertape reader" - smallish PCB with a U-shaped plastic tape guide for what I think is reading in the calibration papertapes for Vaisala sondes (when launching a balloon, certain models of sonde have a papertape in each one that gets fed into the telemetry box prior to launching). I googled for a few references, but only turned up part numbers, no technical docs. Not really surprising for embedded stuff from 1999. There are other things in the crate - what look to be single-Euroconnector-attached boards with embedded GPS receivers, etc. (also from 1999). One CPU board looks to have an 8031 at 7.mumble MHz, and there's a DC-to-DC converter or two on the same sized boards. Probably from a rack-mounted telemetry box they used to have around here. I also have small box of the GPS units from the sondes themselves - helical copper wire antenna sticking out of an RF shielded board. There's a 3 or 4 wire interface, two leads of which go to an 8-pin SMT 78L05, so power should be easy to trace, the remaining lead or two is going to be some format of serial data, probably TTL, the only question is what format the data are in. If anyone has or knows of a Vaisala technical docs repository, I'd love to hear about it. Thanks, -ethan

>> A large card ("Newport Graphics"?) but appears that 4 RAMs (?) >>were not populated at initial manufacture (which suggests it >>is a lower-end card?) >Yeah. XL-8: 8-bit, non-accelerated video. Not really "non-accelerated", just without geometry or a Z-buffer. XL video is (of its generation) the fastest at 2-D tasks, noticeably faster than XZ. Not sure against Extreme (you still have the pipeline overhead, but 2 REs on GU1). In addition to the extra VRAM, there are several ASICs that are unstuffed on XL8- possibly colormaps, I can't remember right now. The chip under the heatsink is a REX-3 raster engine. It takes care of everything that "accelerated graphics cards" for the PC did and more. The CPU takes care of geometry and Z-buffer, coordinates are sent to the card for raster operations. On the back: the RCA is composite-in, the mini-DIN is S-VHS (Y/C) in. The "bidirectional audio" is digital I/O Jules Richardson wrote >Has anyone ever tried a wide SCSI controller in the same physical machine as >the framebuffer?

I believe there are wide SCSI GIO32 cards out there. I've never worked with a Challenge, but in the Indy the mainboard -> graphics is a modified-connector GIO-64, the expansion bus on top of the framebuffer is GIO32-bis. I have no idea how they break up the channels (Indy can have 2xGIO32 + GIO64 graphics, whereas Indigo2 is limited to 2xGIO64 whatevers). I2 would likely work out of the box, since there are the 2x Fast-SCSI channels available. Of course, what they wanted you to do is buy an Onyx . . . (I suspect that this is why the genlock disappeared when they moved from Express to IMPACT graphics in the Indigo2)

Stewpit Indy questions <:-/

by compoobah＠valleyimplants.com

The ARCS machines (IP19, IP22 and above) are very forgiving as far as type of CD-ROM drive, I've used Toshiba and Apples just fine on mine. Older 4D machines needed some firmware tweaks that made the drive look like a fixed disk for the initial SASH load from PROM. The "video" thing on SGIs is substantially different from PCs. What is called "video" in PCs is called "graphics" in SGIs (and many other workstations). SGI graphics are very good, even 8-bit Indy. The video addons were for video feeds, and included Indy Video and Cosmo Compress boards. Stock Indys shipped with video-input (composite, S-video, and proprietary digital), but no output. Indy Video provided this. Disk bandwidth is not great enough to capture full motion/screen video to disk without the Cosmo Compress card. Both options are expensive, if you want to edit video get a Mac with FireWire. Sound is quite good, and includes digital I/O (but not S/PDIF- for that you need an Octane). I'd recommend IRIX 6.2- it's fast on older hardware, 64-bit (but the Indy isn't quite- it will still run N32, though, which 5.3 won't), and has POSIX compliance via patches. IDF/IDL can be downloaded, and GCC 3.4 is pretty decent on MIPS hardware. Building software on 6.2 is less "informative" than 5.3, also. In any case, a good set of electronic manuals ships on the distro media, as well as being available from techpubs on SGIs website. Gotchas- don't set anything to SCSI ID0 - that's the controller on SGI machines. Enjoy your new toy- you'll probably start saving up money for an Octane.

by dgy＠DakotaCom.Net

Hi, I've got an Indy that I would like to get working. The first thing I notice is a *slot* (in the plastic housing) for some sort of removable media (floppy?) but no corresponding drive inside. Is this intended for a floppy? Or, some other similar (physical) sized medium? I assume that whatever sort of drive it is, it uses a SCSI interface (I don't see any other provisions)? How is (whatever) *mounted*? There is a sled for hard disk in the "slot" below this but no obvious clues as to how to mount anything *above*! And, what sorts of add-ons (?) mate to the main board (I see what appear to be two daughtercard conectors). Lastly, is any of this worth playing with? Thanks! --don

The longer answer is you have to program the correct clock and tell the FDC to do FM not MFM (cammand bit). Also you have to specify (the command) HLT, LUT and STEP times as needed. Allison

IBM NetStation 300 PSU

by tarsi＠binhost.com

Greetings. Picked up an IBM Network Station 300 from a surplus place yesterday for $5. Unfortunately, it doesn't come with a power brick and there's no markings as to the power requirements. Does anyone have one of these and can quick glance at the brick and tell me what the voltage is and the polarity? Much appreciated. Nathan -- ------------------------------------- Nathan E.

