Hi. Got a PDP-11/34 today. It came with a RK05, a Tektronix 4012 + hard copy unit and a Western Peripherals TC-130 9 track tape controller. Unfortunately I had to leave the actual tape drive behind. No space left on /dev/car and way to heavy for my herniated intervertebral disk... The tape drive was some kind of Cipher 800/1600 BPI drive. There was printed "MOD NO 0920640-1250U" on it. I couldn't find anything usefull on the net with this information. Now the problem: I own a Cipher 880 9 track tape with Pertec interface. It works well on my QBus VAXen and the PDP-11/73. So I am used to the 2 x 50 pin cables / connectors found along the Pertec interface. But the TC-130 tape controller has one 50 pin cable labeled "control", a 26 pin cable labeled "read" and a 26 pin cable labeled "write". There are two connector adapters to adapt the 26 pin cables to 36 pin connectors. I found the TC-130 manual on bitsavers. From a quick look at the signal names the interface of the TC-130 is not Pertec. But what else? Is there any way to connect the TC-130 to my Cipher 880? -- \end{Jochen} \ref{http://www.unixag-kl.fh-kl.de/~jkunz/}

MINC-11 boot problems

by james＠machineroom.info

Hi all, I obtained a MINC-11 from Adrians DEC emporium(aka garage) in Cambridge last year (http://www.binarydinosaurs.co.uk/museum/digital/minc/index.php). I've finally got around to taking a look and it appears to be complete and original with a /03 CPU. Taken all the cards out and given it a good clean. Checked for any odd washers etc. in the backplane. Removed the power supply (H786), hooked up to a pair of hard drives as a dummy load and tested. Nothing. Normally at this point I'd scrap it and hook up a PC PSU but I've been reading this group too long and have been persuaded by Tonys component level repair arguments so I got stuck in :) Tracked it down to one of a pair of 1N4004s connected in series after the 7912 12V start-up regulator. So, I now have healthy 5V & 12V supplies and these seem to be stable for a long time with all the cards in place. But - it's not booting. The diag LEDs on the BDV11-YA constantly read 1001 from power on (I'm assuming that on=1). The only table of diag codes that I could find lists 1001 as "DECnet message received" which I believe to be bogus since I don't have any DECnet cards (I'm also wondering if the MINC has different diag codes?). So I started digging further and found that BDCOK H is ~1.7V and BPOK H is ~2V. Now, I believe that these signals are generated directly from the PSU, specifically the power monitor board that calls them DC L and AC L. My assumption is that these should both be at 5V in a healthy system since they are active high - correct? Unlike a regular LSI11 the MINC doesn't have any front panel buttons or LEDs (e.g. for BDCOK status) so I can't easily tell if what I have is good or not... I've not gone too much further yet but thought I'd try and get some knowledgeable input to make sure I'm not going down the wrong path. One thing I have found is the -12V supply that's only used inside the PSU (and feeds the power monitor board) is at ~-15V. Many thanks for any advice! James

The top head mechanism seems exceptionally fragile. I went though a stack of drives where most of the metal flexures have bent up so the head no longer makes contact with the media. Sony doesn't seem to have done a very good job of the mechanical design on this.

RD53 Stiction

by robert.jarratt＠ntlworld.com

I have an RD53 which is suffering from the sticky bumper problem. Normally I can resolve this with a sliver of paper placed over the sticky bumper. But in this instance it seems the bumper has practically liquefied and I think it has gummed up some of the mechanism. Is it feasible to dismantle the assembly to clean it up? Has anyone ever done this? Any advice? Thanks Rob

New in collection: HP-85a

by oe5ewl＠gmail.com

Hi folks, today I got a HP-85a for my collection (got it from a workmate whose father died recently). It's in good physical and optical condition, very little signs of use. With the machine came 2 tape carts, one 16k mem-board, a spare roll of thermal paper, the user manual and a BIG carrying-case for the machine and the parts. After a quick check (psu) I turned the whole thing on and - whoopee, it's behaving like as it was new :D Sorry for the spam, but I wanted to share my happyness.

