DRAM memory for NorthStar Horizon

by ian＠platinum.net

Hello All, Does anyone have an old National Semiconductor memory data book lying around? I have found the problem with my second 32k memory board - 3 bad DRAM chips. This board is populated with MM5298N-3B chips. I can't find an online data sheet that talks about the speed grade (I'm assuming that's what the 3 is referring to). The manual for the board ( http://www.hartetechnologies.com/manuals/Northstar/NorthStar%2032k%20RAM-32… ) says that the RAM is 200ns access time. I can find a source for MM5298N-4B chips, but I don't know if the 4B is still fast enough. I'll replace the entire bank of 9 chips at the same time so that they are matched. Thanks for any assistance. Ian

DRAM memory for NorthStar Horizon

by james＠attfield.co.uk

Ian, I'm afraid my NatSemi data book only goes up to MM5290 (16Kx1 Dynamic) but the '-3' variant is 200nS as is the MM5298-3 and it lists the '-4' variant as 300nS. Unless I had no option I wouldn't use the slower chips whereas the 150nS would do fine although without any real feel for the tolerances of the chips, board design wait circuitry (if exists) or the refresh controllers it is not really possible to say with any degree of certainty.

Parallel Port/Firewire/USB to IDE Bridge Specs

by t.gardner＠computer.org

Anyone have any specs on any of the several chips or controllers that were used to bridge IDE HDDs to another interface such as PP, FW or USB. I'm thinking of products of Shuttle Technology, Indigita, ASP, etc. Alternatively, can anyone point me to an open source driver code for such bridges, perhaps Linux? Tom

Digital DECpos2 Documentation?

by nf6x＠nf6x.net

This will be a long shot... Do any of y'all happen to have PDF documentation for a Digital Equipment Corp. DECpos2 computer, model MT100-AA? This was a small Pentium PC made for point of sale applications. I found documentation online for an older 386SX based DECpos system, but nothing for the newer DECpos2 yet. Yes, this is related to Other Stuff I've been asking about here recently. ;) In particular, I want to find out whether its onboard floppy controller can be disabled. The 386SX-based version does appear to have that option in its BIOS settings, according to the user/installation manual I found. -- Mark J. Blair, NF6X <nf6x at nf6x.net> http://www.nf6x.net/

Help building a DOS system for ImageDisk

by billdeg＠buzz1.com

> I'm trying to put together a DOS system on which to run the ImageDisk software, as found here: > http://www.classiccmp.org/dunfield/img/index.htm Here is a thread on my site about my Pentium III system dedicated to imaging disks, plus a link to the class notes from the talk at the VCF East last spring: http://vintagecomputer.net/browse_thread.cfm?id=561 I am using a generic Pentium III, which will handle the Adaptec card you have in place of the Catweasel I have.The drive controller of the Pentium III has no issues with a 5 1/4" HD drive, which with an adapter can mimic a 77 track 8" drive. Note that I have a dual boot system, Dos 6 and Windows 2000. Works perfectly. Very little I can't image with this that is image-able. I also intend to put in a Quad Density drive, but I have not gotten around to it yet. The quad density I believe will look to the Pentium Bios as a 720 3.5" drive. In short, make your life easy, use a Pentium III with a compatible BIOS. Bill

Packages for Mac OS X on PowerPC hardware

by venture37＠gmail.com

Hi guys, I'm a long time lurker but this is my first to the list, If anyone still running OS X on PowerPC Macintoshes is interested, I've started building packages on Tiger 10.4.11 using pkgsrc & publishing them for others to use. I've written up a brief post on how to get started at http://www.geeklan.co.uk/?p=1579 if you've not used pkgsrc before. Packages are currently published at http://sevan.mit.edu/packages Let me know if you experience any issues, the aim of this exercise is to get familiar with building software & through that improve support for Darwin in pkgsrc. The number of published packages is growing (slowly), if there's something you specifically need, it'll show up eventually as the pkgsrc tree is built but feel free to email me off list if you'd like to add something to build list beforehand.

