how good is the data reliability with CD ROM and DVD RAM?

by carlojpisani＠gmail.com

hi yesterday I was shocked by a couple of videos on Youtube where guys pointed out their negative experiences with CD ROM and DVD RAM as media for their own backup. They complained their data completely lost after 5 years of storage in CD ROMs, pointing out that their CDs were perfectly conserved and kept clean without scratches, but all the data is gone lost since the media is unreadable. This is what they said in the video. I have a lot of backup here stored in CDs, and I have recently bought an SCSI DVDRAM unit to create new backups in caddies DVD-RAMs (of 4.2Gbyte each) what is your experience?

Troubleshooting HP 2116B

by cc＠informatik.uni-stuttgart.de

Ok, so I've got the computer almost running now. I now need to fix both sense amplifier cards. One (0..4k) sometimes reads a one for bit 3 after the machine has warmed up. The other (4..8k) has a stuck one for bit 7. Swapping these cards make the errors move to the other core bank respectively. I have the newer cards, 02116-6298, not the older 02115-6001 The latter has CA3028A used as sense amplifiers. My card uses HP 1820-0183 (metal can IC from RCA). I guess that it is also a CA3028A or maybe a CA3053. Can anyone confirm this? Next, the manual on bitsavers (02116-9153_2116B_Vol2_Oct70, and the same as found on the hpmuseum site) not only contains some errors (see my other post about the front panel lamps). It has also some badly scanned pages with parts missing, notably page 5-50 (PDF page 350) lacks the right part of the page. Is there a better scan available? My 1968 copy does not list the 02116-6298. Christian

ABLE, other non DEC boards.

by useddec＠gmail.com

I had a nice talk with an old friend earlier today, and we talked about how some companies were so proud of their products that they never put their name on it. Sometimes a logo, sometimes only a part number. Bitsaver is great- I don't don't know what any of us would do without it. But There are a lot of items that, at least I, can't turn up there or on Google. While looking for the ABLE (ACT) board that Mattis was talking about (and I found it for a list member who has first dibs on it) I came across: Computer Consoles 343d01533 Computer interface Tech -looks like a DZ11 clone CMD CDU-700/T witch I think can be upgraded to a M/T SCSI Unibus Simpact Assoc inc ICP-1600 DPD might have been bought out by CDA Computer design and Applicationd.which might be a subsidiary of Analogic. MM3000, 40199 2mg, FPPC Some of these I've heard of, some not. I have a few hundred DEC compatibles, and I'm tired of going through them. Duel, quad, hex, and 780. A lot of Emulex, dilog, ADAC, Data Translations. Please contact me off list if you are interested in any. Pics would be nice. Thanks, Paul

RK05 spindle pulleys - trade 50Hz vs 60Hz?

by frisbie＠flying-disk.com

Chuck Guzis <cclist at sydex.com> wrote: > In WWII radio equipment, MGs in a unitzed form called > "dynamotors" were used to supply the high-voltage anode voltage > for the tubes. And long after WWII! In the 1960s, I had a Motorola 140D (140 for the power, "D" standing for Dynamoter) mobile radio (6 meter ham band) in my car. Everytime I keyed the mike, the dynamoter would instantly spin up with a loud whine. Such radios were normally housed in the trunk of the car and required heavy wire to carry the 12 volt battery current for the dynamoter. My Monarch 10EE lathe originally came with a big motor-generator to power the variable-speed DC motor. Later versions use thyratrons, while even later ones were solid state, but they all continued to use DC motors. The variable-speed DC drive was very similar (identical?) to elevator drives, known as the Ward-Leonard system. To bring this back to the RK05, someone asked if anyone had a copy of the RK05 IPB. If you still need it, let me know and I'll dig it out. I haven't packed it for my move yet, but the drives are. Alan

DEC power connectors (UNIBUS PDP-11s, mostly)

by jnc＠mercury.lcs.mit.edu

So, it turns out the power connectors (plastic female shell with metal male pins, etc) widely used in UNIBUS PDP-11's (e.g. to provide power to backplanes, etc) are still available, if anyone else wants any. (No doubt some of you already knew this; this is for those, like me, who didn't! :-) The 3-pin ones are used for the remote power on/off cables (used extensively in DEC gear, not just UNIBUS PDP-11's). They are 'Commercial Mate-n-Lok', now made by TE Connectivity, who bought AMP. Here are the current part numbers: 1-480305-0 3-pin female shell 1-480276-0 6-pin female shell 1-480277-0 9-pin female shell 1-480324-0 15-pin female shell 60620-1 14-20AWG male pin The 6- and 15-pin are for the backplane power connecters; the 9-pin were used to power backplanes in older machines (e.g. PDP-11/10). There's also a pin for smaller gauge wires, e.g. for the power control cables, but I don't have the number right here. I have checked, and these do plug into old DEC gear properly. I got mine from Digikey; their page for the line is here: https://www.digikey.com/products/en?FV=ffec0ef5 Go to the bottom, where it says 'Housings', and click on that, and they will all show up. (There are cross-links to the pins when you click on a particular shell.) Noel PS: I'm also tracking down the 8-pin connectors used in the H744/H745/etc regulator 'bricks'; an update on them in a day or so.