What is Fast Diagnostic Mode?

by robert.jarratt＠ntlworld.com

I got given a third party (Phillips) 32MB module for my VAX 4000-200 recently. I have just installed it. While it seems to work I get this from the console: >>>sh mem Memory 0: 00000000 to 00FFFFFF, 16MB, 0 bad pages Memory 1: 01000000 to 01FFFFFF, 16MB, 0 bad pages -- FDM (fast diagnostic mode) not working Memory 2: 02000000 to 02FFFFFF, 16MB, 0 bad pages -- FDM (fast diagnostic mode) not working Total of 48MB, 0 bad pages, 120 reserved pages >>> What is FDM exactly? I suppose it is a feature that is not present on this board as it is 3rd party, but I wonder if it can have any impact beyond affecting diagnostics? Thanks Rob

Alphaserver 1000A power supply shutting down

by CCTECH＠beyondthepale.ie

I have an Alphaserver 1000A which began intermittently halting, same as if the halt switch had been pressed. At the time it had a serial console. I thought it might have been picking up noise on the serial line and interpreting it as a break signal so I changed over to a graphics console. It still halted intermittently. This problem either went away or the following problem caused me to not notice it any more. The machine started intermittently powering itself down, requiring it to be switched off and back on again to reset the power supply before it could be run again. The machine might stay running for several hours or it might power down less than a second after switching on, or anything in between. Thinking that the two problems might be related, I investigated the operator control panel on which are mounted the low voltage on/off switch and the halt switch. I found the two switches to have little in common and my theory to be unlikely to be correct. The on/off switch and associated circuitry appear to be working correctly, as does the interlock which cuts power when the lid is removed. I tried a power supply unit from another Alphaserver 1000A and found this did not cure the problem so I replaced the original. Thinking that the power supply might be sensing an overload, I disconnected the power feeds to the disks/cd/floppy and removed all the PCI cards. The problem was still there. When it was failing regularly, I found a line going to the power supply which normally sat at 0V and pulsed high just as the power supply shut down. This line did not pulse the same way when the power was turned off normally. I suspect it is a signal from the system board to the power supply requesting it to shut down, or less likely, a signal from the power supply to the system board signalling it has a problem and is about to shut down. I have a service guide which mentions the possibilty of the power supply shutting down due to a fan failure or high temperature but it doesn't give any details on how this works or even how to find out if it is happening. Does anyone have any detailed information about the power control system in the Alphaserver 1000A or any helpful suggestions? Regards, Peter Coghlan.

Tandy 102 display fault

by jules.richardson99＠gmail.com

I managed to scavenge a Tandy 102 earlier today (1988 build, 32K memory). Physically it's in good condition, and powers up, but the display's a bit unwell, having an entire row of dead pixels 4 up from the bottom, and a 32-pixel high column of dead pixels 22 pixels in from the left (on just the lower half of the screen, the upper 32 in that column are OK). The fault seems a little bit more subtle than that, however; sometimes (depending on which app I'm in, and the angle of the screen, and what I type) I can see some garbage in the first two characters (12 pixels) of the dead row - usually much fainter than normal "on" pixels (barely even visible), and occasionally a fully-on pixel, but at the wrong x-offset for whatever I've typed. Question is, where to point the finger? I've no idea how the 102 addresses the screen, although when I was checking it over inside before powering on I noticed all of the HD44102 ICs - are each of these responsible for a small rectangular area, or is the relationship between them and their pixels more complex? Could a fault with one potentially knock out / corrupt an entire display row? Does anyone have a simple BASIC listing for a main memory check? That could be useful (one particular reason for mentioning that is that when I first powered the machine up, it had a non-default date and showed some files present, but in trying to scroll through the contents of one it reset, lost the files, and set the date back to 1900). I already re-seated the cabling between display and the main logic board; the cable itself looks to be in good condition with no signs of severe distress, but I'll check the individual lines with a meter just to be sure. cheers Jules

But in my experience with dozens of PETs and AIM65s, some working in extrememely hostile environments, I found that a remarkable product called Stabilant-22 almost totally eliminated contact problems (unless there was actual damage), and virtually eliminated frequent socket-related service calls. I don't recall having to replace a single socket; the only issue with certain socket types is that with a lot of vibration or circuit board flexing the chips sometimes migrate out of their socket. It's expensive but it does work and a little goes a long way.

