Can anyone tell me what kind of connectors these are? http://yahozna.dyndns.org/scratch/imlac/connectors.jpg This is on the rear of the Imlac. I need to build a monitor cable to rig up a Tek X/Y display(the original display is long gone) and I haven't had much luck finding a mate for the receptacle on this thing. It'd help immensely to know what they're called :). Thanks, Josh

TK85K 01 Cartridges

by jgessling＠yahoo.com

Searching through some boxes, just found several of the DECtape III cartridges I can offer to the world.? All stored since about 1997 in cool dry area. 6 in the original shrink wrap, never opened 3 never used, not in shrink wrap 5 used, apparently data from that time period look to be in good shape 1 case only, no actual tape, I wonder where the tape went? I can ship USPS flat rate from 94597 for shipping plus a few bucks to make it worth my while to go down to the PO. Contact me if you are interested, Thanks, Jim

introducing the Media Archaeology Lab

by lori.emerson＠gmail.com

Hello all, I wanted to move from lurker to...whatever the opposite is by introducing myself and the Media Archaeology Lab (MAL) I run. I'm thrilled to discover your listserv as I'm learning a lot just by reading your posts and I think many of you will be interested in the MAL. http://mediaarchaeologylab.com Founded in 2009 and housed on the University of Colorado at Boulder campus, the Media Archaeology Lab houses obsolete media from the early twentieth century to the twenty-first century for hands-on research, teaching, and research creation. I've come to see that the MAL is a remarkable configurable conceptual object that, depending on how you approach it, houses items for research and teaching, items that actually generate research; is a site for artistic interventions, experiments, projects; is an archive for media objects; is an archive for original works of digital art/literature along with their original platforms. It belongs equally in literature departments, art departments, media studies departments, history of technology programs, computer science departments, libraries and archives. The MAL is a "living archive" in the sense that, other than our stockpile of spare parts, everything in the lab functions and is meant to be turned on and used for tinkering, play, teaching, and research. It is also living in the sense that it is an ongoing, DIY project primarily run by and for the self-taught that continues to grow and change with every new influx of participants. In fact, one of the strengths of the lab is that there are almost no precedents for it and no clearly established set of best practices. The MAL's strongest collection is its historically important personal computers from the late 1970s through the 80s and 90s - computers such as the Apple II, Apple Lisa, and Apple Macintosh, as well as many early works of digital art/literature from the early 80s through the late 90s. If you'd like to know more about the MAL or if you'd like to donate, please visit our site: http://mediaarchaeologylab.com yours, Lori --- Lori Emerson Assistant Professor | Director, Media Archaeology Lab Department of English, University of Colorado at Boulder Hellems 101, 226 UCB, Boulder, CO 80309-0226 loriemerson.net | mediaarchaeologylab.com

cctalk Digest, Vol 122, Issue 5

by elson＠pico-systems.com

Date: Thu, 3 Oct 2013 21:31:23 -0400 From: Jonathan Katz <jon at jonworld.com> To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: OLD SGI hardware... Message-ID: <CAEOZr+06MyaAAxCY8z1K7gHCQX+-aHJEv7dorp2QwVeKuVDvKA at mail.gmail.com> Content-Type: text/plain; charset=ISO-8859-1 Sorry to keep pestering the list. I have an idea... Is there any really old original SGI hardware out there? I'm talking the pre-MIPS stuff, that was used as a graphical front-end to VAXen and other items (IRIS 1000) or even IRIS 2000 equipment. I had an Iris 2020 some years ago. It had a bad geometry engine and was thrown out at work. I got a guy in Germany to send me all the cards he'd saved out of one, and got it running. It lasted about a year and the geometry engine quit again. I sold the boards to a guy who supported some old gear at an air force base in Alaska. They are apparently still using this stuff. Jon