HP-2116 front panel lamps

by cc＠informatik.uni-stuttgart.de

Hi, I need to replace several broken lamps from our HP-2116B front panel. The old/original ones are CM-345 or OL-345. This makes sense, they are rated 6V 40mA 10000 hours. BUT: The maintenance manual says something different and is even wrong and inconsistent. HP part number is 2140-0035, description "Lamp, Incadescent, 6.3V, 0.75A" This can't be true. 92*0.75A would be 400W alone for the front panel lights... The manufacturer code is 71744 (Chicago Miniature Lamp Works), mfg part number 1775. That is indeed a 6.3V lamp, but 0.075A (better!). Problem: that is a midget _screw_ base lamp, so wrong socket and only rated for 1000h. The panel and switches need a midget flanged base lamp. Who wrote that manual? Was he drunk? ;-) Christian

Strange third party board in PDP-11/45

by jnc＠mercury.lcs.mit.edu

> From: Mattis Lind > I will take a picture of the boards in more detail so we can figure out > what they are doing later on. Thanks, that would be really useful. > My understanding is that slot 1AB and slot 26 AB is tied to each > other. So if there would be no expansion unibus there should be a M930 > in each of these slots. The same goes for slots 27AB and 28AB. Right, that's my understanding too. There's a diagram in the "PDP-11/45 Maintenance Reference Manual" (October, '73 edition, on pg. 60 - pg. 66 of the PDF), which gives: - slot 1 - UNIBUS A termination - slot 26 - UNIBUS A cable - slot 27 - UNIBUS B cable - slot 28 - UNIBUS B termination and my read is that the slot 26 cable is 'out to any UNIBUS memory, etc', while the slot 27 cable is 'in from the other machine in the dual-processor system'. (There's an interesting discussion in, IIRC, an RH11-AB - the dual-UNIBUS controller for the MASSBUS - tutorial manual which talks about the M9300, which is a terminator which can produce an NPG in response to an NPR; that is used when people want to attach the RH11-AB's second UNIBUS to the UNIBUS B, when there's no CPU on it. So the M9300 would go in slot 27, and the cable out to the RH11 in slot 28.) > I cannot see how a device in slot 26AB or 27AB would be able to > intercept MSYN here. Not _in_ slot 26 or 27, it's in the cable _between_ them! :-) Look at the common case, where UNIBUS A and B are connected: MSYN comes out of the CPU in slot 26, is jumpered across to slot 27 by the M9200, is carried across the backplane to slot 28, and then out (on either a BC11 or an M920). That dual-card thingy that comes with the Cache/45 would allow (if my surmise about what's going on is correct :-) the Cache/45 to place itself _between_ the MYSN out of the CPU (in slot 26) and the 'MSYN out to the rest of the system' (in slot 27). That does mean no separate UNIBUS A and B. But if my supposition as to how the Cache/45 works (that it fills itself by snooping on UNIBUS B in the MS11 controller slot) is correct, UNIBUS A and B would have to be connected together _anyway_, for that to work. (I _can_ imagine how to do it all without joining the two UNIBI together, but I will skip that for now.) Noel