[TRS-80] Reviews of TRS-80 and compatible computers in magazines of the 1970s & 80s (fwd)

by geneb＠deltasoft.com

[This showed up on the TRS-80 list that I'm on. I figured many of you here would enjoy it. -g.] ---------- Forwarded message ---------- Date: Sat, 16 Jul 2011 09:01:17 -0000 From: Rainer <fredrich at .......de> Reply-To: TRS-80 at yahoogroups.com To: TRS-80 at yahoogroups.com Subject: [TRS-80] Reviews of TRS-80 and compatible computers in magazines of the 1970s & 80s For some TRS-80 fans it may be interesting to have a view on the editor's judgements from the earlier times when these computers were displayed in computer shop's display windows for sale. The technical details of the reviewed computers are more precise and meaningful than the shorthand technical specifications found on modern computer museum internet sites. Some of the reviews are more well disposed and other less. Because of the different views of the various editors the reader can make himself a pretty good overview about the desired computer model. Since some of the reviews are difficult to obtain nowadays I think it might be useful to make them available in this manner. Beside the elder TRS-80 computer enthusiasts (I'm 51 years old) which are familiar with most of the TRS-80 models since the late 1970s there may be younger ones who could be supported in their decision to obtain a specific model. The containing information of the reviews might bring some light in the beginner's lack of knowlegde of the different types of TRS-80 and compatible computers. BTW, are there any younger TRS-80 users among us (born after ~1980) or do the group members consist only of survivers of the former 8-bit times? The reviews are taken almost all from independent magazines like Byte or 80micro and similar printed publications. The pages from the magazine 'Microcomputer News' should more seen like an introduction and advertisment than real reviews because this magazine was published by Radio Shack. Nevertheless I have added for completeness a few of the overviews from this magazine too. Some of the models have more reviews than others. That's because my access is limited to only a small fraction of all ever printed issues of the various computer magazines. For example: the Model III which is represented only by one review is accidently the least recognized computer in this collection despite the fact that this model is one of the most spread ones. Does someone have another review of the Model III? I've collected all the reviews found in magazines that I have (had) personally on paper or that are (were) accessible in digitized formats (PDF, JPG or plain text) on the internet. Regardless of the original data format all the reviews are now in PDF. Featured Tandy Radio Shack computers: - TRS-80 Model I - TRS-80 Model II - TRS-80 Model III - TRS-80 Model 4 - TRS-80 Model 4P - TRS-80 Model 12 - TRS-80 Model 16 - TRS-80 Model 16B - TRS-80 DT-1 - TRS-80 Color Computer Featured TRS-80 compatible computers: - PMC-80 - Dick Smith System 80 - Video Genie - Lobo Max-80 - LNW80 - Trommelschlaeger TCS GENIE IIIS - Trommelschlaeger Speedmaster The examined magazines (nearly all in English language exept the mentioned German magazines): - 80micro - Byte - 80-US - Microcomputer News - Creative Computing - Infoworld - Micro-80 - CHIP (German language) - c't (German language) - Computer Persoenlich (German language) The reviews of the specific models are integrated to sets of PDF files and packed in RAR archive files. To unpack the desired file you can use the program Winrar for example. Other packing programs like Winzip may work as well. For more information look at: http://en.wikipedia.org/wiki/RAR_(file_format) The sets are named: TRS-80_Model_I_Reviews_(Version_YYYY-MM-DD).rar TRS-80_Model_II-12_Reviews_(Version_YYYY-MM-DD).rar TRS-80_Model_III_Reviews_(Version_YYYY-MM-DD).rar TRS-80_Model_4_Reviews_(Version_YYYY-MM-DD).rar TRS-80_Model_16_and_Terminal_DT-1_(Version_YYYY-MM-DD).rar TRS-80_Compatibles_Reviews_(Version_YYYY-MM-DD).rar Color_Computer_Reviews_(Version_YYYY-MM-DD).rar Additionally for the interested party that like to have all reviews a RAR file is available that includes the whole collection: Tandy_Radio_Shack_and_Compatible_Computers_Reviews_(whole_collection)_(Version_YYYY-MM-DD).rar A set's version date (Version_YYYY-MM-DD) is updated every time a new review is added to the set. The first version date of all sets is 2011-07-12. Coming updates will be published here. Each archive file is stored on two different file hosting services for downloading. You can choose your preferred file hoster. The files are usually deleted by the services after a period of 30-60 days without a download. Please let me know if a file isn't accessible anymore.