Data General One, EL backilght version

by shadoooo＠gmail.com

Hello. I have two similar Data General One, one with fixed disk, the other is the two-floppy version. Both came with no manual or disk unfortunately. Trying key combinations, I found the CMD-+ and CMD-- way to turn on and off the EL backlight, while CMD-LARROW and CMD-LARROW changes contrast. Any other useful key combination? At power on, the two floppy version doesn't boot (no floppy disks), but it shows a BIOS menu where we could format floppies and use the machine as serial terminal. Nice! I tried to format a floppy (720k or 1.44M) on both floppy, but with no luck, it doesn't work for some reason... :( No way to boot the machine from a previously written 720k disk. I don't understand what the problem could be. Any similar case anybody? The fixed disk version boots nicely the MSDOS still installed on the HD. It seems to work fine. This is a customized version for Allen-Bradley, it has also a big D-sub connector with three rows of pins on the back. It has also a memory expansion in the back slot, with a total of 640K+896K detected at boot (1.5MB total). No way to enter the BIOS menu however... maybe it's missing in this version? Anybody have a scan of the manuals or images of floppy? Thanks Andrea

DEC TSZ07 ..relabeled Cipher 9 Track tape?

by holm＠freibergnet.de

Hi, I know that the DEC TSZ07 9 Track drive is made by Cipher. Does someone here know if there is a near equivalent Cipher Model? The Cause of my Question ist, that I think I have a ugly fault in the PSU, when the Drive is in standby, some parts of the circuit are overheating. Look here for pictures: http://www.tiffe.de/Robotron/TSZ07/ I've repaired the PCB but the parts are still getting hot in standby, because standby no fan is running.. Since the Technical Manual of the TSZ07 contains no schematics, I've looking for the equivalent Cipher model to find schematics of that PSU... Kind Regards, Holm -- Technik Service u. Handel Tiffe, www.tsht.de, Holm Tiffe, Freiberger Stra?e 42, 09600 Obersch?na, USt-Id: DE253710583 www.tsht.de, info at tsht.de, Fax +49 3731 74200, Mobil: 0172 8790 741

Hi all, There's a new version of "PDP11GUI", the graphical development environment for PDP-11's. V1.38 has new features and fixes some bugs, see history.txt Most important changes are - a bug fix in the PDP-11/34 console emulator interface - the Memory Loader supports paper tape images, so you can run all stuff in www.bitsavers.org/bits/DEC/pdp11/papertapeimages/ - there's a Memory Test Windows, which tries to find bad chips with EXAM and DEPOSIT. - COM ports 1..32 are supported, which is necessary for those USB adapters Download from http://retrocmp.com/tools/pdp11gui (Attention: the old stable v1.31 ist still there) If you find new or old bugs, please let me know ... testers are welcome!

N8VEM PCB cats and dogs

by lynchaj＠yahoo.com

Hi! I have a few remaining "cats and dogs" PCBs looking for a good home. If anyone is looking for the following: 1 ECB ColorVDU (last one!) 2 ECB 6x0x host processor (2 left) 1 ECB MSX cartridge reader (1 left, probably will get some more interest now that N8 PCBs are available) 2 ECB SCG (2 left) (Sound, Sprites, and Color Graphics for TMS9918 video and AY-3-8910 sound) 1 ECB bus extender (1 left) very handy for those with an ECB card cage 3 ECB Cassette interface (3 left!) Kansas City Standard -- read those old data cassette tapes before they crumble to dust! 1 S-100 Parallel IO (1 left!) These are all good boards to build. It would be nice to move some of these which have been sitting here on a shelf all sad and lonesome. They'd like to find a new home on some builders workbench! Thanks and have a nice day!

Looking for DECtalk DTC-01 v1.8 and other non-v2.0 firmware roms

by jgevaryahu＠gmail.com

I know that the original vt240-molded-case DTC-01-AA DECtalk had multiple firmware versions, but all units I've ever seen have had the v2.0 (i.e. the final) firmware installed. I know at least version 1.8 existed in older units, and was wondering if anyone here has a DECtalk DTC-01 with firmware 1.8 (or any version other than 2.0) in it. It should speak "Dectalk version x.x is running" when powered up. Bill G. had or used to have a v1.8 unit, but I can't manage to get in contact with him and I don't know if he still has it. At least one other person on usenet had a v1.8 unit where the eproms all bitrotted to blank after a while. P.S. I'm also hunting for DECtalk DTC-03 (decmodem-rackmount) firmware versions; there are at least three, maybe as many as six different firmware versions for those cards. -- Jonathan Gevaryahu jgevaryahu at gmail.com jgevaryahu at hotmail.com

