help needed: problem with UNIBUS access on my PDP-11/70

by GOOI＠oce.nl

Reading the replies, not from the screen, but printed, I notice a comment from Tony. This could be important! > Of course you might still have an open NPG jumper on the slot > where the DL11-W is (this card does not short CA1 to CB1). That's an eye-opener for me! I thought that the DL11 would short CA1 to CB1. I guess that some cards that do not use DMA (NPR) short these 2 pins and some *do not*. Since the machine was originally with a remote console, (hard lesson: DO take notes on any action you do to a PDP-11, if you do: make better/more elaborate ones), I think that there was no DL11 in it, but the Unibus serial remote console M8255 was in slot #40. I swapped the M8255 for an M7856. Now, if the M8255 *does* bridge/use NPR ... I will check this evening of course, no matter what pops up! I will do the other tests anyway, and make notes! They will be very useful for future reference. Again, thanks all so far, - Henk.

[CCTECH]74123 woes

by frustum＠pacbell.net

I've been working on trying to get a Sol Helios disk system up and running so I can recover and archive a bunch of disk images. If I can't get it working (I'd really like to get it running for its own sake), I'll get a catweasel card, a conventional 8" disk, and attempt to write my own bit-level decoding software to recover the disks. Anyway, I found and fixed the first problem: one of the satellite circuit boards on the persci had a tantalum cap that had a dead short, taking out the whole +24V power supply (it used a 3-terminal rgulator that detected the problem and cut off power, thus there was no pop nor any telltale burnt traces or wires). I fixed that and things are working somewhat better, but I still can't seek to any track except 0 (via the restore line). After discovering that the schematics I have are for a somewhat different revision of the logic board than I have (doh!), I tracked down the problem to what appears to be a busted 74123 (not LS123, which is slightly different logically). The positive trigger is always high, and the Q-bar output is always low -- that is, the thing looks like it is always triggered despite the fact that there is no edge on the trigger input. I could remove the 74123, replace the resistor and cap and see if that fixes it, but doing it would require a lot more disassembly than I'd like to do without being confident that what I'm seeing really is a problem. Here is where I need advice. I can't find my TTL databook, but it would appear that the trigger inputs are edge triggered, not level triggered, right? Secondly, I haven't done board-level design in more than 10 years, but from what I recall, 99 times out of 100 when I thought I had tracked down a bug to a back chip, it was something else (then again, that was during design, not just working on ostensibly correctly designed boards). I have little experience with the '123 since using one for any timing critical function simply hasn't been kosher for the past 20 years at least. Does anybody know in such a situation like this, is it more likely to be a bad cap or a bad '123, or a short somewhere else on the trace? I can measure the resistance of the R and it is in spec. I've buzzed the circuit to see that the R and C are connected to the pins of the '123. Any other suggestions? Oh, the C is a mylar (I think) with a 5% precision rating stamped on it (100pf). Thanks. ----- Jim Battle == frustum(a)pacbell.net _______________________________________________ cctech mailing list cctech(a)classiccmp.org http://www.classiccmp.org/mailman/listinfo/cctech

Interesting Apple ][ card

by foo＠siconic.com

I found a few interesting cards for the Apple ][ the other day. On it are the markings "Computer Networking Specialists" with a copyright of 1988. It has two whole chips: a 6116 and a PAL. The remaining components are three caps, one which has blown. In fact, of all the cards I found, they all have the same cap blown, in some cases completely obliterated with only the two leads remaining with only a huge swath of soot in the path of the explosion. The cap seems to filter the ground line (it goes from what I believe is the GND pin on the ICs to the ground plane on the card). Each computer with the card had a cable with an RJ-45 connector on one end and a four-pin flat connector on the other protuding from the case. I found other computers without the card but with the cable. The inside end of the cable (with the 4-pin connector) was loose. There is no mating connector on the card for it either. It seems to me that these computers were part of some network scheme, and that these cards possibly held some networking firmware. How the cap blew off the cards is a mystery. I could imagine a power spike coming down the network cable and damaging the card, but like I said, the cable didn't plug directly into the card, and I can't imagine the Apple ][ bus passing along a power surge to the card from the cable. I didn't bother to check any of the Apple's that I pulled the cards from to see if they were working. Anyway, anyone have any knowledge of these?

HP 9133H Configuration switch?

by glenslick＠hotmail.com

Thanks for the config switch info. The 9133H unit I picked up came with the config switch in position 8 and I originally formatted it on the IPC with 8 volumes. Maybe there is a limit on how many volumes the IPC can mount at the same time? Only the first 6 volumes appeared to be mounted automatically. I change the config switch to position 2 and reformatted the drive as 2 volumes and that seems like it might be a better choice. What controls the 256/1024 byte sector size? Is that up to the OS format routine? Is there a CS/80 or SS/80 spec available anywhere to find out more about how these HPIB drives work? Are there any other sources of software for the IPC besides Pete's IPC website? http://www.coho.org/~pete/IPC/integral.html Now that I have a hard drive I don't really have anything interesting to load on it yet. -Glen _________________________________________________________________ Join the world’s largest e-mail service with MSN Hotmail. http://www.hotmail.com

semi-OT

by pat＠purdueriots.com

I've 'rescued' a stack of HM6116LP-3 SRAM's from a circuit board. Apart >from the fact that they're 2Kx8 SRAM's, I haven't been able to find any useful datasheets with both pinouts and timing diagrams for the chips. By any chance, does anyone have one laying around in PDF or that they'd be willing to scan? Minimally, I'd like to know the pinout, basic timing requirements, max clock speed, and data retention voltage. I've also removed an Intel P8291A, which has been just as hard to find information on, anything would be useful. Thanks! -- Pat