PDP-11 on an S-100 Card

PDP-11 on an S-100 Card Steven M Jones classiccmp at crash.com Thu Jul 14 19:00:45 CDT 2011 Previous message: Seeking Morrow MPZ80 rev3a PALs Next message: PDP-11 on an S-100 Card Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] There was a thread here or on the N8VEM-S100 list about putting different vintage CPUs on a newly designed S-100 boards. I happen to be cleaning up my office and came across something done back in the day worth noting on that theme... In the May 1984 issue of Microsystems, /The Journal for Advanced Microcomputing/ (Vol 5, Num 5), there is a directory of S-100 products. ABACUS Technology Systems, Inc is among the vendors listed, and on page 67 they have a 1/4 page ad for their PC11 product - right next to a similar ad for the Lattice C compiler. This board features a T11 with 32KW of RAM, and runs RT-11 v5.0 with compatible I/O devices emulated somehow by a CP/M program (presumably running on an 808x/Z80 card in the same chassis). Here's the full text of the ad: [snip] -----REPLY----- Hi! It was on CCTALK mailing list the S-100 PDP-11 was discussed a few weeks ago by the people here. My offer to build a board still stands but it will take some effort of someone(s) who can design the schematic and write the software for whatever free/open source software is necessary. As I recall, the project fizzled since the obstacles to overcome were simply too enormous. That's a shame however if someone gets ambitious and wants to take this on please let me know since I'll volunteer to make the PCB, get some prototypes, etc. Thanks and have a nice day! Andrew Lynch

Terminal server advice

by bdwheele＠indiana.edu

Hey all! I'm planning to upgrade my home network at some point in the not-too-distant future and I'm trying to figure out what to do with my serial-terminal-console machines. Right now I'm using a decserver 200/mc to connect to them, but its always been a little fragile: It doesn't seem that most switches understand MOP (so it won't boot) and requiring a lat client leaves a lot to be desired. The connected serial terminal works great but parts of me are wanting to move to something that takes up less space and is more tcp/ip friendly. What is everyone else doing for this? Just a back of the envelope count looks like there are around 8 serial-consoled machines. I've thought about using usb-to-serial adapters but that seemed kind of hacky. The machines are a mix of OSes, and some of them are Suns, so the break/disconnect signal is always...amusing. If I can ditch the mop requirement I should be able to get rid of my aging (and noisy) hub and move everything to switches (since I don't use decnet either) Anyone have any suggestions? If I can get a reasonable solution I'll probably get rid of the pair of ds200's I have (one with skins and the other without). Brian

Disc for "The SCSI Bus and IDE Interface" (Schmidt)

Hi guys, Does anyone have a copy of the floppy disc (or possibly CD) which accompanies the Second Edition of "The SCSI Bus and IDE Interface" by Friedhelm Schmidt? I just bought an ex-library copy of this, and the disc is naturally missing. The local library is showing their copy as "Sold/disposed, content no longer relevant"...

Identifying the Surge Suppression Resistor in PDP11 H7140 PSU

by robert.jarratt＠ntlworld.com

Work is continuing on repairing the H7140 PSU from my PDP11/24. Now it seems that the surge suppression resistor across the relay has failed. This resistor is marked as R1 on the printset (p66 and p69) but actually is two components connected in series. The parts list on p71 of the printset lists a 3ohm 7W 5% resistor, but it is not 100% clear if this is supposed to be the surge suppression resistor, although it does seem likely. The thing is I measured the resistance of the two resistors (in-circuit), one was open circuit and clearly the failed component, the other measured 10ohms, it might be failing too I suppose. The two resistors are marked KCC 13-17198-00 8234. I have not been able to find any information on them, so I can't verify the spec and I don't know what to replace them with. Does anyone have any information on these resistors? Thanks Rob

Seeking Morrow MPZ80 rev3a PALs

by dgriffi＠cs.csubak.edu

I sold a Morrow MPZ80 rev3a S100 CPU board to someone recently (who is probably on this list). Somehow I didn't notice that the board was missing chip 15A. I don't have any more MPZ80 rev3a board with that part still mounted. What I want to do is find someone who has this board in a working state to dump that PAL for me. I don't have the ability to dump and burn PALs, but I'm working with some people who do to get this oversight fixed. If you can't dump PALs, please contact me anyhow so we can get something set up. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

PDP-8 documents needed

by djg＠pdp8online.com

I recently acquired a PDP-8/L system with BM08 memory expansion and Computer Operations CO-600 LINC tape drive. Does anybody have documentation on the BM08 (preferably the 8K additional core model) or the LINC tape drive? I looked in the normal spots and didn't find any. The closest was the MC8/L 4K memory option on bitsavers. If interested pictures are here until I create a real page: http://www.pdp8online.com/ftp/misc/pdp8l/