Help building a DOS system for ImageDisk

by hp-fix＠xs4all.nl

HP Vectra VL2. Very sturdy machine, with 4 ISA slots and 486 overdrive compatible. Mine works perfect for more than 15 years, I use it for the hp language processor board and elv ic-tester. -Rik -----Oorspronkelijk bericht----- Van: "Mark J. Blair" <nf6x at nf6x.net> Verzonden: ?2-?8-?2014 23:27 Aan: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Onderwerp: Help building a DOS system for ImageDisk I'm trying to put together a DOS system on which to run the ImageDisk software, as found here: http://www.classiccmp.org/dunfield/img/index.htm The ImageDisk documentation recommends at least a 486-class system for best results, although it'll run on an original PC: "ImageDisk requires a DOS based PC with an AT type floppy controller. Although ImageDisk will run on a 4.77Mhz PC/XT type machine, some of the analysis functions are real-time intensive and best results will be obtained with a 486 class machine or better." ImageDisk is naturally finicky about its floppy controller, since it uses modes that are not normally employed for MS-DOS disk formats. After studying the list of controllers known to work well with ImageDisk, I ended up buying an Adaptec AHA-1522A SCSI controller on eBay, because it's built-in floppy disk controller happens to be a good one for this application. It's a 16-bit ISA card. I thought I already had a computer to plug it in to on my junk pile, but those all turned out to be much too new, with PCI slots only. Thus, I'm looking for some help looking for a machine that I can buy for running ImageDisk on. I don't want to waste space with any old arbitrary no-name clone machine; I'd like to get something that has some collector appeal all by itself, besides its utility for running ImageDisk with that AHA-1522A. The only PCs I'm familiar with that particularly interest me on their merits would be the original IBM PC and PC-XT. Those seem like they would be under-powered for this application according to the ImageDisk documentation, though. I hope that somebody who's more familiar with vintage PCs than I am can help me find a machine that meets these goals: * Must have at least one 16-bit ISA slot to accept the AHA-1522A board. * Must be able to disable any on-board floppy controller so that the AHA-1522A's floppy controller will not conflict with it. * Should be "486 class" according to the ImageDisk notes... yeah, I know that's a bit of a nebulous requirement. * It would be nice if it has an IDE controller so I can use an IDE to CF adapter in place of any hard drive. * It would be nice if I can use an SVGA LCD monitor that I already have with it. * It would be nice if I can use the Model M keyboard with PS/2 interface that I already have. * I really, really, hate orange Compaq displays. :) * Preferably not too huge. * Preferably not too expensive, and something I'll be able to find in short order on eBay or from another collector on this list. * I'd just run DOS on it, and I wouldn't care at all about things like mice, sound, etc. * Not a no-name clone; something that has some unique collector appeal of its own. This will be hard to satisfy, as I consider the "486 era" to have been an especially boring era of computing. :) * It'll be helpful if the case is easy to open, since I'd regularly need to plug in various disk drives, even including 8" ones. Do any of y'all have suggestions? -- Mark J. Blair, NF6X <nf6x at nf6x.net> http://www.nf6x.net/

list archives (/ Thunderbird question)

by jules.richardson99＠gmail.com

Are list messages being actively archived and put online anywhere these days? I have a shade over 68,000 messages in my classiccmp folder, going back to 2008, and Thunderbird is about ready to explode. I need to have a clear-out; can I delete them because they're available somewhere, or am I better off keeping a snapshot of what I have? I'm sure other people have offline copies too, but I'm more interested in them being immediately accessible should I want to refer back to something I know I've seen in the past. If I remember right, the archives on classiccmp.org itself have always been a bit patchy. (Thunderbird question: If it is sane for me to keep them, do I just need the 'classiccmp' file at ~300MB, or do I also need the 'classiccmp.msf' file at ~36MB? I'm not sure if the latter's perhaps just an index which will get regenerated in its absence anyway?) thanks Jules

IBM 3278 term needs keyboard

by silent700＠gmail.com

My insatiable terminal collecting habit has cost me another couple square feet of space. By way of a well-spotted Craigslist ad, I have acquired an IBM 3278-5 terminal: https://picasaweb.google.com/102190732096693814506/IBM3278Terminal I'll need a terminal controller, so it'll be a long time before this term sees a mainframe session again. But it does power up and I'd like to at least test the local mode, so I'll need a keyboard, too. A few have appeared on eBay recently and sold for much more than I expected. Apparently there are a lot of 'boardless terminals out there. Aside from waiting patiently for one to come along cheap, what are my options here? The keyboard connector is a 25 pin and I believe it uses a serial protocol. Are there other IBM keyboards that may work? Any that can be adapted? For terminals, I have a 3178 keyboard (p/n 6052141) with the 15-pin connector. I know there is a 3278 -> PS/2 adapter project out there but it was intended to go the other direction, to use the 3278 keyboard on a PC. Perhaps it can be adapted to go my way? -j