Mark-8 *Faints*

by groovelists＠yahoo.com

'Evening all! :) I don't quite know what to say... I suppose I just wanted to tell some people. I'd purchased a computer on ebay listed as, "another VERY EARLY HOMEBREW COMPUTER," a while back for $9.00. It didn't come in a bit over a month... I contacted the owner and waited some more, but had pretty much given up hope on it. It arrived today... I peered about inside... It appears to be a Mark-8. Has at least the same CPU board... I came very close to thumping onto the floor... It has a homebuilt case... it's about sewing machine sized. It has 8 ports of some type, a tape port, a control port. Inside, it has the CPU board, some input type board, some output type board, a board labelled add, and 2 1011 1k memory cards, all attached to a homemade bus. I know it is missing at least a 74xx something chip and the power supply, but... I'll put up pictures of it sometime in the next day or two. Thanks for hearing me rant! :) Oh yes! Thanks, too, to the kindly people who helped me out with the AT&T 3B1 - your help was so very appreciated! :) Andy ___________________ grooveman(a)yahoo.com __________________________________________________ Do You Yahoo!?

[CCTECH]PDP11/23 and Emulex Qbus Controller

by Andreas.Freiherr＠Vishay.com

Pierre, maybe someone else will provide practical experience with the combination QD32 & 11/23, but my first guess would be that bandwidth is not a problem: as long as all devices on the bus obey all the bus specifications, they should be compatible. Was your friend possibly talking about address width (in other words, the number of address lines on the bus)? - There are three variants, with 16, 18, or 22 address lines. Incompatibilities can arise if a *DMA controller* drives *less* address bits than the system actually uses. Non-DMA controllers have no problem because they never address memory themselves. A typical problem of this type is the RXV211 (RX02 floppy disk controller: DMA, 18 address bits) used in a 22 bit system. The problem can be circumvented in driver software by reserving a buffer area in the lower 256kB of main memory. IIRC, older versions of the 11/23 drive 18 address lines, making them capable of using up to 256kB (or 128kW) of memory. Later models (in particular, the 11/23-PLUS) supply all 22 possible address lines, allowing for up to 4MB (2MW) of RAM. I was told several years ago that some /23s can be upgraded by adding a couple of wires (and maybe a handful of bus drivers). The QD32 is no doubt a DMA controller, but I think I know it is 22 bit. Hence, it should be possible to use this controller in any Qbus system. Also IIRC, the QD32 uses MSCP to communicate with its driver software, so it should not even require any special software: a vanilla DU driver would be OK for RT-11 or RSX-11, for example. Anyone have better information to correct me?

help needed: problem with UNIBUS access on my PDP-11/70

Hi Eric. Yes, very strange indeed. The G7273 is placed in slot positions C & D, the correct way. Edward suggested to use the Ohmmeter and check for a very fine disconnect on the etch of the G7273. The etched wire is indeed quite thin, I remember from yesterday.

"modern" CP/M system?

by archer＠topnow.com

Hi, I noted off a link on this list that somebody had implemented a "modern" CP/M SBC based on the Z180 CPU. This, unfortunately, is no longer being made. With the rise of retrocomputing (The new IMSAI and the upcoming Commodore C=1 come to mind), I was wondering if anybody knew of at least a PCB solution with a ready-made CP/M port? Also, are there any good "CP/M internals" books I should be looking out for in the used bookshops? Preferably with enough detail to understand what's needed to do a port? P.S.: I'd love to see CP/M running at 20+ Mhz. :) -- Ross

OT: MECOS frequency device ?

by dwightk.elvey＠amd.com

Hi It might be some kind of bearing failure detection devise. The switches would be to select the frequency to listen at. In a large shop, with a lot of machines running ( like a printing press ), one needs something check each bearing to see if it about to fail. When a bearing is just starting to go bad, it growls. The frequencies mentioned are in the range one would expect for larger bearings. Dwight >From: "Lawrence Walker" <lgwalker(a)mts.net> > > No the LED is in the chassis.

book finds

by carlos_murillo＠epm.net.co

I went to Bogota this weekend and found some good books, including: -VAX Architecture Reference Manual (1987) -Samuel Seely, Electron Tube Circuits, 2nd. Ed., McGraw-Hill (1958). This book is a gem. I saw it once at a library a long time ago and had been looking for it ever since. -A. Khinchin, A Course of Mathematical Analysis, translated from the 3rd. russian ed. and published by Hindustan Publishing Corp., Delhi, India. Not CC related but a real find. I paid less than $3 for all three books. Something to calm the collecting itch for a few days :-) . -------------------------------------------------------------- Carlos E.