BA11-K low AC output levels

by henk.gooijen＠oce.com

Hi Julian, without looking at the diagram (I am at work now). True, the incoming *AC* voltage to the power bricks is some 22 V. I assume that P1 is the Molex connector that has (IIRC) 8 black wires which are 4 2-wire groups of the AC supply to the 4 bricks. In that case, measuring 10 to 15 Volt (AC) is rather low. The H744 (25A) or H7442 (32A) 5V bricks should work at 10-15 VAC input, but what will the AC input voltage do under load condition? Is the mains input voltage correct (what you get from the wall outlet). Careful! Does that match the spec of the PSU? - Henk. > -----Original Message----- > From: cctalk-bounces at classiccmp.org > [mailto:cctalk-bounces at classiccmp.org] On Behalf Of Julian Wolfe > Sent: donderdag 11 mei 2006 8:41 > To: General Discussion: On-Topic and Off-Topic Posts > Subject: BA11-K low AC output levels > > Okay, so, I'm back to working on my /34.

Looking for a DSSI disk & cassette for a VAX 4000

by jplist＠kiwigeek.com

Greetings all; Picked up a VAX 4000-300 just the other day, and as usual at surplus places, the disks were all stripped out. As well as the cassettes, naturally, the lazy sods. Anyways. Does anyone have a DSSI disk and VAX 4000 cassette they'd be willing to share? Thanks all; JP

Gauging interest for an idea I have - feedback please! :)

by fireflyst＠earthlink.net

Hi everyone. In the ClassicCmp IRC this afternoon I brought up the idea that I have of starting a quarterly newsletter about vintage DEC systems (1960-1995 or so.) The thought behind this is that as opposed to reading mailing lists wehere you get snippets of information on specific problems, you would read full articles pertaining to both specific and general topics. Possible categories could include: - tools and test equipment reviews - general care and maintenance of a computer in a hobbyist environment - safety notes - specific software notes - getting started with any number of vintage software systems - emulation - interconnectivity between vintage systems, and also to the modern computing facility Now, my personal preference would be to do this on a quarterly schedule, and with old school production values (RUNOFF or some other vintage textsetting system.) Also, the magazine would be based on contributions, so it of course would only be the cost of media and postage. I would also plan to make the back issues available as downloads after 1 year (in PDF or some other universal form) with a printed copy available on request. So let me hear what you think! Julian

Building a RS-232 fiber converter?

by ethan.dicks＠gmail.com

With the talk of 20mA converters, it reminds me to ask... is there a simple schematic for a basic RS-232 to fiber media converter? In the real world, I'd just pick a pair up at a Hamfest (or get a mate for the single-fiber AT&T converter I have at home)... here, though, with no planes due in for almost six months, it's make it or do without. I can harvest the ST-connector LEDs/phototransistors from a box of soon-to-be-discarded AUI-to-10BaseFL transceivers, and I do have enough MAX232-type chips that I can easily do it from a single supply... the question just becomes... what goes in the middle? The station here is wired with CAT5(e?) and fiber (mostly multimode, but some single mode)... it would be handy for me here to be able to have some remote serial thingies without depending on terminal servers/reverse telnet, etc.... just a small box with a DB25 or DE9 connected to another via fiber. 19200 bps would be great, but even 4800 bps would be better than nothing. Anyone have any ideas on how to construct such a beast? I can build pretty much anything from a schematic or even a napkin, but I'm not really a designer. If it's as simple as hooking an LED to the TTL output of a MAX232, and the phototransistor to the input of a MAX232, that'd be super, but I suspect that there might need to be a little more to it than that. Thanks for any input/direction/etc -ethan