At least one of the DSes and one of the XMs runs. I drove a DS once, on a gravel road full of potholes in the south-west of France. Absolutely amazing, it just floated along, one hardly felt the potholes... OTOH on another holiday in France we were overtaken by one with a whole family in it. A little while later there had been an accident, the DS that had passed us had collided with a lorry. It had been literally flattened, it looked like it had been squashed with a rolling-pin. Very tragic :-( It would have been nice if they were still made, but with more crash-proof bodywork. /Jonas

The cases were fragile and yellowed and the keyboards often could not cope with student use. There were a lot of minor video faults, typically vertical linearity. Older and grottier ADM5 terminals seemed to be built like tanks in comparison. The thing that irritated me the most was the loud and grating beep. They seemed slow for a given bitrate compared to other terminals, even after turning off the smooth scroll (which was quite cool if you ever had time to wait for it which noone ever did). The VT100 protocol was a great step forward but it seemed slightly over-complicated and bloated. A pity that many writers of terminal emulators and terminal driver software failed to grasp the point of it and came up with broken implementations. I was much happier with the VT220 which seemed to solve a lot of the version 1.0 issues of the VT100. However, it didn't really look like a terminal. Maybe a VT220 in a Commodore PET case would better fit the bill :-) I have an ADM5 and a VT220 but I would not be interested in having a VT100. Regards, Peter Coghlan.

Hi guys, Does anyone have a copy of the floppy disc (or possibly CD) which accompanies the Second Edition of "The SCSI Bus and IDE Interface" by Friedhelm Schmidt? I just bought an ex-library copy of this, and the disc is naturally missing. The local library is showing their copy as "Sold/disposed, content no longer relevant"...

Anyone interested in IBM PC/RT gear? (located in PA USA)

by bli＠psu.edu

I wasn't sure if there might be any parties on the list who would be interested in old (late 80s/early 90s) vintage IBM PC/RT gear. Also of potential interest to collectors of the later PowerPC gear as this was the predecessor. I have several items that may be of interest to hobbyist/collectors and I really do not have the space for them but also have no desire to see things end up in the dump if they can find a good home. Any interest at all? I do not have a current inventory but I know I have ... a couple PC/RT 6150 server towers (worked after Y2K, haven't run them much since) a couple PC/RT 6152 minitowers (based on a PS/2 Mod 60 w/ add-on RISC cpu card, think I have one or two that work & another "shell" for parts) a pair of streaming tape drives (one working, one I don't remember trying recently) various monitors, keyboards, mice, tablets, & cards and so forth (some working, some may need repair) documentation/software binders for AIX and AOS (BSD) ... if anyone is interested, I can get you an inventory in a few days' time with more details. I would be looking for someone to take the whole lot I think, rather than unload some things & still be faced with the prospect of sending these off to the dump for lack of space anyway. And ideally someone who would try to get the old parts back into a functional state or as a "museum piece" or something like that rather than melting it down for gold. Not looking for any money, my monetary investment was paid off by several good years of use over a decade ago. Definitely a "come and get it" as these are old, heavy and I doubt that they'd be worth while to ship. If you are at all interested, let me know -- Thanks! -j Jeff Brendle Office: 243 Deike/(814)865-3257/fax 865-3191 Desktop Support Spv.

HP disk power unit

by wdonzelli＠gmail.com

Today I scored an obscene collection of TTL and ECL chips, in a weird sight unseen sale (the guy was selling the parts drawers as drawers, and would NOT let buyers see what parts were inside!), but that is not the point of this post. Well, maybe I am yanking the chains of all those people that say TTL and ECL is getting hard to find. ANYWAY... Also scored was a power unit to an HP 7900A disk - the 14 inch unit >from the 2100A and friends. Very nice condition, and heavy as sin. I do not need it, but it was sitting there so forgotten and lonely. Does anyone need one of these supplies? Very nice condition. I forget the HP number - 13mumblefooA. I really do not want to ship it, but could deliver it to MIT or any of the other area hamfests. -- Will, in 10512