help needed: problem with UNIBUS access on my PDP-11/70

by GOOI＠oce.nl

Thanks all for the many good replies. This is what I have done so far. At the end is what I did *not* do (yet). At first, I kept the 3 MASSBUS interfaces installed. They were in the machine, so I did not suspect them. - I installed the H744 in the upper PSU. All +5, -15 and +15 V. all look OK, measured with a Fluke. I am not yet in the stage to pull out the scope and do "difficult" things. - I will check the jumper on the M8132. Normally I make notes of steps I do on my machines, but Murphy is still alive. I cleaned the 11/70 with remote console *completely*. Got the 11/70 with full console 2 weeks later. Since I am keeping one and donate the other 11/70 to a museum, I did not want to clean the second 11/70 also. The guy at the museum may do his share of this bargain. So I swapped the consoles, and (AFAIK) the boards. That is the problem: I can not remember that last action. Perhaps I did not swap all CPU boards between the 2 machines and only moved the FP option boards (and forgot/didn't know about the H744 to supply +5V to slots 2-3-4-5). As Tom wrote, the 11/40 indeed needs on 2 boards (IIRC) change of jumpers for FIS/EIS (or was it MMU)? - I kept a G727 in the 4th MASSBUS slot at the correct position. Removed from all not used UNIBUS slots the G727 and replaced them with G7273 dual-height grant cards. Result is still NOK: hung on console address access (read/write). - Removed the other 3 MASSBUS interfaces. Put a G727 instead of the M8153, according to FMPS. Hung remains. - The "golden" tip from Tony. Removed the M9302. No more hung! XBUF status shows octal 200 (indicating TX buffer empty, ready to receive byte to transmit). Store octal 71 in the TX buffer and a "9" appears on the VT320!! Basically, I have a complete working machine, but ... - Put an M930 as terminator in the 11/70. Still all is fine. - Put an onther M9302 (from the working 11/34C) in the 11/70. The hung is back. - Put the M930 back in again. LOADed address 17765744 (from the M9312 manual) and pressed START. All LEDs flicker for a few seconds, then all go off, except ADDRESS LED #2, so address 00000004. I guess this is a TRAP because the boot device was not accessible. Makes sense, there are no devices connected! What I did not do. - Remove the RX11 (non-DMA) RX01 interface and replace it with an RX211 (DMA) RX02 interface to see how that affects the NPR line. - Did not check the ACLO and DCLO signals. Since I can run "a small program", memory interconnections, the memory and the CPU itself have no apparent problem. - Did not try to read the ROM on the M9312 with the M9302 installed. Will do that this evening (probably). The weekend was shorter than I expected it to be. As usual ... I did read the CPU registers (IIRC), but check on that again. - I will read the M9312 manual again. The numbers Johnny writes about sound familiar. However, it this moment I do not have any disks (RX,RL) connected. Thanks again so far, - Henk.

Introduction and greetings!

by archer＠topnow.com

Hi, This is Ross -- just saying hello to the group. I'm a software engineer by profession, but an 8-bit hacker by avocation. While I'm especially interested in 6502 hardware, Z80, 8080, and even 1802 stuff is also of keen interest. It's partly nostalgia, and partly that these old systems are understandable by mere mortals with a reasonable amount of effort. I love how one could get a book or two and know everything you need to program one of those old machines, vs. today when the number of standards and interfaces has gone spinning out of control of the individual hobbyist, at which point it becomes more "work" than "play". I still think studying those older micros is a perfect way to truly understand the principles involved in computing without all the distractions of multi-level caching, out-of-order execution, branch prediction, branch delay slots, etc. etc. Once grounded in those basic principles, you can build the rest. IMHO. Currently, my stable of hardware includes: 1) A nearly pristine KIM-1, currently serving as a 24-hour clock. I posted some "ready-to run" software and scans of user manuals, and a few songs played by KIM, etc. at http://www.learnmicros.com. 2) Commodore 128. I like this because it can be used to learn CP/M and Z80 ML as well as hack at the '02 and C64. :) 3) Apple IIe. Nice accessible hardware to hack with. 4) TI99/4A. Anyone want for the cost of shipping? I just can't fit this one into my collection very well, and there are only a few cartridges for it. 5) Daryl Rictor's SBC2. I got that SBC tweaked to run at the blazing speed of 6 Mhz running a variant of BASIC called EHBASIC. This is my current timesink. A 6502 at 6Mhz is not too shabby. :) Anyways, holas again to the group and hope you all are having great summers. -- Ross

Do old Calculators count as Classic Computers?