ASR33 Current Loop Converter

by sethm＠loomcom.com

Hello folks! It's good to be back on the list after a... well, I don't know how long, something like a two or three year hiatus. At any rate, I'd like to get back into things by asking whether anyone has good plans for building a 20ma current loop to RS-232 converter. I recently found a Teletype model 33 ASR at a flea market for $40, along with manuals, and I've nursed it back to health. With cleaning, degreasing, and a proper lubrication job, it seems to be working perfectly (well, 99% perfectly) in local mode. I'd like to get it talking to something that speaks RS-232. I've found a number of solutions for sale in the $50 range, but I was hoping to be a cheap bastard and build one myself. I've found a few schematics for hacks online, but no definitive plans for a reasonably robust home made solution. Yes, I suppose I could try to design my own. My horrible, embarrassing secret, though, is that while I'm a good programmer, I suck at circuit design. Never really got it. I can follow a schematic and solder my way to happy results, but don't ask me to design a light switch. I'll get it wrong. I've scoured the logs here, but I haven't found what I'm looking for. Anyone know where I should look? Otherwise, I guess I'll just have to give BlackBox my $50 and swallow my pride! -Seth

Anybody here famialr with a Winchester Systems Flashdisk RAID system?

by rigdonj＠cfl.rr.com

I found one of these today and picked it up. It clearly says the model is "FlashDisk" but it uses standard SCSI drives (10ea Seagate ST336704LCs specs at <http://www.seagate.com/support/disc/specs/scsi/st336704lc.html> ). I searched the net and found plenty of talk about it but no details and all the talk seems to be about Flash memory emulating disk drives. What's the story here? Joe

Heathkit EC-1 bootdisk wanted ( sort off..)

by tshoppa＠wmata.com

Jos wrote: > - Is it just my impression, or is any problem I can tackle with an EC-1 > much faster handled with a pocketcalculator or a slide rule? The true value of analog computers comes in when you stop dealing with "static" math and start dealing with "dynamic" math. In particular, capacitors as circuit elements let you build integrators and differentiators. These let you simulate and solve differential and integral equations. These are VERY MUCH of interest in the real world. Much work on chaos theory etc. was initially done on analog computers. (e.g. Lorenz Equation). Correct me if I'm wrong, but the EC-1 does NOT contain a general purpose 4 quadrant multiplier, right? This will limit you to rather dull (but still quite common) differential and integral equations and make it difficult to do the Lorenz equation for example. And recording the output of an analog computer is most easily done with a scope or pen-plotter. These can be added to an EC-1 quite easily but are not the basic setup. Tim.

Wang OIS60 media?

by julesrichardsonuk＠yahoo.co.uk

Hi all, Just been offered a Wang OIS60, which sounds like a reasonably interesting machine (cardcaged-tower, ST506 disk, Z80 CPU, support for 8 terminals). The owner's unsure as to whether there are any system disks - and I'm wary of us taking this thing on if we can't rebuild it when the hard disk eventually dies. So, anyone have one of these and have the installation media preserved anywhere? (along with the hard disk formatter - hopefully Wang weren't one of those companies that set hard disks up at the factory and then shipped them out) cheers Jules

HP and clear plastic cases

by everett＠kaser.com

I spotted this message on cctech several months ago, and tried to join the group then, but never heard back. Suddenly today, I received my "welcome" message. Takes a while, I guess. :-))) Anway, back in 2003, folks were talking about an HP-85 with a clear plastic case that was for sale. Joe rigdonj at cfl.rr.com wrote... > No it's a prototype. HP made clear models to test air flow (and heat > dissapation), parts clearance, etc. That is absolutely correct. They almost always molded 25 to 100 case parts in clear plastic, primarily for checking how everything fit. (All of this is from the point of view of the Corvallis OR division, which made the calculators and the Series 80 machines, as that's where I worked.) I've still got a clear cases on my HP-41, my HP-85A, and my HP-87 (although, unfortunately, the CRT has gone black on the HP-87 :-(. >My guess is that HP made fewer than 10 of these HP-85s in a clear case. > I don't think so. I've only heard or seen of ONE clear unit os any model > so AFIK HP only built one of each. I'm sure that they molded at least 50, and possibly 100 sets of top and bottom cases in clear plastic for the HP-85 and HP-87 (top case only for the HP-87, since the bottom case was the same as the HP-85). (The number 50 sticks in my mind the most firmly, but it could have been as high as 100.) In fact, if there had only been 10 or less made, there's no way in h*ll that I would have been able to snatch a set! :-) Anyway, it's a little late, but I thought I'd clarify the historical record in case anyone cared.