Unibus Framebuffer information needed (DDS)

by ball.of.john＠gmail.com

By luck I stumbled across what may or may not be a complete hex-width Unibus framebuffer board set made by Dynamic Digital Displays. Now that would be cool in the PDP-11/84. :) I can identify three of the boards but not all of them: -FB1000FBL001 Serial 55 Rev. 2 (looks to be the main memory as well as the D/A logic to output to RGB) -1000VB-001 Serial 35 (calls itself the "Voxel Buffer") -1000CTD001 Serial 47 (calls itself the "CTU Board") These boards can be seen at the following link: http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/100_206… Then there were two other boards that the seller had as well. They may be related to the previous three and they also might not be. -1000HIL001 Serial 45 (board calls itself "HI") - http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/100_206… -1000DTD001 Serial 54 (calls itself "DOTS") - http://i11.photobucket.com/albums/a166/ballsandy/Computer%20related/100_206… Unlike the first three boards, these ones have "Dynamic Digital Displays" on them, however the model numbers are similar on their structure. The unfortunate part is that these boards have connectors on them ("HI" board has three 40-pin ribbon cable headers, "DOTS" has two 50-pin ribbon cable headers) so either I'm missing more boards that that talked through their own bus and not the Unibus, these connectors are for options, or there is additional hardware/cards I am missing. I have no way to read the two TMS27C512 EPROM chips and Google has pretty much nothing about these boards that I can locate and their hand written serial numbers mean these are something special. Might anyone have further information on this?

Microprocessor simulators

by CCTECH＠beyondthepale.ie

A while back, there was a brief discussion on the list about microprocessor simulators running on larger systems. Some interest was expressed in the simulators I was involved with some years ago. I've put together some details and some code here: Z80 simulator in FORTRAN IV for the MUSIC/SP IBM mainframe operating system http://software.beyondthepale.ie/music/z80/ 6502 / BBC Microcomputer simulator in FORTRAN and 370 assembly for MUSIC/SP http://software.beyondthepale.ie/music/y6502/ 6502 / BBC Microcomputer simulator in FORTRAN and VAX assembly for VAX/VMS http://software.beyondthepale.ie/vms/y6502/ All the bits and pieces are provided to run the first two simulators on the freely available "MUSIC/SP Demo system" running on Sim390 or Hercules and the latter one on any reasonable VAX/VMS platform or simulator. The original unmodified code is also there. With the addition of a BBC Micro BASIC ROM, it is possible to run text based BASIC programs such as http://software.beyondthepale.ie/bbcmicro/survival/ (an adventure game) on the latter two simulators.

Cromemco D+7A troubleshooting question

by rich.cini＠verizon.net

All -- I?m finally getting around to building the JS-1 joystick replica and using a D+7A board I got a few months ago. I have the JS built but now I?m trying to recalibrate the board per the instructions on page 4 and I?m having trouble getting it to read the right values. The calibration procedure, basically, starts with putting 2.54v on an analog input and using a short program to read the input and display it on the front panel output port of my IMSAM. There are two problems. When reading the A/D and displaying the input, bit7 is stuck ON. The second problem is that I can?t get the input to read the maximum positive of 7Fh (excluding the seemingly stuck bit7). The version of the schematic I downloaded isn?t a very good scan, and doesn?t seem to be the same revision as my board (because the adjustment pots have different reference numbers). There are a few common chips that touch bit7 (like the LS367) which I can swap, but the others, like the AM2502 successive approximation converter, isn?t as common. So before I go swapping chips, does this board have any common failure mode I should be looking for? Thanks!

PCB is a great stand alone PCB layout tool that includes an autorouter. Agreed. However, if you are going to use the PCB autorouter you must use PCB for your PCB layout. For example, how does one get their PCB layout into PCB to use its autorouter if you uses KiCAD, FreePCB, or Eagle? There is no interchange standard AFAIK. I think we've lost focus on the original topic of this thread so I will repeat it. If you are a software developer with familiarity with EDA and are able to help develop a truly free/open source PCB autorouter this is a great opportunity to help the hobbyist EDA community. This is desperately needed IMO. Hobbyist PCB autorouters are either non-free or lack support of interchange standards. QAutorouter has promise to open up free/open source PCB autorouting to all the hobbyist EDA toolsets that support Specctra DSN export and SES import such as KiCAD, gEDA, FreePCB, and Eagle. Please consider. Thanks and have a nice day! Andrew Lynch -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi All, I'm working on a project here http://sourceforge.net/projects/qautorouter/ It is an auto-router that is written in C++ on Qt application framework, reads/writes specctra file format and uses a plug-in style of interface for the router engines. It is very alpha at this stage, I have much of the UI, file I/O, and the plug-in API operational. I am working on a "Simple Router" plug-in at the moment that is implementing a simplified version of the expanding box algorithm. The Simple Router will be used as a sort of template for debugging the plugin-api and as a template for developing more sophisticated plug-ins. Toporouter would be a good one.