HP 85 Flyback Transformer

by pdaguytom＠gmail.com

I've got an HP 85a that didn't fare well in it's recent travels to me. The flyback transformer broke away from the video board breaking 4 of the 6/7 leads (this was apparently an early flyback, it had a U shaped threaded rod secured with nuts & washers on the backside of the video board that broke at the outside bend). The unit did boot and run before it's trip so its worth repairing. I've not been able to source the transformer (or the video board) at anything below just buying a complete machine again. Anyone got a lead on one or know of a transformer that could be substituted? Tom

11/785 update- Ramtek Marquis

by useddec＠gmail.com

I looked at the 785 today, and the expansion cabinet there, but no disk or tape drives were found. As I stated earlier the cpu boards are gone, but there are boards in the BA11-KE. I have a set of 780 boards, but not sure if I have all of the 785 boards. Now the kicker- last time I saw the drives, which I didn't see this time, But I found a Ramtek Marquis model III. I believe it is a graphics processor. It might be able to be sold separately, and is in what seems to be in a H9642 cab. I do not own this, and can make offers. He has a fork lift and can load. I'm not sure if William is willing to transport them and would suggest you contact him directly and he is already planning. If you have any questions feel free to contact me. Located in IL.

Oiled paper tape is because.... ?

by tshoppa＠wmata.com

Been having fun, restoring and using an old hand-cranked Instructograph - apparently I have the original ten tapes, plus an extra 11th one too. Just like many 5-level and 8-level paper tapes I've dealt with, the Instructograph tapes ("1-level"? 2 levels if you count the flip-over direction) are oiled. Is the oiling of paper tape, done only to oil the punching machine originally, as the www.westnc.com<http://www.westnc.com> paper tape page implies? Or does it also help prevent brittleness and feed around the small diameter rod in playback path too? Tim N3QE

TU56 and G888 Module

by marco＠familie-rauhut.eu

Hello list! i`am working on the restoration of my TU56 Drive. It has an overvoltage damage. The manual transportlogic control and the transportcontrol by the TD8E is working correct. Now i`am in trouble with the G888 Manchester read/write Modules. Specialy with the adjustment of the zero crossing detector. In the maintanence manual i could not find any information on the correct adjustment and originaly the poti is secured by black paint... Oszi <http://www.familie-rauhut.eu/pic/oszi.gif> The yellow graph is the output of the first Amplifier witch is amplified the read heads outputsignal. The blue signal is the output of the nand driver(7400) after the zero crossing detector. In case of the term zero crossing detector, i placed the rising edge of the output on where the sine wave cross the zero line. Any usefull hints on the adjustment of the "zero crossing" detector?

HP9830B and HP9866B restoration.

by mattislind＠gmail.com

I'd just like to mention that I have completed the repair of a vintage 1976 HP9830B BASIC calculator and HP9866B printer. If you are interested in the story, take a look here: http://www.datormuseum.se/computers/hewlett-packard/hp9830 I also made a short video on it when it is running: https://www.youtube.com/watch?v=WE8KJ4-UcFk /Mattis

My new arrival - MTU-130

by nospam212-cctalk＠yahoo.com

I just received a new system, one I've been interested in for a long time but seen very little about. A 6502 based Micro Technology Unlimited MTU-130. Received the system, monitor, dual 8" floppy drives, a printer and piles of documentation and software all from the original owner who used it for biochemistry research. Particularly can't wait to try out the light pen which came standard with the system. Does anyone else on the list have one? Any other doc or software available? I will have to catalog everything but will scan anything that isn't already out there. The owner is still sending me some newletters and such he found after he sent the system as well as some more background on how he used the system and what he did with it. An old ad for the system for those who aren't familiar with it: http://www.trailingedge.com/related.html?key=mtuad.jpg <http://www.trailingedge.com/related.html?key=mtuad.jpg&type=ad> &type=ad Pics of the new system: http://www.trailingedge.com/images/MTU-130-1.jpg http://www.trailingedge.com/images/MTU-130-2.jpg http://www.trailingedge.com/images/MTU-130-3.jpg http://www.trailingedge.com/images/MTU-130-4.jpg http://www.trailingedge.com/images/MTU-130-5.jpg http://www.trailingedge.com/images/MTU-130-6.jpg David Williams www.trailingedge.com

microcode store (was Re: Looking to get into a MiniComputer...)

by mark.kahrs＠gmail.com

Let me add that the PDP 11/44 was microcoded... Specifically, it was used by CMU to do C.mmp and Cm*. The microassembler was the Most Unlikely excuse for a MicroassemBLEr (MUMBLE), written by none other than some guy named James Gosling. Somehow I ended up with a listing of MUMBLE and the microcode --- I sent that to the CHM. Mark.