by rhudson＠cnonline.net

>from the I-thought-it-was-programmable department: Anyone know what the K key does on my Texas Insturments SR-40 (I'ts got an LED display, it 'gots' to be old!) I have googled, I found lots of stuff on a signal processor (?) with that name, and a few pages that show the calculator, and give a date range for Mfg. but nothing that describes the keyboard. I tried pressing the K key in several cases 5 sin = 5 K sin 543 = 54K3 (K does not end a number ) tis a puzzlement. : ^ )

SparcStation 1 RAM question

by doc＠mdrconsult.com

Hi, all. Will a Sparcstation 1 run OK with mixed parity & non-parity SIMMs? Each bank is a matched set, but I have 8 parity sticks and 8 non-parity. The "test-memory" diagnostic from the boot monitor seems not to mind, but I thought I ought to ask anyhow. Doc

HP 9133H Configuration switch?

by glenslick＠hotmail.com

Anyone know what the 10 position Configuration switch does on the back of an HP 9133H drive unit? I tried some google searching for info on this drive unit and didn't come up with much. I just picked up one of these drive units at a surplus store and hooked it up to my HP Integral PC. It looks like it shows up as 9 different devices, where D001 is the floppy and D000, D100, ..., D700 are 8 disk partitions. Can you configure the drive so that it shows up as fewer and larger partitions? -Glen _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx

"Rare" DEC finds in Montreal...?

by claudew＠videotron.ca

Hi all... Space is getting to be a problem here and I am mostly into home/hobby micros >from the 70s and 80s (thats what I grew up with) but could not pass this up...since I hear so many discussions about DEC on this newsgroup... I dont think the models and equipement are rare, but getting any kinda DEC stuff up here in Montreal, for free, in perfect cosmetic and working condition with tons of software is rare...for me anyways...I guess the trick was tracking down some older ex DEC employees around here... Vaxstation 4000 VLC Vaxstation 4000 - 60 Storage Expansion with tape drive DEC mouse VRT19-HA monitor and a few cables... No missing parts, no cracks, no broken doors... I only see occasionnal DEC stuff at a scrap/surplus computer place here and its always in very bad shape...and owner always asks for $s in the "what???" range.... I dont really know this equipement...but fun to explore I guess... And the guys says : oh!....I have more DEC...way more at one of my houses if you are interested...! I guess I might be...

Star Trek Re: Classic BASIC Games

by ajw＠best.com

I tried running the MDS version of Super Star Trek (from your link). Unfortunately, it uses the DEF function, which is not currently supported in my interpreter (On the TRS-80, which is the version of BASIC I used for the spec, DEF is a "DISK BASIC" function, not in the standard MS BASIC Level 2. But, I've added several DISK BASIC statements, and DEF is the next on my list to add, one of these days. The version of Super Star Trek I included in my collection is from Creative Computing, and doesn't use the DEF statement. There is also a great version of Star Trek that uses some TRS-80 graphics that will work, on trs-80.com in the model I software section. Here is a history of Super Star Trek as noted by David Ahl (editor of Creative Computing): ---- Many versions if Star Trek have been kicking around various college campuses since the late sixties. I recall playing one at Carnegie-Mellon UNiv. in 1967 or 1968, and a very different one at Berkeley. However, these were a far cry fron the one written by Mike Mayfield of Centerline Engineering and/or Custom Data. This was written for an HP2000C and completed in October 1972. It became the "standard" Star Trek in February 1973 when it was put in the HP contributed program library and onto a number of HP Data Center machines. In the summer of 1973, I converted the HP version to BASIC-PLUS for DEC's RSTS-11 compiler and added a few bits and pieces while I was at it. Mary Cole at DEC contributed enormously to this task too. Later that year I published it under the name SPACWAR (Space War - in retrospect, an incorrect name) in my book 101 Basic Computer Games. It is difficult today to find an interactive computer installation that does not have one of these versions of Star Trek available. --- - Anthony ----- Play classic basic games: http://www.awsoftware.org

Classic BASIC Games

by ajw＠best.com

Howdy! If you are interested in classic BASIC games running on Windows, check out my collection of classic BASIC games! Each game included in this collection is an original, un-cut classic game from the '70s and early '80s. Although these versions are TRS-80 versions, they are very similar, if not identical, to versions for other computers of the day (Apple II, PDP-11, etc.) These games run as native windows apps via a Microsoft Level 2 BASIC compatible interpreter that I wrote. The interpreter will run original tokenized or ASCII programs. Included in the package are classic games, like Hamurabi, Elisa, Star Trek, etc. http://www.awsoftware.org - Anthony

OT: MECOS frequency device ?

by lgwalker＠mts.net

Likely way off topic, but I acquired some sort of frequency device in an auction junk box. It's a well machined device made by MECOS, made in W.Germant. It's about 2" square by 1/2" powered by a Li. battery and has micro-switches labelled 3 hz, 7.8 hz, 14.0 hz and a small led that flashes at the selected frequency. Anyone have any idea what it might be ? A search turned up that MECOS makes Active Magnetic Bearings and control boards and programs. Lawrence lgwalker(a)mts.net bigwalk_ca(a)yahoo.com

