museum name contest

by legalize＠xmission.com

My friend who works with non-profits tells me that "Computer Graphics Museum" is too boring for fundraising. He wants me to come up with an alternative name that we can use. I'm open to suggestions. The point is to have a catchy name that (for instance) school kids will remember from their visit, or that will catch the eye/attention of donors who don't necessarily know anything about computing history. If your name is selected and you're in the continental US, I have a C=64 demoscene DVD I will award to you. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>

PS2Encoder Board Run

by brain＠jbrain.com

I'm planning to make a board run of my PS/2 KB to serial/parallel adapter: http://www.go4retro.com/2011/03/11/micro-project-ps2encoder/ I'm wondering if anyone who might use the item has any suggestions prior to my committing the design to the PCB fab house? * Among other things, rs232 signalling are TTL levels. Is that an issue? (I'm not sure how to add a level shifter without expanding the board size. * The board offers 24 pin DIP footprint and 2x12 headers for connections. Concerns? * The PS/2 connector is on the edge of the board, but can be wired up via pigtails. Is that OK? Any suggestions welcome. I am hoping to offer the board in PCB form, and in finished programmed form. I think the finished option would be < $20.00, if that makes any difference.

Remember doing exactly that 25 or so years ago. Wrote some process control software; CGA monitor on top of the PC and the MDA monitor hanging from the roof of the factory floor displaying bundling information. Machine control via the parallel port which required a tiny bit of assembler but the rest was QBasic. Doug.

As to hard disks, how many of your Z80 CP/M ST412/506 hard disk controllers had provisions for more than two drives? As to other interfaces I think SCSI and IDE (PATA) both allowed more than two drives per controller and predate SATA by quite a bit... m

PDP-12 flip chip layouts

by pontus＠update.uu.se

Hi My friends and I are restoring a PDP-12. It is in quite good condition but we are hunting down some errors in the CPU. We have engineering drawings but we would like to manufacture a new flip chip, M161 to be specific, That would be simpler and more "authentic" if there was layouts available. Was there ever layouts published? Or has somebody taken it upon the to scan circuitboards? Kind Regards, Pontus.

Altair 680 power supply...

by wh.sudbrink＠verizon.net

My Altair 680 has achieved the position of primary attention on my workbench. All of the ICs are socketed. Not having seen power in over 20 years, I did not trust the power supply as far as I could throw a bus. I pulled all of the ICs, attached dummy loads (automobile bulbs) and powered up. Sure enough, there was AC all over the place (where there should have been DC). I replaced all of the electrolytic caps and that got rid of the AC but some of the voltage levels are very wrong, at least as compared to what is written on the schematics. The worst offender is just off the "plus" side of the full wave bridge (BR-1). It should be nine volts but is actually at 11.5. This makes what should be the main five volt rail a little more than 9 volts... the far side of VR-1 (a 7805). The wave form coming off the transformer is really ugly not a smooth sine wave. I hate power supplies. I don't really understand, looking at the schematics, what this transformer should be doing. My guess is that it should be making a nice nine volt, 60 cycle AC sine wave with each of the two outputs 90 degrees out of sync? What could be wrong with a transformer that it would produce something like: __ / \ | \ / \_ / \ | / | / \_/ bent and very squared off at spots? My scope shows nice clean 120 coming into the transformer. How do I figure out a part number for a replacement transformer? Thanks!

TMA-11/TS03

by iamvirtual＠gmail.com

I believe you are correct Tony. It looks like dropping values into the TMA-11 registers while the processor is halted does not work. I had forgotten that I have a 873-YA bootstrap loader installed which can boot from a TM11 tape drive. I located a backup tape that was built using Rollin. I booted >from the tape and I did get the Rollin command prompt on the console. So it looks like the tape drive is in fact working. You are also correct that if the RK05 works (it does), the grant signals should be good up to the RK11 controller. My PDP-11/05 system with 32kW (28kW usable) now has a working RK05 drive with RT-11 v2C with MUBASIC and a TMA-11/TS03 tape drive. Once I hook up my ASR33 teletype, I will have an authentic 1972-ish system. Later, I will begin work on my PDP-11/20. That system was installed in Sept/1970. Many thanks to all who helped sort out my issues. --barrym Sun Aug 7 12:06:09 CDT 2011 Tony Duell wrote: >> To test the tape drive, I used the programmer's console on my PDP-11/05 to >> issue a read command to a mounted tape.