11/45 angst

by jwest＠classiccmp.org

Ok, got a bit of time yesterday and today to clean up the work area so I could work on the /45, and to actually go through some of the tests Tony had suggested. First, let me describe the current setup, as I changed things around a bit in order to simplify the setup. Here is how the machine is configured right now, and how it was configured during the following tests. I did not leave out any cards in my list here, so if you don't see it listed, there isn't anything in that slot. Current configuration System Unit 1 (A-B) M930C 2-5 empty 6 (A-F) M8100 7 (A-F) M8101 8 (A-F) M8102 9 (A-F) M8103 10 (A-F) M8104 11 (A-F) M8105 12 (A-F) M8106 13 empty 14 (A-F) M8116 15 (C-F) M8109 16-25 empty 26 (A-B) M9200 side 1 (C-F) M7856 {note, the LTC option on this board is enabled, there is nothing in slot 1C} 27 (A-B) M9200 side 2 (C-D) Dual Grant 28 (A-B) BC11A-0F side 1 (C-D) Dual Grant MF11-L in system unit 1 (A-B) BC11A-0F side 2 (C-F) H214 2 (A-F) G231 3 (A-F) G110 4 (A-F) G231 5 (A-F) G110 6 (C-F) H214 7-8 empty 9 (A-B) BC11A-15 side 1 BA11-KU with DD11-DK 1 (A-B) BC11A-15 (C-D) Dual Grant 2 (A-F) M7762 3-7 (C-D) Dual Grant 8 (D) single grant 9 (A-B) M9312 (D) single grant Connected to the M7762 is an RL02, and connected to the M7856 is an ADDS vt100 clone. Before I go further, I should point out that the system DOES have some basic functionality. It CAN boot up xxdp, and does pass a few front panel tests. The basic problem is I suspect that interrupts aren't working right. I suspect this because when trying to boot a known good RT11 pack, it hits the disk for at least 30 seconds before halting, and it's definitely progressing and not just retrying one read over and over. Many diagnostics fail, but they seem to fail whenever something with interrupts is being tested. Let me also say I'm new to the /45, but learning, so I'm not entirely 100% sure I'm operating the front panel right. In other words, it is very possible this is all due to some stupidity on my part! Initial setup - I power on the system with the front panel knobs set to cons phy and data paths. The console emulator "@" shows up on the system console. The status lights lit are Pause, Master, and Kernel. I type "DL" on the console, the lights start counting up steadily - because I forgot to hit load on the rl02. I hit load and when it goes ready the disk chugs for a minute then prints the XXDP loaded message on the console and prompts for date & time. I can load a few diags and it finds them at least. There is basic sanity here. I happened to find a program on the diag pack called "SIZER". Below is it's output from powerup, which may be helpful to someone "in the know". It reads... --------- p 031757 077317 030217 034317 @DL CHMDLE0 XXDP+ DL MONITOR BOOTED VIA UNIT 0 16K UNIBUS SYSTEM ENTER DATE (DD-MMM-YY): RESTART ADDR: 072010 THIS IS XXDP+.

Not sure why it shows as a DP11, maybe that's a bug in this sizer program. In any case... First, Tony suggested I store sucessive bits and read them back, ie. start at loc 0 and store 0,1,2,4,8 etc. I did that. All stored and read back correctly. Then Tony suggested that I run instruction diagnostics. I did that, and below is the output. ----------------------------- 022700 000012 001000 000020 @DL CHMDLE0 XXDP+ DL MONITOR BOOTED VIA UNIT 0 16K UNIBUS SYSTEM ENTER DATE (DD-MMM-YY): RESTART ADDR: 072010 THIS IS XXDP+.

The cursor just sits to the right of VPC= on the last line, forever and the processor is halted. I'm betting money this is a bad result from this diagnostic. No clue what it means. But.... read on.... There is a website for "hints on testing a dead pdp11" that I used the line time clock test on. Here is what the website says to do.... ---------------------------- Line Time Clock Interrupt Test Most of the older PDP11's had a line time clock that would interrupt at mains frequency (50 or 60Hz). On early LSI-11's, it was not programmable but enabled by a switch on the front panel. Load the following program (which is just a trap catcher and interrupt enable), and start. If an early LSI-11's, substitute 000240 for the lines marked #, run the program for a second or two, then enable the clock. The program should halt at address 104 (the interrupt vector address is 100, and the vector is loaded with 102, which then executes a halt at 102, the PC will then be 104). Location Contents Opcode Comment 001000 012706 mov #770,sp set the stack pointer 001002 000770 001004 005000 clr r0 memory pointer 001006 012701 mov #2,r1 trap value 001010 000002 001012 010120 loop: mov r1,(r0)+ set trap vector value 001014 005020 clr (r0)+ set halt instruction in trap 001016 062701 add #4,r1 update r1 for next trap 001020 000004 001022 020600 cmp sp,r0 load up to stack pointer 001024 001372 bne loop # 001026 012737 mov #100,@#ltc enable clock interrupt # 001030 000100 # 001032 177546 001034 000777 br . loop for ever If the processor doesn't halt, then your clock isn't running. If it halts at 6, then the clock register is missing. -------------------------------- Now, I entered the above program. When I run it, it halts with PC = 4, NOT 104 and the data display shows 000770. Yes, I'm sure there are no burned out front panel lights. To my limited knowledge, this sounds like the program got the interrupt but instead of jumping to 100 for the vector, it jumped somewhere around 0 or 2, since the PC said 4. The plot thickens though, read on.... I took the above program and modified it to set bit six of the receive CSW to 1 (receive character interrupt enable) on the SLU, I believe I did it correctly by just changing location 1032 to 177560. When I run this program, the system is looping at 1034 just like it should... until I hit a key on the console. The moment I hit a key on the console, the processor halts with PC=4, and the data display shows 000770. So it seems that whether the interrupt comes from the LTC or the SLU, no matter what it halts at loc 4 with data 770.