The MC68060 shed a number of integer mul/div, FP transendentals, and some variants of conditional MOVE instructions that the MC68040 implemented, as well as some privileged mode instructions like PTEST. I'm sure there are others I've forgotten. Motorola provided exception handling software that would emulate (many) of the unimplemented instructions. MicroVAX dropped BCD instructions. So, I think, did x86_64. KJ

Easy way to get your serial based machines on TCP/IP, Amiga and Apple IIGS

by slandon110＠gmail.com

So ive been dabbling alot with linux, And ive devised a way to get your older machines online via serial. To start you need a null modem cable or adapter A TCP/IP Stack on whatever machine you decide to run on that supports PPP. I run MiamiDX on the Amiga 2000, and Marinetti on the Apple IIGS. Client Setup is like this IP address: Gateway: the IP address of your linux box DNS: use the DNS servers of your ISP or use google public DNS Basically all you need to do is install pppd in your favorite linux distribution. Then create a shell script that looks like this, Replace ttyUSB0 with whatever serial port you are using. Replace 192.168.1.105 with the IP address of your system, then replace 192.168.1.106 with the IP address you plan to give your client system. #!/bin/bash sudo pppd debug -detach proxyarp persist 192.168.1.105:192.168.1.106 ttyUSB0 19200 Then fire up your client machine and you should be able to get right online :) Im going to do this on a RaspberryPi next so I can have a nice small box to do what I need.

ADM-1 wiki entry updated

I seem to recall someone asking about ADM-1s here recently. The reference manual just showed up on bitsavers so I was able to update the page a bit. <http://terminals.classiccmp.org/wiki/index.php/Lear_Siegler_ADM-1> -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://ComputerGraphicsMuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!

NorthStar Horizon Bootstrap Assistance

by ian＠platinum.net

Hello All, I've mentioned before that I'm bringing a NorthStar Horizon back to life. I've managed to get quite far, with a fully functional 32K machine running (the second 32k board has an unknown problem at the moment). I've used Dave's NSI utilities to create a CP/M boot disk, which is now working. CP/M is able to format disks, etc. The problem I'm having now is getting other CP/M utilities in to the machine. I'm thinking that KERMIT is a good tool to get in, because once I've got that, I can use serial to transfer anything else I want. I'm trying to follow the kermit-80 documentation about getting a couple of HEX files in to the machine then using MLOAD to merge them and create the binary. The problem I'm having is that the main kermit hex file (CPSKER.HEX) is 70k in size. I've tried both the bootstrap ASM that comes with kermit, as well as using pip, but as soon as I hit the buffer size and a disk write happens, I get a buffer overflow and the transfer breaks. Does anyone have any ideas? I'm thinking that if I could get the kermit binary (or even the hex files) on to a CP/M formatted NSI image, I could bootstrap that image over. Does anyone have a binary for kermit for the Northstar Horizon? Is anyone able to create an NSI image (double density single sided) that contains this binary, or the two HEX files in it? Or is there some magical incantation that I might be missing? I've got a very limited subset of programs on the CP/M boot disk: A>dir A: MOVCPM COM : CONFIG COM : ASM COM : COPY COM A: FORMAT COM : FILECOPY COM : DDT COM : ED COM A: LOAD COM : PIP COM : STAT COM : SYSGEN COM A: SAVEUSER COM : SETCPM COM : SUBMIT COM : XSUB COM A: DUMP COM : DUMP ASM : MEMR COM : MEMR DOC A: HORUSER ASM : USER ASM : DISKDEF LIB : READ-ME DOC A> Thanks in advance for any assistance!!!

PDP 11/40E and microcoding

by mark.kahrs＠gmail.com

I thought I'd change the subject line. Eric is of course correct, it's the 40 and not 44. I've had the 44 on my mind lately. The details of the 40E were given in an internal CMU report. This was poorly scanned by CMU and is available here: http://repository.cmu.edu/cgi/viewcontent.cgi?article=3241&context=compsci (and a hat tip to Paul Birkel for pointing this out). I will rescan the figures when I get my copy back from "interlibrary loan"). Wonder what happened to all that microcode written for Hydra???