accepting S-100 RAM&ROM pre-orders

by LYNCHAJ＠YAHOO.COM

Hi! Now that the S-100 6502 CPU V2 and S-100 Parallel IO PCBs are winding down it is time to get the next PCB order rolling. We need 20 PCB pre-orders so I can make a manufacturing order. The S-100 RAM&ROM board is ready for "production". If you would like to get one or more of these exciting new S-100 memory CPU boards please do the new usual pre-order. I will set aside your board so you get them as soon as they arrive. Here is a link to S100computers.com website with information on the new board. Basically it is an 8 bit/16 bit fusion of the S-100 4MB SRAM board and S-100 EPROM board which addresses major issues with each board. Overall this is a much better and more flexible memory board that should be a general solution for almost all your S-100 memory board needs. http://www.s100computers.com/My%20System%20Pages/RAM&ROM%20Board/RAM&PROM%20 Board.htm The PCBs will be $20 each as per the usual arrangement. Shipping in the US is $3 for a single PCB and $2 for each additional PCB. Shipping internationally is $10 for a single PCB and $3 for each additional PCB. This is for the bare basics USPS first class postage with no tracking or insurance. The builder assumes all risk of delivery as per usual arrangement. Please send a PayPal to LYNCHAJ at YAHOO.COM and I will reserve your board(s). Thanks and have a nice day! Andrew Lynch

Collection to sell

by jlw＠jlw.com

There's a chance that the Sun 4/260 in the collection was once mine. I had it between about 1993 and 1997, in Mountain View, CA. I eventually grew tired of the noise and bulk sitting in the dining room, and offered it to interested parties. Barry came by to pick it up, along with the Fuji tape drive, and a loose SMD drive or two, plus the 4119 color monitor and about 50 feet x5 coax to put the monitor far away. He had an online museum that he was going to put it in, somewhere in the Santa Cruz mountains. I don't see the SMD controller in those 4/260 pictures though, and I didn't take the SMD pedestal when I got the whole machine in a fire sale for five bucks. I'm pretty sure I don't need it back. :-)

Disk Format for Rockwell System 65?

by marvin＠west.net

I'm cleaning house (again/still) and found two disks in the Rockwell System 65 I have. So far, I have found no docs/schematics on this machine. If they are the system boot disks, I'd like to get them archived with a disk image to help others who might have one of these systems. The drives themselves are Shugart Model 400 floppy disk drives. Does anyone know what it takes to read the data and/or make a disk image on these disks?

AIX for PS/2?

by jon＠jonworld.com

Some posting on another list gave me a hankering for wanting to try to get the old AIX for x86/PS2 systems running in a VM. I have two old Floppy disks (3.5") labelled AIX BOOT and AIX INSTALL ... the BOOT disk boots but doesn't give an option for installing from the install disk. The install disk doesn't really seem to boot. I assume there are more than just these two disks to get the OS running. Anyone out there have a source? -- -Jon Jonathan Katz, Indianapolis, IN.

Free Sun items for Sun 2 and Sun 3

by silvercreekvalley＠yahoo.com

Clearing my storage unit and have a few bits and pieces of Sun stuff if anyone is interested. All items are not tested, so for parts only, and they are free but collection only. I have some pictures. Sun 3/60 - seems complete with colour frame buffer and memory Sun 3/80 - case, motherboard, floppy drive and PSU only (no memory or HD) Sun 3/80 - case only Sun 2 monitor on swivel pedestal. This looks to be mono ECL but serial number is hard to read so not sure. Hard to find these days. A large CPU board - I think from a SPARCserver of some kind (501-2055), it is fully populated with memory, has an SBUS card (frame buffer possibly), and two CPU modules fitted. A boxed Sun keyboard (probably Sun sparcstation era). Collection from South bay area (near San Jose, CA). All items free. Prefer someone to take everything in one go. Email me if interested.