Of course, I am not skilled enough to know where to go from here. I can say that my processor cards (M8101 through M8106) were borrowed from another collector and tested before I got them, but I guess we can't rule out a problem with those. All the other cards, including terminators and grants, are mine. The BC11A-15 was replaced recently with a brand new one. I've rung out the bus grant lines from slot 26 in the system unit to the terminator card in the BA11 and those seem ok. I've checked the NPR jumper is everywhere, or a grant card is present - in all unibus slots, with the exception of slot 2 in the BA11 where the RL11 is. I've tried two or three different M7762's. Hopefully all this paints a clear picture of the problem, and hopefully someone can suggest a course of action that a DEC neophyte like myself can take :) Thanks for any input! Jay West

CRTs, Use them or store them...

by korpela＠ssl.berkeley.edu

I've been thinking about some of my machines that have built in CRTs. I'm wondering how best to maximize the lifetime of the CRTs and the eventual scarcity of replacements. Does a CRT live longest if it is used often, or if it is left unused, or somewhere in between? For most of these machines, it would be possible to route the video signal to an external monitor and disconnect the power from the CRT itself. The question is would that prolong the life of the CRT?

AES Data/Lanier CPU?

by cclist＠sydex.com

I'm working with some very old 8" HS media (doing data recovery) from a Lanier Word processor. It's still pretty early in the process, but it looks as if the AES folks used a 12-bit processor. It's just a wild guess based on some bit patterns I'm seeing. Can anyone verify this? I'm guessing that the year is about 1975/76 or so. Cheers, Chuck

by compoobah＠valleyimplants.com

I don't have the bandwidth to even archive, let alone mirror anything substantial, but might it be a good idea for someone to look into archiving/possibly getting permission to mirror a chunk of TechPubs and the public patches? I'm still looking into converting the IRIX 4 subsytems from IDO 5.3 to runnable setups for IRIX 4.0.5. (since IDO 5.3 is freely available . . .). Does anyone know how to build an inst package on early IRIX (3.3-4.0.5?) No Software Packager, and all the docs talk about using swpkg. . . .

Picked up the prime today. I won't get a chance to have a good look at it until the weekend. It is in excellent condition. It has a system log with every update written down, every service report from prime. Also manuals for software and user guides. Also nothing has been deleted from the 2 hard drives since it left the university. Dan

The Chrislin dual floppy / winchester in the 11/73 should use an AED controller since they OEMed them from us. It simulates a DY and DL. Disturbing thing is I don't see the AED dual wide WINC05 controller card in the backplane.

CV Mod 32/ Sun 3004 CPU questions

by compoobah＠valleyimplants.com

Replaced the tantalum cap in the VME terminator paddle boards on the ComputerVision, fired it up, and I'm getting chasing lights on the diag panel. It does it with all cards, and with only the CPU. Looking at the behavior of a Sun 3/110, it looks like maybe the power-on reset circuit is flakey (3/110 chases once and then goes into selftest patterns, 3004 keeps chasing). Couldn't find this discribed on the Sun3 Zoo webpage. Anyone come across it?

Write-only archives (was: Parking heads on Honeywell DPS6)

by tshoppa＠wmata.com

Jay wrote, after a few bandishments back-and-forth on the "Parking heads" thread: > I am not sure I comprehend the entire > situation behind this thread... so I'm > not making an official request or anything... > just asking a question in the > role of just another listmember... Is this > a discussion that should be > handled off-list? I think that more usefully we could all begin complaining about what we don't like about "write-only" archives. I'm not talking purely about "black-hole" perceptions (e.g. you send it in but nothing ever comes out) but also about a lack of concern for web access, formats friendly to OCR'ing and searchability, etc. Similarly those who scan out-of-date documentation (computers, test equipment, whatever) and sell it on E-bay have a very strong interest in making their archives be poorly searchable and megabyte- large. Recently there's been wars about scanning and downloading old semiconductor datasheets among commercial and semi-commercial entities that want to sell access to that data. I'm not saying that there's no commercial value in access to the data, but the folks who scanned those datasheets and sold scanned datasheets to begin with never really "owned" the IP of the datasheet.

stuff!