TMA-11/TS03

by iamvirtual＠gmail.com

With the help of various knowledgeable people on this list, it was pointed out that I did not have the connection to the tape drive controller in the correct position. To test the tape drive, I used the programmer's console on my PDP-11/05 to issue a read command to a mounted tape. When I issued a read command by depositing a command into the TMA-11 command register, the tape advanced slightly and then stopped. The 'Bus Grant Late' error was set in the TMA-11 status register. The status register did indicate the controller and tape drive were both ready. No data was read in. The read command was issued while the processor is halted. This particular system did not originally have any external devices hooked up to it. Beginning at the processor, the system has the following components installed: KD11-B PDP-11/05 LS11 line printer card (connects to a Centronics 101A printer) MM11-U 16K x 16 core memory MM11-U 16K x 16 core memory RK11-D RK05 disk controller (See http://www.iamvirtual.ca/collection/systems/minis/PDP11-10/Boards.html for details) The BC11 cable leading to the TMA-11 controller is put on the Unibus out connection at the last slot of the RK11-D controller. Based on previous posts from others, I suspect I don't have the processor grant set up correctly. I am currently reading several different manuals to get a description of how the grant lines should be hooked up. I have read many descriptions of the signalling, but I have not located information on where to use the Grant Continuity cards or making changes to the wire-wrapped bus. In my case, I will need to make changes to the bus, since I do not have any of the Grant Continuity cards ;-) Am I on the right track to assume that the problem is likely to be the processor grant wiring, or should I be looking elsewhere? Many thanks for any pointers! --barrym

Power Ripple in DEC BA11-K

by jkunz＠unixag-kl.fh-kl.de

Hi. I try to get my "new" PDP-11/34a back to live. I did a quick PSU test today with dummy loads. All voltages, LTCL, DCLO and ACLO where OK so I pluged in the logic boards. But the machine does not respond to the knobs on the programmers console. Pressing HLT + CNTRL brings the machine not to halt, but the "Bus Error" LED of the console lights up. Grant continuity cards and NPR jumpers are in place. It looks like I have the wrong bus terminator: There is a M9301-YF at the CPU side and a M930 at the other bus end. It seems I need a M9302 in place of the M930? This would explain the bus error. I took my scope to have a look at the ripple of the voltages. Here is what I got on the second +5 V PSU: X = 0.2 V / div ; Y = 2 ms / div http://www.unixag-kl.fh-kl.de/~jkunz/tmp/5_Volt_Ripple__y=0.2V__x=2ms.jpg X = 0.2 V / div ; Y = 10 us / div http://www.unixag-kl.fh-kl.de/~jkunz/tmp/5_Volt_Ripple__y=0.2V__x=10us.jpg I get similar pictures on all voltages. Both +5 V power bricks (H7441) show similar ripple as well as +15 V and -15 V. There are spikes with up to 1.2 Vpp and it is clearly related to the 50 Hz lines frequency. This doesn't look that healthy. I had a look at the BA11-K power distribution schematic. The two +5 V PSUs are independent and run of different windings of the mains transformer. I am a bit surprised to see about the same fault on all PSUs. I am no SM-PSU expert, so I am now at the point where I have to ask for advice. -- \end{Jochen} \ref{http://www.unixag-kl.fh-kl.de/~jkunz/}

RT11 w/ MUBAS is still operational :-) I never considered the fact that the bus inside the main system is so tailored to the cards installed within them, especially on a slot by slot basis. If I understand things correctly, the first RK05 drive cable is attached to the bus opposite the M7255 card. The RK05's are daisy chained together. The last RK05 has an M930 terminator. In the main cabinet, the M930 terminator opposite the M7257 card is removed and the BC11 cable leading to the 1st slot in the TMA-11 is installed. The M930 terminator in the TMA-11 now becomes the Unibus terminator. If the entire Unibus chain is <50 ft, then we are good. Are all BC11 cables the same? I see some with M919 connectors and others with M929? Many thanks! PS. I am still looking for an installable RSTS-11 (version 4 or LESS) so I can prep an RK05 drive under SimH where I can copy the image onto a real RK05 disk pack (I wrote some software to do this) --barrym

Looking for old Memorex gear

Memorex was the first independent disk pack manufacturer, beating Caelus by several months.

74H55 comprehensive data sheet

by tshoppa＠wmata.com

Page 7-24 in TI 1971 set: http://bitsavers.trailing-edge.com/pdf/ti/_dataBooks/1971_TI_IntegratedCirc… Expander gates will be about as clear as mud in the modern logic diagram sense if you look at a single chip. Make sure to look up the 74H60 or 74H62 which is the "other half". There was an early 70's TI TTL book (not so much databook but more of a cookbook/how-to book) aimed towards college students or guys new to TTL that illustrated expander gates in useful ways. By the 80's there are still pages in the TI databooks for the expander gates but you'd be stumped trying to decode them.