WTB Apple 2 Serial Card?

by jon＠jonworld.com

All, The subject says it all. I have a ton of data on an old Apple 2 I'd like to get off of it. I tried ADTPro using the audio/tape ports on an Apple ][e but I could never get it dialed-in correctly. In all honesty, I just want the ASCII content out of a bunch of word processing files; I don't need to transfer disk images. I figure if I can "print" those documents over a serial port, through a null-modem cable and into another system I can capture the ASCII as a text file and be done with it. Does anyone have one laying around that could be put to good use? Thank you! -- -Jon Jonathan Katz, Indianapolis, IN.

The large number of serial ports is unusual in a Z80 as with 64K memory there's a limit to what you're going to talk to. I wonder if MP/M was available. that would be terrific. If you're using a terminal I would use a straight-through cable rather than the null modem. A computer to terminal set up is DCE to DTE in the eyes of RS-232 and so no cross overs should be needed.

Sperry 3070-08 PC

by jules.richardson99＠gmail.com

A long shot, but does anyone happen to know the [external] DIP switch settings for a Sperry 3070-08 PC (a bit of googling suggests it's a Sperry "HT")? I think I may have accidentally flipped some of the ones on the back of mine - the system's now stuck in a repeated-beep loop with no display init, so possibly it's looking for RAM where there isn't any (OTOH, it just moved locations, so I'll re-seat boards etc. just in case - but I'm reasonably sure that I caught the switches at one point, so it'd be useful to know where they should be set at for my particular config). cheers Jules

Hi all, read a lot about them lately, but never saw a real one :( Did they really all go to the land fill? Anybody out here has a spare one to sell/share/swap/etc.? Grew up with the mc68k, and definitely would like to have one of those ...

N8 PCBs are here

by LYNCHAJ＠YAHOO.COM

Hi! Good news! I ordered a batch of the N8 PCBs. The N8 is a group project design from the N8VEM home brew computing project. I received some questions about the N8 so I am sending this bit of background on the project. The N8 project is on the N8VEM wiki and mailing list. I had previously offered the PCBs there and here on VCF directly to builders. However now I am also putting them up on VCGM to help get the word out a little better. The N8 is intended to be a "home brew" style computer in the style of early 1980's all-in-one home computers with a usable set of features such as color graphics, audio, an assortment of mass storage options, a variety of ports, etc. Although a bus expansion is supported no additional boards are required. The N8 is designed so builders can assemble it themselves using common tools such as basic soldering iron, VOM, etc. It is a simple two-layer board construction using all commonly available plated-through-hole (DIP and PLCC) components without requiring any SMT skills, programmable logic devices, etc. A quick summary of the N8 features: Processor & memory: Z8S180 CPU (Z80 compatible, 33MHz max), with 1MB SRAM and 512K Flash boot ROM (in-circuit reprogrammable) Primary Interface: Color video (TMS9918A), Sound generator (AY-3-8910), and PS/2 keyboard and mouse ports Mass storage: IDE drives (including CF adapter) port, Floppy drives port (1.44MB 3.5"), and SD socket Expansion I/O: Two Serial ports, Parallel Printer port, Two MSX compatible Joystick ports, RTC w/NVRAM (configuration data), RS-485 networking port Various diagnostic LEDs, "front panel" status indicators, buttons, with optional debugging hex display and keyboard (DSKY) A builder has also designed an enclosure for the N8 http://n8vem-sbc.pbworks.com/w/file/52623834/N8%20Case%20Construction.zip Photos of prototype enclosure http://groups.google.com/group/n8vem/browse_thread/thread/e7cf446f1e33760c# There is an MSX BIOS ROM image (in development) here http://groups.google.com/group/n8vem/browse_thread/thread/c880ea6aa13ccff7 There is a Z-System ROM image (in development) here http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder?m=RomWBW The PCBs should be here in mid to late Jun 2012. http://n8vem-sbc.pbworks.com/w/browse/#view=ViewFolder?m=N8-final Click to view PLOTS of PCB https://www.freedfm.com/freedfm/0011697403232210/results/plots.htm The N8 PCBs will be the usual $20 per PCB with $2 shipping in the US and $5 elsewhere. I am offering the PCB only. No assembled units as this is for home brew computers. Most of the chips are available through Jameco, Digikey, etc. Some of the specialty chips like the AY-3-8910 and TMS9918 would have to come from eBay, UTSOURCE, Unicorn Electronics, etc unless you have those on hand. I don't know what the final assembly cost would be and it would depend a lot on how you build it. Styles differ dramatically and depending on your supply of parts could vary widely. Several builders have working units on the N8VEM mailing list so I suppose you could ask them or look up costs on the parts list/BOM from the wiki. Since it is an all-in-one design rather than multiple boards there are a *lot* of parts stuffed into the 60 square inches of PCB. However there is only one PCB. There is some efficiency gained by stuffing everything into a single board rather than spreading out over several boards on an ECB backplane. The N8 is a bit like the P112 SBC except it is all DIP/PLCC (PTH PCB assembly, no required SMT) and has richer IO options like video and sound. It is larger though so it is a bit of a trade-off. Thanks and have a nice day! Andrew Lynch PS if you want to see detailed close up photos of the N8 prototype in its enclosure then download the large ZIP file above on the N8 Case Construction. Great photos of the system (credit to Dan)