Strange third party board in PDP-11/45

by jnc＠mercury.lcs.mit.edu

> From: Mattis Lind > Here is how it is connected: Thanks for that - very informative! > The sandwiched dual boards are sitting in 27 / 26 AB. The board in 27AB > was empty (quick glance), while the board in 26AB has a few TTL chips > on it. Slot 26AB is the Unibus A slot, Slot 27 AB should be a > terminator on Unibus B. I'm more interested in _what_ the two boards are doing! :-) It seems they must be jumpering UNIBUS A and UNIBUS B together. (Which I didn't expect, but maybe... will have to ponder.) As to what _else_ it is doing, and why it has the cable to the main card... I think that it must intercept MSYN from the processor and only let it pass if there's no hit in the cache. (To explain why it would need to do that... normally with the MS11, there's a static partitioning between FastBus memory and UNIBUS A memory. So when the CPU goes to do a memory cycle, it can put the address out on both the UNIBUS and FastBus, with the certainty that it will only get a reply on one. But with the cache, if there's a hit, it would in theory get a reply on both, which might confuse it. Or if it takes the cache copy, and terminates the UNIBUS cycle, that might confuse the memory.) Or maybe I'm confused, because now that I think about it, UNIBUS A goes straight from the CPU to the UNIBUS A out slot, so the Able board couldn't intercept MSYN? I guess I need to understand the fine details of the UNIBUS A and B stuff, maybe it will make sense at that point. Oh, wait a moment: slot 26 is UNIBUS A out, slot 27 is 'UNIBUS B in', and slot 28 is UNIBUS B 'termination'. (27 is 'in' because when the M9200 is installed in 26/27 to join the two UNIBI together, obviously one has to connect an 'out' to an 'in'... and then 28 is not 'UNIBUS B termination', it's 'UNIBUS out' to the rest of the system. OK, so that works - MSYN coming out of slot 26 is intercepted by the dual double-card, and is only allowed to pass on cache miss. Yeah, that sounds like it should work. > The hex ABLE/ ACT board sits in slot 21 which is the memory controller > board for the MS11. One of two; the other is slot 16. > From: Paul Birkel > I wonder whether this CACHE/45 can coexist with MS11 memory on the > Fastbus itself According to that marketing thing you found, "User may optimize hit ratio by upper/lower limit switch settings", so one would have to configure the Cache/45 to not cache the block that the 'other' MS11 controller thinks it owns... otherwise both might respond to requests for addresses in that range.... :-) Noel

RK05 spindle pulleys - trade 50Hz vs 60Hz?

by mattislind＠gmail.com

Hello! I have two RK05J-AA as part of a system that I guess has been imported used form the US. A DC-10 simulator. The only difference is the pulley, the motor position and a 230 / 115 V jumper inside. Is there anyone in 60Hz land that has the opposite problem and want to trade two spindle pulleys? The good thing for me that I would guess that it possible to use a lathe to get the diameter down to the correct 50Hz diameter. On the other hand going >from 50Hz to 60 Hz is tougher... Then there is a PC05 that has the wrong number of grooves on the motor pulley. Apparently it should be 16 instead of 20. Now in 50Hz land the only difference is that the punch would be slower than it should be. Using a 50Hz punch in 60Hz area might get you into problems, so maybe there is someone here as well that want to do a trade? /Mattis

They are also made by ACT and contain a few TTL chips. If the board is a cache, how does it get filled? It would have to listen to the UNIBUS the memory is on. So I'm guessing that's that those connectors and boards are for. Note that there has to be a signal from FastBus (anyone know the correct capitalization for that?) which tells the CPU if the MS11 has a given address or not (given the way the MS11 can be configured as to size and address), so the cache board could use that line to tell the CPU whether or not the location in question is in the cache.

Just set up the dipswitches and it works automagically at power on. May have docs somewhere, but not sure where... Chris

Looking for Tektronix 4052 R12 Graphics Enhancement ROM Pack and Tektronix 4014 demo files

by mmcgraw74＠gmail.com

I have been recovering dozens of old Tektronix 4050 series tapes and found one with Fast Graphics software for the 4051. This software program jumped into 6800 assembly code and retrieved three bytes per vector from a tape file. Apparently this tape is a duplicate - and it appears that all the files bigger than 1KB have corrupt data. Apparently from the 4014 programmers guide - they had a set of demo picture files including a list with R2-D2. I have found Jos Dreesen's ftp tar file with some 4014 pictures - but I'm looking for an R2-D2 picture file that is on the tape I have but corrupt. I also discovered that Tektronix made a 4052/4054 R12 Graphics Enhancement ROM pack which included the Fast Graphics program in ROM. I would love to find one of those ROM packs - hint/hint :) I did recover one of the shorter picture files of Snoopy - but since I don't have a 4051, I can't run the Fast Graphics program on my 4052 or 4054. One of my buddies threw a C program together to convert the data file into Tek 4050 PRINT statements. I've posted the SNOOPY basic program and screenshots of running it on vcfed in a new thread: http://www.vcfed.org/forum/showthread.php?64726-Tektronix-4051-4052-4052A-4… I'm also still looking for a 4051/4052 Display Board. Mike Haas posted pictures here in Oct 2016 of lots of Tektronix boards including a Display Board - but I don't have any direct contact info for him. Monty