RK05 and TMA-11

by iamvirtual＠gmail.com

I am in the process of adding a TMA-11 tape controller with a TS03 tape drive to my PDP-11/10 system which has a single RK05 drive attached. There no other devices attached. I removed the Unibus terminator out of the RK05 and connected the BC11 cable in it's place. The cable then goes to the TMA-11 controller. The TMA-11 controller does have a terminator as well (ie. it is the end of the Unibus). Previously, the PDP-11/10 and RK05 worked as expected. Now that the TMA-11 controller is connected, the RK05 drive does not spin up. When the 'Load' button is pressed on the RK05, I do hear the door lock solenoid engage, but the drive spin up. If the system is powered down and the cable to the TMA-11 is disconnected, the drive does spin up. Any ideas on why the RK05 would refuse to spin up when connected to the TMA-11? I am just looking for some pointers to narrow my search. Thanks! --barrym

Hi all, I have reached a point where I must dissolve my collection. I have just reached this decision, so this email is providing a head's up as it were. It seems so many people reach this point then have to get rid of their collection within the next n (where n is <10) days..... I am in the process of making an inventory, but basically I have the following; System 1. VAX 400VLC, 26in? Color monitor, external storage and CD w/caddy System 2. VAX 3100-10 with Evans and Sutherland PS390 Includes connection to VAX, Evans and Sutherland Monitor, button box, Keyboard, Stereographic glasses and software. System 3. PDP 11/23 in a pedestal enclosure System 4. VAX 6000-440; contains 4 RA90 drives, two internal to the cabinet and 2 spare, integral infoserver and several CD drives and a TU81+ tape transport. OpenVMS 6.0 Con Dist. And the system that got me started in this hobby, System 5. PDP 11/23+ DECDatasystem Two Cabinet wide 19"Rack form factor; processor has been upgraded to 11/73. 3 Drives; 2 operational, one standby. 2X RD52 and a RD53. TSV05 tape transport & 2X RL02 Drives. I have numerous terminals for this system, Two Tek Graphics Terminals, a few VT type and an LA100. This system was used as a basis for developing micro controllers, to that end this system also comes with a secondary chassis, two LSI 11 Falcon boards, in the original packaging, a Mentec M90 (I think) PDP on a board, the original 11/23+ processor and several other modules. The software as I recall is RSX-11M-PLUS (V?), FORTRAN & BASIC Also comes with MicroPower Pascal for driving the external Microprocessors. The software comes complete with Licenses, about 10 to 15 RL02 disks, loads of tape and an Orange wall of Documentation. I also have a Qbus ESDI card and Drive, but have not installed those. I am Loathe to let these systems go. But I cannot keep them. I am offering them to the list first in the hope someone will keep them alive and continue to use them. I will be taking an inventory soon and will post that as I make my way through everything. Items are for local pick up only (Madison, WI). I am looking for Donations for this equipment, which, given how unusual some of them are, I think is warranted. If you are interested, please drop me a line at briandotcdotmichellatgmaildotcom Thanks for reading. Brian. ________________________________ The information contained in this email is confidential.

Gould Quadrabyte board set

by tshoppa＠wmata.com

> I ran across mention of the Gould Quadrabyte processor in a ca. 1980 > magazine product annoucement. > Does anyone know what CPU was used in these? I thought it was a boardset with a gate-array+bitslice+STTL CPU that came when Gould bought S.E.L.. i.e. not a single chip CPU. But... 1980 is before Gould bought S.E.L. right? So maybe I'm mixing things up. I don't think it was a mini-SEL-32 (I asked about this once in the 80's!) Tim.

Looking for old Memorex gear

by tshoppa＠wmata.com

> 3) Mark I, V, VI, X or XI disk packs I'm not familiar with those model names but I suspect I might know them as a "Memorex brand 2315 cartridge" or "Memorex brand 3330 pack" or similar. Was Memorex the first maker of IBM-compatible packs? Where did Caelus come in the scheme? For a while in the mid-2000's there was a Memorex brand USB keychain drive, which I swear was styled to look exactly like a miniature little disk pack. Not a very efficient of pocket space but wow, did it look like an old disk pack :-). > 4) A Data Mark module Help refresh my memory... Data Mark was Memorex's version of the IBM 3348? Head and positioner inside the cartridge?