IBM PC 5150 rescue in Central Indiana

by erd_6502＠yahoo.com

I was contacted by a fellow about a 64K 5150 that seems to have the older 16K-64K motherboard, with all the trimmings... his messages follow. Contact him directly, not me. He is moving and needs this picked up by this weekend or it goes to Goodwill or the dumpster. I _have_ checked with him. Pick-up is OK. First come, first served. -ethan --- JESMason(a)aol.com I have an original IBM-PC (64K, 2-drive, cassette port model hardwired with serial # sticker deteriorated ending in 9248(?) complete with an Epson FX85 printer, Zenith monitor (the IBM monitor expired 2 months after purchase) and software including Wordstar, VisiCalc, DOS1.1, and all manuals in original binders and cases and most original IBM software diskettes. I am moving in one week (7/16) and just want to put this with someone who would appreciate its uniqueness and get some pleasure from it. It worked when stored but I have not tested it. The only repair was a new power supply shortly before I replaced it -- about 1982-ish. Shipping costs paid by buyer would be about $200 (those suckers were heavy!) paid to my PayPal account (JESMason) for your protection. If this is not for you, perhaps you know of someone who would be interested. ~~> Scott Mason 317-580-1950 Indianapolis --- I'm not an expert but I believe it meets your need. I know it would not expand beyond 64K (I had a choice of 16K, 32K, or 64K and the only way to expand it was a cassette. And mine cost $10,900 new. 8-) If you can pick it up by this Sunday 7/14, great. Otherwise it goes to Goodwill on Monday. My only interest is that someone enjoy it. I shoved it into the attic and forgot about it until now. The address is: 10719 Braewick Drive, Carmel, IN 46033 317-580-1950 __________________________________________________ Do You Yahoo!?

VAX 11/750 boot probs - help appreciated

by msell＠ontimesupport.com

Guys, I've finished restoring a VAX 11/750 back to good physical condition, and have (by trial and error) selected a boardset that "appears" to be operating correctly as far as I can tell. The problem I'm having deals with booting from the integral TU-58. When the machine starts up (set to halt on boot) - it presents the proper message: 00000000 16 Running the microdiagnostics gives no errors: %% 00000000 01 However, attempting to boot from the TU-58 (B DDA0) results in the following message: FFFFFFFE 05 The strange thing is that the diagnostic LED on the TU-58 controller does not respond as I would think it should. From what I understand of it's operation, the diag LED on the controller is supposed to blink once when power is applied, pause while internal controller diagnostics are performed, and the light constantly when diagnostics pass (on the controller). On mine, the LED blinks, and then stays unlit. But, if I disconnect P2 (the communications cable to the 750 CPU), this controller diag LED operates as expected. This same behavior is observed if I remove L0004 in slot 4, then the TU-58 controller behaves as I have read it should. This machine did have the remote diagnostics option installed, and I had to move the TU-58 and console communication connectors to the alternate position on the backplane as if the remote diagnostics option was not installed. If I put these connectors back in the original positions (as if the remote diag option was installed), the TU-58 controller passes diagnostics, but the console does not respond (duh....). Could the L0004 be sending a garbled request to the TU-58 controller? I have tried two different L0004 boards, both exhibit the same problem. I have tried different memory controllers to test the boot PROMs, and swapped (and removed!) the L0008s, etc. Erf. Any ideas? From what I understand of the installation of the remote diagnostics module, the only modifications required were the installation of the board (L0006), moving the TU-58 and console comm plugs to the left row of backplane pins, and the installation of the modem. Could I be missing another modification that needs to be "undone" ? I really appreciate any hints or guidance.

NorPak???

by rigdonj＠cfl.rr.com

Today I picked up some modules marked with the Square D logo and the name NorPak on them along with Class 8853 and Type TO-7. The modules are about 2 1/2" square and about 2" high and have two symbols of Op_Amps on them along with three ten contact terminal strips. The terminals have holes for some kind of small pins to plug into them. Next to the Op-Amp symbols they're marked "250 Ma DC Amplifier (2)". They look like plug-in modules for some kind of electronic training device. Is anyone familar with these?? Google didn't turn up anything. Joe

DEC 350

by lgwalker＠mts.net

On a run to the local dump I came up with a DEC 350. It is missing the center HD. My buddy who spotted it and pulled it out swore it had the central section before we lugged it down from a pile of scrap. He gave me the model so it must have been there. I am debating whether it's worth the effort to go back and find it or is it not too difficult to replace. It has 4cards in the cage and the 2 daughter boards. lawrence lgwalker(a)mts.net bigwalk_ca(a)yahoo.com

help needed: problem with UNIBUS access on my PDP-11/70

by GOOI＠oce.nl

I measured the voltages at the connected on the backplane yesterday. They are all fine, but ... the +5V on P2, pins #5 and #6, is 0.6V. This +5V powers the slots 2-3-4-5 where the floating point sits. Since I swapped all boards from my 11/70 with remote console with the boards from the 11/70 with full console I suspected that the remote console 1/70 had the FP option and the other did not. Checking ... yes indeed! To my shame I see that the H744 in position A is in the "remote-70" and position A in the "console-70" is empty! Easy to say that FP would not work! I moved the H744 from the remote-70 to the console-70 and checked the voltages again. Now, the pins #5 and #6 on P2 also show 4,98 V. Unfortunately, this installed PSU does not solve the problem. I still have the PAUSE led on with any access to 1777756x (read/write). My new question. When you have an 11/70 without the floating point boards and you want to install the FP option, you do the following things. - carefully slide the 4 FP boards in the correct position, in the slots 2-3-4-5. - install an H744 in the upper power supply, position A (nearest to the transformer compartment) and connect it to P9. - is there something else you shuld do ?