by rtellason＠blazenet.net

I went to see this guy today who had a bunch of stuff he wanted to get rid of, and I was looking for scrap. It occurs to me that some of this may perhaps be of some interest... - An assembly that's marked "Mod. A33", it appears to contain a floppy drive (the button is marked 1.44) and there's a square pushbutton and a smaller recessed button (reset?), a liquid crystal display, and a keyswitch. I have two of these. - A tape drive (?) marked "Exabyte Corporation" and "Model HH CTS", I probabl have more than one of these. Pushing open the tape door shows a head in there that bears a slight resemblance to a video head, but smaller. It's got some kind of rails on it and a (single) connector on the back that I dno't recognize, probably for some IBM system. The drive appears to have standard 4-pin power and pin header (50-pin?) going to this. - Printers. I have an Oki 184 that was never removed from the wrapping in the box. Also available to me are going to be some other models, 3?? Oki as well. If you need to print multipart forms these are real workhorses. - Terminals. Since there's been a bunch of talk in here about terminals lately. these I didn't snag today (the car was filled up! :-) but there will be some quantity of Wyse 325 Color and 60 Monochrome terminals, all working I'm told. If there is interest let me know, otherwise these are all going to be scrapped for parts. - "Cooling unit", this is marked "model 052C" and all I can see are a couple of fans and a connector on the other end, appears to be for some kind of IBM racks, I have two of these. - Power supplies, "Lucent Technology C5892B", I have two of these as well. - "Webramp 700", apparently complete with all sorts of stuff in the box. - A docking station and external floppy drive, marked "Toshiba 430", which also has a pile of original software on floppies in the box which appears to include w95. - A box that was "sealed by IBM" until I opened it and apparently containing a "7137 Disk Array Subsystem", complete and certified and such, with some paperwork in a loose-leaf binder, I didn't unpack it any further than that. - Power aupplies and drive assemblies for "IBM 7133 HD Rack Assy" and also the racks, if there's any interest. I believe there is some large number of these, but I haven't had the chance to count things up yet. There's a lot more, and this is going to take multiple more trips for me to end up with all of this stuff before I'll know what I have. If any of it is of interest, please let me know offlist and we'll figure something out. If I don't hear from anybody, I'm just going to get what I can that's usable parts out if it and the rest is history. -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, a critter that can be killed but can't be tamed. --Robert A.

Egads! Just six days 'til VCF.

by evan＠snarc.net

Hey folks. I'm going to be at the VCF East location as of early Friday morning. I expect the exhibitors to start trickling in throughout the afternoon. Anyone who intends to show up as a volunteer will certainly be put to good use! All the show details are on Sellam's site at http://www.vintage.org/2006/east/ ... Since this is the first time I'm running a big event, I gaurantee there will be some mistakes made. Hopefully they'll be minimal. Whatever they may be, please just try to have fun.... Having said that, if anyone's coming from out-of-town, then just ping me (or post to the VCF BBS page or post on our local list at http://groups.yahoo.com/group/midatlanticretro/)... The best part of a VCF isn't the computers, it's seeing your fellow collectors. Also, we some cool prizes. The top prizes are a Replica 1 (Apple 1) kit >from Briel Computers, and a Digi-Comp replica kit as well. Both are exciting so we'll let the best-of-show winner choose one and we'll give the other to a random attendee based on picking a ticket number from a hat. - Evan PS - some people are asking me what happened to the CCN - it'll return with a revamped web site and a different format in May.

Do you object to them being hand drawn? I have used the 9915A and 9825A schematics when repairing my 9915B and my 9825A (ongoing), and they are clear, correct, and readable [1]. Look, Tony is doing a service to the community, *and* he is not making money out of this, so bitching about his insistence on doing things his way is counter productive both for you and for the rest of us. Personally, I would like to thank Tony for his efforts and contributions to this forum. **vp [1] in fact the 9915 schematics are much more readable than the HP supplied diagrams for the HP-85 (which has many similarities to the 9915). In fact any time there was disagreement between the HP prints and Tony's, the hardware agreed with Tony's drawings.

HP 264x terminal deal

by jwest＠classiccmp.org

>From people emailing me off-list, I had interest in about 20-25 terminals. So I went to the ebay seller to work a deal. Apparently there has been a two prong effect - 1) The first few terminals he sold on ebay went quickly and for high dollar, so he now suspects all 50 of them will go for that price.... and 2) many of the people who emailed me off-list about a group purchase apparently also emailed the ebay guy directly (and one of you bought one from him)... so suddenly he thinks there's a huge interest and is now less inclined to make a group purchase deal. So here's the result... I told the guy to go ahead and keep selling them one at a time on ebay, and as soon as he hits the inevitable point after 5 or 6 units that they suddenly stop selling because he's flooded the market, to give me a call. Then I'll ask again if there's interest in a group purchase, but the group will inevitably be much smaller. Jay

Early 1970s PDP stuff for sale

I've decided to reclaim some of the space in my shop, so I've listed some of my excess items on eBay. If anyone is interested, go check it out under user wacarder. I have listed a PDP-8/E with DSD 440 drive and interface card, PDP-11/20, PDP-11/45, PDP-11/34a, an 11/50 front panel, an 11/45 front panel, an ASR-33, a Tektronix vector graphics terminal, some RK05 drives, literature and marketing brochures, and various other items. It was a tough decision to decide to sell these, but most of these are items that I will probably never get around to restoring. My shop had reached maximum capacity and I need the space to do other stuff.