Fixed Mac128K board (was Re: Repairing Mac128K board - memory problems)

In anticipation of pulling and replacing 1/3 the DRAMs on this board, I tried the trick of a dry-fit piggyback with known good chips on the locations marked as bad. I can report 100% success. I stuck 6 new chips on the 6 bad chips and got past the Sad Mac. In the light of the several reports I found on support forums, all I can imagine is that if these people replaced their bad RAM chips, either they misread the conversion table and replaced the wrong chips, they damaged the chips or the mainboard traces during the repair process, or they just have a bunch of cold, dry solder joints. Present state: machine gives "bong" when turning on (it always did), usual screep wipe happens, then the "[?]" disk icon flashes. I have one 400K drive, an OA-D34V-22, and (for now), Rev A ROMs. This combination does not work. It tries to read disk, ejects it, then asks for another one. I already have the -B ROM images and just need to burn a pair of 27256s since that's an easier path than locating a working, original revision OA-D34V drive mech. On the OA-D34V-22 I do have, it did require removing petrified grease from the old eject mechanism. I have some white lithium grease I'm contemplating using unless there is some magic grease the job requires. So the repair is nearly complete. Bad trace/repair damage found/fixed, bad RAMs identified and tested, and a couple items to complete to finish the job. -ethan

Does anyone have any information about this CIT-467 terminal?

by me＠GarrettMeiers.com

I have a C.Itoh CIT-467 Terminal. I've been able to find almost nothing about it on the Intrawebz. Was hoping someone might recognize it, or could point me in the right direction about finding a manual for it, or knowing what it's capabilities are (besides it obviously being a serial terminal). I've not even turned it on yet, wanting to find some more information about it first. I don't have a termcap entry for it, or anything close to it, on a few Linux systems I've checked. Any help would be appreciated! https://www.dropbox.com/sh/rlb1j1jcqqwffrf/t-O8t_8_L4 T ?hanks, ? Garrett Meiers www.linkedin.com/in/theunixguy

Hardware parsing of BASIC?

by derschjo＠gmail.com

So Iwas taking a closer look at the HP 1351A "Graphics Generator" I have. It's currently in operable condition, except that it won't draw text (apparently there's something wrong with the character generator, the :TX commands do nothing at all). I was surprised to discover that the 1351 (c. 1981) doesn't containa microprocessor or microcontroller of any kind -- all parsing of the command language it supports is done in hardware (TTL). (The service manual contains this gem: "The 1351A only accepts commands listed in this manual and in the Operating and Programming manual. Any others, especially those mentioned above will 'lock up' the 1351A such that it will have to be re-initialized...") At any rate, this reminded me of something that I'm prettysure I read here on cctalk years back, but I can't seem to find any reference toit anywhere; there was a computer designed at some university that ran an interpreted language (I'm pretty sure it was BASIC), on the metal-- that is, much like the 1351A and its vector description language, this machine's hardware parsed BASIC program text and executed it directly, rather than implementing some machine language. Does this ring any bells, or am I insane? (It's quite possible that both of these things are true...) - Josh

Hello Holm, I hope you find some part to repair your tape system! If the NEC disks you found have SMD interface (two flat cables, one is wider) and you don't need it, I would be glad to buy it. Thanks Andrea