help needed: problem with UNIBUS access on my PDP-11/70

As Andreas says, when the washing machine runs, turning on any big PDP-11 blows the fuse. I have to reset all clock radios and the clock on the microwave oven. I definitely will check the DCLO and ACLO signals! I will use the scope also to check the +5V lines for any ripple.

To clear things on the question from Tony, when I push the START button the PAUSE led goes on immediately. I will not get that far that I can try to access to the DL11-W again. I will swap the M9302 at the end of the backplane (it is there, I just forgot to mention it) with an M930. All slots that need a grant card according to the Field Maintenance Print Set (FMPS) have one installed. The FMPS shows G727 flip chips for one slot of the 4 slots per MASSBUS interface that not installed, and all UNIBUS slots at the end of the backplane. I had the same experience as Ethan did. When I removed the TU80 interface from my 11/34C the system hung. I inserted a double grant card G7273 and all was fine again. Have I nice weekend, - Henk.

Ectomic Group ASPS Process Controller?

by foo＠siconic.com

Some guy contacted me wanting information about a series of equipment that controlled a "huge circular saw used for cutting huge quantities of wood". I'm looking for any information on the following: ASPS Process Controller ASPS Executive Controller ASPS Schedule Controller ASPS Monitor Controller The labels he found indicate it was made by Ectomic Group out of Arlington, Texas. Along with these large racks are two Teletype ASR-33's. Apparently this is from the 1970s. My guess is that this is a process controller that may well be based on some mini-computer like a DEC or other mini-computer of the day. The guy who relayed this information to me is basically computer illiterate, so he probably can't be of any help to identify anything beyond what he already gave me. He's located near St. Louis in Pacific, Missouri. He is tasked by the owner of the equipment with trying to sell it to get the highest amount possible for it. I told him at best, if anything, to expect someone to come and take it away at their cost. He also has a Wang computer that is the "size of a dishwasher" that is separate from the lot above. Merle? (Sorry, no model number.) If someone thinks these things are worth saving, let me know and I'll put you in touch. My guess is that the guy will try to extract some cash from you for it, but that's up for any potential rescuer to deal with. An offer of scrap value should do it.

Conquest???

by Antonio.Carlini＠riverstonenet.com

I have a vague recollection of a game that might fit the bill - assuming it's sources still bore traces of having travelled through RSX at some stage. I'll have to see if I still have my old tapes kicking around the attic - it's about time I migrated them all to CD anyway. Antonio

Time for a reality check now! The machine runs! DCLO and ACLO is not the problem. What is the problem is a total hang when trying to access the DL11. The question is if he can access the I/O page at all. I haven't heard any confirmation if it is possible to read from the bootstrap code locations. They are also in the I/O page, and thus is a very interesting test. PAUSE goes on when you start boot, but that don't tell us enough. The boot roms don't access the console, so we atleast know that the DL11 isn't the only problem. I suspect you have problems accessing the I/O page in general. But can you access the MMU registers, and other processor registers at the I/O page? And still, NPR might be the problem. If I remember correctly, a broken NPR might show up just like this. The same goes for the BG lines. Remove and reinsert the grant cards, check the I/O page more. You have access to memory, and can run programs, so let's skip the stuff that we know is working correctly.

Amiga 1000

by doc＠mdrconsult.com

Well, I held off for a year and a half, but when the A1000 hit $5 I couldn't help it. I bought it. Now all I need is a keyboard, joystick, and a clue, none of which were available at Goodwill. I do have a display, thanks to Bill Bradford. Will a 1541 or 1571 external floppy be a good addition? Which? ISTR that there's no reasonable hope of genning up a boot floppy on a PC or Mac, right? So I need to find someone to dupe disks to get started? Or <shudder> pay for them? Anybody have a pile of spare keyboards & mice? Doc

I hope that I do not have to dig in that deep, but I have a quad and a double sized extender board and a good Tektronix 465. If building the KM11 was the problem, I did not have a problem.

i432

by dwightk.elvey＠amd.com

Hi It looks like I made a nice find. I bought an Intel 200 series expansion box, mainly because it had the two card set for the Intel double density. (Intel's double density is not compatible with others.) There was another board in the chassis that I didn't even look at much. I just assumed it was some ICE board without the dongle so I didn't give it much thought. I then noticed that the extraction ear said 432IP. Looking closer, it seems to be a 432 card with a 432 chip. It is a 432/602 board. I nice find. Now, I know that information on these are rare but I thought I'd ask, does anyone have any of the software to run one of these? Thanks Dwight