Heathkit EC-1 bootdisk wanted ( sort off..)

by jos.mar＠bluewin.ch

Just kidding about the disk of course . But I now have a mint condition EC-1 and was wondering : - if an operations manual is available, online or as a copy. ( i only have the assembly manual, am willing to pay for the operation manual ) - any source for the plugins ( the plastic bits, R and C are not so much a problem ) ? - Is it just my impression, or is any problem I can tackle with an EC-1 much faster handled with a pocketcalculator or a slide rule? The wiring on my EC1 is lethal : i plan to mount a IEC socket so I can use regular modern-day earthed mains cable. Sacrilege or common sense ? Jos Dreesen

(no subject)

by kyrrin＠bluefeathertech.com

This message is being posted to three groups: Classiccmp, TekScopes, and TestGear. I have available, FREE for LOCAL PICKUP ONLY in Kent, Washington, a nice 3-foot fully-enclosed 19" equipment rack made for HP. It has the maroon-colored 'Hewlett Packard SYSTEMS' logo plate on the front, so I'm assuming it once held stuff relating to the HP System 9xxx series. The thing's on wheels, so it is relatively easy to move. However, you will need at least an SUV or pickup truck to comfortably transport it. I was using it as a computing test stand for many moons, and it is now no longer needed due to equipment consolidation. I'll even throw in a free rack-mounted dot-matrix printer with it (I believe it emulates an Epson FX80 or similar). The FIRST PERSON to drop me an E-mail saying "Yes, I want it! Where do I find you and when can I pick it up?" will get the thing. I will post a note once it is claimed. I'm crunched for storage space, so I need to move it out AS SOON AS POSSIBLE! Please help me to give this nice bit of electronics furniture a good home. If I do not receive any responses by this time Sunday evening (May 7th, 18:40 PDT), I will assume no one wants it and will leave it out in our driveway with a 'FREE!' sign on it (weather permitting -- I'm not going to let it get soaked).

hp 7905/6/20 diagnostic tester

by jwest＠classiccmp.org

Ebay... item 8805060713 Extremely extremely handy for working on 7905/6/20 drives. This one has broken switches but those are fixable. Also includes the head alignment PCA and some of the tools (but it's clearly not the full offline test kit). I don't want to bid on this, I already have two of 'em. But I will bid on it if no one wants it just to save it from being scrapped. If someone has these type of drives, you should buy this. Jay

Cromemco 3101/Beehive B150 score (VT100 bugs)

by swtpc6800＠comcast.net

I had a DEC VT100 that was made around 1980 that would crash when you sent it a certain escape sequence. You would have to power cycle the terminal to recover. Newer units did not have this problem (this was around 1985). When we discovered this we would send this sequence to peoples terminals to see if they crashed. I guess DEC did not get the terminal emulation correct at first.

Parking heads on Honeywell DPS6

by Billy.Pettit＠wdc.com

I'm going to move an old Honeywell DPS6, working. I've in mind to park the heads of the disk ... but how ? The disk unit is from Magnetic Peripherals , model 9448 Internal parts are from CDC , the only code present is BJ7D1-A Anyone know this unit/system ? Thanks Alberto Hah, that brings back memories. The 9448 was code named the Phoenix or cartridge module drive or CMD. Built in Oklahoma City in the early 80's. It's part of the SMD family, sharing the same interface and some of the components, like platters and heads. And used a common Servo Track Writer, the key to their success. For shipping there should be a head locking bar. Lift up the top cover (with power off). On top of the actuator should be a bar with two pins sticking out. There should be a yellow label showing how to twist the bar 90 degrees and it fits into a hole on the carriage and the frame. There was also an instruction sheet stuck inside the top cover with a drawing showing how to install the bar. A lot of the field engineers used to paint the outline of the bar in red for newbies. When new, there was a green card taped to the outer plastic bag with locking and shipping instructions. I don't have any manuals handy - I'm still in Orange County. But if nobody else on the list has any, I'll look on my next trip up to the Bay area - Mother's Day. I think all of my parts are gone, though I did come across a box of heads recently. In the last few months, I've seen the field tester come up several times on eBay. It was called the TB-216. One went for $10 a couple of months ago. These would work on any SMD family drive. Right now there is a Wilson Labs in auction. That also works on any SMD drive, as well as most of the Fujitsu drives. I've seen cartridges on eBay several times, but the idiots open them up to show the platters, thereby hopelessly contaminating them. I used to clean them, but it takes careful patience. The CMD was one of the drives I supported out of OK City for 10 years. I did all the cartridge drives, but mainly the Hawk and Phoenix. I did a long write up on that time recently for an alumni memory book. I should revise it and post it here, provided the list owner doesn't mind 20 pages of ramblings. Incidently, the Lead Design engineer, a media engineer and one of the firmware engineers for the Phoenix work with me here at Western Digital. I shared with them that there still is a Phoenix working somewhere. It delights us all. We spent a lot late nights getting it debugged. Especially contamination issues; removeable media was a Black Art to keep running. Billy