PCB, http://pcb.gpleda.org/news.html And it's available on sourceforge, http://sourceforge.net/projects/pcb/ And you can track the progress here, https://launchpad.net/pcb/ Why reinvent the wheel ?? They could probably use more coders to support this. =Dan -----REPLY----- Hi Dan, You've missed the point entirely. Yes, gEDA includes a PCB layout tool (PCB) which includes an autorouter. However, they are closely coupled and if you want to use the PCB autorouter you must start with gEDA EDA tool set and stay with it. There is no import/export capability so if you use KiCAD, FreePCB, EAGLE, etc then you are out of luck. This is the "lock in" which plagues the whole EDA technology because there are few if any interchange standards. There is no way to import/export PCBs in/out of gEDA AFAIK, at least from KiCAD. I can't tell if gEDA supports Specctra import/export necessary to use FreeRouting.net but doesn't appear so. QAutorouter is a *much* better approach of decoupling the autorouter from PCB layout tool. Any EDA tool set that can export Specctra DSN and import Specctra SES files can use QAutorouter. Also since it has an API which allows multiple different free/open source autorouters to "plug in" the hobbyists can potentially use MUCS-PCB, Topological Autorouter, the gEDA PCB autorouter, the KiCAD autorouter (yuck), or new autorouters. Really the PCB layout tool and the PCB autorouter are so different they *should* be separate tools. Integration just leads to yet more EDA "lock in". Personally, I won't even consider gEDA since I have 50+ complete boards in KiCAD format. KiCAD is not perfect by any stretch but it supports at least some level of EDA interchange standards (Specctra at least). http://en.wikipedia.org/wiki/Comparison_of_EDA_software Thanks Andrew Lynch

Surely if it had holes you wouldn't need to worry about opening it? Or are there times when you need the valve closed? Regards, Andrew B aliensrcooluk at yahoo.co.uk

I assume it's digital because it makes it quicker to get images from it, and if it was film-based the film would have to be huge, right? Regards, Andrew B aliensrcooluk at yahoo.co.uk

DEC RD53 Manual

by jonas＠otter.se

Will a flatbed photo (transparency) scanner not do? My Epson 4180 will do 4800 x 9600 dpi and I should think a fiche would fit under the light in the lid without an adapter, or one could make up some sort of fiche adapter from polystyrene sheet from the model shop. If an entire fiche does not fit at once, one could scan it in two passes. /Jonas

Titan IV Missile Test Equipment

by nick.allen＠comcast.net

Hi everyone, could use some help identifying some equipment if you are up to it. I know it is some sort of test equipment for the Titan IV Missile, just not sure what it was used for, and cannot find any literature (maybe you can help). Below is a link to the photos of the Titan IV Missile Test equipment, notice it comes with paper tape ribbon (I assume some code is on it). Also notice the "Air Pressure Equalizer" knob, this lets air in/our of the case (it is sealed with a gasket). Do you know why it would have an "Air Pressure Equalizer" knob? I assume this means it is used in different air pressures, would this therefore be used in space as opposed to on the ground in your opinion?

Usefullness of a CX-11 controller

by quapla＠xs4all.nl

Ok, I have this CX-11 which is a half rack full of backplanes & flip-chips and has also a half sized lights top panel. It's a Unibus controller to talk to an IBM bus and tag device. There are 2 large 'In' connectors and also 2 'Out' connectors. I do have a manual which describes some generic IBM info, but I would like to know what kind of device(s) could (if possible) directly be connected to such a thing? Thanks, Ed -- Dit is een HTML vrije email / This is an HTML free email.

Seeking surplus IBM bus / tag cables and terminators?

by ceby2＠csc.com

I'll second that plea. I have a full 9221 mainframe (2 IO cages and 5 DASD) but NO cables. Sigh. Haven't found any here in England so far. So if there are stacks of them eating up space under your raised floor, or in your garage, please consider me too! Thanks, Colin Eby