KM-11 (was RE: help needed: problem with UNIBUS access on my PDP-11/70)

by GOOI＠oce.nl

Hi all. > BTW, how much did that KM-11 replica PCB cost? I wish I > could find hobby-level PCB vendors that _could_ do > gold fingers, but for as much as that card would be used, I did a quick check in my cards stock. I guess that the simple M105 address selected is a cheap candidate to get a new life as KM11. Just remove the few parts and, to be sure there are no interconnections, cut the trace a bit after the fingers. Then solder a flat cable to the traces that are used for the KM11. ** Do not extend the length of the flat cable too long! Stray capacitance between the wires can induce a voltage in the wire next to it. I had that problem a few years ago. The thing worked nice, but after a few months it died on me and I could not figure out what went wrong at first. With the oscilloscope the problems became visible: due to crosstalk/induction between the wires, the signal voltage on some wires went negative, more than -0.6 Volts. TTL circuits really hate that! - Henk. (with a busy weekend ahead...)

Anyone Care About RT-11

by jhfinepw4z＠compsys.to

In regard to the Freeware CDs for RSX-11 and RT-11 I have now finished the verification tasks that I feel are needed to ensure that I am producing correct images. I will be making some copies of the CD images from: ftp://ftp.trailing-edge.com/pub/cd-images/ http://www.classiccmp.org/PDP-11/RT-11/ http://www.classiccmp.org/PDP-11/RSX-11/ At this point, the only thing that I still want to do is to have a label which accurately reflects the contents. Obviously, the same label that Tim Shoppa used would be best. Failing that, at least the same words. Since I already have my own copy of the RT-11 CD, that is NOT why I am sending this e-mail. Does anyone on this list know where I might obtain a copy of the RSX-11 CD labels? If I have not been able to obtain a copy of the RSX-11 CD labels by the end of July, then I will just do the best I can! For those users who receive a personal copy of this e-mail, you are already on my list. I will send you a mailing address when I am ready to burn the CDs. Sincerely yours, Jerome Fine -- If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.

help needed: problem with UNIBUS access on my PDP-11/70

by GOOI＠oce.nl

Hi all. I am having trouble with my 11/70 because it works only partial. Since things are quiet on the list, I have something to ask. It is a long story, but as said on the list this week, the more info you give, the less not relevant suggestions are typed. First the description of the machine. The machine has only all CPU boards (with FP), the DL11-W and 3 MASSBUSS interfaces. The fourth MASSBUS interface has in the correct slot a G727. All other UNIBUS slots have a G727 in the card position D. The MOS memory box is also connected to the CPU. This is what I have done so far. When I turn on the machine everything "looks" fine. With the switch ENABLE/HALT on HALT and pressing START, the machine sort of resets. With the panel I can dump data in the MOS memory at address 00000000. I did this also at 00001000 and 00010000. It 'works' and when I read the contents back from those addresses, it is the correct data. So, my first conclusion is that (part of) the CPU is OK and that the address and data path to the MOS memory and the MOS memory box itself are all OK as well. Here is the part that worries me. In slot #40 (IIRC) is the DL11-W (M7856) console interface. I am trying to write to the transmit buffer address (XBUF - 17777566). I set the knobs on the 11/70 console to "CONS PHY" and "DATA REGISTER" so that the address on the switches is the real physical address and the data on the switches is what I want to store. After the reset of the machine (HALT/START) I set the switches to 17777566, and press LOAD ADRS. On the ADDRESS leds appears 17777566. Now, I set the switches to 00000071 (should give a "9" on the VT220). When I toggle the DEP button, the PAUSE led goes on. According to the handbook that means the the CPU tries to finish the instruction as far as possible and then waits for an event to finish. The event could be (I assume) an interrupt or, in this case, access to the UNIBUS section. Next test was checking the DL11-W interface. First I switched on my 11/34C. With address 165020/START, I get the dump of the registers on the VT102. So, I mad sure that the M7856 in the 11/34C is OK. Now, I swapped the M7856 of the 11/70 with the M7856 of the 11/34C. First, I started the 11/34C again. I get the register dump on the screen. So, the M7856 from the 11/70 was OK. Just to make sure I tried the 11/70 again (with M7856 of the 34C), but I get the same result: PAUSE led goes on. Yesterday, I had a long conversation on the phone with Edward. We talk about all kind of (PDP-11) things, and also the 11/70 problem. One suggestion was that the UNIBUS map is not yet initialised, and that would cause the UNIBUS accesses to fail. My guess is that when the console panel knob is set to "CONS PHY", I have full access to all addresses without any mapping taking place. Is this correct? Anyway, to test the "UNIBUS map initialisation" theory, I read the M9312 bootstrap manual. The 11/70 (and 11/60) have a different PROM that stores the diagnostics. The 11/04--11/55 PROM also contains a console monitor, but the 60 and 70 PROM only has diagnostics. The manuals says to load address 17765744, then set the switches 8-0 to the device code and then press START. I checked the M9312 to look at the diag PROM. According the M9312 manual the PROM code must be 248F1 (IIRC) for the 11/04-11/55, and 233F1 for the 11/60-11/70. My M9312 has a PROM with code 616F1. Is that a new type for the 11/70? The M9312 is the card that was in the 11/70 when I got it, and another 11/70 (with remote console) that I have has the same PROM. Edward's 11/70's (he has also 2) one has a 233F1, the other has a 616F1. So, I did that test, but the PAUSE led goes on again. Trying to boot from an RX01 should need at least the RX11 card in a UNIBUS slot ... I did that, so I put the M7846 in slot 41 (IIRC), next to the DL11-W. Tried the test again: 17765744 - LOAD ADRS - set the device code on switches 8 to 0 - START. Alas, PAUSE on again. What puzzles me is the "device code" you must set on the 9 least significant switches. I have set that to 170 as that are the LSB's of the start address fro the bootstrap of the RX11. Is that correct? Come to think of the good advice from Tony: I will check the power supply voltages this evening. Especially the one that supplies the cards that deal with the UNIBUS section ... tnx for reading all this, and TIA for all responses, - Henk.