SPI 8606 EPROM burner software?

by owad＠applefritter.com

Does anybody have software or documentation for the SPI 8606 EPROM burner? It's parallel port based. Was there any sort of standard protocol for these, or am I out of luck if I can't find the original software?

Software archiving news from the Computer History Museum

by aek＠bitsavers.org

Just wanted to mention that I've joined the staff of the Computer History Museum as Software Curator. I can be reached at my bitsavers address or my new address at the Museum. I'm hoping to expand the CHM collection by becoming more proactive in trying to locate and archive what early software still survives, which means trying to contact people who might still have old media and listings, especially from the seventies and earlier. http://www.computerhistory.org/about/staff/kossow/

Tektronix 4105, 4205 color graphics terminals for sale/trade

by legalize＠xmission.com

Before I contact the local Tektronix reseller or put these on ebay, I thought I would give the list a chance to get at these. They are all equipment from Telogy, an electronics test and measurement rental equipment company that went out of business. These are units that were electrically tested and calibrated by Telogy in the 1995 time frame. I will guarantee against DOA, but otherwise they are as-is with keyboards. Cosmetically they are in good condition although some units have the typical fading of equipment from the mid 80s. I am willing to trade for terminal servers, serial terminals (particularly ones capable of graphics), or anything interesting that's graphics related. Contact me off-list if you are interested. -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>

HP9817

by ard＠p850ug1.demon.co.uk

A rather strange question : Was there ever an 68020 daughterboard for the HP9817 (aka HP9000/217)? The reason I ask is as follows. The HP9817 (I have one in bits on the bench at the moment) uses a 68010 processor. It's in a PGA pacakge, and is socketed. As the data sheet shows, it's a 10*10 PGA, with 2 rows of pins round the outside, and the 4 internal corner pins (a total of 68 pins). However the socket on the HP9817 board has all 100 contacts fitted. And some of the ones that don't correspond to pins on the 68010 have traces going to them. It appears these are extra intputs to the MMU circuit (in particular to the 'Tag RAM' for virtual memory paging). I am wondering, therefore, if the machine was designed to take a processor with more address lines brought out, the obvious candidate being the 68020. Of corse it would need a daughterboard to rearrange the pinout, but apart from that it may well drop straight in. -tony

UK - laptops available Fwd: Very old `Laptop` - the original??? M20

by classiccmp.org＠irrelevant.fsnet.co.uk

see email below - May be of interest to anybody in the Manchester, UK, area.. Contact the author directly.. PLUS.. this reminds me.. I myself have a DEC Digital laptop available free to anybody who wants it. Model TS30G. Complete with docking station (port replicator, plus 10baseT/10base2 network adapter). Working EXCEPT battery dead, and the screen died last year and showed completely white image, at which point it's not been used since. (The VGA port drove a monitor ok so machine itself is fine, so may just be a connection issue. I don't know...) Collect from Salford (nr central Manchester). Email me for this one.

Need help with Heathkit H89 - loose wire!

by tosteve＠yahoo.com

Hi, I just received a nice Heathkit H89. Great condition, but there's a loose wire on the 16K memory board (one end isn't plugged in anywhere). Hopefully, this is the reason it won't boot. Please check your systems/manuals and let me know where it's supposed to go. It's circled in yellow on this pic: http://members.cox.net/oldcomputerads/pics/wire.jpg Thanks!

Manual for Sigma RQD11/SCSI Controller?

Does anybody have any docs for a Sigma RQD11/SCSI controller?? This is, I really really hope, a QBUS SCSI disk controller that speaks MSCP and emulates a RQDXn. BTW, does anybody know if this card can do TMSCP too, or just disks? Thanks, Bob

kaypro 10 utility and bios source files online

I was poking around one of the two Kaypro 10s that I have. In one of the user spaces there were a number of source files with NLS copyright notices. I did a google search on a few of the names and didn't find any hits, so I uploaded the files to my PC and then put them online. They can be had here: http://www.thebattles.net/oddments/oddments.html