68k development, Avocet Development

by harper＠secureoutcomesinc.com

Greetings to the List - Carlo, I have been using IDE68K out of Norway for about five years and it is excellent: http://home.kpn.nl/pj.fondse/ide68k/ It includes the 68020 instructions such as bit instructions etc - also floating point. I only use the assembler and download S-records to the MVME177-005 boards that I use. I have never found any bugs etc. Best, Jack At 12:46 PM 7/20/2018, Carlo Pisani via cctalk wrote: >hi >does anyone happen to use Avocet Development Tools for m68k? >how good/bad is it? ---------------------------------------------------------------------------------- Jack Harper, President Secure Outcomes Inc 2942 Evergreen Parkway, Suite 300 Evergreen, Colorado 80439 USA 303.670.8375 303.670.3750 (fax) http://www.secureoutcomes.net for Product Info.

how good is the data reliability with CD ROM and DVD RAM?

by dmonnens＠gmail.com

> > I have a lot of backup here stored in CDs, and I have recently bought > an SCSI DVDRAM unit to create new backups in caddies DVD-RAMs (of > 4.2Gbyte each) what is your experience? I recently disposed of a couple hundred DVD and CD backups I'd made. As mentioned in a previous comment, it's simply too impractical to store terabytes of information in 4.7GB segments, plus they take up a LOT of space. HDDs aren't the most reliable, but this is what I use now for that reason. I make sure to keep the previous backup in case something happens. I'll only use optical backups now with the most important data. Backblaze has some interesting stats regarding HDD reliability (they are a data center using thousands of drives running constantly): https://www.backblaze.com/blog/hard-drive-stats-for-q1-2018/ As noted previously, beyond storage conditions, disc longevity depends on the types of dyes used in the discs. Gold is supposed to be best. Early on, they experimented with a wide variety of dye types, and the silver dyes were least reliable, oxidizing in only about 10 years. The thing is, no media format is going to last forever. The only really reliable way of keeping data around is multiple backups and data migration. Basically, for your really important stuff, you'll want a couple of backups, stored in different geographical locations (one local, one on cloud works, too). You'll want to periodically refresh the backups by migrating the data onto fresh media. In the preservation business, the ideal is to refresh after the cost of storage media is 1/2 of the initial investment. So, if you paid $1 a GB for the initial storage media, you'll want to migrate once the new format is $0.50 a GB, and then again when it is $0.25 and so on. This way, the total cost is double what you initially invested. Of course, while the cost per GB might drop steadily, the total amount on a particular media format will increase as well, such that the $150 HDD you bought 5 years ago will have twice the storage for...$150. Definitely open to other suggestions.

DEC uNotes

by jnc＠mercury.lcs.mit.edu

> #30 "PMI on KDJ11-B and MSV11-J" So it turns out there are _two_ uNote sets, with overlapping numbers! (A fact about which I was previously unaware!) I have two PDF files of the collections; micronoteReprints.pdf (the first set), and oemMicronotes.pdf (the second). Note! There's an index to the first set at the back of the second, and it lists 111; but the ToC for the first one only lists 85! But they are in fact all there (and more; the ones there go up through 115). Noel

PDP-11/84 Qbus slots for memory

by jnc＠mercury.lcs.mit.edu

> From: Charles Dickman > an 11/84 with the UNIBUS adapter and PMI memory does not have a Qbus. > ... the KDJ11-B (M8190) bus protocols change when a KTJ11 (UNIBUS > adapter) is present and so what would be expected to be Qbus isn't. Ah, excellent point. Looking at the description of the CPU/UBA adapter in the KDJ11-B User Manual (EK-KDJ1B-UG-001, pp. 7-6 to 7-9), the answer is not certain; it all depends on implementation details on the CPU card which aren't described. E.g. the DMA cycle _might_ work, it all depends on what happens at step 8 when, instead of PBSY being asserted, BSYNC is asserted. The _memory_ will be fine (since in an -11/83, this kind of thing is expected)... but the _CPU_, who knows. Interrupt cycles are more problematic; the assertion of the interrupt level on the BDAL lines (step 1a) will probably pass, but step 6 (assertion of BSACK) may be an issue, since the device will want to assert BRPLY instead (BSACK is not used in a QBUS interrupt), and the CPU may not do the right thing. > I think there was a DEC Micronote that explained the protocol > modifications involved. I don't think so; #30 "PMI on KDJ11-B and MSV11-J" describes the _basic_ PMI, but the interaction with the UBA isn't described there. But the KDJ11-B User Manual has it in some detail. Noel

CoCo OS/9 was: TRS-80 floppy

by chd＠chdickman.com

So what does it take to get OS/9 running on a Radio Shack Color Computer? I have a Color Computer 2 (? 64k and non-chicklet keyboard) and have always wanted to get it working with a disk OS. What do I need? I see a reproduction floppy disk controller on ebay. I would rather skip that and go straight to some kind of sold state memory. Suggestions or pointer to active groups?