Hi I'm not sure if this is old enough. I have a sparc 5 that has stopped booting. I'm not sure if it is the nvram that has failed or the disk. Does anyone know the full name of the normal internal disk drive? I'd like to compare it with the one it says it is trying to boot from. Dwight

Help with sparc 5

by dwightk.elvey＠amd.com

Hi Dan I get a 'boot device not ready' message. I'll have to look to see exactly what the device is but I do remember it does include the sd@3,0. I guess it is just a bad drive. I'm the only one to look into it so I don't think it is an issue of the wrong slot. I'll have to see if there is any F-code diagnostics for the disk. Some times there is something there that can help check. It means spending a couple of hours hacking through the open boot code. The disk spins up and makes the bleep-bleep sounds that they normally do.

I'd live, but I'm much happier having it gone. > Anyone who can filter on subject *should* be able to filter on another > header; anyone who can't filter probably wants to get the digest version > anyway. NOPE! Due to a bug in Samsung Contact (successor to the hated OpenMail from HP), I now have to have all my classiccmp/cctalk/cctech mail forward from our Samsung Contact system to a system that does POP correctly. But, that forwarding screws up the sender/reply info (from Pegasus's viewpoint, anyway). The short of it is: if it isn't in the subject line, or from the simple "From" line (e.g., john(a)foo.com), I can't usefully filter on it now. I.e.: I *WANT* the CCTALK/CCTECH in the header!

Hung 11/70

by bqt＠update.uu.se

A suggestion is to add info-pdp11 to these kind of questions, since some of us don't really have the energy to plow through all of cctalk... :-) Anyhow, just like some others have suggested, it definitely sounds like a hung Unibus. Check NRP jumpers on all the slots. Remove the massbus interfaces. See if you can access anything in the I/O page. Those are the first things I'd try. Also, the 11/70 have different regulators for different parts of the backplane, and one regulator us just for the Unibus slots at the end. Check that regulator as well. Also, I hope you have a good terminator card. :-) Johnny Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt(a)update.uu.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.

ANN: Altair32 v.2.3 released / 680b Progress

by RCini＠congressfinancial.com

Hello, all: I wanted to drop the group a note to announce that version 2.3 of the Altair32 emulator was released last night. There were a few minor bug fixes and the addition of source-level debugging. Again, I would like to thank Jim Battle for graciously letting me borrow his Sol debugger for the Altair32 project. The main Web site for the Altair32 is: http://highgate.comm.sfu.ca/~rcini/classiccmp/Altair32.htm I also wanted to mention that the Altair 680b emulation project is progressing nicely. I have a few minor problems with the operation of the front panel that need to be fixed. Once that's done, I can start testing it with live 6800 code, including the 680b Monitor. That project page is: http://highgate.comm.sfu.ca/~rcini/classiccmp/Altair680.htm Enjoy! Rich

I have an H-27 that is using a Shugart drive as a replacement for a bad Memorex. I hope to pick the drives up around X-Mas. I've sent Bill a non-refundable "storgae fee" (read bribe) to keep them until then. The H-27 doesn't include the controller (needed!), so I'm not sure the drives would be of much use to you.

AV 4300 RAM?

Hello all, I just got a DG AViiON AV4300 from a helpful list member (thanks dan!), and I need to find RAM for it. Now, it appears that it would take PC-ish 72pin SIMMs -- is this true? If so, what are the details? ECC? Parity? Actually some crazy DG RAM? I'd love to get this machine running -- it even has a "monday and wednesday" backup tape still in the drive :) - Dan Wright (dtwright(a)uiuc.edu) (http://www.uiuc.edu/~dtwright) -] ------------------------------ [-] -------------------------------- [- ``Weave a circle round him thrice, / And close your eyes with holy dread, For he on honeydew hath fed, / and drunk the milk of Paradise.''
