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/

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.

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.

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. In any case, it would be great to get a few other people on-board, a developer or two that is quite proficient in C++ would be very helpful, some hands-on with Qt would help a lot too. Someone to look after the Windows(tm) and Mac OS-X build and release would be very helpful. Someone to help with packaging; windows installer, Mac OSX installer, and linux .deb, .rpm packages would be helpful as well.

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

Looking for a Franklin high speed digital printer

by wlsilva＠sbcglobal.net

Hello. Looking for a Franklin high speed digital printer, these were made in the 1960's and early 1970's. The printer is a rack mount unit, and prints on adding machine width paper. If you know of one, or even any information or manuals I would be extremely grateful for the help! I have more information on the unit if anyone can help. Best regards :) Walter

free/open source PCB autorouter software development

by lynchaj＠yahoo.com

Copied from KiCAD-users mailing list. Hobbyists have long needed a free/open source PCB autorouter for their EDA tool suites. One is now in development. Please support this project. This is not my project but one I strongly believe is very good for EDA hobbyists. Certainly useful for KiCAD and maybe gEDA as well. -----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. In any case, it would be great to get a few other people on-board, a developer or two that is quite proficient in C++ would be very helpful, some hands-on with Qt would help a lot too. Someone to look after the Windows(tm) and Mac OS-X build and release would be very helpful. Someone to help with packaging; windows installer, Mac OSX installer, and linux .deb, .rpm packages would be helpful as well. If you're interested, please just send me a little about what you can contribute, and your sourceforge id.

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

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