Strange third party board in PDP-11/45

by jnc＠mercury.lcs.mit.edu

> We're actually pretty well off, there; we have: > - MS11 Maintenance Manual (DEC-11-HMSAA-D-D) > - MS11 MOS Memory Troubleshooting Guide (DEC-11-HMSTS-A-D) > - MS11-B Engineering Drawings There's also a little bit about the MS11-C (not covered in the documents above) in EK-11045-MM-007. There is a later rev of the MS11 manuals, which does cover the MS11-C; Chuck McManis had both of them: EK-MS11A-MM-006 MS11-A,B,C memory systems maintenance manual EK-MS11A-OP-001 MS11-A,B,C memory systems users's manual but when I contacted him about them a while back, he wasn't sure if he still had them, or if he'd given them to Al K to scan and put up (he was on the road at the time, so couldn't check if he still had them). Al, are they in your queue somewhere? (No rush to do them, if so; I just want to make sure we know where they are.) > If the board is a cache, how does it get filled?

Studying the MS11 Maint Manual, the MS11 controller has access to the full address and data from both the CPU (FastBus) and UNIBUS B. (The FastBus actually has two uni-directional data busses; in and out.) So all that info, this hypothetical cache board can get from the slot it is plugged into (assuming the cache is plugged into one of the controller slots), over its connector pins. The connectors on the back of the card, and two small boards, must be for listening to UNIBUS A (in configurations in which the two UNIBI aren't joined together)? (I'm too lazy to check the slot numbers are see what they actually are.) And there is indeed a signal which the MS11 uses to tell the CPU it has the location the CPU is asking for, so it's theoretically possible to build a cache card that plugs into a FastBus slot. Noel

PDP-11/84 Qbus slots for memory

by mark＠matlockfamily.com

The PDP-11/84 uses the M8190 CPU that is also used in a PDP-11/83. The 11/83 and 11/84 use PMI Memory but the 11/83 also can use Q22 memory. With the 11/83 the position of the memory board (assuming one is using the MSV11-JD or JE) above the CPU uses PMI and below the CPU in the backplane uses Q22. In the 11/84 the CPU is above the MSV11-JE memory but the CPU only uses PMI to talk to memory. diagrams in the Unibus processor handbook indicate that the M8191 Unibus map board only communicates through the PMI bus to both memory and to the CPU. Now my question is, there are 3 Bus slots in the 11/84 above the Unibus map board, would it be possible to put a dual width Q22 I/O board in the second memory slot (not the PMI side of the slot) and have it able to DMA into the MSV11-JE? If so then something like an Emulex UC07 and a SCSI2SD card could make a cost effective disk solution, since Unibus SCSI controllers are so expensive. Mark

Semi-OT: Hitachi Seiki Micon16-II

by jplist2008＠kiwigeek.com

Good arvo all; A family member recently purchased a rather large CNC which uses a Micon16-II system (as well as a Fanuc 15M) to drive it. Unfortunately the battery for the RAM died during storage prior to him getting it and all of the ladder logic is gone. We'd really love to try and find some kind of technical manual for the 16-II, or anything really, to assist in talking with the machine and interrogating it's state. We have a copy of the missing ladder logic in paper form so we're not totally out of luck, but the ability to enter it in segments rather in one 40 hour slog might be nice. If anyone has anything easily sharable we'd very much appreciate the assistance; Thank you. - JP

MOS MCS2529 math chip

by jules.richardson99＠gmail.com

Anyone got pinout/spec information for a MOS MCS2529? In particular, I'm curious about operating voltage. I acquired a Melcor SC-635 calculator yesterday and there seems to be some uncertainty about the output voltage of its (rechargeable) battery pack; some places say 2.4V, i.e. the pack is a pair of 1.2V cells, but others say 9V. 2.4V seems a little low to me for typical logic, but on the other hand I've seen a period ad which says that the external PSU was 9V - and so the rechargeable battery must have been somewhat less than that. cheers Jules

It is speculated that this should be possible, but there are jumpers on the backplane you'd need to pull. See the writeup here: http://gunkies.org/wiki/PDP-11/84#QBUS_slots Noel