floodgap temporarily offline (damn you Time Warner)

by spectre＠floodgap.com

For those of you using gopher.floodgap.com and the various Mac, Commodore and Alpha Micro resources on www.floodgap.com, thanks to Time Warner Business who promised me two weeks for the buildout and are now up to four and counting I will be offline completely starting tomorrow (as my current ISP contract was terminated based on their estimate). Services on those machines will be inaccessible until connectivity is restored, which hopefully should be in less than a week or there will be hell to pay. Hopefully Jay will not unsub me from the list :) but E-mail should fail over to my MX peer anyway. The inconvenience is regretted. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- There's always free cheddar in a mousetrap, baby. -- Tom Waits -------------

vms fortune from 1970s plus

by dgahling＠hotmail.com

This is a copy of late 1970s "fortune" from Vax/Vms of the time,with some additions. I'm still trying to find my original printout of the actual filewhich I'll post when I do. But I didn't want this lost, and some of it's amusing. Also several of the sayings are my fault or because of me or inspired by me.Some will live forever in infamy see: http://pastebin.com/RQz0ax0F Again, it's not 100% original, when I do find that one, it'll get posted.Maybe some here will recognize it. I may never live down some of the ones that are my fault :) Dan.

cleaning out databooks- any takers?

by trash3＠splab.cas.neu.edu

Before I forget, located in Wrentham, MA, which is near the MA/RI border. Doing more cleaning in the basement. Getting ready to recycle LOTS of data books. Before I do, I thought I'd check with the group first. I've already packed the Motorola, TI and National Semiconductor books. They took about 20 feet of shelf space and the packed weight is about 160 pounds for the three Motorola boxes, 100 pounds for the two TI boxes and about 80 pounds for the National Semi boxes. Still on the shelves are another 36 feet of books. Some examples of the larger collections are Analogic, 3 feet of Intel, AMD, Fairchild, RCA, Signetics (3 feet) and many, many others. A few books go to the early 70's, even perhaps late 60's, but most are in the 80's. I have taken pics of the packed books and I can take pics of the remaining shelves, if there is any interest. I'd really like to get rid of them all at once, but I'm willing to entertain breaking it up, just as long as it doesn't cost me money to ship(you pay shipping) or take too long to sort through and pick out singles. thanks, Joe Heck

Looking for Sun 3/110 CPU Board

Anybody know where I might be able to find a Sun 501-1134 or 501-1209 3/110 Motherboard? I've got one that's got flaky RAM, and while I try to find the defective components, I'd like to find a replacement in case it's not something easily repairable, so I can keep the system operational.

Got 2, Epson HX20s; One available for swap; Bull Gamma10 Boards

by oe5ewl＠gmail.com

Hi, got 2 HX20s in carrying cases yesterday. As far as I can tell the displays work. The Cassette Drives spool and the one machine I tested loaded a program. The internal batteries are dead but exchangeable to more modern rechargable cells with little effort. I'd like to swap the second HX20 for some radio gear (a Stornophone 6000 for 2m VHF for example would be a great deal). The available HX20 comes to you with a carrying case, a bit of printer paper, a Wall-Wart(original) and the cassette module on the right; german localized keyboard. The little computer looks nice and clean but is rather untested (it switches on at least and brings the 1 Monitor 2 Basic menu). I can throw in a micro-cassette or two if you want. There were some Bull marked printed boards in this lot, likely from an old computer which are available for any interested people too. I don't have any idea what this boards are but I think these are 60s PCB-Design. Every board is a c (abt. 15cm sidequadratis) and has some little doughter-boards soldered onto. I'll post pictures in the evening. http://www.technikum29.de/de/rechnertechnik/gamma10.shtm has an Image of One of the cards I've got too. I have 5 or 6 cards in total. Available to good hands. Regards, Wolfgang <offtopic on> With the HX20s came an old Eminent Type-80 Electronic Organ. I found nearly nothing about this particular model but would need some schematics or hints to repair this one. Should bring nice sounds as it is a full tube model. Anyone a clue where I could get some more information <offtopic off> -- Wolfgang Eichberger - OE5EWL Operating System Collector Blog: 5ewl.blogspot.com Homepage: www.eichberger.org

Operating Systema for one HP Integrity Server (model 1620)

by spedraja＠gmail.com

Hi. It's possible for me to obtain one HP Integrity Server (model 1620). As HP said in its website, it supports Four Operating Systems: HP UX 11i version 2, Linux (RHEL 3 Update 3, RHEL 4, SuSE SLES9), Windows Server 2003 Enterprise and Datacenter Edition, and OpenVMS V8.2-1 or higher. Most interesting options for me are HP-UX (I know and manage it usually) and OpenVMS. Some way to obtain them for an affordable (yes, yes, good question about the meaning of affordable...) price ? Thanks. -- Saludos - Greetings - Freundliche Gr??e - Salutations Sergio Pedraja <http://www.linkedin.com/in/sergiopedraja> twitter: @sergio_pedraja http://www.linkedin.com/in/sergiopedraja http://www.quora.com/Sergio-Pedraja https://www.xing.com/profile/Sergio_Pedraja http://www.viadeo.com http://www.avalonred.com/ -----
